一、UnityEditor
1.[MenuItem(名字)]
声明在一个函数上方，告知编译器给Unity3D编辑器添加一个菜单项，并且当点击该菜单项的时候调用该函数。
例如：%t是ctrl+T
//在Asset窗口右键添加方法，可以具体到路径
[MenuItem("Assets/在Project目录里右键1")]
private static void Assets_right_btn1()
｛
Debug.Log("在Project目录里右键1");
｝
//Hierarchy添加方法
[MenuItem(("GameObject/保存当前场景"), false, -1)]
2.Selection类
获取当前选中的文件。
3.[ContextMenu("XXX")]
为继承自MonoBehaviour的类的右键添加方法
4.AddComponentMenu
[AddComponentMenu("组件菜单/ComponentMenu")]
public class ComponentMenuTest : MonoBehaviour {
}5.GUILayout.Button("打开")
EditorGUILayout.LabelField("。。。。。。。。");
string name = EditorGUILayout.TextField("", GUILayout.Width(150), GUILayout.Height(20));
二、部分文件操作方法：
1.EditorWindow通过拖拽获取文件夹或者文件路径
#region 拖拽相关
Rect rect4 = EditorGUILayout.GetControlRect();
//将上面的框作为文本输入框
selectPath = EditorGUI.TextField(rect4, selectPath);
//subPath = EditorGUILayout.TextField(subPath);
//如果鼠标正在拖拽中或拖拽结束时，并且鼠标所在的位置在文本输入框内
if ((Event.current.type == EventType.DragUpdated || Event.current.type == EventType.DragExited) && rect4.Contains(Event.current.mousePosition))
{
DragAndDrop.visualMode = DragAndDropVisualMode.Generic;
if (DragAndDrop.paths != null && DragAndDrop.paths.Length > 0)
{
selectPath = DragAndDrop.paths[0];
}
}
#endregion
2.反序列化
public static Object GetObjectFromBytes(byte[] datas)
{
if (datas == null || datas.Length == 0)
return null;
BinaryFormatter bf = new BinaryFormatter();
using (MemoryStream stream = new MemoryStream(datas, 0, datas.Length))
{
Object obj = bf.Deserialize(stream) as Object;
stream.Dispose();
return obj;
}
}
3.保存到文件
bool SaveLocalFile(string path, byte[] data)
{
if (File.Exists(path))
File.Delete(path);
using (FileStream fs = new FileStream(path, FileMode.CreateNew))
{
if (fs == null)
return false;
fs.Write(data, 0, data.Length);
AssetDatabase.Refresh();
AssetDatabase.ImportAsset(path, ImportAssetOptions.ForceUpdate);
return true;
}
}
4.取文件
public byte[] GetLocalFile(string path)
{
if (File.Exists(path) == false)
return null;
using (FileStream fs = new FileStream(path, FileMode.Open))
{
if (fs == null || fs.Length == 0)
return null;
byte[] data = new byte[fs.Length];
fs.Read(data, 0, data.Length);
return data;
}
}
5.调用windows系统dialog 选择文件夹
