EditorUtility.DisplayCancelableProgressBar

説明

キャンセルボタンのあるプログレスバーを表示します

The window title sets to title and the info sets to info. Set progress should to a value between 0.0 and 1.0, where 0 indicates nothing is loaded and 1.0 indicates loading is complete.

This is useful when you perform a long blocking operation in an Editor script, and want to notify the user of progress. Use this method for long operations that make the Editor non-responsive. For long operations that happen in the background, use the Progress class instead.

A return value of true indicates that the user pressed the Cancel button. When the return value is true, you must stop the task that is in progress. After you display the progress bar, use EditorUtility.ClearProgressBar to clear it.
