How to ensure the player doesn't go off screen

[kurtss]

I'm currently making my first game, a Pong clone. How would I make sure that the paddle doesn't go off screen? I tried an if player.y < gameHeight - 80 (gameHeight is love.graphics.getHeight()) but then the player isn't movable.

Thanks in advance!

The "y" coordinate starts from 0 at the top and increases as we go down. I think your code should look something like this:

Code: Select all

if player.y < gameHeight - 80 then
 --movement down
else
--nothing, it's the limit
end

Code: Select all

if player.y > 80 then
 --movement up
else
--nothing, it's the limit
end

Tell us if it worked! Good luck!

Oh, wow! I didn't think of putting the up and down movements in seperate blocks. Thanks a ton!
