Detailed Description

A specialized kind of CollisionHandler that simply pushes back on things that attempt to move into solid walls.

This is the simplest kind of "real-world" collisions you can have.

bool CollisionHandlerPusher::handle_entries ( ) [protected, virtual]

Called by the parent class after all collisions have been detected, this manages the various collisions and moves around the nodes as necessary.

The return value is normally true, but it may be false to indicate the CollisionTraverser should disable this handler from being called in the future.
