After resetting, I loose the point counter and no asteroids are created. Also, could use a description on what one is supposed to do.

@ndrwdslv, thank you. You might want to check out my Bar Sub-classes scenario which demonstrates different ways to give it functionality. It is at the following URL: http://www.greenfoot.org/scenarios/5677

@RadikulRAM, the code is open source (you can download this scenario and look at the code yourself within the Greenfoot application. Just click on the big green 'Open in Greenfoot' button on the right above the scenario window frame.

What FlyingRabidUnicornPig is saying is that while editing the text in the TextBox object, if the user presses the 'Del' key, it appears to add a space.
