Unity3D resource loading Resources

1. Blog introduction

This blog introduces the resource loading class Resources

2. Content

FindObjectsOfTypeAll	Returns a list of objects of this type
Load	Load a path of resources from the Resources folder
LoadAll	Load all resources under a path from the Resources folder
LoadAsync	Asynchronously load resources in the path from the Resources folder
UnloadAsset	Unload resources from memory
UnloadUnusedAssets	Uninstall unused resources

FindObjectsOfTypeAll : The objects to be searched include the objects in the scene directory and the objects in the resource list. In the following demonstration, I output all objects with the Test.cs script. I mount the Test under the Main Camera and make the Main Camera into a prefab. Body, cut off the connection of the prefab in the scene, and modify the name, and both objects are output.

Load : load is very simple, you can load it by specifying a path under the Resources directory, and you can also specify the type of loaded resource when loading. The writing method is different.

	        var cube = Resources.Load("Prefab/Cube");

		GameObject cube = Resources.Load<GameObject>("Prefab/Cube");
		
		GameObject cube = Resources.Load("Prefab/Cube") as GameObject;
		
		Instantiate(cube);

LoadAll : Load all objects in the specified directory, you can specify the type to load

	        //加载Prefab目录下的所有对象
		var prefabs = Resources.LoadAll("Prefab");
		
		//加载Prefab目录下的所有GameObject对象
		GameObject[] prefabs1 = Resources.LoadAll<GameObject>("Prefab");

LoadAsync : Load resources asynchronously, load resources through coroutines, and return a ResourcesRequest, and the loaded resources are in the asset.

	
	StartCoroutine(LoadPrefab());

	IEnumerator LoadPrefab()
	{
		ResourceRequest request = Resources.LoadAsync("Prefab/Cube");

		yield return request;
		
		Instantiate(request.asset);
	}

UnloadAsset : directly unload the resources loaded in the memory.

Tested it, it's useless. . . . . . . . . . .

UnloadUnusedAssets : Unload all unused resources in memory

The test is very easy to use

Resources.UnloadUnusedAssets();
