Godot播放器没有朝这个方向走

Question

所以我是 godot 的新手，我遇到了问题。当相机移动时，玩家的身体不会跟随相机当我用相机环顾四周时，玩家的身体保持不变，例如如果我向右转时使用wasd，那将是aswd。球员运动很艰难，但我得到了帮助。如果您能提供帮助，那将非常酷，我只是想学习编码。这对我来说很难。

p.s 抱歉语法不好

如果您希望移动基于相机的方向...

然后根据移动：

var direction = Vector3.ZERO

if Input.is_action_pressed("move_right"):
    direction.x += 1
if Input.is_action_pressed("move_left"):
    direction.x -= 1
if Input.is_action_pressed("move_back"):
    direction.z += 1
if Input.is_action_pressed("move_forward"):
    direction.z -= 1

关于camera的方向。

我们将使用camera.global_transform.basis。 transform 的 basis 为我们提供了一组与变换空间的轴对齐的向量。

使用camera.transform 代替camera.global_transform 将不起作用，因为Camera 是KinematicBody 的子代。

那么你的代码最终是这样的：

var direction = Vector3.ZERO
var camera_x = camera.global_transform.basis.x
var camera_z = camera.global_transform.basis.z

if Input.is_action_pressed("move_right"):
    direction += camera_x
if Input.is_action_pressed("move_left"):
    direction -= camera_x
if Input.is_action_pressed("move_back"):
    direction += camera_z
if Input.is_action_pressed("move_forward"):
    direction -= camera_z
