如何在Unity中通过脚本旋转播放器对象

Question

I have a game on Unity3d and I want to rotate player object via script:

Camera.main.transform.Rotate(0, 10, 0);

I can't rotate player object, so I try to rotate it's child object with camera component. And I can do it only when comment 2 strings in the standart script MouseLook.cs :

[Serializable]
public class MouseLook
{
    // Variables ..

    private Quaternion m_CharacterTargetRot;
    private Quaternion m_CameraTargetRot;

    public void Init(Transform character, Transform camera)
    {
        m_CharacterTargetRot = character.localRotation;
        m_CameraTargetRot = camera.localRotation;
    }

    public void LookRotation(Transform character, Transform camera)
    {
        float yRot = CrossPlatformInputManager.GetAxis("Mouse X") * XSensitivity;
        float xRot = CrossPlatformInputManager.GetAxis("Mouse Y") * YSensitivity;

        m_CharacterTargetRot *= Quaternion.Euler (0f, yRot, 0f);
        m_CameraTargetRot *= Quaternion.Euler (-xRot, 0f, 0f);

        if(clampVerticalRotation)
            m_CameraTargetRot = ClampRotationAroundXAxis (m_CameraTargetRot);

        if(smooth)
        {
            character.localRotation = Quaternion.Slerp (character.localRotation, m_CharacterTargetRot,
                smoothTime * Time.deltaTime);
            camera.localRotation = Quaternion.Slerp (camera.localRotation, m_CameraTargetRot,
                smoothTime * Time.deltaTime);
        }
        else
        {
            //character.localRotation = m_CharacterTargetRot; // move y axe
            //camera.localRotation = m_CameraTargetRot;       // move x axe
        }
    }      
}

But when I comment it, my mouse don't react, when I move it. How can I solve it?

Answer 1

Simply add a public variable to manage an additionnal angle you can change when you want, and tweek a little the LookRotation function :

 public float myAngle = 0 ;

public void LookRotation(Transform character, Transform camera)
{
    float yRot = CrossPlatformInputManager.GetAxis("Mouse X") * XSensitivity;
    float xRot = CrossPlatformInputManager.GetAxis("Mouse Y") * YSensitivity;

    // Add your angle here
    m_CharacterTargetRot *= Quaternion.Euler (0f, yRot + myAngle, 0f);
    m_CameraTargetRot *= Quaternion.Euler (-xRot, 0f, 0f);

    if(clampVerticalRotation)
        m_CameraTargetRot = ClampRotationAroundXAxis (m_CameraTargetRot);

    if(smooth)
    {
        character.localRotation = Quaternion.Slerp (character.localRotation, m_CharacterTargetRot,
            smoothTime * Time.deltaTime);
        camera.localRotation = Quaternion.Slerp (camera.localRotation, m_CameraTargetRot,
            smoothTime * Time.deltaTime);
    }
    else
    {
        character.localRotation = m_CharacterTargetRot; // move y axe
        camera.localRotation = m_CameraTargetRot;       // move x axe
    }
}

And in the code used to rotate the camera :

MouseLook mouseLook = gameObjectHoldingMouseLook.GetComponent<MouseLook>() ;
mouseLook.myAngle += 10 ;
