[QUOTE=Ashley] Can you post a .capx showing the problem?
The problem with small objects, especially at low framerates, is often they can simply step entirely past a barrier. For example an object travelling at 600 pixels/sec at 30 fps is travelling 20 px per frame. If it is only 5x5, it's actually "teleporting" in steps 4 times bigger than itself every frame, and this means it could entirely jump over another 5x5 object without registering a collision.
However, this is no reason for objects to be floating above other objects, so a .capx would be useful.[/QUOTE]
I might just be talking out of my ass here but what about using loops for pixel-perfect or instant-hit bullets? Could something similar be applied for the platform behavior's collision detection?Here's
an example I whipped up.Tokinsom2012-04-16 04:02:27
