写一份ue5关于角色移动的代码

以下是一个基本的UE5角色移动代码示例：

// CharacterMovement.h

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/CharacterMovementComponent.h"
#include "CharacterMovement.generated.h"

UCLASS()
class YOURPROJECT_API UCharacterMovement : public UCharacterMovementComponent
{
    GENERATED_BODY()

public:
    UCharacterMovement();

    virtual void TickComponent(float DeltaTime, enum ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;

    void MoveForward(float Value);
    void MoveRight(float Value);

private:
    FVector CurrentVelocity;
};

// CharacterMovement.cpp

#include "CharacterMovement.h"

UCharacterMovement::UCharacterMovement()
{
    // 设置默认的移动速度等参数
    MaxWalkSpeed = 500.f;
}

void UCharacterMovement::TickComponent(float DeltaTime, enum ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
    Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

    // 根据当前速度移动角色
    GetOwner()->AddActorWorldOffset(CurrentVelocity * DeltaTime, true);
}

void UCharacterMovement::MoveForward(float Value)
{
    // 计算前后移动的速度向量
    FRotator Rotation = GetOwner()->GetActorRotation();
    FVector Direction = FRotationMatrix(Rotation).GetScaledAxis(EAxis::X);
    CurrentVelocity = Direction * MaxWalkSpeed * Value;
}

void UCharacterMovement::MoveRight(float Value)
{
    // 计算左右移动的速度向量
    FRotator Rotation = GetOwner()->GetActorRotation();
    FVector Direction = FRotationMatrix(Rotation).GetScaledAxis(EAxis::Y);
    CurrentVelocity = Direction * MaxWalkSpeed * Value;
}

请确保在UE5中正确安装并设置了CharacterMovement组件，并将上述代码添加到您的项目中的相应文件中。然后，您可以在Character类中调用MoveForward和MoveRight函数来控制角色的移动，如下所示：

// YourCharacter.h

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "YourCharacter.generated.h"

UCLASS()
class YOURPROJECT_API AYourCharacter : public ACharacter
{
    GENERATED_BODY()

public:
    AYourCharacter();

protected:
    virtual void SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) override;

private:
    void MoveForward(float Value);
    void MoveRight(float Value);

    UCharacterMovement* CharacterMovementComponent;
};

// YourCharacter.cpp

#include "YourCharacter.h"
#include "CharacterMovement.h"

AYourCharacter::AYourCharacter()
{
    PrimaryActorTick.bCanEverTick = true;
    CharacterMovementComponent = CreateDefaultSubobject<UCharacterMovement>(TEXT("CharacterMovementComponent"));
}

void AYourCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
    Super::SetupPlayerInputComponent(PlayerInputComponent);

    // 绑定输入事件
    PlayerInputComponent->BindAxis("MoveForward", this, &AYourCharacter::MoveForward);
    PlayerInputComponent->BindAxis("MoveRight", this, &AYourCharacter::MoveRight);
}

void AYourCharacter::MoveForward(float Value)
{
    CharacterMovementComponent->MoveForward(Value);
}

void AYourCharacter::MoveRight(float Value)
{
    CharacterMovementComponent->MoveRight(Value);
}

在UE5中，您可以通过在Project Settings中的Input选项卡中设置映射来为输入轴绑定MoveForward和MoveRight函数。
