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 will be set to title and the info will be set to info. Progress should be set to a value between 0.0 and 1.0, where 0 means nothing done and 1.0 means 100% completed.

This is useful when you perform a long blocking operation in an Editor script, and want to notify the user about the 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.

This function's return value indicates whether the user pressed the cancel button. You must stop the task that is in progress. After you display the progress bar, clear it using ClearProgressBar.
