Question

我在Unity3D中使用FPS，我只想要Pitch和Yaw。一些移动后，我的鼠标外观脚本开始围绕z轴旋转（即ROLL）。如何制止？

这是我用于鼠标外观的脚本。

using UnityEngine;
using System.Collections;

public class MouseLooking : MonoBehaviour
{

    float sensitivityX = 10f;
    float sensitivityY = 10f;
    public float minimumX = -360;
    public float maximumX = 360;
    public float minimumY = -60;
    public float maximumY = 60;
    public float delayMouse = 3;
    public float noiseX = 0.1f;
    public float noiseY = 0.1f;
    public bool Noise;

    private float rotationX = 0;
    private float rotationY = 0;
    private float rotationXtemp = 0;
    private float rotationYtemp = 0;

    private float noisedeltaX;
    private float noisedeltaY;
    private float stunY;
    private float breathHolderValtarget = 1;
    private float breathHolderVal = 1;
    private TouchScreenVal touch;


    void Start ()
    {
            if (rigidbody)
                    rigidbody.freezeRotation = true;
            originalRotation = transform.localRotation;

            sensitivityX = sensitivityY = 10;

            touch = new TouchScreenVal (new Rect (0, 0, Screen.width, Screen.height));

    }



    void Update ()
    {
            sensitivityY = sensitivityX;
            //      Screen.lockCursor = true;

            stunY += (0 - stunY) / 20f;

            if (Noise) {
                    noisedeltaX += ((((Mathf.Cos (Time.time) * Random.Range (-10, 10) / 5f) * noiseX) - noisedeltaX) / 100);

您不能使用浮点数来存储x和y旋转，您需要将它全部存储在四元数中。因此，当您从鼠标输入更新时，将其直接添加到四元数。

例如，请参阅Quaternion rotation without Euler angles。
