Unity对象旋转功能

      今天上的是一个我们会经常使用的功能---物体旋转（包括UI对象和游戏对象）。使用方法很简单，将脚本挂在目标对象上，在Inspector面板上添加和选中具体参数即可，如下图所示：

      下面上功能代码；还有一份编辑器代码。

using UnityEngine;/// <summary>/// 直接挂在需要旋转的对象上/// 提供旋转的功能/// </summary>public class RotateFunction : MonoBehaviour{    /// <summary>    /// 旋转模式    /// </summary>    public RotateMode MyRotateMode;    /// <summary>    /// 旋转轴    /// </summary>    public RotateAxle MyRotate_Axle;    /// <summary>    /// 绕某目标旋转时的目标对象    /// </summary>    public GameObject RotateTargetObj;    Transform mytransform;    void Start()    {        mytransform = this.transform;    }    //旋转的速度    public float RotateSpeed = 360f;    void FixedUpdate()    {        //自转        RotateAroundSelf();        //绕某点转        RotateAroundTarget();    }    /// <summary>    /// 自传    /// </summary>    void RotateAroundSelf()    {        if (MyRotateMode == RotateMode.Rotate_Self)        {            switch (MyRotate_Axle)            {                case RotateAxle.X:                    mytransform.Rotate(new Vector3(1f, 0, 0) * RotateSpeed * Time.deltaTime, Space.Self);                    break;                case RotateAxle.Y:                    mytransform.Rotate(new Vector3(0, 1f, 0) * RotateSpeed * Time.deltaTime, Space.Self);                    break;                case RotateAxle.Z:                    mytransform.Rotate(new Vector3(0, 0, 1f) * RotateSpeed * Time.deltaTime, Space.Self);                    break;            }        }    }    /// <summary>    /// 绕目标旋转    /// </summary>    void RotateAroundTarget()    {        if (MyRotateMode == RotateMode.Rotate_Target && RotateTargetObj != null)        {            switch (MyRotate_Axle)            {                case RotateAxle.X:                    mytransform.RotateAround(RotateTargetObj.transform.position, Vector3.right, RotateSpeed * Time.deltaTime);                    break;                case RotateAxle.Y:                    mytransform.RotateAround(RotateTargetObj.transform.position, Vector3.up, RotateSpeed * Time.deltaTime);                    break;                case RotateAxle.Z:                    mytransform.RotateAround(RotateTargetObj.transform.position, Vector3.forward, RotateSpeed * Time.deltaTime);                    break;            }        }    }}

下面上功能编辑器脚本

using UnityEngine;#if UNITY_EDITORusing UnityEditor;[CustomEditor(typeof(RotateFunction))]public class RotateFunctionEditor : Editor{    public RotateFunction m_RotateFunction = null;    public void OnEnable()    {        m_RotateFunction = (RotateFunction)target;    }    public override void OnInspectorGUI()    {        bool isChanged = false;        //绘制MyRotateMode        RotateMode oldMyRotateMode = m_RotateFunction.MyRotateMode;        m_RotateFunction.MyRotateMode = (RotateMode)EditorGUILayout.EnumPopup("MyRotateMode", m_RotateFunction.MyRotateMode);        if (oldMyRotateMode != m_RotateFunction.MyRotateMode)            isChanged = true;        //根据选择的RotateMode来确定RotateTarget        if (m_RotateFunction.MyRotateMode == RotateMode.Rotate_Target)        {            GameObject oidObj = m_RotateFunction.RotateTargetObj;            m_RotateFunction.RotateTargetObj = (GameObject)EditorGUILayout.ObjectField("RotateTargetObj", m_RotateFunction.RotateTargetObj, typeof(GameObject), true);            if (oidObj != m_RotateFunction.RotateTargetObj)                isChanged = true;        }        //绘制MyRotate_Axle        RotateAxle oldMyRotate_Axle = m_RotateFunction.MyRotate_Axle;        m_RotateFunction.MyRotate_Axle = (RotateAxle)EditorGUILayout.EnumPopup("MyRotate_Axle", m_RotateFunction.MyRotate_Axle);        if (oldMyRotate_Axle != m_RotateFunction.MyRotate_Axle)            isChanged = true;        //绘制Rotate Speed        float oldRotateSpeed = m_RotateFunction.RotateSpeed;        m_RotateFunction.RotateSpeed = EditorGUILayout.FloatField("Rotate Speed", m_RotateFunction.RotateSpeed);        if (oldRotateSpeed != m_RotateFunction.RotateSpeed)            isChanged = true;        if (isChanged)            EditorUtility.SetDirty(m_RotateFunction);    }}#endif

       其实功能脚本倒没啥技术含量，值得初学者看看的是第二份是功能的编辑器脚本！
