How do I attach to dynamic image point?

I would like to "stick" two sprite objects together at the point that they collide using a dynamically created image point on the collided object and pinning the colliding object to it at that point. Is this possible?

Sorry, my bad. By "dynamic image point" I mean that a new image point is created at the point of contact.

You can't create image points. At least not with conventional methods, maybe there is an addon for that. You can just use a pair of instance variables to store that "virtual image point" coordinates.

Detecting the exact point of collision is another issue. I have a demo, but it's quite complex.

If you explain why you need all this, maybe we could suggest another solution.
