协程下载AssetBundle方法
void Start()
{
IEnumerator LoadResourceCorotine(string resName, string filePath)
{
UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(@"http://localhost/AssetBundles/" + filePath);
yield return request.SendWebRequest();
// AssetBundle ab = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;
AssetBundle ab = DownloadHandlerAssetBundle.GetContent(request);
GameObject gameObject = ab.LoadAsset<GameObject>(resName);
}
}
本地加载方式
AssetBundle.LoadFromFile
AssetBundle.LoadFromMemoryAsync
通过AssetBundleManifest得到某个包的依赖
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class LoadFromFileExample : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
AssetBundle ab = AssetBundle.LoadFromFile("AssetBundles/cube.unity3d");
AssetBundleManifest manifest = ab.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
//通过AssetBundleManifest获取所有AssetBundle名字
foreach (var name in manifest.GetAllAssetBundles())
{
print(name);
}
//获取cube依赖的AssetBundle名字
string[] strs=manifest.GetAllDependencies("cube.unity3d");
//加载依赖的包
foreach (var name in strs)
{
print(name);
AssetBundle.LoadFromFile("AssetBundles/"+name);
}
GameObject cube = ab.LoadAsset<GameObject>("Cube");
Instantiate(cube);
//卸载AssetBundle true全部卸载,flase卸载不相关的
ab.Unload(true);
}
void Update()
{
}
}
