Basic syntax of unity script (6) - specific folder

stay Unity During the development of the project , You can choose to create any folder that conforms to the specification name to form the directory structure of the whole project . meanwhile ,Unity Defines a series of A folder with a specific name Used to handle specified tasks , For example, the script related to the editor must be placed in Editor Folder can work normally .

Assets

  Assets Folder includes Unity All resource files used in the project . newly build Unity After the project , The folder will be created automatically . stay Project The palette ,Assets Use as root folder . also , There is no need to specify , be-all API Method by default, all resource files are located in Assets In the folder .

Editor

   Put in Editor The scripts in the folder are regarded as editor scripts , Instead of runtime scripts . The scripts in this folder are only run in the editor during development , Instead of being included build In the next project . Only scripts in this folder can access Unity Editor Of API, So as to expand the editor .

Resources

  Resources Folder allows you to access the corresponding resources through the name of the file in the script . Use Resources.Load Method for dynamic loading , Resources placed in this folder are always included build in , Even if not used . Once the project is packaged ,Resources All the resources in the folder are packed into the archive in .


   When resources are accessed as script variables , These resources are loaded into memory after the script is instantiated . If resources are too large , These large resources can be put into this folder for dynamic loading ; When these resources are no longer used , call Resources.UnloadUnusedAssets Free memory .

Resources.Load() Loading Assets The resource
resources ： The precast body 、 Model 、 texture of material 、 texture 、 Audio 、 video 、 Data document 、 Scene and so on

Be careful ：Resources This dynamic loading method is read-only , After the game is packaged , The contents of the folder cannot be modified

Resources Methods
FindObjectsOfTypeAll: Return all resources of a certain type
Load： Through the path ( Or name ) load resources
LoadAll： Load the Resources All resources under
LoadAsync： Load resources asynchronously , Through collaborative process
UnloadAsset： Unload loaded resources
UnloadUnusedAssets： Unload unused resources in memory for minutes

load resources

public class Resource : MonoBehaviour {
    
	void Start()
	{
    
		AddObjToScenes();
	}

	/// <summary>
	///  Define a load Resources Methods of resources in folders 
	/// </summary>
	public void AddObjToScenes()
	{
    
		// Load resources into the game process 
		var obj = Resources.Load("123");
		// Instantiate an asset into the scene 
		GameObject instance = Instantiate(obj) as GameObject;
		instance.transform.position = Vector3.zero;
 
        // Empty the resource from the process 
		obj = null;
		// Unload loaded resources 
		Resources.UnloadAsset();

	}
}

Plugins

  Plugins Folders are used for storing native plug-in unit , These plug-ins will be automatically included build in . stay Windows Under the platform ,native The plug-in is dll file

Plugins The folder must be Assets Direct subdirectories of folders

Gizmos

  Unity have access to Gizmos Class in Scene Draw an image in the panel to show the design details , among Gizmos.DrawIcon Function can draw an icon in the scene window to mark special objects and positions , The image file used by this function is located in Gizmos In the folder

StreamingsAssets

   When you need to use a resource that retains the original format instead of Unity Format after special processing , Its resources can be placed in StreamingAssets In the folder . The resources in this folder will be copied to the corresponding folder of the target device when the game is installed , Any platform can pass Application.streamingAssetsPath Visit

StandardAssets

  StandardAssets The script in the folder is compiled first , These scripts will be exported to Assembly-Csharp-firstpass or Assembly-UnityScript-firstpass In the project . Prevent scripts from this folder , You can use it C# Script to access js Scripts or scripts in other languages

Hide Folder

   With .‘’ start 、 With ~ ending 、 With cvs Named or with .tmp Folders with extensions are hidden folders , Resources in hidden folders will not be imported , The script will not be compiled ,Unity The existence of this folder will be completely ignored .

Script Compilation

(1) Compile in StandardAssets、Plugins All scripts in the folder . Scripts in these folders cannot directly access scripts outside these folders , You cannot directly reference a class or its variables , But you can use GameObject.SendMessage Communicate with them .
(2) Compile in StandardAssets/Editor 、 Plugins/Editor All scripts in the folder . If you want to use it UnityEditor Namespace , Scripts must be placed in these folders .
(3) Compile in Assets/Editor Outside and not in step (1) and (2) All script files in .
(4) Compile in Assets/Editor All scripts in
