MemPointDirectionalCheck()

static bool MemPointDirectionalCheck ( PlayerBase player, EntityAI targetEnt, string memPointStartName, string memPointEndName, float toleranceAngle = Math.PI_HALF )

staticprotected

Returns true when the player stands on the opposite side of memPointEndName relative to memPointStartName (angle exceeds toleranceAngle) Intentionally returns true (no restriction) when the check cannot be performed (missing player/entity or memory points) Callers where a failed check must deny access have to verify the preconditions (e.g. MemoryPointExists) themselves
