如何修复我的鼠标不在 X 轴上旋转相机？

Question

所以我的问题在于我的可控第一人称相机，它目前只是一个带有碰撞器、角色控制器和这个脚本的相机。当我进入游戏时，昆虫中的 MouseX 值发生了变化，但相机本身似乎被锁定了，我只能上下移动它。这只是主要代码的一小部分，但我认为它包含的内容足以说明问题。

[SerializeField]
private Camera m_Camera;
[SerializeField]
private CharacterController m_CharacterController;

[SerializeField]
private float m_MouseX;
[SerializeField]
private float m_MouseY;

 void Update()
{
    Rotate();
    Movement();
}

private void Rotate()
{
    // Receive mouse input and modifies
    m_MouseX += Input.GetAxis("Mouse X") * m_LookSensitivity;
    m_MouseY += Input.GetAxis("Mouse Y") * m_LookSensitivity;

    // Keep mouseY between -90 and +90
    m_MouseY = Mathf.Clamp(m_MouseY, -90.0f, 90.0f);

    // Rotate the player object around the y-axis
    transform.localRotation = Quaternion.Euler(Vector3.up * m_MouseX);
    // Rotate the camera around the x-axis
    m_Camera.transform.localRotation = Quaternion.Euler(Vector3.left * m_MouseY);
}

Answer 1

如果你使用transform.Rotate()方法而不是修改四元数来旋转你会更好，例如：

private void Rotate()
{
    // Receive mouse input and modifies
    m_MouseX += Input.GetAxis("Mouse X") * m_LookSensitivity;
    m_MouseY += Input.GetAxis("Mouse Y") * m_LookSensitivity;

    // Rotate the player object around the y-axis
    transform.Rotate(Vector3.up * m_MouseX);

    // Rotate the camera around the x-axis
    m_Camera.transform.Rotate(Vector3.left * m_MouseY);
}

如果您想将相机的最大角度限制在 (-90, 90)，您可以将 m_MouseY 累积在另一个变量上，并且仅当该变量位于正确的 inverval 范围内时，才可以单向旋转 (+/-) ，例如：

totalY += m_MouseY;
if (totalY < 90 && m_MouseY > 0)
   m_Camera.transform.Rotate(Vector3.left * m_MouseY);
if (totalY > -90 && m_MouseY < 0)
   m_Camera.transform.Rotate(Vector3.left * m_MouseY);
