I had been thinking of setting up my own missile defense animation and see
how hard it was!

I was about to give longer advice here , but I got confused by the concept
of a laser "querying its host object".

You can set up a system where you have eight variables defining your "flying
duck".

Position    (3 variables xyz, affected by velocity)
Velocity    (3 variables xyz, affected by gravity, willful acceleration)
DeadYet     (0=alive; 1=dead)
TimeoDeath  (Number of time frames SINCE I've been shot.  )


#if(DeadYet>0.5)
    #declare TimeoDeath=TimeoDeath+1;
#else
    #if(vlength (Postion-Bulletposition)<ContactDistance)  // ala Bob H
        #declare DeadYet=1;
    #end
#end

Then display duck, duck fragments, etc., based on above variables.
