A_SplitShot

A_SplitShot is an action that shoots two missiles aimed towards each side of the actor's target, one directed left and one directed right. Var1 determines the horizontal offset from the target's position to aim for; the offset is added to one missile and subtracted from the other. Var2's lower 16 bits determine the Object type of the missile that is shot. Var2's upper 16 bits determine the height offset the missiles are shot from.

This action originates from the v2.0 modification SRB2Morphed and was added to SRB2 itself in v2.1.
