1. Lecture: 17-1

• Prerequisites for this lecture are: 16-1, 16-2 and 16-3.

2. Implementation of Touchmap 0.2

• last week we adpated touchmap-0.1 to use an indirect function call to implement a spawn button
  • this worked and could be extended to implement many other buttons
• however it is an ugly implementation
  • although it was very minimal (in terms of code line changes)
• it would be cleaner to adopt an object oriented approach
  • albeit the number of lines of code will increase
• one of the major issues of a touchmap implementation is the ability to change a tile in the grid
  • currently it changes:
    • a blank to a wall
    • a wall to a door
    • a door to a blank
• we need a spawn, hellknight, ammo, ticks etc
  • the indirect function call can do this but it will result in messy code

3. Touchmap 0.2

• removes the indirect function call
  • but introduces a new class button
  • and about 20 lines of extra code
• touchmap-0.2 can be downloaded using:

• $ cd
  $ cd Sandpit
  $ wget http://floppsie.comp.glam.ac.uk/download/targz/touchmap-0.2.tar.gz
  $ tar zxf touchmap-0.2.tar.gz
  $ ls touchmap-0.2

• and can be built using:
• 
  $ cd
  $ cd Sandpit
  $ rm -rf build-touchmap
  $ mkdir build-touchmap
  $ cd build-touchmap
  $ ../touchmap-0.2/configure
  $ make
• and you can run it via:
• 
  $ cd
  $ cd Sandpit/build-touchmap
  $ ./localrun.sh touchmap.py
