I’v inserted my native notifier to the animation but when i try to use it, it won’t fire.

This is the header:

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "Animation/AnimNotifies/AnimNotify.h"
#include "Enemy_Hit_Notifier.generated.h"

UCLASS()
class OLDSCHOOLNIGHTMARE_API UEnemy_Hit_Notifier : public UAnimNotify
{
	GENERATED_UCLASS_BODY()

	virtual bool Received_Notify(USkeletalMeshComponent* MeshComp, UAnimSequence* AnimSeq) const;
};

This is the source file:

// Fill out your copyright notice in the Description page of Project Settings.

#include "OldSchoolNightmare.h"
#include "Enemy_Hit_Notifier.h"
#include "Enemy_Character.h"


UEnemy_Hit_Notifier::UEnemy_Hit_Notifier(const FObjectInitializer& ObjectInitializer /*= FObjectInitializer::Get()*/)
	: Super(ObjectInitializer)
{
}

bool UEnemy_Hit_Notifier::Received_Notify(USkeletalMeshComponent* MeshComp, UAnimSequence* AnimSeq) const
{
	UE_LOG(LogTemp, Warning, TEXT("Animation Hit Notifying!"));
	AEnemy_Character* character = Cast<AEnemy_Character>(MeshComp->GetOwner());
	character->Hit_Notify();
	return true;
}

It supposed to log “Animation Hit Notifying!”, but it is not logging anything, am i missing something ?

Hi , this code work OK? I Copy/paste but not working… Are you changed someting to do this work?

Thank you. Best regards.

Well, in my case i had main c++ enemy class and blueprint class that inherits from it, so instead of implementing the notify event in c++, i’v made a blueprintevent(in c++) that i can call inside the animationBlueprint, and in the animationBlueprint i triggered this event with the animation notifier that within the blueprint.
this is how it looks like:

animInstanceCPPClass->blueprint_child(with anim notify).

Note that animationBlurprint is actually animationInstance, and this is the class you need to extended in c++ and then make a blueprint child from it.

If i’m not mistaken, this is the type of event you need to implement inside the c++ class:

someHeader:

UFUNCTION( BlueprintImplementableEvent, Category=something)
void event_for_blueprint();

and after you call it from the blueprint, it supposed to activate the function inside the cpp class:

void someHeader::event_for_blueprint()
{
w/e…
}

Hi . After days working, I could fix the problem.

Please take a look:

bool UMyAnimNotifyState::Received_Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation) const
{
//	UE_LOG(LogTemp, Warning, TEXT("Animation Hit Notifying!"));
//	AEnemy_Character* character = Cast<AEnemy_Character>(MeshComp->GetOwner());
//	character->Hit_Notify();
	return true;
}


UCLASS()
class BATALLA_API UMyAnimNotifyState : public UAnimNotify
{
	GENERATED_UCLASS_BODY()

//	virtual bool Received_Notify(class USkeletalMeshComponent* MeshComp, class UAnimSequence* AnimSeq) const;
virtual bool Received_Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation) const override;

}

This is working perfect to me.

“override” was the keyword.

Thank you.
Best regards.

Omg lol, Thanks for sharing the solution :smiley:

GREAT!!!

Now, if I have the “USkeletalMeshComponent” how can I get the ACharacter ???

bool UMyAnimNotifyState::Received_Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation) const
 {
//  ACharacter actor = MeshComp->GetActor();    LOL  LOL  LOL  LOL

//  ACharacter actor = MeshComp->AActor;    LOL  LOL  LOL  LOL
 
     return true;
 }

Thank you, best regards.

SOLVED from your code.

ATropaCharacter* character = Cast<ATropaCharacter>(MeshComp->GetOwner());

Thank you!! Best regards.
