Reacting to keyboard events

In this recipe, we will make a robot stop rolling when the user presses a key. We will use a property to determine whether a robot must continue rolling. When the user presses a specific key, Alice will change the value for this property and we will notice the effect in the scene.

Getting ready

We will use an existing project that has an instance of gina as one of two characters from the Looking Glass Characters gallery.

  1. Open the project saved in the Defining a key listener recipe.
  2. Click on Edit Code, at the lower-right corner of the big scene preview. Alice will show a smaller preview of the scene and will display the Code Editor on a panel located at the right-hand side of the main window.
  3. Click on the class: MyScene
