Never mind... play with the numbers long enough and you can find something that works....

Hi

If using wade.physics, I wouldn't try to do collisions yourself by getting overlapping objects. Instead, your falling object should be have a PhysicsObject behavior with body type set to dynamic, and the ground object should have a PhysicsObject behavior with body type set to static.

That answer didn't address the contact issue. No worries though, I took the hour and wrote my own physics engine to handle a platformer.  There were too many problems with characters turning upside down when they didn't hit a platform flush, etc. Now if half my player makes the jump he is put safetly and smoothly put on the platform.
