# 资源更新
|
||
|
||
**更新补丁清单**
|
||
|
||
对于联机运行模式，在初始化资源系统之后，需要立刻更新资源清单。
|
||
|
||
在此之前，需要获取更新的资源版本号，一般通过HTTP访问游戏服务器来获取。
|
||
|
||
````c#
|
||
private IEnumerator UpdatePatchManifest()
|
||
{
|
||
int updateResourceVersion = 123;
|
||
int timeout = 30;
|
||
UpdateManifestOperation operation = YooAssets.UpdateManifestAsync(updateResourceVersion, timeout);
|
||
yield return operation;
|
||
|
||
if (operation.Status == EOperationStatus.Succeed)
|
||
{
|
||
//更新成功
|
||
}
|
||
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。
|
||
|
||
````c#
|
||
private PatchDownloader _downloader;
|
||
|

{

|
||
_downloader = YooAssets.CreateDLCDownloader(tags, 10, 3);
|
