Data Structures For Game Programmers

Game Demonstration 16-2
===============================================================================
This the map editor for the game in Game Demonstration 16-1

There are a few major sections of the demo:
- The map: this is the big area on the upper left side of the screen. It
  represents the entire map
- The Minimap: this is the small area in the upper-left side of the screen. It
  shows a 3x3 grid zoomed in at the mouse cursor.
- The buttons: These are between the minimap and the main map. You use them
  to select a palette to draw from, or to delete a tile, item, or player.
- The palette: this is the area on the bottom left side of the screen. It shows
  at most 8 tiles. Click on a tile from this palette to select it as the current
  tile to draw
- The command area: On the bottom left there is a checkbox, a textbox, and two
  buttons. The checkbox, when checked, will make every instance of the current
  tile on the main map turn blue.
  The textbox holds the name of the file you are working on. Click Save to save
  the map to that file, or Load to load a map from that file
  
- To draw, just click your mouse on the main map after you have selected your
  desired tile, and drag the mouse where you want to draw.
- There are four layers on this map:
    - base layer
    - overlay layer
    - item layer
    - person layer
    
  The editor seamlessly combines the layers for you, so you can't draw overlay
  tiles on the base, or players on the item layer.
  When deleting tiles, the deltile button will only delete an overlay tile; the
  base tiles will always remain on the map and cannot be deleted.
  
  
There is one change from the editor in Game Demonstration 9-2 is the three new
textboxes near the bottom of the screen. In these textboxes, you will type the 
filename of the level you want that vortex to lead to, when entered.

Additionally, there is a new palette category, "Exits". Clicking on this will 
bring up the three-vortex pallette bar, which you can draw, as items.
