A little of what you have already learned

Earlier, I taught you about methods.

I taught you how to interactively call methods to manipulate the players in a world.

I explained that interactively calling methods provides the following benefits:

• The ability to manually set the stage in a more precise manner than just dragging objects around with the mouse.
   
• The ability to create short animation sequences and manually execute them one step at a time to test them.

I explained that future lessons would use program code to do most of the work required to set the stage.
