UEC++ 虚幻5第三人称射击游戏（一）

  • 创建一个空白的C++工程

人物角色基本移动

  • 创建一个Character类
  • 添加一些虚幻商城中的基础动画
    在这里插入图片描述
  • 给角色类添加Camera与SPringArm组件
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "SpringArm")class USpringArmComponent* SpringArm;UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Camera")class UCameraComponent* Camera;// Sets default values
AMyCharacter::AMyCharacter()
{// Set this character to call Tick() every frame.  You can turn this off to improve performance if you don't need it.PrimaryActorTick.bCanEverTick = true;SpringArm = CreateDefaultSubobject<USpringArmComponent>(TEXT("SpringArm"));SpringArm->SetupAttachment(GetRootComponent());SpringArm->TargetArmLength = 400.f;SpringArm->bUsePawnControlRotation = true;Camera = CreateDefaultSubobject<UCameraComponent>(TEXT("Camera"));Camera->SetupAttachment(SpringArm);Camera->bUsePawnControlRotation = false;
}

角色基本移动增强输入系统MyCharacter.cpp

  • GetMovementComponent()->GetNavAgentPropertiesRef().bCanCrouch = true;：允许角色进行蹲伏（crouch）动作，并且能够影响导航代理（Navigation Agent）的行为
    • GetMovementComponent()：获取角色的移动组件
    • GetNavAgentPropertiesRef()：获取导航代理属性的引用。这些属性用于定义角色如何与导航系统交互，例如高度、半径、最大爬坡角度等。
    • .bCanCrouch = true;：设置导航代理的一个布尔属性，表示该角色可以进行蹲伏，并且在寻路过程中应当考虑其能通过更低矮的空间。这意味着在自动寻路时，引擎会考虑到角色在蹲伏状态下可以通过的高度限制区域。
  • Crouch与OnCrouch：虚幻自带的蹲伏函数
