How to fetch the list of changed bundle address?

I want to load all changed bundles in loading scene. How do i fetch the list of changed bundle address, then download them?

 

Is this what you're trying to do?

Code (CSharp):

1. Addressables.CheckForCatalogUpdates().Completed += handle =>
2. {
3.     Addressables.DownloadDependenciesAsync(new List<object>(handle.Result), Addressables.MergeMode.Union);
4. };

 

But I don't want to load dependencies. I just want to load changed bundles.
Before Addressables, we can compare the new and old manifests in loading scene, know which bundles have changed, and download the new bundles，then enter main scene

 

Ah my bad, checked the docs, looks like the handle from

CheckForCatalogUpdates

actually contains the catalogs that can be updated. So you would run a

LoadContentCatalogAsync

for each catalog id, then

DownloadDependenciesAsync

on the keys.

This should do what you want, then you can await it before entering your main scene.

Code (CSharp):

1. async Task UpdateBundles()
2. {
3.     // Get catalog keys that can be updated.
4.     var catalogKeys = await Addressables.CheckForCatalogUpdates().Task;
5.     if (catalogKeys.Count == 0) return;
6.  
7.     // Update catalogs in parallel and wait for them all to complete.
8.     Task<IResourceLocator>[] catalogTasks = new Task<IResourceLocator>[catalogKeys.Count];
9.     for (int i = 0; i < catalogKeys.Count; ++i)
10.     {
11.         catalogTasks[i] = Addressables.LoadContentCatalogAsync(catalogKeys[i]).Task;
12.     }
13.     var locators = await Task.WhenAll(catalogTasks);
14.  
15.     // Combine all keys, then download dependencies and wait for them to complete. This will only download bundles we don't already have.
16.     HashSet<object> keys = new HashSet<object>(locators[0].Keys);
17.     for (int i = 1; i < locators.Length; ++i)
18.     {
19.         keys.UnionWith(locators[i].Keys);
20.     }
21.     await Addressables.DownloadDependenciesAsync(new List<object>(keys), Addressables.MergeMode.Union).Task;
22. }

 

@ProtoTerminator Thank you very much!

 

@ProtoTerminator I created two catalogs, but they have same locatorId who is AddressablesMainContentCatalog.
How do i create Multiple catalogs who hava different locatorId?

 

Hm, I'm not sure about that. @unity_bill give some guidance?
