ACharacter::IsPlayingRootMotion

function Engine Blueprint Since unknown

#include "GameFramework/Character.h"

Access: public Specifiers: UFUNCTIONBlueprintCallableconst

Description

Returns true if an AnimMontage with root motion mode RootMotionFromMontagesOnly is currently active. Use this to check whether the networked anim root motion code path is enabled.

Caveats & Gotchas

• This checks only anim-montage root motion, not FRootMotionSource instances. If you need to detect all active root motion types (including those added via ApplyRootMotionSource), call HasAnyRootMotion() instead.
• Returns false during the brief window after a montage ends but before the character fully transitions back to non-root-motion movement, which can cause one-frame logic errors in tick-based checks.
