首先需要打包一个预制体物体，该预制体需要更改后缀为.unity3d；
using UnityEditor;
using System.Collections;
using UnityEngine;
using System.IO;
using System.Collections.Generic;
public class QABEditor
{
[MenuItem("QFramework/AB/Build")]
public static void BuildAssetBundle()
{
// AB包输出路径
string outPath = Application.streamingAssetsPath + "/QAB";
// 检查路径是否存在
CheckDirAndCreate (outPath);
BuildPipeline.BuildAssetBundles (outPath, 0, EditorUserBuildSettings.activeBuildTarget);
// 刚创建的文件夹和目录能马上再Project视窗中出现
AssetDatabase.Refresh ();
}
/// <summary>
/// 判断路径是否存在,不存在则创建
/// </summary>
public static void CheckDirAndCreate(string dirPath)
{
if (!Directory.Exists (dirPath)) {
Directory.CreateDirectory (dirPath);
}
}
}
读取ab包；
using UnityEngine;
using System.Collections;
using System.IO;
public class QFramework : MonoBehaviour
{
public string busUnity; //ab包的名字 xxx.unity3d
public string busName; //生成物体的名字 xxx
public string tree1Unity;
public string tree1Name;
void Start()
{
StartCoroutine(GameInstanciate(busUnity, busName));
StartCoroutine(GameInstanciate(tree1Unity, tree1Name));
}
IEnumerator GameInstanciate(string unity, string name)
{
WWW www = new WWW("file:///" + Application.streamingAssetsPath + Path.DirectorySeparatorChar + "QAB" + Path.DirectorySeparatorChar + unity);
yield return www;
if (string.IsNullOrEmpty(www.error))
{
var go = www.assetBundle.LoadAsset<GameObject>(name);
Debug.Log(go.transform.position);
Instantiate(go);
//Instantiate(go).transform.SetParent(GameObject.Find("Tree").transform);
// Transform obj= Instantiate(go.transform,go.transform.position,Quaternion.identity,GameObject.Find("Tree").transform)as Transform;
//GameObject obj = Instantiate(go, GameObject.Find("Tree").transform);
// obj.transform.position = go.transform.position;
// obj.transform.rotation = go.transform.rotation;
}
else
{
Debug.LogError(www.error);
}
}
}
