How do I move a sprite half way across the screen only?

I'm trying to make a 2 player Pong type game but rather than having just up/down direcions..I have 4 directions.....my problem is trying to find a way to control the distance of the left/right movement. I don't want my players to move any than the center of the screen whether the player is on the left or the right side of screen.

if player1 X coordinates > than window width/2 then set player1 X to window width/2

same goes for player2 if X coordinates < window width/2 then set player2 x window width/2

Hope this helps .. Easiest way i came up with .... Im sure there is a more precise way to do it but that just came off the top of my head and was real simple

Oh, was too late - same idea, but I also have a second solutions so I post it anyway

I'm not sure if I understand you correctly

Do you mean you don't want player1 to cross to the other side?

If yes, I have two solutions

You can make an invisible border with a sprite block that can't be crossed. Or make a custom key movement for your player and give him a second condition (the following example subtracts half of the player x size - in this case 16 if the origin point is centered)

If pressed right

and

Player position.x <= windowwidth/2 - 16

thank you both for your replies...ill try them out.. I did try putting an invisible sprite in the center of the screen but I gave it a solid behaviour and that made the players stop but the Ball bounced off of it and just stayed on 1 half of screen

I would do something like this:

system every tick

• player1 set x = clamp(player.x,viewportleft(0), viewportleft(0)+0.5*(viewportright(0)-viewportleft(0))
• player2 set x = clamp(player.x, viewportright()-0.5*(viewportright(0)-viewportleft(0)), viewportright(0))

thanks LittleStain, that's done the trick

fr0z3n, your suggestion worked for my player 1 , it moved bout 3/4 way across its side of the screen but for player 2 , it moved past the center of screen and stopped equal with player 1s furthest point.

thanks again everyone for taking the time and your help
