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);
可以注意下projectsetting 下的assets 文件的數據
以下時TagManger的數據
這些內容手動配置是無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之后才能設置
>tag 默認size為 0
可能時mono 16年的帖子針對5x版本可行但是針對17版本不可執行
