Unity 導入項目tag與layer的方法

 

UnityEditor》AssetPostprocessor 控制導入的腳本

 

類中的方法字段

public string assetPath { get; set; }

public AssetImporter assetImporter { get; }

public Texture2D preview { get; set; }

 

public virtual int GetPostprocessOrder();

public virtual uint GetVersion();

public void LogError(string warning);

public void LogError(string warning, [DefaultValue("null")] UnityEngine.Object context);

public void LogWarning(string warning);

public void LogWarning(string warning, [DefaultValue("null")] UnityEngine.Object context);

 

能夠注意下projectsetting 下的assets 文件的數據

如下時TagManger的數據

 

這些內容手動配置是沒法更改引擎內的數據的

 

//Mono掛在網上的腳本新版本存在兩個問題

>layer 層 在index8以後才能設置

>tag 默認size爲 0

可能時mono 16年的帖子針對5x版本可行可是針對17版本不可執行
