2 things I want from collision :


1 : How do I tell my program to stop the object from moving when it hits a wall, so far I got this =

IF OBJECT HIT(1, 2) THEN ...

2 : How do I tell my program to move the object in the opposite direction when it hits a wall, same code as above.

Cheers,

Daz

well, you just dont move the object when it hits a wall. simple. this would work instead of using 'move object':

IF OBJECT HIT(1, 2)=0 THEN MOVE OBJECT 1,1

then when the 2 objects touch the first one wont move anymore. Honestly, you should ask me for help if you need it!

oops, this is the correct code:

IF OBJECT COLLISION(1, 2)=0 THEN MOVE OBJECT 1,1
but I think both should work depending on what you want. the 'COLLISION' is the best one

Okay, there should be easier commands than using coordinates, as I've just look through some of the new tutorials. When I say opposite direction I mean like a rubber ball bouncing off walls. How do I get that effect? Like a "mirror" effect. Where it bounces at the same angle. Say it bounced at an angle of 45 degrees. It would bounce 45 degrees the other way. Get me?

I need this for my game for the compo. I need to do a background, collison for paddles and a ball bouncing how I want it to. Then I'm done and I can add little features like trails and a ball that appears to be bouncing.

All before April 7th, eek!
