UAnimInstance::HasNativeTransitionBinding
#include "Animation/AnimInstance.h"
Access: public
Specifiers: constENGINE_API
Description
Checks whether a native C++ delegate is bound to the specified state machine transition. Returns true if a binding exists and outputs the binding name.
Caveats & Gotchas
- • Only detects bindings added via AddNativeTransitionBinding — it does not report Blueprint-defined transition rules.
- • State and machine names are case-sensitive and must match the Animation Blueprint graph exactly.
