Renaming the method

To rename the method, do the following:

• Select world in the object tree.
• Select the methods tab in the details pane.
• Right-click on the method named my_first_method, select Rename in the popup menu that appears, and enter main as the new name.
• Examine the line of text in the Events pane in the upper right portion of the screen and confirm that it now reads "When the world starts, do world.main();"  (This will cause your main method to execute first each time you play your world.)
