A7 Gamestudio Pro, version7.8
Hi, when I declare the event

my.emask |= (ENABLE_IMPACT);

In the action of an entity, the normals obtained from this entity when hitted by another are inverted. Only with this event declared, all of the others work correctly, with the normal vector pointing perpendicularly away from the surface.

Sorry for the inconvenience if it was already found, but I didnt find anything on the forums regarding the issue.

Thanks.

I don't think that the normal is inverted, but I can guess a possible reason of the problem: The normal is always taken from the hit surface. That's from the entity itself, not from the other entity, and this is different to the other collision events.
