[as2] Complex Collision Detection

[marcelozep]

Hello.
I wonder, if there´s a way to do a collision detection for irregular shapes (complex shapes).
I know about the g skiner´s class, and I can´t use it, because it needs to put the author´s comments.
So, there´s another way, free to use?

Thank you.

I think what you're looking for is Box2D (http://box2dflash.sourceforge.net/). It is however written in AS3.

Yes, something like this but with really irregular shapes, I mean, shapes with curves.
Thank you ;).

You can try the the AS3.0 Collision Detection Kit

I've haven't used it before but it might be worth looking into.

i really don't know anything for AS2 about collision
(you can always write your own of course)

here's a good one for AS3 http://www.cove.org/ape/

Is this about hitTesting or physics engines??
If its about hitTesting you could use bitmapData.hitTest() if you have flash8 or later.
You could also try to set shapeFlag to true:


public hitTest(x, y, shapeFlag) : Boolean
public hitTest(target) : Boolean

x: Number The x coordinate of the hit area on the Stage.

y: Number The y coordinate of the hit area on the Stage. The x and y coordinates are defined in the global coordinate space.

shapeFlag: Boolean A Boolean value specifying whether to evaluate the entire shape of the specified instance (true), or just the bounding box (false). This parameter can be specified only if the hit area is identified by using x and y coordinate parameters.

And here we go thinking about advanced collision engines when we hear the keyword "irregular shape". That is actually a pretty good solution flashmxboy.
