unreal-c++教程-第五章:创建你的角色

• 1.ACharacter常见操作
• • 1.1 创建ACharacter的子类BaseRole
  • 1.2 添加BaseRole的网格模型
  • • 1.2.1 修改BaseRole的Mesh的局部位置和旋转
  • 1.3 添加BaseRole的动画
  • • 1.3.1 创建AnimBlueprint
    • 1.3.2 在c++中指定角色的动画类

unreal里面，为了更方便游戏逻辑的构建，单独将角色行为抽象成ACharacter，里面定义了角色的
动画，网格等基本行为，基本可以满足绝大部分游戏的需求，这是一件非常棒的事情！

BaseRole.h

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

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

UCLASS()
class UNREALLABX_API ABaseRole : public ACharacter
{
	GENERATED_BODY()

public:
	// Sets default values for this character's properties
	ABaseRole();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:	
	// Called every frame
	virtual void Tick(float DeltaTime) override;

	// Called to bind functionality to input
	virtual void SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) override;

};

BaseRole.cpp

// Fill out your copyright notice in the Description page of Project Settings.


#include "BaseRole.h"

// Sets default values
ABaseRole::ABaseRole()
{
 	// 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;

}

// Called when the game starts or when spawned
void ABaseRole::BeginPlay()
{
	Super::BeginPlay();
	
}

// Called every frame
void ABaseRole::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

}

// Called to bind functionality to input
void ABaseRole::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);

}

可以前往mixamo下载你喜欢的模型还有动画

因为Unreal 的CDO的特性，所以，我们一般在构造里面实现整个角色内涵的创建

ABaseRole::ABaseRole()
{
 	// 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;
	auto val = this->GetMesh();
	auto asset = ConstructorHelpers::FObjectFinder(TEXT("SkeletalMesh'/Game/Demos/Mesh/BaseRole/BaseRole.BaseRole'"));
	val->SetSkeletalMesh(asset.Object);


}

这是我们加载的资源：

当然，你可以快捷的通过：

生成对应的引用字符串

我们应该让人物模型的位置往下偏移

基本操作是修改USkeletalMeshComponent的局部位置

比较奇葩的是，它并不会热更到当前的静态场景里面，我不清楚这是Bug还是，反正…

当然，你可以通过以下方式修复上述问题：

我们现在要讨论的另外一个问题，就是碰撞体的正前方

应该要与人物的SkeletalMeshComponent的正前方相同

就像默认角色的这样：

所以，我们可以通过以下代码来实现

对应的资源：

关键代码：

ABaseRole::ABaseRole()
{
 	// 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;
	auto mesh = this->GetMesh();
	auto asset = ConstructorHelpers::FObjectFinder(TEXT("SkeletalMesh'/Game/Demos/Mesh/BaseRole/BaseRole.BaseRole'"));
	mesh->SetSkeletalMesh(asset.Object);
	mesh->SetRelativeLocation(FVector(0, 0, -80));
	mesh->SetRelativeRotation(FRotator(0,-90, 0));
	ConstructorHelpers::FClassFinder meshAnima(TEXT("/Game/Demos/Animator/AnimBP/BaseRoleAnimBP"));
	auto animClass = meshAnima.Class;
	mesh->SetAnimClass(animClass);
}

当我们再度编译的时候，动画就播放了：

下一章，我们将联合第四章的PlayerController 实现 角色的控制
