@Collin, the scenario does not pause, but stops, when the spacebar is pressed. Basically with: if (Greenfoot.isKeyDown("space")) Greenfoot.stop();

Once the scenario is stopped, no keystroke action will start the scenario back up. Programmatically preventing the actions of your actors is the only way to make the scenario appear to be paused and still have a key detected to lift to prevention.

@Collin, let me clarify. Off-line, using the greenfoot application, you can use 'Ctrl-R' to run or restart the scenario; but, this will not work here on the site.
