UE4 从无到有纯 C++ & Slate 开发沙盒游戏(十八) 添加玩家模型与相机
上一部分吧 GameMode 都绑定好了，现在把模型和相机放到 PlayerCharacter 上去
先做准备工作
如果我们写C++文件想要看到实时的效果，需要在 Content 下加个 Blueprint 文件夹，其下再创建个 Temp 文件夹，这个Temp 中保存写的一些蓝图，这些蓝图在项目完成以后是不需要的。
添加蓝图
由于我们是要一边写 PlayerCharacter 一边看他的效果，所以我们要选择创建一个继承自 PlayerCharacter 的蓝图，命名为 PlayerCharacterBP
这样便可以修改C++代码的同时动态的看到其实时效果
D:\UE4 Project\UE26.2\CourseProject\SlAiCourse\Source\SlAiCourse\Private\Player\SlAiPlayerCharacter.cpp
1 #include "Player/SlAiPlayerCharacter.h" 2 3 4 // Sets default values 5 ASlAiPlayerCharacter::ASlAiPlayerCharacter() 6 { 7 // Set this character to call Tick() every frame. You can turn this off to improve performance if you don't need it. 8 PrimaryActorTick.bCanEverTick = true; 9 10 /** 11 * 创建 Component（属性） 12 * CreateDefaultSubobject<T>() 在构造函数中创建使用 13 * NewObject<T> 如果要在其他位置的代码或者蓝图中创建，可以用 NewObject，用来创建 Uobject 类型 14 */ 15 16 /** 17 * 给默认 Mesh 添加骨骼模型 18 * 19 * Uobject 资源加载 20 * ConstructorHelpers::FObjectFinder<T>只能在构造函数使用 21 * LoadObiect<T>可以在任何地方使用 22 * 23 * 蓝图资源加载 24 * ConstructorHelpers::FClassFinder <T>只能在构造函数使用 25 * LoadClass<T>可以在任何地方加载 26 * 27 * 全局加载资源函数 28 * StaticLoadObject、StaticLoadClass 29 * 应该是早期的LoadObiect<T>和LoadClass<T>的版本 30 */ 31 static ConstructorHelpers::FObjectFinder<USkeletalMesh> StaticMeshThird(TEXT("SkeletalMesh'/Game/AssetsvilleTown/Meshes/Characters/SK_citizen_female_10.SK_citizen_female_10'")); 32 GetMesh()->SetSkeletalMesh(StaticMeshThird.Object); 33 GetMesh()->bOnlyOwnerSee = true; //如果该值为True，则该组件仅在视图参与者是该组件的所有者时才可见。直接或间接。 34 GetMesh()->bReceivesDecals = false; //是否接收光线反射 35 GetMesh()->SetCollisionObjectType(ECC_Pawn); //在骨架网格上设置碰撞对象类型 36 GetMesh()->SetCollisionEnabled(ECollisionEnabled::NoCollision); //我们的碰撞都会放到根组件的椭圆碰撞，这里设置无碰撞 37 GetMesh()->SetCollisionResponseToChannels(ECR_Ignore); //让这个Mesh忽略所有的碰撞 38 GetMesh()->SetRelativeLocation(FVector(0.f, 0.f, -95.f)); //设置位置 39 GetMesh()->SetRelativeRotation(FQuat::MakeFromEuler(FVector(0.f, 0.f, -90.f))); //设置旋转 40 } 41 42 // Called when the game starts or when spawned 43 void ASlAiPlayerCharacter::BeginPlay() 44 { 45 Super::BeginPlay(); 46 } 47 48 // Called every frame 49 void ASlAiPlayerCharacter::Tick(float DeltaTime) 50 { 51 Super::Tick(DeltaTime); 52 } 53 54 // Called to bind functionality to input 55 void ASlAiPlayerCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) 56 { 57 Super::SetupPlayerInputComponent(PlayerInputComponent); 58 }
可以看到第三人称的模型已经放到了原点，拥有正的朝向和高度，碰撞属性也都配置好了
下面是第一人称的配置
