How do people implement hunting?

[Kayaker Magic]

    My understanding of physical bullets is that in a collision, only the physical object gets notification. I don't want my target critters to have to be physical, so only the bullet gets notification. So how does the bullet tell the target that it has been hit?

    llCastRay sounds like a better way to do this than physical bullets. Again, it is the “gun” that casts the ray and figures out that it has “hit” some other object. How does the gun tell the target that it has been hit?

    I assume that some sort of message is sent and susceptible targets listen for it and react accordingly. Is there a standard protocol for this? Does everyone use the same channel number and message format? Or am I assuming a level of co-operation between weapons makers that doesn't exist in the wonderful collaborative world of Second Life?

Your understanding is mistaken, I think.  I've just dropped a physical prim onto a non-physical one, and the non-physics object said "ouch" in the collision_start event.

ETA  -- it has to be that way, if you think about it, otherwise welcome mats and suchlike wouldn't work.
