"land_radius"  The distance of the ground the piece\
               should be when on the ground ( default 0 )

"key"          The item needed to activate this. (default nothing)

IF RANDOMANGLES is set, object randomly spins while in the air.
IF LANDSHATTER is set, object shatters when it hits the ground.
IF TWOSTAGE is set, object can be shattered once it lands on the ground.
IF ACCUMALATIVE is set, damage is accumlative not threshold
IF INVISIBLE is set, these are invisible and not solid until triggered
If NOT_PLAYERS is set, the trigger does not respond to players
If MONSTERS is set, the trigger will respond to monsters
If PROJECTILES is set, the trigger will respond to projectiles (rockets, grenades, etc.)
