Thank you very much. I am very happy with the time and the teaching style.

This is an excellent video! This perfectly explains something I've been having trouble with!

Lovely video. Very helpful.

Excelent stuff here! I'm new to Pico8 and I'm really loving it. But guys, I really don't understand the reason people uses multiple multiplications like x*x*x instead of x ^ 3. Is there any reason?

where'd you go..?

for someone who is brand new to pico-8 you've done a great job explaining it and helping me get an understanding of the program. Great job.

Used your code for my single screen platformer game. Many Thanks 👍

Does anyone know if pico8 had any updates that make this code a little broken? I have the exact same code and the sprites with the same flags, but my character randomly changes direction even if I don't press any button, it looks like it "collides" with blank spaces on the map and then goes on a different axis. Here's the code: grid_x=0 grid_y=0 flag_tile=0 x=63 y=63 dx=0 dy=0 function _update() grid_x=flr(x/8) grid_y=flr(y/8) flag_tile=fget(mget(grid_x,grid_y),0) if btn(0) then dx=-1 end if btn(1) then dx=1 end if btn(2) then dy=-1 end if btn(3) then dy=1 end if hit(x+dx,y,7,7) then dx=0 end if hit(y+dy,x,7,7) then dy=0 end x+=dx y+=dy end function _draw() cls() map(0,0,0,0,16,16) spr(2,x,y) print(grid_x..","..grid_y,5,5,7) print(flag_tile,5,11) end function hit(x,y,w,h) collide=false for i=x,x+w,w do if fget(mget(i/8,y/8))>0 or fget(mget(i/8,(y+h)/8))>0 then collide=true end end return collide end

amazing tutorial

Hey uhhh doc robs how do u even make backgrounds?

Thanks a lot such amazing to learn that

you are like the khan academy of Pico-8 tutorials

question how would you use the S variable when you are using an SSPR sprites I'm working on a thing in class so I don't have any audio

Please write a book!

I hope you make more of these too ! Thank you!

always makes me move without stopping and when i collide, i cant move at all to any direction that doesnt have a wall

Great vid! I have one question, how do you make it for the up and down animations. I tried to make it with the same code just different animations, it didn’t work. Could you please help:)

Thank you so much for this video! I deeply appreciate you explaining how to round it to an integer, this is exactly what I was looking for!

Well I got to 2mins 20 before being utterly out of my depth. Was worth a look though but jeez I wish pico-8 had a built-in collision command (like detectSpriteCollision(sprite1, sprite2) and it returned true if there was a collision.) as it stands now, pico-8 is fun but collision is an utter nightmate and might be the one thing that stops me from making games in this. a pity

Could someone explain what the `i` variable is for in the `for` loop? My code works, but I didn't catch him explaining it in the video.

does anyone know how to make the loop longer? can I use the whole span of the x-axis of the map to create a longer loop? how do I do that in the code?

thank you so much, you helped me a lot, thanks for taking your time to record such a great tutorial. awesome radio voice and audio btw

perfect ..thank you!! exactly what i needed=)

These are excellent videos!

super cool, made it seem simple and now I understand how not to change every color but only the one sprite I need

Random numbers were such a headache in NES games. Pseudorandom numbers are often calculated as a bit shifting and reordering operation, but you need to be extremely careful to use an operation that doesn't have any predictable results. Imagine if your random number generator always returned 4, then 6, then 1, 4, 6, 1, 4, 6, 1. That could be a disaster, if you want it to be unpredictable, or to produce every possible value. The original Final Fantasy hardcoded a list of a few hundred predetermined numbers, and calling the equivalent of rnd() just looked up the next value in that table; that was the most reliable solution the programmer came up with. PICO8 being emulated allows it to pull unpredictable values from the host system, so rnd() is incredibly easy and incredibly reliable.

one question: What is the game you showed first? Could you tell me?

My brain gave up immediately

Hey Doc, thank you for all your tutorials. You have a very clear and calm way of explaining things, please don’t give up on making these excellent Pico-8 tutorials! We are sorely lacking in excellent video tutorials for this wonderful software!

Please continue this, I found you while looking for background scrolling and find your videos very useful. Thanks a ton

Anyone know why mines saying self is a nil value?

Could you use btnp to space out the bullets?

Thank you so much for your videos Doc! You've helped me so much in my game dev journey!

Sooo good!!!

Searched UA-cam to learn how to do this. This explained it perfectly. Thank you.

I really appriciate this video! I fixed my problem in a few moments.

Amazing tutorial, as always. I was coming into this thinking I'd know everything already, but I was entirely unprepared for being able to put FUNCTIONS into objects. Not that I'm an expert, but I had read the documentation and, as far as I could tell, it makes no mention of this function-ality (ha). I'm going to have to revamp a couple of my projects to use this knowledge now.

The fget doesnt work when i print it, it always says 0

Instead of adding values one by one all the time, you can check if the x+SPEED value is not going to collide and add the whole speed otherwise you add values one by one until you reach the collision point. Great tutorial!

Quick Question, what if i wanted to make a space shooter, and my ship is trying to move in a way where if i go right it goes to one sprite change of it turning left or right.

thank you so much for this this has help me make so many games.

I stopped being able to move as you did x y and d y

my map is larger than 127x127, i wanted to make my character stop when on the edge of the camera, but its stoping on the edge of the map tile please help

Hello is it possible to have the game cartridge? thanks

are you going to continue this

@doc_robs thank you for the wonderful tutorial series! However, I do have a question regarding collision. I have followed both this tutorial and the fget mget collision tutorial. I have attempted to combine the two but when I try to return the X, Y, W, H to the collision i am receiving runtime error at IF HIT(X+DX,Y,W,H) THEN. "ATTEMPT TO PERFORM ARITHMETIC ON GLOBAL 'X' (A NIL VALUE)". Is this because the object BULLET has no way to index values? Any help would be greatly appreciated. Cheers!

As I continue to learn PICO-8, I always come back to your videos as the best tutorials with the best explanations, and no time wasted. Thanks again!

Wow! I've been trying to do this!

This video isn’t very good you leave multiple things un explained

hey mate, loved all your videos. sad to see they seem to have ended, but i appreciate that you made them in the first place! Would love to see how you make a functioning game with different tabs for the init, update, draw!
