Setting up the rooms

In the last chapter we built two rooms, Level_01 and Level_12, for testing the HUD and game difficulty. We now need to make rooms for all the levels in between those two, plus a few additional rooms for the Front End, Shop and Level Select:

  1. Create a new Room for each level from Level_02 to Level_11. Set the size of the rooms as follows:

    • Level_02 – Level_04 is set to Width: 640 and Height: 480

    • Level_05 – Level_08 is set to Width: 960 and Height: 720

    • Level_09 – Level_11 is set to Width: 1280 and Height: 960

  2. Each room needs to have Room is Physics World checked in the Physics tab.

  3. Make sure that Views | Port on Screen is set to X: 0, Y: 0, W: 640, and H: 480 so that each room will display properly on screen.

  4. We have supplied backgrounds for each level which can be found in Chapter 7/Backgrounds/. Make sure that Remove Background is not checked.

  5. Each level should have a unique tower built from a variety of Pillars and ideally be made more difficult than the previous level. Start...
