# 资源更新
2022-04-12 19:36:18 +08:00
**获取资源版本**
对于联机运行模式,在更新补丁清单之前,需要获取一个资源版本号。
该资源版本号可以通过YooAssets提供的接口来更新也可以通过HTTP访问游戏服务器来获取。

````c#
private IEnumerator UpdateStaticVersion()
{
UpdateStaticVersionOperation operation = YooAssets.UpdateStaticVersionAsync();
yield return operation;
2022-03-10 16:55:12 +08:00
2022-04-12 19:36:18 +08:00
if (operation.Status == EOperationStatus.Succeed)
{
//更新成功
int resourceVersion = operation.ResourceVersion;
Debug.Log($"Update resource Version : {resourceVersion}");
}
else
{
//更新失败
Debug.LogError(operation.Error);

**补丁包下载**
在补丁清单更新完毕后,就可以更新资源文件了。
根据产品需求,可以选择更新全部资源,或者只更新部分资源。
补丁包下载接口:

- YooAssets.CreatePatchDownloader(int downloadingMaxNumber, int failedTryAgain)
用于下载更新当前资源版本所有的资源包文件。
- YooAssets.CreatePatchDownloader(string[] tags, int downloadingMaxNumber, int failedTryAgain)
用于下载更新资源标签指定的资源包文件。
- YooAssets.CreateBundleDownloader(string[] locations, int downloadingMaxNumber, int failedTryAgain)
用于下载更新指定的资源列表依赖的资源包文件。

{
int downloadingMaxNum = 10;
int failedTryAgain = 3;
