目录
（3）.在OnGUI()中draw出来一些按钮/label 等
1.工具制作的起因
现在大多数公司做游戏为了压缩时间和成本，基本都会直接拿以前或者是直接从网上找一些开源的游戏代码，在此基础上进行二次创作，在这种代码环境下做一些新的逻辑，难免会遇到一些困难，比如：
我在开发过程中需要加一个新的layer层来完成我的新代码逻辑 ，但是发现旧的代码已经把全部的layer用掉了我们都知道layer层是没办法添加的。
不明白为什么不能添加的同学可以看下：
因此我就只能写一个查找预制体layer的工具 以此来找到使用次数最少的layer层，以此来减轻更改layer层对原逻辑的影响。
2.工具的制作
（1）.首先在Assets->Editor 目录下创建脚本
（2）.创建一个工具窗口
代码如下：
public class ReadOrWriteLayer : EditorWindow{
static string checkPath;
[MenuItem("SelfTools / 打开layer查找窗口")]
public static void OpenWindow() {
??????? ReadOrWriteLayer readOrWriteLayer = EditorWindow.GetWindow<ReadOrWriteLayer>();
??????? readOrWriteLayer.Show();
??????? checkPath = "Assets";
??? }
}
其中 ：ReadOrWriteLayer 是创建类名
??????????? checkPath 是查找的路径
注意：我们的类要继承EditorWindow
（3）.在OnGUI()中draw出来一些按钮/label 等
?
代码如下：?
????????GUILayout.BeginHorizontal();
??????? checkPath = EditorGUILayout.TextField("输入当前查找/替换的路径:", checkPath);
??????? GUILayout.EndHorizontal();
??????? GUILayout.Space(10);
动态修改checkPath 即 修改查找或者替换的路径?
????????GUILayout.BeginHorizontal();
??????? chechLayer = EditorGUILayout.TextField("输入当前查找的layer层:", chechLayer);
??????? GUILayout.EndHorizontal();
??????? GUILayout.Space(10);??????? GUILayout.BeginHorizontal();
??????? replaceLayer = EditorGUILayout.TextField("输入替换的layer层:", replaceLayer);
??????? GUILayout.EndHorizontal();
??????? GUILayout.Space(10);
分别输入要查找的layer层和要替换的layer层其中 chechLayer是要查找的layer层 replaceLayer是要替换成的layer层?
GUILayout.BeginHorizontal();
??????? if(GUILayout.Button("开始查找", "buttonleft", GUILayout.Width(250),??? ????????GUILayout.Height(50))) {
??????????? if(!int.TryParse(chechLayer, out layer)) {
??????????????? chechLayer = "";
??????????? } else
??????????????? CheckAllGameObjectByLayer();
??????? }GUILayout.EndHorizontal();
GUILayout.Space(10);?
添加按钮
点击后执行查找方法 CheckAllGameObjectByLayer(); 检查输出所有查询的layer预制体路径和子节点路径
GUILayout.BeginHorizontal();
??????? if(GUILayout.Button("开始替换", "buttonleft", GUILayout.Width(250), GUILayout.Height(50))) {
??????????? if(!int.TryParse(chechLayer, out layer) || !int.TryParse(replaceLayer, out replacelayer)) {
??????????????? chechLayer = "";
??????????? } else
??????????????? ReplaceAllGameObjectLayer();
??????? }
??????? GUILayout.EndHorizontal();
??????? GUILayout.Space(10);
添加按钮
点击后执行查找方法 ReplaceAllGameObjectLayer(); 替换所有查询的layer层为替换layer层
（4）.查询方法
private void CheckAllGameObjectByLayer() {
//写入进度条的当前值
startVal = 0f;
//输出文件保存路径
savePath = Application.dataPath + "/Editor/LayerSetting.text";
if(File.Exists(savePath))
File.Delete(savePath);
string allStr = "";
//查找checkPath路径下的所有文件路径
string[] allPath = Directory.GetFiles(checkPath, "*.prefab", SearchOption.AllDirectories);
maxValue = allPath.Length;
if(allPath.Length > 0) CreateFile();
//把预制体和预制体里面的子物体写入到文件LayerSetting.text中
using(FileStream fs = new FileStream(savePath, FileMode.Open)) {
StreamWriter sw = new StreamWriter(new BufferedStream(fs), Encoding.UTF8);
for(int i = 0; i < allPath.Length; i++) {
if(File.Exists(allPath[i])) {
//通过路径获取游戏obj
GameObject obj = AssetDatabase.LoadAssetAtPath<GameObject>(allPath[i]);
if (obj == null) continue;
if(obj.layer == layer) {
allStr += string.Format("{0}\r\n", allPath[i]);
IterationAllGameObject(obj.transform, obj.name, ref allStr);
allStr += "\r\n";
} else {
IterationAllGameObject(obj.transform, obj.name, ref allStr);
}
}
startVal = i + 1;
//刷新当前读取进度
float slider = (float)startVal / maxValue;
//参数1 为标题，参数2为提示，参数3为 进度百分比 0~1 之间
EditorUtility.DisplayProgressBar("Loading", "写入中......", slider);
//写入文件
sw.Write(allStr);
allStr = "";
}
sw.Close();
fs.Close();
fs.Dispose();
}
//全部结束关闭进度条
EditorUtility.ClearProgressBar();
}
//如果保存文件不存在 创建一个
private static void CreateFile() {
if(!File.Exists(savePath)) {
FileStream file = new FileStream(savePath, FileMode.Create);
file.Dispose();
}
}
//迭代obj的所有子物体
private static void IterationAllGameObject(Transform obj, string path, ref string allStr, bool writeLayer = false) {
for(int i = 0; i < obj.childCount; i++) {
GameObject child = obj.GetChild(i).gameObject;
string realPath = path;
if(!writeLayer) {
if(child.layer == layer) {
realPath += string.Format("->{0}\r\n", child.name);
allStr += realPath;
}
} else {
realPath += string.Format("->{0} ::Layer -> {1}\r\n", child.name, child.layer);
allStr += realPath;
}
string namePath = string.Format("{0} ->{1}", path, child.name);
IterationAllGameObject(obj.GetChild(i), namePath, ref allStr, writeLayer);
}
}（5）.替换方法
private void ReplaceAllGameObjectLayer(bool checkLayer = true) {
startVal = 0f;
string[] allPath = Directory.GetFiles(checkPath, "*.prefab", SearchOption.AllDirectories);
maxValue = allPath.Length;
for(int i = 0; i < allPath.Length; i++) {
if(File.Exists(allPath[i])) {
GameObject obj = AssetDatabase.LoadAssetAtPath<GameObject>(allPath[i]);
if (obj == null) continue;
if(obj.layer == layer) {
obj.layer = replacelayer;
} else if(!checkLayer) {
obj.layer = replacelayer;
}
IterationReplace(obj.transform, checkLayer);
}
startVal = i + 1;
float slider = (float)startVal / maxValue;
//参数1 为标题，参数2为提示，参数3为 进度百分比 0~1 之间
EditorUtility.DisplayProgressBar("Loading", "写入中......", slider);
}
EditorUtility.ClearProgressBar();
//保存全部修改
AssetDatabase.SaveAssets();
}
private static void IterationReplace(Transform obj, bool checkLayer = true) {
for(int i = 0; i < obj.childCount; i++) {
GameObject child = obj.GetChild(i).gameObject;
if(child.layer == layer) {
child.layer = replacelayer;
} else if(!checkLayer)
child.layer = replacelayer;
IterationReplace(obj.GetChild(i), checkLayer);
}
}
至此一个完整的layer层查询/替换工具诞生了
3.效果展示：
这个文件里就是查询的layer层的所有预制体的路径信息
点击替换 输入替换layer层就可以把文件中的所有预制体都替换掉
4.拓展：
由于每次都要手动填写查询目录 我觉得十分烦 想到unity有一个选中逻辑 于是添加了一条鼠标选中后路径更新
代码如下：
??? static bool isRun = false;
??? bool toggle;?? ?GUILayout.BeginHorizontal();
??????? toggle = EditorGUILayout.BeginToggleGroup("选择路径", toggle);
??????? if(Selection.assetGUIDs.Length > 0 && !isRun && toggle) {
??????????? string selectPath = AssetDatabase.GUIDToAssetPath(Selection.assetGUIDs[0]);
??????????? checkPath = selectPath;
??????? }
??????? EditorGUILayout.EndToggleGroup();
??????? GUILayout.EndHorizontal();
??????? GUILayout.Space(10);
另外在替换或者查询中关闭isRun
效果如下：
勾选选择路径之后 查找/替换路径会自动更换成鼠标选择的路径
注：鼠标选择之后需要移到此面板 此面板才会动态更新路径
