UAnimInstance::Montage_SetPlayRate
#include "Animation/AnimInstance.h"
Access: public
Specifiers: UFUNCTIONBlueprintCallable
Description
Changes the playback speed of an active montage without restarting it. Use this to slow down or speed up an animation in response to gameplay events.
Caveats & Gotchas
- • Setting NewPlayRate to 0.0 has the same visible effect as Montage_Pause but the internal state differs — the montage is still considered 'playing' and will not fire the OnMontageEnded delegate unless explicitly stopped.
- • Negative play rates are not supported and will produce undefined behavior; use Montage_JumpToSection to play segments in reverse if needed.
