8:26 the problem is that because the projectiles of the cannons get fired at 120 relative to you once you reach 120 the projectiles move towards you relative to the map, not away from you so the game thinks you‘ve been hit by the projectiles
yep. and by aiming cannons more to the side you can get more max. speed, but less acceleration. I have a glitchless vehicle with logic gates to turn cannons just right so they don't explode, reaches 240.
I did not expect canon shots to maintain momentum from the vehicle, this is what makes them fly backwards. It's like you jumping away from the train but you still get dragged in the trains direction for a bit.
@@DianaTheLance Ok maybe I got it wrong but let's just say that the cannon ball gets shot forwards with a max speed of +120mph but the cannon is moving at -130mph (opposite direction from the shot) doesn't that make it go -10mph (back into the vehicle)? Talking about the game physics not irl.
@@danser_theplayer01 From looking at other comments, I think the cannons hit themselves is because the game does the math, gets the velocity, and then checks if it should hit anything. The problem seems to be that it ignores the velocity of the object it might be hitting, so in this video, the vehicle matches and exceeds the cannon's projectile speed, and the game then sees the cannon's projectile going towards the location of the vehicle, but it ignores the fact that the vehicle is moving away from that point and decides it got hit anyway. This is probably not super hard to fix though, it's just interesting that this doesn't show up much as cannons usually shoot forwards.
@@DianaTheLance if you shoot a nerf gun aimed behind you that shoots at 60mph and your car is going 69mph the moment the dart exits the barrel it just drops because the 2 forces cancel out same with the cannon the faster he went the closer it got because of was reducing the actual velocity of the shot after exiting
As stated by others, the reason for the exploding is that Trailmakers doesn't account for vehicle momentum when shooting the cannon. The cannon has an initial projectile speed of 120mph, so if the cannon is pointing in the opposite direction to motion, the bullet will collide with you when you go 120mph. In your second design, the cannons were tilted at about 45deg. Your new max speed is 120/cos(45), or ~170mph. The more perpendicular the cannons are to your vehicle's movement, the higher this limit. Edit: Smart idea by @bryanlandwehr7422 - _"120/cos(81) ~761mph_ _In theory, you could adjust the angle of the cannons based on the speed. Set them to 45deg as you start up, and slowly move them towards 82deg."_
This seems like the best explanation so far. And, if it's correct then Scrapman's vehicle could still be possible as long as the cannons were at about 81deg (almost perpendicular to the direction of travel). 120/cos(81) ~761mph With any amount of cannons, it would probably take a long time to get up to speed since the component of recoil along the direction of travel is so small. In theory, you could adjust the angle of the cannons based on the speed. Set them to 45deg as you start up, and slowly move them towards 82deg.
At the beginning of the video, the explosions kept getting closer to the car. The cannon shoots the ball at the same speed every time. Then, as the car reaches that speed, both car and the ball go the same speed(the forward speed of the car cancels out the backwards speed of the ball) so the ball stays close to the car and hits behind it making it explode. The Action Lab made a video explaining this phenomenon. It’s a great video. Everyone should watch it.
I think I know what happened. Cannonball as created get velocity up to 120 mph. When your vehicle hit 120 mph, from cannon perspective bullet has initial backwards velocity -120mph and cannonball had +120mph cannonball was expoding in innitial point.
I don't have Trailmakers but I gots an idea. You remember the kinetic drop with the gimbels? Stay below max speed when the cannons are firing, and when you reach a sufficient altitude, nose dive. I know I'm using semantics, but you have to start somewhere.
This reminds me of the orion drive. Which of course means it is best to add a suspension system to space out the accelerations caused by massive explosions into something a bit more uniform.
the canon and gun in trailmakers are made to point forward, and to keep you for shooting your self when going fast forward the bullets spawn further ahead, but they keep doing that even when they point backwards, so the faster you go the faster you blow your self up

The reason why this creation won't work is be cause when you angled the cannons when you reached the speed when they blew you up you were goning so fast that the projectiles didn't move far enough away from the cannon behind it so it hit the cannon behind it a solution might be to make the craft really wide in the front and have it get thinner towards the back.
I think what's happening is when you get faster the speed of the can't projectile gets slower because it stars leaving the canon at the same speed of the car, eventually it just drops and blows up next to you.
its because the game (probably) has code that makes the cannonball keep some of the speed of your car, i only know because of how much techno hated when the devs added this to ender pearls and snowballs.

The maximum speed of the cannonballs is set hard in the game. If they surpass 120, they explode (collision assumption by the devs maybe?). When angling the cannons, due to the angular offset it takes more forward speed (in this case about 170) for the cannonballs to gain a speed of 120 in their fired vector. Hard trigger to explode at >120 MPH. Not much you can do there.
I believe the reason for the self destruction is the cannon ball spawns inside the cannon and if the speed is equal to the velocity the first impact calulation is still inside the vehicle
15:50 the reason why it exploded itself was that your plane/can was moving faster than the bullets,this caused the cannon behind to explode since the bullet hit it
By the way, I just wanted to let you know that terminal velocity is not regarding any movement versus drag, it is the pull of gravity versus drag, I have heard you use it in the first way, now and before, as well as others so I just wanted to clear that up.
The reason why they explode is because the cannon shot gets a +120 mph on how fast your moving to determine its velocity, so if your moving 120 and you fire the cannons directly back it will make the cannon shot not move and hit your craft cause it’s spawn is inside the muzzle of the cannon, also why you can’t stack them. Most games have the shot spawn right outside of the character hit box to prevent the ‘exploding’ from happening.
My theory is, the faster you go, the closer the explosion. It's either because the projectiles are colliding, or the more plausible answer, is because; the projectile appears in front of the direction you're going depending on your speed, then it has a fixed time of when the projectile arms itself (armed: colliding with anything, it will explode) timed when it should clear the cannon's tip, with this regard, the faster you go, the more 'in front' the projectile appears, and since you slow down after reaching a higher speed, the projectile arms itself before it has cleared the cannon, causing it to self-destruct at higher speeds.
The reason why the cannon fire kept getting closer as you were getting faster is the Cannons fire with a constant velocity has you are speeding up and the your velocity approaches the velocity of the cannon fire the cannon fire won't be able to go anywhere like how you can run off the back of a moving car and if you're moving at just the right speed you'll hit the ground with the no net force
I was laughing so hard scrapman is confused by physics. Once you go the same velocity in the opposite direction of the bullet exit speed out of the barrel the bullet ground speed is 0 and fall straight down.
I think it is because you normally put the cannons on front but they shoot out at 120 so if you go that fast they collide with you, so the devs made it so that if you go higher than 120 it adds to the speed of the cannon projectile in the direction of your vehicle. At least thats what i THINK.
6:00 Game dev here, most of the other comments are wrong regarding why you were hitting yourself. This happened in my own game. They are correcting the bullet speed deppending on your vehicle's speed, as to avoid shooting yourself when flying faster than your own bullets when they are fired forward. Somehow, they made it so that the frame you shoot the cannonball, it materializes inside or in front of the modules of your vehicle, making it detect the collision with yourself. This is most likely because they are handling the input or cannons shooting in the Update() function of Unity monobehaviours which happens in every frame, and the cannonball is working in the FixedUpdate() because it uses a rigid body with physics, which happens at a different frame rate at fixed intervals. It can also happen between two separate game objects that work in the same update method and still have the issue of overcorrecting for the object's speed to avoid hitting yourself when you are flying and shooting forward. Edit: if you want to make this easier, I would consider asking the developers to fix the self destruction issue to begin with.
This is following real world physics, just the cannonball explodes on contact, and it contacts the barrel of the cannon. ua-cam.com/video/BLuI118nhzc/v-deo.html This video by mythbusters showcases this effect
@@grimdagoblinmain This effect is correct, but it's not meant to register a collision with the vehicle itself. If something, it would still take about a second for the projectile to hit the ground since the vertical velocity starts as 0 and it's quite some distance from the ground.
The explosions get closer and closer to the car as you get faster due to the 120 relative and you start going faster than that so unless you change the hit boxes or use a million glitches it’s impossible
im pretty sure the cannon projectiles are flipping around in the middle of their path because their velocity is either a) relative to the map or b) because they have actually have a net forward velocity (because youre moving faster than the cannon muzzle velocity) meaning theyre spawned in backwards and maybe since its the front of the projectile they connect and explode? edit: hypothesis 2: Having seen the 180 limit at 14:20 i think its because the vehicle is slowing down just enough to collide with the cannons that dont have aerodynamics
the projectiles inherit the vehicle's speed. Their muzzle velocity is 120, so when you reach 120, you cancel out the projectile's velocity from the cannon and the projectiles instantly hit the cannons, blowing them up Yay for Realism!I love when these things are in games to make them more realistic.
The cannon balls would never explode in contact with the cannon itself, the difference in speed between the cannonand the projectiles is always the same, they'd need to hit an external target. It's just bad coding, nothing more
i've tried to strap every type of cannon on a rocket firing straight down, but every time the result was the blow up themselfs from tank cannon to tiny cannon way before the barrier. And the dispensers don't really have much to begin with. But hey, keep making the awesome content.
I think the game itself is reading the cannons as forwards facing; the game doesn't care about where the explosions are happening, it's just reading how fast the vehicle is going and calculating how far away teh projectile should be going from teh cannon, and it's set up so that higher speed means the cannon's projectile gets closer until you get blown up by the explosion.
The issue here can be tested by creating a engine powered vehicle with a canon facing backwards. Once the vehicle reaches 120 mph, fire the canon. If you blow up, then you know it's impossible.
everyone else has said it, but ima also say it cause why not: if the cannons fire at 120 kph, and your travelling at 0 kph, then the cannonballs get shot away at 120 kph. but if youre moving at 60 kph and you shoot a cannon, it gets shot out at 120 kph, but at only 60 kph relative to you. if you are then moving at 120 kph, and you shoot a cannon, the ball moves at 0 kph relative to you....and kills you. its a simple equality of velocities, but thats why its maxed out. ps: i mainly know this because a mythbusters video 😉
the recoil movement is similar to the explosion thrusters where an explosive element would be launch behind a spacecraft and when it detonates the force would push the craft in the given direction... unfortunately as most of us know anything that involves explosives is 1. unreliable and 2. unpredictable attach such a device to a space craft costing billions and you've got a very dangerous and expensive firework... if you wish to create a vehicle that can travel at the rate of sound then i would suggest more conventional methods... but in the case of experimenting this is where sandbox games come in handy... as you can blow things up in a virtual world without the worry of accidentally destroying real objects
basically, once the cannon reaches a certain velocity (120 in this game(its like this in others similar too)) the cannon will fire, but the cannonball or projectile causes an error and seeing as it detects too fast for it, the game think you got shot
I think what happens is the faster you go the less accurate the canons get, so eventually they get so inaccurate that it somehow shoots sideways/ backwards
I did this once. I also glitched out the game with the exact same creation. Funnily enough, using only one rotating servo and a lot of cannons can do a lot to the game.
Maybe a sort of triangle with the back open, cannons facing backwards, on the inside and outside, should help with air resistance, deal with the exploding, and go fast
I have an MM idea. Trailmakers chase but the chasers weapons are your sticky mines and the fugitives is the explosive spike strip. Chasers use your vehicle's, fugitive builds their own vehicle.
the problem on land is that the front wasn't heavy enough so then the cannon recoil tips it up which makes the whole thind do a wheelie causing the cannons to shoot closer to you as you speed up because of the increase of the angle
honestly i have no idea what you guys are talking about but im loving it xd no but fr i used to watch scrape back in the day of when they used to play golf
As far as I can tell, the problem with the first vehicle is that the front was lifting up and tilting the cannons down ever so slightly, causing the shots to land closer
This challenge was unfortunately doomed from the start because cannons have a set shooting velocity and you either add to it by moving in the direction the cannon faces or take away from it by moving opposite. Having the cannons straight back means you equal out with the shoot velocity sooner and it just explodes on you, same thing for having them angle it just takes longer.
here is an idea to get more cannons: at the spike connectors to the back and make a seperate part that has it on both, that will allow you to make infinite amounts of cannons
The reason the explosives are getting closer is because the front of the car is too light, it’s lifting up out of air resistance relative to the speed from the recoil of the cannons
The reason you get hit by the explosions is because when you move faster the bullets go behind you fasten and when you hit a certain speed they can’t get out of the way of the other cannons in time
What you need to do is time the cannons so they fire a different rate so the speed is continued through the shots. That might make the "car" faster and maybe not blow it up
The way your car was built the faster you go the more you lift off the ground and since the front of your car was lifting off the ground, the cannons were shooting more twords the ground directly behind you
@4:26 I think it's a question of inertia. The explosions are propelling the car forward, however, they are also pitching the car's nose upwards, leading to the closer explosions. So, it could be back heavy or not enough down force.
Nevermind, saved by the comment section: DatBubby pointed this out: 4 days ago (edited) As stated by others, the reason for the exploding is that Trailmakers doesn't account for vehicle momentum when shooting the cannon. The cannon has an initial projectile speed of 120mph, so if the cannon is pointing in the opposite direction to motion, the bullet will collide with you when you go 120mph. In your second design, the cannons were tilted at about 45deg. Your new max speed is 120/cos(45), or ~170mph. The more perpendicular the cannons are to your vehicle's movement, the higher this limit. Edit: Smart idea by @bryanlandwehr7422 - "120/cos(81) ~761mph In theory, you could adjust the angle of the cannons based on the speed. Set them to 45deg as you start up, and slowly move them towards 82deg."
Since there are a lot of comments about the speed the cannons launch their balls vs vehicle speed I tried running the whole machine in reverse, thinking that the balls might accellerate away if it were traveling backwards. Nope, they close in just the same when the vehicle is traveling backwards.
With everyones answers about the canons projectile drag, implementing a delta wing or just a v shape with the canons mounted so they wont hit the colliders of the canons around them once you hit current max speed
you could put armor plates between the cannons since the armor plate counts as a full block. if they are as tight as they can the armor plate acts like theres no gaps between the cannons
Scrapman: "I gotta make the vehicle taller" Me screaming at my phone with futility: "just lower your rear wheels!!!!!!!" Also me after reading the comments "this is kind of hard to watch him suffer through this"
The cannons make you explode because you start traveling faster than the bullets so instead of the bullets moving they just fall like you are just dropping a ball.
The problem is that the cannonballs are being shot at a specific speed and then when you break that speed you move so fast that before they can move out the way they`re hit by the cannon and other things behind it.
Bullets probably come out at around 120mph in relation to the platform it's firing, and you going faster then the bullets come out probably results in a negative absolute velocity thus ending up in the cannon it was shot by before the craft received a momentum boost
Maybe if you had a big enough platform of down facing cannons on long stilts attached with detachable blocks set to turn the stilts to scrap, you could detach them so you are unsupported in the air and then fire the cannons and if you have enough the impulse of that single shot will momentarily make you break the sound barrier. As long as the stilts are high enough the explosion on the ground wouldn't affect you. Still this would be just a momentary shock wave, not a sustained speed over the speed of sound, so it's debatable if this would really count.
120 speed limit isnt a glitch. its how fast the cannon bullets go but vehicle speed boosts or slows gun projectiles down to about 0 when the projectiles come out they just blew up if you had them facing directly backwards. you turning the cannons made it so that they still had either no, or negative forwards bullet motion, but they still had sideways momentum that you didn't cancel out, so it pushed the speed limit to 70 where the sideways bullet motion no longer mattered.
I know that I am beating up a dead horse by saying it because the others are, but the problem is that a portion of the kinetic energy of the projectiles are inherent to the vehicle. if the cannons were facing forward and you went 120 MPH, the projectiles would go at 240 MPH. but if you are going 121 with the canons facing backwards, the projectiles are going TWARDS YOU at 1 MPH.
I know I'm a bit late, and you might not read this, but I have a cool trailmakers video idea: have the normal copmetition with the three of you, make a car that can drive the longest distance you can manage, no help with ski's or other parts, you can use pistons to help you off the ground initially though you could add your own restrictions aswell, and some other challenges. like driving as many circles as you can, or making jumps! PS: Keep up the good work, your videos always entertain me, and are what got me into Trailmakers myself!
If the problem is the cannons moving forwards, then the solution could be to put the cannons on a rotor to give them some backwards velocity at the moment when they are firing. This would solve the problem of having to put the cannons at an angle, but not their drag...
Honestly, I think you're idea would work in theory, but doesn't ONLY because of the explosions. I think what I'm seeing happen has to do with the way the cannons spawn the projectile. If you try putting a cannon on another vehicle that can break the sound barrier facing forward and fire it then, you might see the projectile work correctly? I am honestly not sure, but it seems the projectile wants to move the direction the vehicle is moving, and so, when you hit that term. velocity, the projectile catches up with the vehicle's velocity. I rarely play trailmakers though. I wish you luck figuring this out. Would be really neat to see it actually work.

bro its been so long since ive watched scrap man. like 2 years. im so happy he popped up
I was laughing so hard scrapman is confused by physics. Once you go the same velocity in the opposite direction of the bullet exit speed out of the barrel the bullet ground speed is 0 and fall straight down.
I think it is because you normally put the cannons on front but they shoot out at 120 so if you go that fast they collide with you, so the devs made it so that if you go higher than 120 it adds to the speed of the cannon projectile in the direction of your vehicle.
At least thats what i THINK.
6:00 Game dev here, most of the other comments are wrong regarding why you were hitting yourself. This happened in my own game. They are correcting the bullet speed deppending on your vehicle's speed, as to avoid shooting yourself when flying faster than your own bullets when they are fired forward. Somehow, they made it so that the frame you shoot the cannonball, it materializes inside or in front of the modules of your vehicle, making it detect the collision with yourself.
This is most likely because they are handling the input or cannons shooting in the Update() function of Unity monobehaviours which happens in every frame, and the cannonball is working in the FixedUpdate() because it uses a rigid body with physics, which happens at a different frame rate at fixed intervals. It can also happen between two separate game objects that work in the same update method and still have the issue of overcorrecting for the object's speed to avoid hitting yourself when you are flying and shooting forward.
Edit: if you want to make this easier, I would consider asking the developers to fix the self destruction issue to begin with.
This is following real world physics, just the cannonball explodes on contact, and it contacts the barrel of the cannon. ua-cam.com/video/BLuI118nhzc/v-deo.html This video by mythbusters showcases this effect
@@grimdagoblinmain This effect is correct, but it's not meant to register a collision with the vehicle itself. If something, it would still take about a second for the projectile to hit the ground since the vertical velocity starts as 0 and it's quite some distance from the ground.
I missed these series so much! :)
The explosions get closer and closer to the car as you get faster due to the 120 relative and you start going faster than that so unless you change the hit boxes or use a million glitches it’s impossible
im pretty sure the cannon projectiles are flipping around in the middle of their path because their velocity is either a) relative to the map or b) because they have actually have a net forward velocity (because youre moving faster than the cannon muzzle velocity) meaning theyre spawned in backwards and maybe since its the front of the projectile they connect and explode?
edit: hypothesis 2: Having seen the 180 limit at 14:20 i think its because the vehicle is slowing down just enough to collide with the cannons that dont have aerodynamics
the projectiles inherit the vehicle's speed. Their muzzle velocity is 120, so when you reach 120, you cancel out the projectile's velocity from the cannon and the projectiles instantly hit the cannons, blowing them up
Yay for Realism!I love when these things are in games to make them more realistic.
The cannon balls would never explode in contact with the cannon itself, the difference in speed between the cannonand the projectiles is always the same, they'd need to hit an external target.
It's just bad coding, nothing more
i've tried to strap every type of cannon on a rocket firing straight down, but every time the result was the blow up themselfs from tank cannon to tiny cannon way before the barrier.
And the dispensers don't really have much to begin with.
But hey, keep making the awesome content.
this is just the thing i needed ty
I think the game itself is reading the cannons as forwards facing; the game doesn't care about where the explosions are happening, it's just reading how fast the vehicle is going and calculating how far away teh projectile should be going from teh cannon, and it's set up so that higher speed means the cannon's projectile gets closer until you get blown up by the explosion.
The issue here can be tested by creating a engine powered vehicle with a canon facing backwards. Once the vehicle reaches 120 mph, fire the canon. If you blow up, then you know it's impossible.
everyone else has said it, but ima also say it cause why not: if the cannons fire at 120 kph, and your travelling at 0 kph, then the cannonballs get shot away at 120 kph. but if youre moving at 60 kph and you shoot a cannon, it gets shot out at 120 kph, but at only 60 kph relative to you. if you are then moving at 120 kph, and you shoot a cannon, the ball moves at 0 kph relative to you....and kills you. its a simple equality of velocities, but thats why its maxed out.
ps: i mainly know this because a mythbusters video 😉
the recoil movement is similar to the explosion thrusters where an explosive element would be launch behind a spacecraft and when it detonates the force would push the craft in the given direction... unfortunately as most of us know anything that involves explosives is 1. unreliable and 2. unpredictable attach such a device to a space craft costing billions and you've got a very dangerous and expensive firework... if you wish to create a vehicle that can travel at the rate of sound then i would suggest more conventional methods... but in the case of experimenting this is where sandbox games come in handy... as you can blow things up in a virtual world without the worry of accidentally destroying real objects
basically, once the cannon reaches a certain velocity (120 in this game(its like this in others similar too)) the cannon will fire, but the cannonball or projectile causes an error and seeing as it detects too fast for it, the game think you got shot
I think what happens is the faster you go the less accurate the canons get, so eventually they get so inaccurate that it somehow shoots sideways/ backwards
I did this once. I also glitched out the game with the exact same creation. Funnily enough, using only one rotating servo and a lot of cannons can do a lot to the game.
Maybe a sort of triangle with the back open, cannons facing backwards, on the inside and outside, should help with air resistance, deal with the exploding, and go fast
I have an MM idea. Trailmakers chase but the chasers weapons are your sticky mines and the fugitives is the explosive spike strip. Chasers use your vehicle's, fugitive builds their own vehicle.
Glad to see you doing these experimental videos again.
Look forward to the classic creative vids 😉
the problem on land is that the front wasn't heavy enough so then the cannon recoil tips it up which makes the whole thind do a wheelie causing the cannons to shoot closer to you as you speed up because of the increase of the angle
At the start when you made 4 cannons I was like “MAKE THE FRONT HEAVIER” due to the weight distribution being off by a lot.
honestly i have no idea what you guys are talking about but im loving it xd no but fr i used to watch scrape back in the day of when they used to play golf
This just hits home
I miss trailmakers
The fact that you could even take off with cannons is just crazy good job man
Would love to see a race or derby of this kind of concept. Might have been done before idk but would be really cool
As far as I can tell, the problem with the first vehicle is that the front was lifting up and tilting the cannons down ever so slightly, causing the shots to land closer
it seems like the bombs just explodes when their speed is 0. so as soon as you reach the speed the cannon ball is flying at they explode.
This challenge was unfortunately doomed from the start because cannons have a set shooting velocity and you either add to it by moving in the direction the cannon faces or take away from it by moving opposite. Having the cannons straight back means you equal out with the shoot velocity sooner and it just explodes on you, same thing for having them angle it just takes longer.
here is an idea to get more cannons:
at the spike connectors to the back and make a seperate part that has it on both, that will allow you to make infinite amounts of cannons
Looks like they add your velocity to the initial cannon velocity, causing the cannon to fire with near zero initial velocity.
Ah physics, with explosive rounds, about the same thing would happen in real life.
The reason the explosives are getting closer is because the front of the car is too light, it’s lifting up out of air resistance relative to the speed from the recoil of the cannons
The taw of inertia, the car is moving faster, but the cannon balls are moving at the same speed in the opposite direction, or something like that.
The reason you get hit by the explosions is because when you move faster the bullets go behind you fasten and when you hit a certain speed they can’t get out of the way of the other cannons in time
Scrapman: "Please dont kill yourself."
goin in the quotes text file
"This shouldn't happen" he says to something that absolutely should happen in real life physics.
What you need to do is time the cannons so they fire a different rate so the speed is continued through the shots. That might make the "car" faster and maybe not blow it up
Around 3:20 looks like an actual vehicle.
Someone built using a type of pulse jet “can’t remember the exact name”.
The way your car was built the faster you go the more you lift off the ground and since the front of your car was lifting off the ground, the cannons were shooting more twords the ground directly behind you
@4:26 I think it's a question of inertia. The explosions are propelling the car forward, however, they are also pitching the car's nose upwards, leading to the closer explosions.
So, it could be back heavy or not enough down force.
Yeah, and then @5:38 pitching them up is causing a rotational force pushing the nose even more upwards.
@16:16 are the projectiles being shot at a speed lower than the vehicle and then hitting themselves? Can you try without projectiles?
Nevermind, saved by the comment section:
DatBubby pointed this out:

As stated by others, the reason for the exploding is that Trailmakers doesn't account for vehicle momentum when shooting the cannon.
The cannon has an initial projectile speed of 120mph, so if the cannon is pointing in the opposite direction to motion, the bullet will collide with you when you go 120mph.
In your second design, the cannons were tilted at about 45deg.
Your new max speed is 120/cos(45), or ~170mph.
The more perpendicular the cannons are to your vehicle's movement, the higher this limit.
Edit:
Smart idea by @bryanlandwehr7422 -
"120/cos(81) ~761mph
In theory, you could adjust the angle of the cannons based on the speed. Set them to 45deg as you start up, and slowly move them towards 82deg."
Since there are a lot of comments about the speed the cannons launch their balls vs vehicle speed I tried running the whole machine in reverse, thinking that the balls might accellerate away if it were traveling backwards. Nope, they close in just the same when the vehicle is traveling backwards.
I demand a #Trailmakers Evolution Race using Cannons
With everyones answers about the canons projectile drag, implementing a delta wing or just a v shape with the canons mounted so they wont hit the colliders of the canons around them once you hit current max speed
you could put armor plates between the cannons since the armor plate counts as a full block. if they are as tight as they can the armor plate acts like theres no gaps between the cannons
Scrapman: "I gotta make the vehicle taller"
Me screaming at my phone with futility: "just lower your rear wheels!!!!!!!"
Also me after reading the comments "this is kind of hard to watch him suffer through this"
10:14 - I feel like this is something Dr. Bright would suggest
This is one of my favorite series you do lol
The cannons make you explode because you start traveling faster than the bullets so instead of the bullets moving they just fall like you are just dropping a ball.
You made me get both scrap mechanic and tailmakers and I don’t regret it
The problem is that the cannonballs are being shot at a specific speed and then when you break that speed you move so fast that before they can move out the way they`re hit by the cannon and other things behind it.
Bullets probably come out at around 120mph in relation to the platform it's firing, and you going faster then the bullets come out probably results in a negative absolute velocity thus ending up in the cannon it was shot by before the craft received a momentum boost
The legend is true
Trail makers will return
Maybe if you had a big enough platform of down facing cannons on long stilts attached with detachable blocks set to turn the stilts to scrap, you could detach them so you are unsupported in the air and then fire the cannons and if you have enough the impulse of that single shot will momentarily make you break the sound barrier. As long as the stilts are high enough the explosion on the ground wouldn't affect you. Still this would be just a momentary shock wave, not a sustained speed over the speed of sound, so it's debatable if this would really count.
scrapman pulled off the worlds most epic wheelie today
120 speed limit isnt a glitch. its how fast the cannon bullets go but vehicle speed boosts or slows gun projectiles down to about 0 when the projectiles come out they just blew up if you had them facing directly backwards. you turning the cannons made it so that they still had either no, or negative forwards bullet motion, but they still had sideways momentum that you didn't cancel out, so it pushed the speed limit to 70 where the sideways bullet motion no longer mattered.
Thanks for another Trail Makers Vid! I really enjoy them and was worried that you had switched to tear down until you beat the game
teardown is also great tho :)
I know that I am beating up a dead horse by saying it because the others are, but the problem is that a portion of the kinetic energy of the projectiles are inherent to the vehicle. if the cannons were facing forward and you went 120 MPH, the projectiles would go at 240 MPH. but if you are going 121 with the canons facing backwards, the projectiles are going TWARDS YOU at 1 MPH.
I know I'm a bit late, and you might not read this, but I have a cool trailmakers video idea:
have the normal copmetition with the three of you, make a car that can drive the longest distance you can manage, no help with ski's or other parts, you can use pistons to help you off the ground initially though
you could add your own restrictions aswell, and some other challenges. like driving as many circles as you can, or making jumps!
PS: Keep up the good work, your videos always entertain me, and are what got me into Trailmakers myself!
12:25 the spedometer forgot how to spedometer 💀
Finaly he figured out how a plane needs big wings
YESSS TRAILMAKERS AFTER ALL THESE YEARSSSSSSS
*reads title and puts hands together thoughtfully* you have my attention.
If the problem is the cannons moving forwards, then the solution could be to put the cannons on a rotor to give them some backwards velocity at the moment when they are firing.
This would solve the problem of having to put the cannons at an angle, but not their drag...
You travel faster the the projectiles, so they leave the Canon at the same speed as you move forward, and they fall down and explode
you're probably not going to see my comment but if you make the candidate slower when you go faster that's how you do
The silence between every explosion 😂
demoman approves
I haven’t seen this guy in SO LONG
Please keep uploading trailmakers i miss you playing it and racing with others
I think its that trailmakers calculates your speed to change the speed of the cannon balls but it doesn't work properly when backwards.
Honestly, I think you're idea would work in theory, but doesn't ONLY because of the explosions. I think what I'm seeing happen has to do with the way the cannons spawn the projectile. If you try putting a cannon on another vehicle that can break the sound barrier facing forward and fire it then, you might see the projectile work correctly? I am honestly not sure, but it seems the projectile wants to move the direction the vehicle is moving, and so, when you hit that term. velocity, the projectile catches up with the vehicle's velocity. I rarely play trailmakers though. I wish you luck figuring this out. Would be really neat to see it actually work.
Was thinking about you the other day and got recommended this
