Pixel-Perfect Collision Detection

[Nicolas Gramlich]

Hello Community,

you might have already experienced that in (from today) old versions of AndEngine the CollisionDetection sucked big time - rotation and scaling of the objects was simply ignored.

Yesterday and today I was on the 'Pixel Perfect' Collision Detection in AndEngine.

Not bad hm

I also added an Example:

So don't forget to grab the latest andengine.jar from the repository to get in touch with this cool stuff .

Best Regards,
Nicolas

Nice, works great

Hm, from the source it seems that it's not pixel perfect collision detection but rather polygon intersection testing. Any planes on adding ppc for pixel masks?

*fail*

Doing a deeper Google-Search I have to admit the naming I chose sucks.

Currently I don't have plans on adding real >Pixel-Perfect< Collision Detection.

No biggie, it's still a nice implementation. Consider using some spatial partitioning scheme for huge scenes and maybe port the polygon intersection code over to C, it could really benefit from that.
