1) In the events pane, you can add a "when mouse is clicked on something" event. It will say "do nothing"
2) Create a new method, and add an object parameter.
3) Go back to the event, and replace "do nothing" with the name of your method and then add "What was clicked" as the parameter.
4) You now have a method that can be programmed to do whatever you want anytime an object is clicked by Using customized lists and arrays.
Happy Programming
