指定骨骼模型并调整胶囊体
- 指定骨骼模型
-
C++硬编码给出默认值
-
头文件胶囊体#include “Components/CapsuleComponent.h”
//设置胶囊体的默认宽高
GetCapsuleComponent()->SetCapsuleSize(35.f, 100.f);
创建轴映射与GameMode
- 创建关卡GameMode子类
- 设置玩家使用默认类
- 轴映射
基本简单移动与旋转控制
- AddMovementInput：沿着给定的世界方向向量(通常是标准化的)添加移动输入，并按“ScaleValue”进行缩放。如果ScaleValue < 0，则移动方向相反。基础Pawn类不会自动应用移动，这取决于用户在Tick事件中这样做。像Character和DefaultPawn这样的子类会自动处理这些输入并移动。
-
GetActorForwardVector：获取Actor，X轴正向的向量
-
GetActorRightVector：获取Actor，Y轴正向的向量

控制角色旋转
- 相机的选择和角色的旋转应该是两个独立的事件
- 我们需要分离控制相机的鼠标控制旋转（ControlRotation）和角色旋转（Pawn Rotation）。
- 在UE中XYZ轴的正向分别对应前方、右方和上方，显示的箭头颜色分别为红色、绿色和蓝色（三基色的习惯顺序）。
- 头文件 #include “GameFramework/PlayerController.h”
- Controller：这是Character类中自己声明的AController* 属性，用与获取该Actor的控制器

}
使角色自动面向移动方向
- CharacterMovement非常强大，我们打开CharacterMovement的Orient Rotation to Movement就开启自动面向旋转
- 头文件：#include “GameFramework/CharacterMovementComponent.h”
//硬编码orient Rotation to Movement,给个默认转向速率
GetCharacterMovement()->bOrientRotationToMovement = true;
GetCharacterMovement()->RotationRate = FRotator(0.f, 500.f, 0.f);
- 运行结果
创建键盘与手柄使用的视角与旋转函数
- 新建两个float变量来控制上下左右转向的速率，注意旋转时要乘以DeltaTime避免高低性能差值
float BaseTurnRate; //使用键盘X转向的速率
float BaseLookUpRate; //使用键盘Y转向的速率
//给键盘控制转向的速率变量赋初值
BaseTurnRate = 21.f;
BaseLookUpRate = 21.f;
- 因为可能要修改视角限制，新建Turn与LookUp绑定Controller控制器去管理视角旋转函数，新建绑定键盘鼠标轴映射事件函数

void MoveForward(float value);
void MoveRight(float value);
void Turn(float Value);
void LookUp(float Value);

限制角色上下视角旋转的范围

void AMainPlayer::LookUp(float Value)
{
//UE_LOG(LogTemp, Warning, TEXT("%f"), GetControlRotation().Pitch);
//
//控制视角
if (GetControlRotation().Pitch < 270.f && GetControlRotation().Pitch >180.f && Value > 0.f)
{
return;
}
else if (GetControlRotation().Pitch < 180.f && GetControlRotation().Pitch >45.f && Value < 0.f)
{
return;
}
AddControllerPitchInput(Value);

混合空间(BlendSpace)
- 创建BlendSpace1D，并给出相应的骨骼
- 将相应的行走、奔跑、动画添加上去
动画蓝图的创建
- 创建动画蓝图，选择自己的骨骼
创建给动画蓝图提供逻辑的AnimInstance子类
- 创建AnimInstance子类
- 写入判断是否奔跑与跳跃的变量，MainPlayer类的指针方便到时候好获取参数参与UE反射，重写NativeInitializeAnimation，这个函数类似与BeginPlay，然后加入一个实时更新的函数在Animation蓝图中使用

- 给动画蓝图指定父类
制作移动动画设置到角色
- 连接我们的更新函数
- 新建一个状态机
- 在状态机里面在添加一个状态
- 然后再到此状态里面把混合空间与编码的speed加上
- 返回最开始的动画图表连接上最终动画
- 最后将混合空间添加到角色蓝图Mesh的Animation中就可
制作跳跃动画设置到角色
-
将跳跃的三个状态添加到状态机中
-
首先判断是否起跳，用C++编写好的变量进行判断
-
监测起跳动作，当跳跃动作快播放完了的时候就得开始切换，一般我们常用这个Timer Remaining(ratio)：剩余计时器(比例)来进行使用判断监测
-
判断是否落下
