ResourceCache helps you store data in your device's memory and interact with it. Methods for downloading cached resources (other than GetAssetBundle) use methods provided by the ResourceCache static class. Used to get the path to the encrypted file, if any. It is used to extract the hash from the manifest Provides the address of the video file to play as a stream.Дetermines the current version AssetBundle. Provides downloading of an audio recording with the ability to save it to the cache. Implements downloading images with the ability to save them to the cache. It is intended for downloading files in text format.ДЄllows you to get data from the network in the form of a `byte ' masiiv. It is used to find out the size of a file in external storage. It is used for interaction with the network: sending requests and receiving data. To interact with the remote server, I decided to create a static class Network in which I defined the main methods for loading various types of resources. It only indicates that this method can contain one or more await expressions. It is also worth noting that the word async, which is specified in the method definition, does not automatically make the method asynchronous. However, the asynchronous method cannot define parameters with the out and ref modifiers. The return type is one of the following: void, Task, Task, ValueTaskДЄn asynchronous method, like a normal one, can use any number of parameters or not use them at all.The method contains one or more awaitexpressions.The method header uses the async modifier.Asynchronous methods in C#ДЄn asynchronous method has the following features: In them, I took out the loading of resources from the main stream. To solve these problems, _ asynchronous methods_will come to the rescue. This complicates the handling of errors, which are not uncommon when working with the network. The second significant disadvantage of Coroutine is that the try- catch- finallyconstruction does not work in them.

I noticed this when I decided to animate the visualization of the image download progress. Accordingly, such resource loading loads the main thread, and the more the thread is loaded, the slower the downloads become. This allows other processes to run in parallel with loading, but it's no secret that Coroutine is executed in the main thread. Get downloaded asset bundle AssetBundle bundle = DownloadHandlerAssetBundle. Using ( UnityWebRequest uwr = UnityWebRequestAssetBundle.

In the standard documentation, you are offered to take out the loading process in Coroutine:

Its author Ichimitsu told me how to make this process as fast as possible, for which I am very grateful to him! What's wrong with Coroutine The article Working with external resources in Unitењ“D helped me a lot to organize the loading of resources from external sources. Therefore, to load media resources, it turned out to be optimal to use specialized methods provided by the UnityWebRequest class. The developers provided the ability to download all the resources via AssetBundle, but this turned out to be inefficient because it took a considerable time to unpack even small images. To do this, use AssetBundles, they can be used to load many different entities into Unitењ“d, including entire scenes. So I started looking for the possibility of loading scenes, and as it turned out, there was such a possibility. But why make a new data structure when all this is in the scenes in the most visual form. This could be done by using procedural generation, loading a json file with the coordinates of the transitions and the identifier of the new location. In addition to images, sounds, and videos, I needed to load and position interactive elements to make transitions between locations. In Unitењ“d there is a class UnityWebRequest that helps to load various types of resources from the Internet. The main concept was the ability to add new locations with panoramic views without updating the entire app. While working on the VR project Panoramic View, I set myself the task of making downloading content for this application as flexible and convenient as possible. A module for unitењ“d that allows you to upload resources from the Internet to the application.
