Unity 导入项目tag与layer的方法
UnityEditor》AssetPostprocessor 控制导入的脚本
类中的方法字段
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 文件的数据
以下时TagManger的数据
这些内容手动配置是无法更改引擎内的数据的
//Mono挂在网上的脚本新版本存在两个问题
>layer 层 在index8之后才能设置
>tag 默认size为 0
可能时mono 16年的帖子针对5x版本可行但是针对17版本不可执行

{
string[] tags = TagsAdd.Split('&');
string[] Layers = TagsLayer.Split('&');
foreach (var tag in tags) AddTag(tag);
foreach (var layer in Layers) AddLayer(layer);
//Debug.Log("loading....");
return;
}
}
}
static void AddTag(string tag)
