preventing collision behavior but still fire collision event

Games
#1

I notice that the collision event does not fire unless I set a property like “density” or some other property. Once I set density =0.1 I get collision events but I do not want the objects that are hitting each other to effect the other objects velocity at all. How do I do this.

thanks,

NM I found the documentation to help with this.
