Unity 5.X扩展编辑器之打包assetbundle

5.x的assetbundle与4.x以及之前的版本有些不同，不过本质是一样的，只不过5.x打包assetbundle更为简单和人性化了，总体来说只需要三个步骤：
//这里是一个资源包数组，其中每一个资源包又可以包含多个小资源，所以一般情况下一个资源包就足够了
AssetBundleBuild[] _ABbuild = new AssetBundleBuild[1];
第二步：给资源命名以及指定需要打包的资源
//资源包的名称
_ABbuild[0].assetBundleName = "打包assetbundle出来之后的文件名";
//资源包下的资源名称，一个资源包可以包含多个资源，资源由从Assets开始的路径组成且包含自身后缀名
string[] _allassetname = new string[3];
_allassetname[0] = "Assets/1.png";
_allassetname[1] = "Assets/2.prefab";
_allassetname[2] = "Assets/3.FBX";
_ABbuild[0].assetNames = _allassetname;
第三步：开始打包
//打包到路径E:/test/mytest
BuildPipeline.BuildAssetBundles("E:/test/mytest", _ABbuild);
将之封装成扩展编辑器之后，把如下脚本放在Editor文件夹内：
using UnityEngine;
using UnityEditor;
using System.Diagnostics;
using System.IO;
public class ExportAssetBundles : EditorWindow
{
[@MenuItem("AssetBundles/Build AssetBundles")]
static void main()
{
EditorWindow.GetWindow<ExportAssetBundles>(false,"AssetBundles");
}
private Vector2 scrollVec2;
private string rootPath = "Assets";
private string _assetBundleName = "";
private string _assetBundlePath = "Assets/StreamingAssets";
private int _assetBundleElementNum = 4;
private string[] _assetBundleElement = new string[4];
void OnGUI()
{
scrollVec2 = EditorGUILayout.BeginScrollView(scrollVec2, GUILayout.Width(position.width), GUILayout.Height(position.height));
EditorGUILayout.BeginHorizontal();
GUILayout.Label("资源包名称:");
_assetBundleName = EditorGUILayout.TextField(_assetBundleName);
if (GUILayout.Button("清空"))
EditorApplication.delayCall += Delete;
EditorGUILayout.EndHorizontal();
EditorGUILayout.BeginHorizontal();
GUILayout.Label("资源包路径:");
_assetBundlePath = EditorGUILayout.TextField(_assetBundlePath);
if (GUILayout.Button("浏览"))
EditorApplication.delayCall += Save;
EditorGUILayout.EndHorizontal();
EditorGUILayout.BeginHorizontal();
GUILayout.Label("资源包容量:");
_assetBundleElementNum = EditorGUILayout.IntField(_assetBundleElementNum);
if (GUILayout.Button("增加"))
EditorApplication.delayCall += Add;
EditorGUILayout.EndHorizontal();
if (_assetBundleElementNum > 0)
{
if (_assetBundleElement.Length != _assetBundleElementNum)
{
string[] temp = _assetBundleElement;
_assetBundleElement = new string[_assetBundleElementNum];
for (int i = 0; i < temp.Length; i++)
{
if (i < _assetBundleElement.Length)
_assetBundleElement[i] = temp[i];
}
}
for (int i = 0; i < _assetBundleElementNum; i++)
{
EditorGUILayout.BeginHorizontal();
GUILayout.Label("资源" + (i + 1) + ":");
_assetBundleElement[i] = EditorGUILayout.TextField(_assetBundleElement[i]);
if (GUILayout.Button("浏览"))
Browse(i);
EditorGUILayout.EndHorizontal();
}
}
if (GUILayout.Button("打包"))
{
if (_assetBundleName == "")
{
//打开一个通知栏
this.ShowNotification(new GUIContent("资源包名称不可为空"));
return;
}
if (_assetBundlePath == "C:/" || _assetBundlePath == "D:/" || _assetBundlePath == "E:/" || _assetBundlePath == "F:/")
{
//打开一个通知栏
this.ShowNotification(new GUIContent("资源包路径不可为根目录"));
return;
}
if (_assetBundleElementNum <= 0)
{

return;
}
for (int i = 0; i < _assetBundleElement.Length; i++)
{
if (_assetBundleElement[i] == null || _assetBundleElement[i] == "")
{
//打开一个通知栏
this.ShowNotification(new GUIContent("资源"+(i+1)+"路径为空"));
return;
}
}
EditorApplication.delayCall += Build;
}
EditorGUILayout.EndScrollView();
