UKismetAnimationLibrary::K2_DirectionBetweenSockets
#include "KismetAnimationLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns the normalized world-space direction vector from one named socket/bone to another on a skeletal mesh.
Caveats & Gotchas
- • Marked NotBlueprintThreadSafe — cannot run inside multithreaded Anim Graph evaluation like most of this library.
- • Always evaluates in world space; there is no space parameter, unlike K2_DistanceBetweenTwoSocketsAndMapRange.
- • Returns a zero vector if the two sockets/bones resolve to the same position, which can produce NaN downstream if that result is used to build a rotation without a zero-length check.
