Well im making a pong game, im trying not to use the tutorials too much, but when it came to limiting movement I had to look. I tried changing the "z" value to something like p1pos# , and then in the if upkey()=1 and p1pos#>-10: move sprite 1,10 ...something like that, but it doesn't want to work for me =\ Can anyone help?

One other question, how can i set my background in the main menu back to the original, because ever since i loaded the paddle it changed to a picture of the paddle.

Thanks in advance.

Media is attached..

well, there's no reason your method of limiting the z movement of the paddles shouldn't work, if done correctly; a check within the if statement is appropriate:

+ Code Snippet

...

minz# = -11.0
maxz# = 11.0

...

if upkey() = 1 and object position z(11) < maxz#
   move object 11, 0.5
endif

...

you didn't show this functionality attempted in the code provided, so we can't know what you might have done wrong.

and,

make sure you use the correct parameters for commands. ie, if you're using 3D coordinates, make sure you use floats.
your player 1 controls should be (assuming you still want it to move twice as fast as player 2...):

MOVE OBJECT 10,1.0
...
MOVE OBJECT 10,-1.0

plus,

i dunno where you got the...

Quote: "move sprite 1,10"

part mentioned in your post, unless that was a typo, but you've got no sprites in your app. just making sure you realize that.

as far as the background changing, as soon as you load the paddle model, it's gonna show it. look at using hide object when you're at the menu screen, then show object when in "play" mode.

by the way, your controls seem upside down. ie, W and UpKey should move their paddles up, S & DownKey = down. but, it's your game, so...

try the suggestions offered and come back if you're still having trouble. good luck!

Alright, thanks a lot..
Yeah alot of this was when i was experimenting with all of the move speeds and stuff. I still had a lot of typos, and i i forgot to save the updated version.

Thanks again =)
