Player Character / Refactoring

说明

STUBaseCharacter作为STUAICharacter和STUPlayerCharacter的基类

创建STUPlayerCharacter

-
基类	STUBaseCharacter
路径	Player
名称	STUPlayerCharacter
属性	Public

从STUBaseCharacter中移除文本组件

下一章会给出其他实现

15
16// OnChangeHealth
17// HealthTextComponent->SetText(FText::FromString(FString::Printf(TEXT("%.0f"), HealthComponent->GetHealth())));

弹簧臂组件和摄像机组件

 9    SpringArmComponent->SetupAttachment(GetRootComponent());
10    SpringArmComponent->bUsePawnControlRotation = true;
11    SpringArmComponent->SocketOffset = FVector(0.0f, 100.0f, 80.0f);
12
13    CameraComponent = CreateDefaultSubobject<UCameraComponent>("CameraComponent");
14    CameraComponent->SetupAttachment(SpringArmComponent);
15}

屏蔽STUBaseCharacter的弹簧臂组件和摄像机组件

键位绑定

在STUPlayerCharacter中实现

ShootThemUp: Player/STUPlayerCharacter.cpp

Copy 1#include "Components/InputComponent.h"
 2#include "Components/STUWeaponComponent.h"
 3
 4void ASTUPlayerCharacter::SetupPlayerInputComponent(UInputComponent *PlayerInputComponent)
 5{
 6    Super::SetupPlayerInputComponent(PlayerInputComponent);
 7
 8    PlayerInputComponent->BindAxis("MoveForward", this, &ASTUPlayerCharacter::MoveForward);
 9    PlayerInputComponent->BindAxis("MoveRight", this, &ASTUPlayerCharacter::MoveRight);
10    PlayerInputComponent->BindAxis("Lookup", this, &ASTUPlayerCharacter::AddControllerPitchInput);
11    PlayerInputComponent->BindAxis("TurnAround", this, &ASTUPlayerCharacter::AddControllerYawInput);
12    PlayerInputComponent->BindAction("Jump", IE_Pressed, this, &ASTUPlayerCharacter::Jump);

22{
23    IsForward = Amount > 0.0f;
24    if (Amount == 0.0f) return;
25    AddMovementInput(GetActorForwardVector(), Amount);
26}
27
28void ASTUPlayerCharacter::MoveRight(float Amount)
29{
30    if (Amount == 0.0f) return;
31    AddMovementInput(GetActorRightVector(), Amount);

屏蔽STUBaseCharacter的键位绑定

动画蓝图和游戏角色运动组件使用IsRunning接口

STUBaseCharacter将之设为虚函数, 返回false

ShootThemUp: Player/STUBaseCharacter.h

Copy1UFUNCTION(BlueprintCallable)
2virtual bool IsRunning() const;

ShootThemUp: Player/STUBaseCharacter.cpp

Copy1bool ASTUBaseCharacter::IsRunning() const
2{
3    return false;
4}

STUPlayerCharacter对其覆写

不需要给出UFUNCTION

ShootThemUp: Player/STUPlayerCharacter.h

Copy1virtual bool IsRunning() const override;

ShootThemUp: Player/STUPlayerCharacter.cpp

Copy1bool ASTUPlayerCharacter::IsRunning() const
2{
3    return AbleRun && IsForward && !GetVelocity().IsZero();
4}

游戏角色死亡时切换到观察者状态

STUBaseCharacter屏蔽OnDeath中切换控制器状态

ShootThemUp: Player/STUBaseCharacter.cpp

Copy1// #include "GameFramework/Controller.h"
2
3/*
4  if (Controller)
5  {
6  Controller->ChangeState(NAME_Spectating);
7  }
8*/

STUPlayerCharacter覆写OnDeath

ShootThemUp: Player/STUPlayerCharacter.h

Copy1virtual void OnDeath() override;

ShootThemUp: Player/STUPlayerCharacter.cpp

Copy 1#include "GameFramework/Controller.h"
 2
 3void ASTUPlayerCharacter::OnDeath()
 4{
 5    Super::OnDeath();
 6
 7    if (Controller)
 8    {
 9        Controller->ChangeState(NAME_Spectating);
10    }
11}

关卡使用STUPlayerCharacter

1. 创建基于STUPlayerCharacter的蓝图类, 命名为BP_STUPlayerCharacter, 保存到 Content/Player
   

2. 设置关卡DefaultPawnClass
   

   

   
   

设置BP_STUPlayerCharacter

参照 进阶课程 > 非玩家游戏角色行为 > 让NPC移动到指定位置 > 配置BP_STUAICharacter

至此, 可以删除BP_STUBaseCharacter
