• game loading
  • libraries loading
  • game's elements, values and textures loading

    • rendering
      • 2 different zones: warzone and GUI. GUI is above warzone
      • non unique elements such as targets, towers and projectiles dynamically rendered with a template
    • moving
      • elements move at each frame, depending on movement-related data they hold
      • use of maths to calculate velocity on X and Y axis
    • shooting
      • target detection with a system of tower range
      • target movement prediction for towers to shoot where they will be when the projectile arrives, not where they are when the projectile is shot
    • hitboxes handling
      • any object that goes out of the screen is destroyed
      • projectiles hit targets and reduce their HP or kill them if their HP is under 1
      • towers cannot be placed on the path, other towers or the GUI
    • time
      • time control currently set at 60fps
      • time displaying on stderr messages
    • game over
      • targets deal damage to the base when reaching the end of the path
      • when base's hp are below 1, the game is finished and returns to the main menu
• game closing
  • unique static closing for static elements
  • dynamic closing for dynamic elements
• game informations
  • use of fprintf and stderr in order to print informations about various elements of the game, customizable via defines.h

File organisation

Unique files are stored in the directory c. Example: ./c/main.c

Category-specific files are stored in a directory which name corresponds to a category. Example: ./c/render/render.c.

Generic files are stored in a directory which name is written in uppercase with a leading underscore. Their name starts with the category name in uppercase. Example: ./c/_LOAD/LOAD_rect.c
