C语言迷宫中的启发式函数

Question

int heuristic(Maze* maze, int x0, int y0, int x1, int y1)
{    
    return abs(x0 - x1) + abs(y0 - y1);    
}

I am searching heuristic function for a maze which includes the altitudes. I found a code with two parameters(x and y). Is there a possibility to have heuristic function which includes axe z(for altitudes) ?

Answer 1

int heuristic(Maze* maze, int x0, int y0, int x1, int y1, int z0, int z1)
{
    return abs(x0 - x1) + abs(y0 - y1)+ abs(z0-z1);
}
