Function Documentation

is_close_to_enemy()

int is_close_to_enemy	(	int	x,
		int	y )

Check if a cell is close to an enemy (based on ENEMY_MIN_DISTANCE)

Parameters

x	the x coordinate of the cell
y	the y coordinate of the cell

Returns

1 if the cell is close to an enemy, 0 otherwise

Definition at line 57 of file map_populator.c.

                                    {
    for (int i = -ENEMY_MIN_DISTANCE; i <= ENEMY_MIN_DISTANCE + 1; i++) {
        for (int j = -ENEMY_MIN_DISTANCE; j <= ENEMY_MIN_DISTANCE + 1; j++) {
            if (map[x + i][y + j] == GOBLIN || map[x + i][y + j] == START_DOOR) {
                return 1;
            }
        }
    }
    return 0;
}

is_dead_end()

int is_dead_end	(	int	x,
		int	y )

Check if a cell is a dead end (is floor and has only one neighboring non-wall cell)

Parameters

x	the x coordinate of the cell
y	the y coordinate of the cell

Returns

1 if the cell is a dead end, 0 otherwise

Definition at line 17 of file map_populator.c.
