EditorUtility.DisplayProgressBar

描述

显示或更新进度条。

窗口标题将设置为 /title/，信息将设置为 /info/。 进度应设置为 0.0 和 1.0 之间的一个值，0 表示一点儿也没有完成，1.0 表示完成 100%。

This is useful if you perform a long blocking operation in an Editor script, and want to notify the user about the progress. Note that this method is intended to be used for "modal" operations, i.e. a long operation that would make the editor non-responsive. For long operations that happen in the background, use Progress class instead.

After showing the progress bar, call ClearProgressBar to clear it.
