UAnimInstance::OnMontageStarted

property Engine Blueprint Since 4.5

#include "Animation/AnimInstance.h"

Access: public Specifiers: UPROPERTYBlueprintAssignable

Description

Delegate broadcast immediately when a montage begins playing, at the start of its blend-in phase. Use this to react to the moment a montage is activated, for example to set state flags or start correlated effects.

Caveats & Gotchas

• Fires at the very beginning of blend-in, so the montage has weight 0 on this frame. If you need to react after the animation has fully taken over the pose, use OnMontageBlendedIn instead.
• This delegate is per AnimInstance, not per montage asset. If multiple montages can play, always check the Montage parameter to determine which one started before acting.

Example

Set bIsAttacking flag when attack montage starts C++

AnimInstance->OnMontageStarted.AddDynamic(this, &AMyCharacter::OnMontageStarted);

void AMyCharacter::OnMontageStarted(UAnimMontage* Montage)
{
    if (Montage == AttackMontage)
    {
        bIsAttacking = true;
    }
}
