Sorry for the probably stupid question, but I've just started and decided to first try my hand at making a pong game from scratch (no pun intended). I have mostly everything down, but I want to make it so the background switches if you hit an object that appears in the middle of the screen after 30 seconds. The if -> touching (ball) only counts if it is continuously touching the object. I want it so it only needs to hit the object to change the background, i.e. the ball only has to travel through the object.

Thanks.

You could use something like

Hide
wait (30) seconds
show
wait until (touching (ball))
broadcast (next background)

You can put this script in a forever block if you want to.

If I understand correctly, you have a sprite in the middle, and you want the background to change when the ball hits it? Then just have this on the sprite:

Code:

When green flag clicked
repeat until < game over >
    if touching [ball]
        broadcast [switch]
        wait until <not <touching ball> >
    EndIf
EndRepeat

And on the stage...

Code:

When I receive [switch]
next background

Hope that helps! big_smile

P.S. <game over> is whatever condition(s) triggers a game over. (or a game over variable)

Use if touching, but put a 'Wait until [not <touching [object]>>]
