<p dir="auto">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.</p>
<p dir="auto">Your game in file <code>game.c</code> consists of two functions:</p>
<ul dir="auto">
<li><code>void* init_game()</code> 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 <code>game</code>.</li>
<li><code>int game_event(struct event* event,void* game)</code>
is called by the game loop in periodic interval or when a key was pressed. Non-zero return value or <code>Ctrl+C</code> key interrupts the game loop.</li>
</ul>
<p dir="auto">The world variable represents state of two-dimensional grid of characters on the screen. The screen matrix looks like this:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content=" origin
[0,0] width
+--------------------+
h | |
e | |
i | |
g | |
h | |
t | |
+--------------------+"><pre class="notranslate"><code> origin
[0,0] width
+--------------------+
h | |
e | |
i | |
g | |
h | |
t | |
+--------------------+
</code></pre></div>
<p dir="auto">The world has the following parameters:</p>
<ul dir="auto">
<li><code>int height</code>: y-dimension of the grid.</li>
<li><code>int width</code>: x-dimension of the grid.</li>
<li><code>int interval</code>: maximum time between steps in milliseconds.</li>
</ul>
