我创造了一个FPS运动但玩家的动作是错误的 . 当向左或向右旋转时，播放器仍然向前移动 .
PlayerMovement.cs
public class PlayerMovement : MonoBehaviour
{
private Vector3 movement;
private Rigidbody rigid;
private bool jumpPressed;
private const int MOVEMENT_SPEED = 8;
private const int JUMP_POWER = 20;
private void Awake()
{
rigid = GetComponent<Rigidbody>();
}
private void Update()
{
SetInputs();
}
private void FixedUpdate()
{
Jump();
Move();
}
private void SetInputs()
{
movement.x = Input.GetAxis("Horizontal") * MOVEMENT_SPEED;
movement.y = rigid.velocity.y;
movement.z = Input.GetAxis("Vertical") * MOVEMENT_SPEED;
jumpPressed = Input.GetKeyDown(KeyCode.Space);
}
private void Jump()
{
if (jumpPressed && GroundCheck())
{
movement.y = JUMP_POWER;
jumpPressed = false;
}
}
private void Move()
{
rigid.velocity = movement;
}
private bool GroundCheck()
{
return true;
}
}
CameraMovement.cs
public class CameraMovement : MonoBehaviour
{
private Transform player;
private Vector2 rotation;
private Quaternion originalRotation;
private const int HORIZONTAL_ROTATION_SPEED = 5;
private const int VERTICAL_ROTATION_SPEED = 5;
private const int VERTICAL_ROTATION_MIN = -80;
private const int VERTICAL_ROTATION_MAX = 80;
private void Awake()
{
player = GameObject.FindGameObjectWithTag("Player").transform;
}
private void Start()
{
originalRotation = transform.localRotation;
}
private void Update()
{
SetInputs();
RotateCamera();
RotatePlayer();
}
private void SetInputs()
{
rotation.x = Input.GetAxisRaw("Mouse X") * HORIZONTAL_ROTATION_SPEED;
rotation.y += Input.GetAxisRaw("Mouse Y") * VERTICAL_ROTATION_SPEED;
rotation.y = Mathf.Clamp(rotation.y, VERTICAL_ROTATION_MIN, VERTICAL_ROTATION_MAX);
}
private void RotateCamera()
{
Quaternion verticalRotation = Quaternion.AngleAxis(rotation.y, Vector3.left);
transform.localRotation = originalRotation * verticalRotation;
}
private void RotatePlayer()
{
player.localRotation *= Quaternion.AngleAxis(rotation.x, player.up);
}
}
我提供了一个小gif，显示旋转时的错误动作 .

通过旋转相机旋转播放器时，播放器围绕其y轴正确旋转 . 不知怎的，他没有前进到他面对的方向，他只是向一个方向移动 .
需要修复什么？

我看到你的移动逻辑不处理相机面向方向，它只是使对象随输入轴值移动，这就是你的对象像这样移动的原因 .
如果你想让'向前'轴意味着'向前走到我面向的方向'，你应该将运动与相机旋转结合起来 .
你可以尝试类似的东西
在你的Move（）中 .
这是重新发明轮子 . 统一标准资产包随附fps预制件，可自定义并且运行良好 . 该脚本非常强大，控件很优雅，只需稍加调整即可轻松实现，省时，从Unity商店下载
Unity Standard Asset软件包，并使用firstperson char预制件 . 我想你会很高兴的 .
