I working on a racing game and I have a problem: To know whether the player
finished the race I test if the car position is in the finish line, but the
problem is if the player starts running, turns the car and then drives in
the wrong way it will end up winning the race L. How could I know the player
is in the wrong way? I put several check points and uncheck them if it was
already checked, but I really would like to put a sign in the screen telling
him his is in the wrong way.
Something like this might work:
// assuming 360 degrees
// edge condition checks left as an exercise for reader
if ( car_direction > track_direction + 90 || car_direction <
track_direction - 90) {
direction = WRONG_WAY;
}
if (direction == WRONG_WAY) {
lap_incrementor = -1;
can_win = FALSE;
}
