UAnimInstance::ClearAllTransitionEvents

function Engine Blueprint Since 5.3

#include "Animation/AnimInstance.h"

Access: public Specifiers: ENGINE_APIUFUNCTIONBlueprintCallable

Description

Removes every queued transition request regardless of event name. Useful for resetting the state machine's pending transitions to a clean slate, such as on respawn or when a character enters a ragdoll state.

Caveats & Gotchas

• Clears ALL pending events — if multiple systems request different transitions in the same frame, a blanket clear from one system will silently discard the others' requests.
• Like ClearTransitionEvents, this is BlueprintThreadSafe, but note that the state machine evaluates transitions during the parallel anim update thread; there is a narrow window each tick where a cleared event may still have been evaluated.
