AssetDatabase.SaveAssets

説明

保存されていないアセットの変更点をすべてディスクに書き出します。

Identical to EditorApplication.SaveAssets except not permitted to be called during serialization.

When calling this function, AssetModificationProcessor.OnWillSaveAssets will be invoked, allowing you to override which files are saved to disk.

EditorApplication.SaveAssets will be deprecated in a future release. Please use SaveAssets to maintain future compatibility.
