pong power-up problem

Post subject:  pong power-up problem
My pong game is supposed to feature power-ups which at the moment only increase your paddle size. Unfortunately when the ball approaches often nothing happens and when the power-up does "activate" it's often when the ball is nowhere near the power-up. I'm sure I have just made a simple mistake in the collision detection but I can't seem to find the problem.

As well on the menu screen I have an option to quit the game, right now I am using the quit command as it was reccomended to me by a friend and I am wondering if there is a better command to terminate your program.

Thanks in advance

Turing:
if poweruponl = true then pl +=40   (Paddle length change left)

if poweruponr = true then pl2 +=40 (paddle length change right)




elsif x1 + RADIUS >= coord1 and y1 <= coord2 + 30 and y1 > coord2 and x1 - RADIUS >= coord1 + 30 and xChange =1 then poweruponr := true
       
elsif x1 + RADIUS >= coord1 and y1 <= coord2 + 30 and y1 > coord2 and x1 - RADIUS >= coord1 + 30 and xChange =-1 then poweruponl := true   


if anybody needs the whole code I can PM it to you, half of my class goes on this site Laughing

Is your pong with the paddles on the top and bottom, thus making the powerups shrinks and extend it left/right? Pop me the source and ill take a look, im kinda better at it when i see the problem firsthand.

Best way to open close turing windows is probably using the Windows Module. That way they completely close after the app finishes.

If your game is in a big loop, just exit the loop to finish the program by using "exit".
