FlxQuadTree usage example

  • Hi all,

    Could anyone point to or provide an example of usage of FlxQuadTree? I could not find any so far.

    It's used internally for FlxG.overlap() / FlxG.collide(), and not typically used directly.

    What are you trying to do?

  • I thought it would help implement an efficient collision detection... I have entities located in a rectangular cell in the world, and I need to check whether the player is in the same cell of one of them (and need to know which one).

    EDIT: thanks for pointing out it's an internal class.

  • Yes, as Gama11 said, FlxG.overlap() already does that for you, it uses FlxQuadTree for more efficient collision detection.
