Re: [tuxracer-devel] Speed Boosts

[Bill S. <Bil...@Ve...>]

Course sent as requested.  Looking forward to your review ;-).

The speed stuff was trivial, but I'll put some of the relevant code here:
In render_util.c I added the following two functions:

    void print_speed()
{
    char buff[30];
    float v;

    flat_mode();

    v = (g_game.current_speed / 0.44704);

    sprintf( buff, "%.1f MPH", v );

    if (v > g_game.max_speed) {
      g_game.max_speed = v;
    }

    print_max_speed();

    glColor3f( text_colour.r, text_colour.g, text_colour.b );
    glRasterPos2i( 85, 5 );
    print_string( GLUT_BITMAP_HELVETICA_10, buff );

void print_max_speed()
{
    char buff[30];

    flat_mode();

    sprintf( buff, "%.1f MPH Max", g_game.max_speed );


    glColor3f( text_colour.r, text_colour.g, text_colour.b );
    glRasterPos2i( 150, 5 );
    print_string( GLUT_BITMAP_HELVETICA_10, buff );
}


g_game.max_speed get initialized where the other stuff does at the start of a
game.
print_speed() is called right after print_time() in racing.c
print_max_speed() gets called in game_over so you can see your max speed at the
end.
The 0.44704 in print_speed converts meters/second to miles/hour.


I'm no C coder, so don't laugh if any of it is pathetic.  I basically just copied
the pattern
of print_time.

Enjoy!
