World Game Library

+

Learn asycnronous C programming by a game.

+

The library implements a game loop for a character-based ncurses game;

+

The library finds out the event types:

+
    +
  • start and end
    • +
  • mouse events
    • +
  • keyboard events
    • +
  • screen resize events
    • +
+

It can print colors and arbitrary characters on the screen. +Running is interrupted when character is drawn out of the screen.

+

Installation and Running

+

Make sure, that ncurses is installed.

+

Clone this repository.

+

Compile:

+
make
+

Run:

+
./game
+

Make your own game

+

The game happens in a rectangular world of colorful characters. +Your goal as a programmer is to modify the world according to the pressed keys and the internal game state. +The library implements the game loop and draws the world to screen.

+

Your game in file game.c consists of two functions:

+
    +
  • void* init_game() is called in the beginning. Here you can initialize the internal state of the game. +The function should return a pointer to an instance of the initial game state game.
    • +
  • int game_event(struct event* event,void* game) +is called by the game loop in periodic interval or when a key was pressed. Non-zero return value or Ctrl+C key interrupts the game loop.
    • +
+

The world variable represents state of two-dimensional grid of characters on the screen. The screen matrix looks like this:

+
   origin
+   [0,0]     width
+  +--------------------+
+h |                    |
+e |                    |
+i |                    |
+g |                    |
+h |                    |
+t |                    |
+  +--------------------+
+
+

The world has the following parameters:

+
    +
  • int height: y-dimension of the grid.
    • +
  • int width: x-dimension of the grid.
    • +
  • int interval: maximum time between steps in milliseconds.
    • +
+

The Event Function

+

The int game_event(struct event* event,void* game) +function should:

+
    +
  1. Read the game state (from the void* game) pointer.
    2. +
  2. Examine the pressed key from event pointer. If the key variable is non-zero, a key was pressed. According to the pressed key, modify the game state game.
    3. +
  3. Draw the game state. In the beginning of the step function the screen is empty.
    4. +
  4. Returning non-zero value ends the game loop.
    5. +
