CloseHelpers for downloading asset bundles using UnityWebRequest.
using UnityEngine; using UnityEngine.Networking; using System.Threading.Tasks;
// This example demonstrates how to load an AssetBundle asynchronously. public class AssetBundleLoader : MonoBehaviour { // Load an AssetBundle from a URL asynchronously public async Task<AssetBundle> LoadAssetBundleAsync(string url) { using (UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(url)) { var operation = request.SendWebRequest();
while (!operation.isDone) await Task.Yield();
if (request.result != UnityWebRequest.Result.Success) { Debug.LogError($"Failed to load AssetBundle: {request.error}"); return null; }
return DownloadHandlerAssetBundle.GetContent(request); } }
// Example usage public async void LoadBundle() { // Replace this with your own URL. // You can use python -m http.server to serve files locally. // Remember to first build the AssetBundle string bundleUrl = "http://example.com/mybundle.assetbundle"; AssetBundle bundle = await LoadAssetBundleAsync(bundleUrl);
if (bundle != null) { // Load assets from bundle GameObject prefab = bundle.LoadAsset<GameObject>("MyPrefab"); Instantiate(prefab);
// Remember to unload when done bundle.Unload(false); } } }
