1 vs 200 MC:
this one uses Array()

plain hitTest()

copy/paste


stats:
=======
800MHz, 128 Mb RAM:

1) collision with array()- 1 against 3000 :
- actuall frame rate 35-40 / movie set to 50 fps

2) collision with hitTest()- 1 against 1500
- actuall frame rate 2-3 / movie set to 50fps

400MHz, 32 Mb RAM

1) collision with array()- 1 against 1000 :
- actuall frame rate 35-40 / movie set to 50 fps

2) collision with hitTest()- 1 against 300
- actuall frame rate 2-3 / movie set to 50fps

the collision is not very tight some optimization needed.

How it works:

the scene is split in sqrs 50:50. 200MC are placed at random. _x and _y converted to sqr coordinates. 2D array wich holds sqr_number plus the names of the clips in that sqr. Collision is done only in one sqr at a time between 1-5 hitTest().
