How do I Detect if teh Center of my object

Hey guys

How can I detect if the center point of my playeobj is overlappng with a wall/object.

The reason is I allow a little overlap of the player object to walls to cause damage but if the center of the player overlaps the wall i trigger death.

thanks

I am sure one of the math guys can give you a formula.. however, I can think of two other ways:

1. Put an imagepoint in center (created in sprite manager) and use it to test overlap.

2. Pin a small sprite to center on creation and use this sprite's on-overlap condition to kill player (you can easily adjust size and shape of "kill zone" this way).
