Unity导包丢失tag值、layer值

来源：互联网发布：python service 编辑：程序博客网时间：2024/06/05 14:26

当一个项目打包为unityPackage后，再次导入其他项目后，项目里自定义的tag和layer会丢失，下面方法，在导入unitypackage包的时候自动把它的tag或者layer写进用户的项目里。将下面的脚本，随着资源一起打包，这样当别的工程导入该项目的unitypackage包时，程序会调用AddTag和AddLayer来添加，项目中可能已经添加了tag和layer，所以在添加前先做了判断。

下面代码只添加了一个tag和一个layer，修改添加N多个tag和layer

将该脚本放在工程下即可

using System;using System.Collections;using System.Reflection;using UnityEditor;using UnityEngine;public class NewBehaviourScript : AssetPostprocessor{    private static string[] myTags = { "aaaa", "bbbb", "cccc", "dddd"};    private static string[] myLayers = { "AAAA", "BBBB", "CCCC", "DDDD"};     static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths)    {        foreach (string s in importedAssets)        {            if (s.Equals("Assets/NewBehaviourScript.cs"))            {                foreach (string tag in myTags)                {                    AddTag(tag);                }                foreach (string layer in myLayers)                {                    AddLayer(layer);                }                     AddTag("self");<span style="font-family: Arial, Helvetica, sans-serif; font-size: 12px;">//增加一个叫self的tag</span>                AddLayer("self");<span style="font-family: Arial, Helvetica, sans-serif; font-size: 12px;">//增加一个叫ruoruo的layer</span>                return;            }        }    }    static void AddTag(string tag)    {        if (!isHasTag(tag))        {            SerializedObject tagManager = new SerializedObject(AssetDatabase.LoadAllAssetsAtPath("ProjectSettings/TagManager.asset")[0]);            SerializedProperty it = tagManager.GetIterator();            while (it.NextVisible(true))            {                if (it.name == "tags")                {                    for (int i = 0; i < it.arraySize; i++)                    {                        SerializedProperty dataPoint = it.GetArrayElementAtIndex(i);                        if (string.IsNullOrEmpty(dataPoint.stringValue))                        {                            dataPoint.stringValue = tag;                            tagManager.ApplyModifiedProperties();                            return;                        }                    }                }            }        }    }    static void AddLayer(string layer)    {        if (!isHasLayer(layer))        {            SerializedObject tagManager = new SerializedObject(AssetDatabase.LoadAllAssetsAtPath("ProjectSettings/TagManager.asset")[0]);            SerializedProperty it = tagManager.GetIterator();            while (it.NextVisible(true))            {                if (it.name.StartsWith("User Layer"))                {                    if (it.type == "string")                    {                        if (string.IsNullOrEmpty(it.stringValue))                        {                            it.stringValue = layer;                            tagManager.ApplyModifiedProperties();                            return;                        }                    }                }            }        }    }    static bool isHasTag(string tag)    {        for (int i = 0; i < UnityEditorInternal.InternalEditorUtility.tags.Length; i++)        {            if (UnityEditorInternal.InternalEditorUtility.tags[i].Contains(tag))                return true;        }        return false;    }    static bool isHasLayer(string layer)    {        for (int i = 0; i < UnityEditorInternal.InternalEditorUtility.layers.Length; i++)        {            if (UnityEditorInternal.InternalEditorUtility.layers[i].Contains(layer))                return true;        }        return false;    }}
