Unity 编辑器功能之查找预制体-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity 编辑器功能之查找预制体。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

static readonly string[] PREFAB_PATHS = new string[]
{
"Assets/GameRes/UIPanel",
};

//预制体存放路径

思路通过文件夹得到所有的预制体，生成预制体，然后遍历所有预制体以及子物体是否存在主键T如果存在进行callback操作，操作完之后根据savePrefab 进行保存，然后销毁

static void ScanPrefabComponment<T>(Action<string, T> callback, bool savePrefab = false)
{
for (int i = 0; i < PREFAB_PATHS.Length; ++i)
{
DirectoryInfo dir = new DirectoryInfo(PREFAB_PATHS[i]);
FileInfo[] files = dir.GetFiles("*.prefab", SearchOption.AllDirectories);

for (int j = 0; j < files.Length; ++j)
{
string prefabPath = files[j].FullName.Substring(files[j].FullName.IndexOf("Assets"));
try
{
GameObject target = AssetDatabase.LoadAssetAtPath(prefabPath, typeof(GameObject)) as GameObject;
target = PrefabUtility.InstantiatePrefab(target) as GameObject;
_ScanPrefabComponment<T>(prefabPath, target.transform, callback);
if (savePrefab)
{
PrefabUtility.SaveAsPrefabAsset(target, prefabPath);
}
GameObject.DestroyImmediate(target);
}
catch (Exception e)
{
Debug.LogError($"Analyze prefab: {prefabPath} failed: " + e.Message + " StackTrace: " + e.StackTrace);
}
}
}
}

static void _ScanPrefabComponment<T>(string prefabPath, Transform transform, Action<string, T> callback)
{
T comp = transform.GetComponent<T>();
if (comp != null)
{
callback(prefabPath, comp);
}

for (int i = 0; i < transform.childCount; ++i)
{
_ScanPrefabComponment(prefabPath, transform.GetChild(i), callback);
}
}

//编辑器按钮

[MenuItem("Tools/AddCanvas")]

public static void AddButtonScaleEffect()
{
parent = GameObject.Find("Canvas").gameObject;
ScanPrefabComponment<UIPanel>((prefabPath, text) =>
{
if (text.gameObject.GetComponent<GraphicRaycaster>() == null)
{
GraphicRaycaster graphicRaycaster = text.gameObject.AddComponent<GraphicRaycaster>();
isChange = true;
}
if (text.gameObject.GetComponent<Canvas>() == null)
{
Canvas canvas = text.gameObject.AddComponent<Canvas>();
canvas.overrideSorting = true;
canvas.additionalShaderChannels = AdditionalCanvasShaderChannels.TexCoord1 | AdditionalCanvasShaderChannels.TexCoord2 | AdditionalCanvasShaderChannels.TexCoord3;
isChange = true;
}
if (text.gameObject.GetComponent<CanvasScaler>() == null)
{
CanvasScaler canvasScaler = text.gameObject.AddComponent<CanvasScaler>();
isChange = true;
}
});
}
