HashSet资源管理中的使用

废话不说，直接上代码：

public const string NoDepTypeFilter = "t:Model t:ShaderVariants t:Scene t:Prefab t:Shader t:Material t:AnimationClip t:Texture t:AnimatorController t:Font t:TextAsset t:ScriptableObject";

string[] filter = new string[]{".meta",".cs",".shader",".cginc"}

public void GetAssets(string[] searchDirectory)
{
    HashSet<string> hashs = new HashSet<string>();
    for(int i = 0;i < filter.Length; i++)
    {
        hashs.UnionWith(AssetDatabase.FindAssets(filter[i], searchDirectory));
    }            
    hashs.ExceptWith(AssetDatabase.FindAssets("t:Script t:LightingData", searchDirectory));
    
}

这样的话就可以获取到目录中所有想要的资源了（排除过后的）。
