此为ue课程Unreal Engine 5 C++ The Ultimate Game Developer Course第9节的笔记

87、the animation blueprint

使动作能够循环

动画事件蓝图

状态机设置

条件设置

动画设置

88、the anim instance

创建动画蓝图c++类

删掉原本的事件蓝图

将继承的类改为c++类

------------SlashAnimInstance.h-----------
#include "CoreMinimal.h"
#include "Animation/AnimInstance.h"
#include "SlashAnimInstance.generated.h"

/**
 * 
 */
UCLASS()
class MYPROJECT_API USlashAnimInstance : public UAnimInstance
{
	GENERATED_BODY()
public:
	virtual void NativeInitializeAnimation() override;
	virtual void NativeUpdateAnimation(float DeltaTime) override;

	UPROPERTY(BlueprintReadOnly)
	class ASlashCharacter* SlashCharacter;

	UPROPERTY(BlueprintReadOnly, Category = Movement)
	class UCharacterMovementComponent* SlashCharacterMovement;

	UPROPERTY(BlueprintReadOnly, Category = Movement)
	float GroundSpeed;
};

-------------SlashAnimInstance.cpp-------------
#include "Characters/SlashAnimInstance.h"
#include "Characters/SlashCharacter.h"
#include "GameFramework/CharacterMovementComponent.h"
#include "Kismet/KismetMathLibrary.h"

void USlashAnimInstance::NativeInitializeAnimation()
{
	Super::NativeInitializeAnimation();
	SlashCharacter = Cast<ASlashCharacter>(TryGetPawnOwner());
	if (SlashCharacter)
	{
		SlashCharacterMovement = SlashCharacter->GetCharacterMovement();
	}
}

void USlashAnimInstance::NativeUpdateAnimation(float DeltaTime)
{
	Super::NativeUpdateAnimation(DeltaTime);
	if (SlashCharacterMovement)
	{
		GroundSpeed = UKismetMathLibrary::VSizeXY(SlashCharacterMovement->Velocity);
	}
}

每一次按ctrl +f5时，game mode都会被重置，可以将当前的关卡另存为其他关卡保存gamemode设置

89、jumping

------------SlashCharacter.cpp-------------
void ASlashCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);
	PlayerInputComponent->BindAxis(FName("MoveForward"), this, &ASlashCharacter::MoveForward);
	PlayerInputComponent->BindAxis(FName("Turn"), this, &ASlashCharacter::Turn);
	PlayerInputComponent->BindAxis(FName("LookUp"), this, &ASlashCharacter::LookUp);
	PlayerInputComponent->BindAxis(FName("MoveRight"), this, &ASlashCharacter::MoveRight);

	PlayerInputComponent->BindAction(FName("Jump"), IE_Pressed, this, &ACharacter::Jump);
}

90、jump animation

----------SlashAnimInstance.h---------
	UPROPERTY(BlueprintReadOnly, Category = Movement)
	bool IsFalling;

-----------SlashAnimInstance.cpp--------------
void USlashAnimInstance::NativeUpdateAnimation(float DeltaTime)
{
	Super::NativeUpdateAnimation(DeltaTime);
	if (SlashCharacterMovement)
	{
		GroundSpeed = UKismetMathLibrary::VSizeXY(SlashCharacterMovement->Velocity);
		IsFalling = SlashCharacterMovement->IsFalling();
	}
}
