Collision Issue Solved

This is a noobie mistake, but it may help someone. My collisions with objects were becoming way off center. I wasn't sure how to fix it. After about 10 minutes I figured out it was the Z Elevation setting on the object.

I changed the Z Elevation back to 0 and that fixed everything. It looks like the Z Elevation setting simulates the object being closer or further away from the camera.

Note this is documented in the manual as part of the Set Z elevation action:

Z elevation only affects the appearance of the object. It does not affect collisions - everything else continues to work in 2D as if its Z elevation was still 0.
