Make a button that can be enabled and disabled

To create a button:

• click on the paint new sprite icon.
• draw a black rectangle
• than draw another rectangle in grey and place it slightly above so that the black rectangle looks like a shadow

• use the text tool to put text on the button

• click OK to save the new sprite and rename the sprite Button

• now copy the costume and change the font color of the text on the button to a lighter color so   that it looks as if the button is disabled

• The script for the button sprite could be something like this:

• Remember that the button sprite cannot change the properties of the stage or any another sprite.  The only way to make such changes is to broadcast a message to the other sprites/stage to make these changes to themselves.  (attributes of an object is private and encapsulated)
