Unity Editor 编写unity插件类

在unity写了一个编辑类，基于iTweenpath插件，为了更方便的操作iTweenpath，顺便练习UnityEditor的操作，写了一个CreateiTweenPath，放在Editor文件夹中。

using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityEditor;

public class CreateiTweenPath :EditorWindow {     [MenuItem("GameObject/CreatePath")]     static void main()     {         EditorWindow.GetWindow("CreatePath");     }

    private Vector2 scrollVec2;     private Transform target=null;     private string pathName="new path 1";     private int nodeCount=2;     private int speed=7;     private Vector3[] nodes = new Vector3[]{Vector3.zero,new Vector3(10,0,0)};     private PathLoopType loopType=PathLoopType.once;     private Color pathColor = Color.cyan;

    void OnGUI()     {         scrollVec2=GUILayout.BeginScrollView(scrollVec2);         target=EditorGUILayout.ObjectField("移动物体:", target, typeof(Transform)) as Transform;         GUILayout.BeginHorizontal();         GUILayout.Label("路径名称:");         pathName=EditorGUILayout.TextField(pathName);         GUILayout.Label("速度:");         speed=EditorGUILayout.IntField(speed);         GUILayout.EndHorizontal();         loopType = (PathLoopType)EditorGUILayout.EnumPopup("循环类型:", loopType);         pathColor = EditorGUILayout.ColorField("路径颜色:", pathColor);         GUILayout.BeginHorizontal();         GUILayout.Label("路径节点数:");         nodeCount = EditorGUILayout.IntField(nodeCount);         GUILayout.EndHorizontal();         if (nodeCount > 0)         {             if (nodes.Length != nodeCount)             {                 Vector3[] temp = nodes;                 nodes = new Vector3[nodeCount];                 for (int i = 0; i < temp.Length; i++)                 {                     if (i < nodes.Length)                         nodes[i] = temp[i];                 }             }             for (int i = 0; i < nodeCount; i++)                 nodes[i] = EditorGUILayout.Vector3Field("节点 "+(i+1)+":",nodes[i]);         }         if (GUILayout.Button("创建"))             CreatePath();         GUILayout.EndScrollView();     }

    void CreatePath()     {         if (target == null)         {             EditorUtility.DisplayDialog("Error", "移动物体不能为null", "OK");             return;         }         if (pathName == null || pathName == "")             return;         GameObject go = new GameObject();         go.name = "iTweenPath_"+target.name;         go.AddComponent();         go.GetComponent().initialized = true;         go.GetComponent().pathName = pathName;         go.GetComponent().pathColor = pathColor;         go.GetComponent().nodeCount = nodeCount;         List listNodes = new List();         for (int i = 0; i < nodes.Length; i++)             listNodes.Add(nodes[i]);         go.GetComponent().nodes = listNodes;

        go.AddComponent();         go.GetComponent().target = target;         go.GetComponent().pathName = pathName;         go.GetComponent().speed = speed;         go.GetComponent().loopType = loopType;

        EditorWindow.GetWindow().Close();     } }

点击GameObject/CreatePath，显示一下界面，点击即可创建路径
