Thrower0123OnRez
This value is set inside the REZZABLE.
This value should be 1, 2, or 3 for situations where you are creating a Thrower-Rezzer. The number determines which selection of ApplyImpulse, AngularVelocity, and CollisionPostActions will be used.
It should be zero (0) if you are rezzing a normal Palette with NO throwing capabilities.
Ex:
Thrower0123OnRez,1
The zero (0) option uses the current position and rotation of the rezzer. i.e. no throwing of the Palette is used with this option.
The initial velocity of this option is always the same as the rezzer with is usually zero, so it rezzes static, non-moving, unlike 1,2, and 3.
