Collision Detection

Hi, if I have 2 bouncing squares, bouncing around inside a larger square how do I detect when the squares hit each other? I can get some level of detection using an IF on the top and left properties of the objects but not the whole square can anyone help? I hope this makes sense!

What do you mean 'some level of detection'? You will also need to check if the other sides of the squares have collided, assuming the squares can get past each other that is, but what's wrong with what you've got so far?

Shouldn't be hard

Code:

---

a=x1t<x2t'top borders
b=x1b>x2b'bottom borders
c=x1l<x2l'left borders
d=x1r>x2r'right borders
if not((a xor b) or (c xor d) or (a xor c)) then 'collision

---

Thanks Guys!
