无法在gdscript中添加相机旋转

Question

我试图在Godot中给我的角色添加相机旋转，但我一直收到错误消息“在基本的‘Vector3’中对函数'rotated‘的无效调用。预期的2个参数”我尝试将方向变量设为向量2，但当我这样做时，使我的bean角色跳跃的物理函数将不起作用，因为必须有另一个轴可以在代码中移动：(错误来自第58行)

Answer 1

旋转后的函数需要两个参数，请参阅gdscript手册：

轴旋转(轴: Vector3，phi：

Vector3 )

将此向量绕给定轴旋转φ弧度。轴必须是规范化的向量。

因此，像这样的东西

direction = direction.normalized().rotated(Vector3(0,-1,0),rotation.y)
