How to implement a restart screen like in Pokey Ball?
That is, when you lose, the screen dims slightly, and the inscription tap to restart is displayed, and when you click anywhere on the screen, the level restarts. It needs to be all on the same stage.
I tried to do it through SceneManager.LoadScene(SceneManager.GetActiveScene().name); Accordingly, when I lose, the panel is displayed, but I don’t restart the level, but restart the scene and at the same time go to another level, and the panel is not hidden back.
