====Current Progress====

__Goals for week of 1/8:__

  * Primary goals
    * Add a Collision class which contains all the relevant information about a Collision, so that Pieces don't have to contain pointers to other Pieces when they collide; instead I can have a single list of Collisions and process them separately from the Pieces.
    * Rewrite the collision-detecting and collision-processing code to make use of this.
    * <del>Rewrite the piece-interaction code.</del>
    * <del>Add Walls and collisions between Pieces and Walls.</del>
    * <del>Add Attractors and Repellors, which pull/push objects away by "gravity" when certain conditions are met.</del>
      * <del>Come up with a way to implement Attractors and Repellors, as I now realize that my initial idea doesn't really make sense.</del>
  * Secondary goals
    * <del>Add piece-specific Obstacles.</del>
    * <del>Turn-based play.</del>
      * <del>Players take turns.</del>
      * <del>Only one piece can be shot off at a time (wait until all pieces are inactive).</del>
    * <del>Come up with a format for describing levels.</del>
      * <del>Add a level-loader.</del>
    * Menus.

__Goals for week of 4/7:__

  * Primary goals
    * <del>Clean up my code.</del>
      * <del>Take code out of .h's and move into .cpp's. Just one issue remains; for some reason the linker fails if I move the ''integrate'' function code into ''Physics.cpp''.</del>
        * <del>Modify makefile to reflect this.</del>
      * <del>Make better use of references and pointers.</del>
      * <del>Use data structures more intelligently.</del>
    * <del>Add an OS check so code will compile and run on any platform.</del>  (Well, Linux and Windows, at least.  Mac testing will come later.)
    * <del>Fix collision response.</del> Now using impulses on collision, and it's MUCH better.  But I'm just doing an Euler integration on the impulses; I should fix this at some point but it's not a high priority right now.
    * Add a secondary collision detection routine where triangle pieces are involved.  Harder than I thought to use a pixel-based collision detection in SDL; does SDL_image even give you direct pixel access in any way?  I can't find out how to do that. [edit: Thanks, Joseph!]
    * <del>Fill out and send in my forms to Google!!!</del>
    * <del>Send in a picture of myself for the winlibre SOC gallery.</del>
  * Secondary goals
    * <del>Add a sound routine to play sound effects on collisions, etc.</del>
    * <del>Start moving the demo more in the direction of the game.</del>
    * Try to speed up game loop computations (primarily collision detection and integration)
