Hi! I am making a game with ships shooting lasers and I ran into a problem. The xLimit and yLimit values are what I think are causing the problem, but I can't figure out how. The ships, when they start, only go down, until they reach like halfway down, and then can go up and down but only up halfway. They can also go lower then the screen, and that is a problem. Just test it to see what I mean, k?

NPaintPro sprites: http://pastebin.com/YMfvLfwz They need to be named what is in the brackets next to Ship, Ship2, and Laser.

Game: http://pastebin.com/brbUAS1E

Thanks in advance for your help!

Oh ya, I forgot to say i didn't implement shooting yet, so thats not the issue.

Edit: Now that's 2 ask a pro questions that everyone has abandoned...

2 things.
1. instead of comparing key to keys.up and keys.w seperately, you can do that in one sentence (if key == keys.up or key == keys.w then)
2. to solve the problem you could do something like this

 local w,h = term.getSize()
--then add the following after the ship has moved
if ship.y > h then ship.y = h end 

that should move the ship back to the bottom of the screen if it tries to go out of it.

That does not answer my question. Have you RAN the game? It SHOULD just go up and down through the screen, but it seems like it is offset.

Can anybody help me? I am trying to make this a long-term project, but this is a fatal error.

Edit: I know I know, Y_U_SO_IMPATIENT, but I really want this fixeeedddddd..... XP

No I was unable to run your program when I earlier responded. I thought you said the problem was that the ship could go lower than the screen.
If nobody has helped you in a couple of hours, I'll take the time to run the game and see what the problem is exactly.

Im not sure what the problem is.. Both ships are moving up and down perfectly fine for me

[MudkipTheEpic]

Can you move up to the top of the screen?

Yah, that is the problem. I want it not to be able to go if it goes below the screen.

Edit: It seems to go 31 blocks below the screen.... o_O

Edit edit: IT WORKS! Just set yLimit=ySize-36 to work!

here is your problem:

local ySize, xSize= term.getSize()

term.getSize() returns width,height. not height,width
