Anim notifies

Anim notifies are not guaranteed to be fired

Good explanation by Vaei:

“Don’t use notifies for important events. A lot of the time they simply don’t fire, you’ll start seeing then when testing game in actual production. Setting to branching point notify ensures they always fire. However branching point notifies don’t fire if there are 2 on the same frame, especialy common when its the start of a montage. Use my task node/plugin instead, it basically looks for notifies of a specific type, caches the time where they should play, and starts a timer, and broadcasts an event”

See PlayMontageAdvanced

Create your own Notify

First, make a subclass of UAnimNotify and add your own delegate and call it in the Notify override.

class PUSHTHEMALL_API UPTAEquipmentItemUseNotify : public UAnimNotify  
{  
    GENERATED_BODY()  
  
public:  
    virtual void Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, const FAnimNotifyEventReference& EventReference) override;  
};

Then you can know if an anim montage is using it by casting the notify events:

const auto& NotifyEvents = UseMontage->Notifies;  
for (auto& NotifyEvent : NotifyEvents)  
{
	if (const auto& UseNotify = Cast<UPTAEquipmentItemUseNotify>(NotifyEvent.Notify))  
    {
	    // Some callback setup  
    }  
}
