EditorSceneManager.SaveScene

Parameters

Returns

bool True if the save succeeded, otherwise false.

Description

Save a Scene.

All paths are relative to the project folder, such as: "Assets/MyScenes/MyScene.unity". Folders specified in the path must already exist before calling the function. If no path is specified, the path of the current open Scene is used, except if it was never saved before, in which case a save dialog is shown.

The function returns false if the save failed. This can happen if the specified path is invalid or if the user cancels in the case of a save dialog.

Example: [SimpleAutoSave.png]
Simple Editor Window that saves each 300 seconds the current Scene.

Note: This saves the Scene whether it is marked dirty or not.
