ProjectA - EnhancedInput(Move, Look)(2023/12/26)

일단 강의 들은거랑 내 창작물을 만드는 거랑은 확실히 다르다.

 

Belica_HeavyArmor

 

캐릭터를 바꾸었다

이 에셋이다.

 

Input

 

 

Player가 움직일 수 있도록 Move와 Look 함수를 만들어준다.

그다음 위에있는 Action과 MappingContext를 생성하자.

 

PACharacterPlayer.h

#include "InputActionValue.h"




protected:
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UInputMappingContext> DefaultMappingContext;
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UInputAction> JumpAction;
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UInputAction> MoveAction;
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UInputAction> LookAction;
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Input, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UInputAction> ChangeCameraAction;

	void Move(const FInputActionValue& Value);
	void Look(const FInputActionValue& Value);

	const FRotator Rotation = Controller->GetControlRotation();
	const FRotator YawRotation(0, Rotation.Yaw, 0);

	const FVector ForwardDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::X);
	const FVector RightDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y);

	AddMovementInput(ForwardDirection, MovementVector.X);
	AddMovementInput(RightDirection, MovementVector.Y);
}

void APACharacterPlayer::Look(const FInputActionValue& Value)
{
	FVector2D LookAxisVector = Value.Get<FVector2D>();

	AddControllerPitchInput(LookAxisVector.Y);
}

 

향상된 입력 시스템으로 1인칭 카메라, 3인칭 카메라를 바꾸려고 하는데 잘 진행되지 않는다.

 

 

오늘 하면서 시간을 많이 소모한 것이 InputAction 설정과 헤더파일이었다...

FInputActionValue라는 구조체를 사용하려면 

#include "InputActionValue.h"

이 헤더파일을 추가하거나 EnhancedInputComponent.h파일을 추가해줘야 한다.

 

그리고 또 까먹을 수 있으니 MappingContext의 설정 스샷을 여기다 남긴다.

 

필자는 애니메이션은 파라곤애니메이션 그대로 사용했다.

일단은.

 

결과물은 잘 되는 것 같다.
