20240423 131일차 언리얼 C++ 데이터 레이블 활용 케릭터 생성2

기초 캐릭터를 응용해서 ABP를 연결할 수 있다.

 

플레이어블 케릭터의 ABP에 데이터를 연산, 전달할 수 있다.

Base_Character를 상속받는 Hero의 input을 정의한다.

객체의 현재 이동설정과 이동정의, Input컨트롤에 대한 설정을 할 수 있다.

에니메이션을 생성하기 위해, DefaltAnimInstance를 생성한다.

DefaltAnimInstance

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

#pragma once

#include "CoreMinimal.h"
#include "Animation/AnimInstance.h"
#include "DefaltAnimInstance.generated.h"

/**

class ABaseCharacter;

UCLASS()
class FTPSGAME_API UDefaltAnimInstance : public UAnimInstance
{
	GENERATED_BODY()

	UPROPERTY(VisibleDefaultsOnly, BlueprintReadOnly, Category = "BlendSpace" , meta = (AllowPrivateAccess = "true"))
	bool bFalling;

	UPROPERTY(VisibleDefaultsOnly, BlueprintReadOnly, Category = "BlendSpace" , meta = (AllowPrivateAccess = "true"))
	float Speed;

	UPROPERTY(VisibleDefaultsOnly, BlueprintReadOnly, Category = "BlendSpace" , meta = (AllowPrivateAccess = "true"))

	UPROPERTY()
	TObjectPtr<ABaseCharacter> Owner;

public:
	virtual void NativeUpdateAnimation(float DeltaSeconds) override;

private:
	void UpdateBlendSpaceValue();

};

 

AninInstance를 사용할때, 값을 이용하기 위해 UPROPERTY() 로 사용하는, Falling(떨어지는지) Speed(현재속도) Direction(방향) 을 정의해놓는다.

 

C++에서만 사용할 수 있도록, ABaseCharacter 포인터 변수를 생성한다.

#include "Anim/DefaltAnimInstance.h"
#include "Utility/Helper.h"
#include "Actors/BaseCharacter.h"
#include "GameFramework/CharacterMovementComponent.h"
#include "KismetAnimationLibrary.h"

void UDefaltAnimInstance::NativeUpdateAnimation(float DeltaSeconds)
{
	Super::NativeUpdateAnimation(DeltaSeconds);

	Owner = Cast<ABaseCharacter>(TryGetPawnOwner());

	if (Owner == nullptr) return;

	UpdateBlendSpaceValue();
}

void UDefaltAnimInstance::UpdateBlendSpaceValue()
{
	bFalling = Owner->GetCharacterMovement()->IsFalling();

	Speed = Owner->GetVelocity().Size2D();

	FRotator Rotation = FRotator(0, Owner->GetActorRotation().Yaw, 0);
	Direction = CalculateDirection(Owner->GetVelocity(), Rotation);
}

생성자에서, Owner변수에 현재 Pawn의 owner를 지정해주고( ABP를 소유한 객체 ) 

 

UpdateBlendSpaceValue를 사용하여, 객체의 데이터값을 틱마다 업데이트 해준다.

ABP생성

ABP를 C++를 기준으로 정의하고 사용하기 위해 애니메이션 블루프린트 를 생성한다.

 

Defalt AnimInstance를 사용해서, 기본 Flaot값 등을 정의하고 사용할 수 있게 한다.

 

기반 블루프린트에서 정의하고 값을 사용한다.
