Component-level overview

• Graphics. The following systems have been identified:
  • Tile subsystem. Displays terrain, etc. Will probably need to do some minimal compositing and z-ordering to draw things on top of other things.
  • Sprite subsystem. Displays offense player's ship, and defense player's turrets, defenses, etc. Bullets / weapon fire. Possibly special effects.
  • Menu subsystem. Displays health and status information. APIs to create buttons or windows to handle defense player's level editing. etc.
• Gamplay. The following systems have been identified:
  • Game entities, including offense player's ship, defense player's defenses, bullets / weapon fire, things to do / simulations with the power system, terrain, etc.
  • Basic 2D physics and collision detection.
• Network. Need to propagate updates in the game state to the other player's system. Assume a fast network.
• Sound
