| url | The nominal (pre-redirect) URL at which the asset bundle is located. |
| crc | A checksum to compare to the downloaded data for integrity checking, or zero to skip integrity checking. |
Standard constructor for non-cached asset bundles.
This constructor will bypass the caching system and simply download the AssetBundle from url.
If the crc argument is non-zero, then the crc argument will be compared to the checksum of the downloaded data. If the CRCs do not match, an error will be logged, the asset bundle will not be loaded, and assetBundle will return null.
If you do not wish to use CRC integrity checking, pass zero as the crc argument.

public class Example : MonoBehaviour { IEnumerator Start() { string url = "https://website.com/assetbundle"; using (var uwr = new UnityWebRequest(url, UnityWebRequest.kHttpVerbGET)) { uwr.downloadHandler = new DownloadHandlerAssetBundle(url, 0); yield return uwr.SendWebRequest(); AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(uwr); } } }
| url | The nominal (pre-redirect) URL at which the asset bundle is located. |
| crc | A checksum to compare to the downloaded data for integrity checking, or zero to skip integrity checking. |
| version | Current version number of the asset bundle at url. Increment to redownload. |
Simple versioned constructor. Caches downloaded asset bundles.
When this constructor is used, the DownloadHandlerAssetBundle will first check to see if there is a cached AssetBundle from url.
If there is no cached asset bundle, or if the cached asset bundle's version matches the version argument, then the system will skip downloading the asset bundle and instead load it from the cache.
If there is a cached asset bundle, but the cached bundle's version does not match the version argument, then the system will re-download the asset bundle from url.
If the crc argument is non-zero, then the crc argument will be compared to the checksum of the downloaded data. If the CRCs do not match, an error will be logged, the asset bundle will not be loaded, and assetBundle will return null.
If you do not wish to use CRC integrity checking, pass zero as the crc argument.
| url | The nominal (pre-redirect) URL at which the asset bundle is located. |
| crc | A checksum to compare to the downloaded data for integrity checking, or zero to skip integrity checking. |
| hash | A hash object defining the version of the asset bundle. |
Versioned constructor. Caches downloaded asset bundles.
When this constructor is used, the DownloadHandlerAssetBundle will first check to see if there is a cached AssetBundle from url.
If there is no cached asset bundle, or if the cached asset bundle's hash matches the hash argument, then the system will skip downloading the asset bundle and instead load it from the cache.
If there is a cached asset bundle, but the cached bundle's hash does not match the hash argument, then the system will re-download the asset bundle from url.
If the crc argument is non-zero, then the crc argument will be compared to the checksum of the downloaded data. If the CRCs do not match, an error will be logged, the asset bundle will not be loaded, and assetBundle will return null.
If you do not wish to use CRC integrity checking, pass zero as the crc argument.
