3. UE5 GAS RPG 俯视角下弹簧臂和摄像机的配置

//角色本身的设置（俯视角游戏）
    GetCharacterMovement()->bOrientRotationToMovement = true; //设置为true，角色将朝移动的方向旋转
    GetCharacterMovement()->RotationRate = FRotator(0.f, 400.f, 0.f); //旋转速率
    GetCharacterMovement()->bConstrainToPlane = true; //约束到平面
    GetCharacterMovement()->bSnapToPlaneAtStart = true; //设置了上面一项为true，且此项设置为true，则在开始时与地面对齐

    bUseControllerRotationPitch = false;   //同时需要确保角色本身不跟随控制器旋转：

    SpringArm->SetRelativeRotation(FRotator(-45.f, 0, 0)); //设置相对旋转 设置俯视角度（Pitch负值）
    SpringArm->bUsePawnControlRotation = false;    //确保不随角色转向而转动
