# 1. 轴映射设置 #

如下四个映射

MoveForWard
    MoveRight
    Turn
    LookUp

# 2. 移动 #

头文件添加下面两行

void MoveForward(float value);
    	void MoveRight(float value);

有番茄助手的话，直接右键添加实现，因为我这里已经实现过了，显示灰色。没有实现的时候是白色的点一下就可以了。

Cpp文件中添加如下代码

PlayerInputComponent->BindAxis(TEXT("MoveForward"), this, &AMainCharacter::MoveForward);
    	PlayerInputComponent->BindAxis(TEXT("MoveRight"), this, &AMainCharacter::MoveRight);

AddMovementInput(UKismetMathLibrary::GetForwardVector(GetControlRotation()), value);

AddMovementInput(UKismetMathLibrary::GetRightVector(GetControlRotation()), value);

头文件添加这两个

#include "Kismet/KismetMathLibrary.h"
    #include "Components/InputComponent.h"

右键创建基于角色c++的蓝图

编译之后运行，发现可以控制玩家移动，不能上下左右看![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1Njk3OTc4_size_16_color_FFFFFF_t_70 7][]

# 3. 视角变换 #

Cpp文件添加如下2行代码即可

PlayerInputComponent->BindAxis(TEXT("Turn"), this, &AMainCharacter::AddControllerYawInput);
    	PlayerInputComponent->BindAxis(TEXT("LookUp"), this, &AMainCharacter::AddControllerPitchInput);

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1Njk3OTc4_size_16_color_FFFFFF_t_70 8][]

添加玩代码，编译后发现可以左右转不能上下转，于是在这里加这行代码

SpringArm->bUsePawnControlRotation = true;

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1Njk3OTc4_size_16_color_FFFFFF_t_70 9][]

注意这里两行代码顺序，上图编译之后发现前后移动不顺畅，改了顺序之后可以移动，但是上下还是不能旋转

来到蓝图发现这里还是没有被修改，可能是哪里出问题了，于是直接修改蓝图里面发现可以移动
