Hello Blender devs, I'm getting tired of not having access to collision information from the BGE Python API, so I've decided to address this. I'm thinking a collision would generate two collision events: one relative to each object. This CollisionEvent object can contain information like hit location, hit material and hit object (the material and object would be what the object is hitting, remember, the events are relative to an object).
However, I'm uncertain as to how the user should access this events. Other events like keyboard and mouse events are done by checking some sort of list. If I were to do this for collision events, I'd keep a list of collision events on each KX_GameObject. Making use of this list would look something like this: for ce in obj.collisions: if ce.name == "Bomb": obj.endObject() This looks good and is consistent with the rest of Blender. However, I'm wondering if callbacks might be better? A callback example would look something like: def col_bomb(self, ce): if ce.object.name == "Bomb": self.endObject() obj.register(col_bomb) The callback example only has to be run once where as the list example must be run constantly. I've put some of these ideas in a brief wiki page[1]. Thoughts?
