Key.isDown

Summary

Listening..... waiting.... watching.... a whole world of possibilities suddenly opens up when you work with key listener functions. We learned these two in this lesson:

Key.isDown(Key.UP)
Key.isDown(Key.DOWN)

You'll want to use Key.LEFT and Key.RIGHT to move the ship on the X axis. And guess what, there are quite a few more where that came from! Here's an alphapbetical list:

Key.BACKSPACE
Key.CAPSLOCK
Key.CONTROL
Key.DELETEKEY
Key.DOWN
Key.END
Key.ENTER
Key.ESCAPE
Key.HOME
Key.INSERT
Key.LEFT
Key.PGDN
Key.PGUP
Key.RIGHT
Key.SHIFT
Key.SPACE
Key.TAB
Key.UP

In the next lesson, we'll use math to make our vertical movement a little more natural.
