做系统网站赚钱什么是搜索引擎优化
1.新建两个预制体：
Cube1：GameObject
Material1：Material
Cube1使用了Material1材质
之后设置打包配置
Cube1的打包配置为custom.ab
Material1的打包配置为mat.ab
2.在Asset文件夹下创建Editor文件夹，并在Editor下创建BuildBundles.cs
using System.IO;
using UnityEditor;
using UnityEngine;
public class BuildBundles : Editor
{
[MenuItem("Custom/BuildBundles")]
static void BuildBundle()
{
//参数（打包路径、选项为None、使用平台）
BuildPipeline.BuildAssetBundles(Path.Combine(Application.dataPath + "/AssetBundle"), BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64);
}
}
创建完成后，可在工具栏看到Custom/BuildBundles选项
3.将预制体打包成AssetBundle文件
在Asset文件夹下创建AssetBundle文件夹
之后点击工具栏的Custom/BuildBundles，AssetBundle文件被生成至AssetBundle文件夹中
AssetBundle是本次生成的所有的AssetBundle文件的配置文件，其中的AssetBundleManifest属性描述了文件的信息和依赖关系
custom.ab为Cube1的配置信息，上面也说明了其与mat.ab有依赖关系
以下是mat.ab的配置信息
4.获取AssetBundle文件并编译至场景中
新建AssetBundleTest.cs，并挂载至场景内任何一物体中
using System.Collections;
using System.IO;
using UnityEngine;
using UnityEngine.Networking;
public class AssetBundleTest : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
//loadMat();//同步加载（依赖）
//loadCube();//同步加载（Cube）
StartCoroutine(LoadCubeAsync());//异步加载
//StartCoroutine(LoadCubeWWW());//从服务端获取
}
//加载依赖（同步）
void loadMat()
{
//加载依赖
//读取AssetBundle下名称为AssetBundle的文件
string path = Application.dataPath + "/AssetBundle/AssetBundle";
AssetBundle assetBundle = AssetBundle.LoadFromFile(path);
//加载该文件夹里的配置信息
AssetBundleManifest assetBundleManifest = assetBundle.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
//加载名为custom.ab的文件的所有依赖并转为字符串数组
string[] strs = assetBundleManifest.GetAllDependencies("custom.ab");
foreach(string name in strs)
{
//加载出需要用到的AssetBundle文件
AssetBundle.LoadFromFile(Application.dataPath + "/AssetBundle/" + name);
}
}
//加载Cube（同步）
void loadCube()
{
string Cubepath = Path.Combine(Application.dataPath + "/AssetBundle/custom.ab");
AssetBundle ab = AssetBundle.LoadFromFile(Cubepath);
GameObject CubePre = ab.LoadAsset<GameObject>("Cube");
Instantiate(CubePre);
}
//异步加载Cube
private IEnumerator LoadCubeAsync()
{
//加载依赖
//读取AssetBundle下名称为AssetBundle的文件
string path1 = Application.dataPath + "/AssetBundle/AssetBundle";
AssetBundleCreateRequest assetBundle1 = AssetBundle.LoadFromFileAsync(path1);
yield return assetBundle1;
//加载该文件夹里的配置信息
AssetBundleManifest assetBundleManifest = assetBundle1.assetBundle.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
//加载名为custom.ab的文件的所有依赖并转为字符串数组
string[] strs = assetBundleManifest.GetAllDependencies("custom.ab");
foreach (string name in strs)
{
//加载出需要用到的AssetBundle文件
AssetBundle.LoadFromFile(Application.dataPath + "/AssetBundle/" + name);
}
//加载Cube
//读取custom.ab文件
string path = Application.dataPath + "/AssetBundle/custom.ab";
//string path4 = Path.Combine(Application.dataPath, "AssetBundle", "custom.ab");//使用Path.Combine拼接路径
AssetBundleCreateRequest assetBundleCreateRequest = AssetBundle.LoadFromFileAsync(path);
//异步等待加载完成
yield return assetBundleCreateRequest;
//加载完成，之后在场景中生成出来
AssetBundle assetBundle = assetBundleCreateRequest.assetBundle;
GameObject CubePre = assetBundle.LoadAsset<GameObject>("Cube1");
Instantiate(CubePre);
}
private IEnumerator LoadCubeWWW()
{
//从服务端获取AssetBundle文件
//获取路径并通过UnityWebRequest获取指定文件
string path1 = Path.Combine("http://192.168.0.102/web/custom.ab");
UnityWebRequest unityWebRequest = UnityWebRequest.Get(path1);
//等待文件获取完成
yield return unityWebRequest.SendWebRequest();
//加载完成
AssetBundle assetBundle = DownloadHandlerAssetBundle.GetContent(unityWebRequest);
GameObject CubePre = assetBundle.LoadAsset<GameObject>("Cube");
Instantiate(CubePre);
}
}
