创建FPSAIGuard类
不需要玩家输入，删除多余的函数
FPSAIGuard.h
#include "CoreMinimal.h"
#include "GameFramework/Character.h"
#include "FPSAIGuard.generated.h" UCLASS()
class FPSGAME_API AFPSAIGuard : public ACharacter
{
GENERATED_BODY() public:
AFPSAIGuard(); protected:
virtual void BeginPlay() override; public:
virtual void Tick(float DeltaTime) override;
};
FPSAIGuard.cpp
#include "FPSAIGuard.h" AFPSAIGuard::AFPSAIGuard()
{
PrimaryActorTick.bCanEverTick = true; } void AFPSAIGuard::BeginPlay()
{
Super::BeginPlay(); } void AFPSAIGuard::Tick(float DeltaTime)
{
Super::Tick(DeltaTime);
}
导入角色资源
创建蓝图继承自FPSAIGuard类
命名为BP_Guard
对蓝图类进行初始化，设置网格体组件和动画
在FPSGame.Build.cs添加AI模块
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore" ,"AIModule"});
在FPSAIGuard.h定义一个人形体感应组件，可用于发现玩家人物并听到为发射物创建的声音
UPROPERTY(VisibleAnywhere,Category="Components")
UPawnSensingComponent* PawnSensingComp;
前向声明
class UPawnSensingComponent;
在FPSAIGuard.cpp初始化变量
PawnSensingComp = CreateDefaultSubobject<UPawnSensingComponent>(TEXT("PawnSensingComp"));
