UAnimInstance::IsPlayingSlotAnimation

function Engine Blueprint Since 4.8

#include "Animation/AnimInstance.h"

Access: public Specifiers: UFUNCTIONBlueprintPure

Description

Returns true if the given animation asset is currently playing through the specified slot node. A second overload also returns the active UAnimMontage via an out parameter.

Caveats & Gotchas

• Returns false during the blend-out phase even though the slot is still contributing to the final pose — use IsSlotActive if you need to know whether the slot is blending.
• The non-Blueprint overload `IsPlayingSlotAnimation(Asset, SlotNodeName, OutMontage)` also exists for C++ callers who need the active montage pointer, but is not Blueprint-exposed.
