Great video! i had to pause several times because while I was brainlessly following other tutorials, you explained what specific lines of code did and everything just clicked, thank you!!
Been working on procedural animation recently and needed to look into raycasting. This is the best tutorial ive seen for any topic in roblox studio by far. Thank you and i hope you post more! I typically never comment but this was amazing
This is such a good raycasting tutorial!!!!! I could 100% see a new roblox scripter easily learning how raycasting works with this video. Great job using animations to explain how raycasting works!
how is this so underrated yet the edit is absolutely amazing and the teaching finally actually teached me the most of raycasting, you deserve a million subs dude
Well I don't speak English very well, so I'm screwed, but finally a young person who knows how to make tutorials! This way of learning, here is a real tutorial and not just a presentation of a script
While the video does great at explaining how raycasts work... the main raycasting of the gun is all happening on the client, which doesn't really work well in a multiplayer environment.
It doesn’t, you’re right. But for games with small servers or small Raycasts / second, it’s totally fine. In my experience, even 20-40 Raycasts per second works fine
I wish I've find you sooner your video is very helpful and made with efforts! I've been struggling trying to learn raycasting for a while and this video help me out a lot you deserve more subscriber 💖
this is good good job and also can you make more vids on advanced stuff? pls like stuff that isnt taught yet bc most ppl say read the docs but i like hearing than reading
This is one of the best tutorials on ray casting I have came across on UA-cam (along with ByteBlox’s)! I am looking forward to more uploads from you :)
This is actually the best explanation, but these are extremely hard to make so i ront expect a full scripting tutorial with these types of explanation and jokes lmfao
Yup. It’s used everywhere, especially in places where we would never even think of. When a gun is firing, we fire a ray where the origin is the gun and the direction is where our mouse points (just like in the video) When you select a troop in a tower defense game (or in my game, battle mania), a Raycast is done from the foot to the ground so the script knows where the ground is and to place the troop effectively
I was talking specifically about the "Normal" of the raycast. I know raycasts are used for basically everything, super useful tool. But before now I had no clue what the normal of a raycast instance was, and during the video I was wondering when anyone would ever use it.@@scripting
@@AntiNuke_ Gotcha. Yeah, the normal is used like in the footsteps example, and perhaps also making a thrown object ricochet off surfaces it hits. For example, a ball is thrown. It hits a wall. Apply a lesser force on that ball with the direction of the normal of the surface. Repeat. If you do this to a laser, it can give a laser bouncing off / ricochet effect
Yep, I just actually used the normal of an object to make a script that makes the camera bounce off an object it hits using a raycast from the head to the camera position detecting what the camera is hitting.@@scripting
Very good tutorial. The only thing i need to know now is how people make it so when you shoot a gun with raycasting. It will leave a trail so it looks like it is a kind of bullet, a lot of games have this :D
You could, but this video was made before I found that property out. Behind the scenes however, roblox most likely uses Raycasting to deduce the floor material
Gave up on this tutorial 6 minutes in. The added graphics got in the way of seeing the script. Script was added without it being noted in audio. Couldn’t get past an error when trying to get the mouse position in the Handle script.
so sorry if im bring stupid here--at 5:20, where exactly do you put the localscript? StarterPlayer, ReplicatedStorage, or whatever? I'm unsure where it's supposed to be
I have a question, how much did you Need to study(practice) scripting and other game aspecpts before being sure to make a big project like the ‘Battle Mania’. I am asking this because i currently have about 1year scripting knowledge, and i don’t really know to build on blender, make Vfxs and that stuff😅
I’ve been scripting for 8 years. So, by the time I began battle mania, I already knew how to script anything I wanted lol. Keep on scripting though, script whatever you want to script and whatever is interesting, and you’ll get there.
6:38 when i ran it i got an error "Players:GetNameFromUserIdAsync() failed: HTTP 429 (Too Many Requests)" anyone know the issue? this is the code local laser = script.Parent local getMouseRemote = game.ReplicatedStorage.getMouseRemote laser.Activated:Connect(function() local player = game.Players:WaitForChild(laser.Parent.Name) local rayorigin = laser.Handle.Rayorigin.Position local mouseposition = getMouseRemote:InvokeClient(player) local raydirection = (mouseposition - rayorigin).Unit * 400 local raycastresult = workspace:Raycast(rayorigin, raydirection) if raycastresult then print(raycastresult.Instance) raycastresult.Instance:Destroy() end end)
@@corbinwalton9996 I know how to do that, but I wanted to use raycast to make projectiles instead and if it would touch the character I would now lower the health.
also while making a raycast i noticed it said that the ray cast params had to be included in the raycast result when i tried doing it how u did it, it failed to work but when i added the params above the result and into the result it worked, so uh just wanted to ask why it worked for u but not me? : edit nvm my brain farted
if anyone has any idea if this works, is there a way to make it so that I can have the ray fire off when I press space bar as oppose to having a weapon active? thanks! I should also mention I want the ray to originate from the Player
So that’s because it shouldn’t be OnClickInvoke, it should be OnClientInvoke The reason it doesn’t give you an error when it’s in server script service is because local scripts cannot run there

Highlight the area of your script you want to de-indent. Then press control + [ Doing that will de-indent those lines. Pressing control + [ will apply an indent to those lines. You’re welcome
Yes you can. The way it’s done is like this: fire a Raycast. From the Position of the Raycast Result, fire another one again in the same direction. And another. … and so on
Raycasts only give you the first thing. Imagine a really slim needle that only touches one spot. That’s kind of what the “laser”is. To get everything, you can use region3. Basically, you create a region around the thing the ray touches and get everything in that region.

hold on, at 7:34 ish, doesnt the roblox humanoid have a floormaterial property? couldnt you use that instead??

Most definitely
The top of my left eye enjoyed the first half
Best Raycasting guide out rn
You know it 💯
followed the code and at the point around 5:30 instead of the raycast returning the values it returns nil
I believe it’s because for the Attachment.Position, it should have been Attachment.WorldPosition
SO UNDERRATED
You are extremely underrated
6:38 when i ran it i got an error
"Players:GetNameFromUserIdAsync() failed: HTTP 429 (Too Many Requests)"
anyone know the issue? this is the code
local laser = script.Parent
local getMouseRemote = game.ReplicatedStorage.getMouseRemote
laser.Activated:Connect(function()
local player = game.Players:WaitForChild(laser.Parent.Name)
local rayorigin = laser.Handle.Rayorigin.Position
local mouseposition = getMouseRemote:InvokeClient(player)
local raydirection = (mouseposition - rayorigin).Unit * 400
local raycastresult = workspace:Raycast(rayorigin, raydirection)
if raycastresult then
print(raycastresult.Instance)
raycastresult.Instance:Destroy()
end
end)
also i tried to make a visulizer for the raycast(to help me do it easier) and then it was floating so idk whats that about
So how do you make a gun with projectiles with raycast?
check if what it hits is a player by checking if its parent has a humanoid and then lower the humanoids health if there is one
@@corbinwalton9996 I know how to do that, but I wanted to use raycast to make projectiles instead and if it would touch the character I would now lower the health.
5:26 bro didnt cooked with this idea
Why does it say “ray origin” is not a valid member of part?
okay what was that shortcut at 20:09
I swear I'm always learning new studio shortcuts that save me hours
ctrl + [ or ]
this video explained raycasting very well. although why did you give it to ur little brother again?
Thanks. The reason we gave it to the little brother is because it isn’t dangerous. It’s a toy! 😅
is there a way to make the raycast like into a visible object like a laser or a bullet
You can. You’d make a part and set the CFrame to look where you want it to and the size.Z (or size.X) to the raycastResult.Distance
finally a good explain video for idiots like me
I fully think that if you’re watching this video, you are not an idiot
also while making a raycast i noticed it said that the ray cast params had to be included in the raycast result when i tried doing it how u did it, it failed to work but when i added the params above the result and into the result it worked, so uh just wanted to ask why it worked for u but not me? : edit nvm my brain farted
9:17 THE HARDEST CUBE EDIT I HAVE EVER SEEN🔥🔥🔥🔥🥶🥶
Is this inspired by Cary time traveler video.. 😱
Nope
@@scripting Oh, because I thought of the baby reference.. they used. 🤔
@PurpleLegoPieces the baby picture was one I found from unsplash, a free stock image site
if anyone has any idea if this works, is there a way to make it so that I can have the ray fire off when I press space bar as oppose to having a weapon active? thanks!
I should also mention I want the ray to originate from the Player
time to take the script and redo it without learning anything-
Where do you create the mousepos script at 5:20?
I believe it’s a local script in starter gui
@@scripting when I put it there is says
OnClickInvoke is not a valid member of RemoteFunction "ReplicatedStorage.GetMousePosition"
when I put it anywhere besides ServerScriptService it gives me an error but even when its there it doesnt work
So that’s because it shouldn’t be OnClickInvoke, it should be OnClientInvoke
The reason it doesn’t give you an error when it’s in server script service is because local scripts cannot run there

How do u remove the indents if u end up removing an "if" statement, its always so annoying to have to remove them.
Highlight the area of your script you want to de-indent. Then press control + [
Doing that will de-indent those lines. Pressing control + [ will apply an indent to those lines.
You’re welcome
@ thank you my brain dies when it looks odd like that after so this is very helpful
Is it possible to make the raycast go through everything? Or i have to use somrthing else
Yes you can. The way it’s done is like this: fire a Raycast. From the Position of the Raycast Result, fire another one again in the same direction. And another. … and so on
@@scriptingthanks
isn't the a humanoid property called floor material?
bro what did the monkeys do to you😭
Uh, guys i think u guys got an error, and it isnt working now, to fix that, i did so the rayoriigin is the worldposition instead of position.
Yes, that was fixed later in the video
is it impossible to get all the things the ray is touching?
Raycasts only give you the first thing. Imagine a really slim needle that only touches one spot. That’s kind of what the “laser”is. To get everything, you can use region3. Basically, you create a region around the thing the ray touches and get everything in that region.
