Hey Brent,

Oh, just for fun, a few remarks:

> class block{
>             public:
...
>                    int give_block(){return colour;return hp;return
x;return

What's that supposed to do?

>                    void draw_block(int a,int b,int c,int d){colour = a;hp
=
> b;x = c;y = d;rectfill(screen,x,y,x + 20,y + 5,colour);}

Or, use the coordinates stored in your object. Call block->draw (screen);
Or screen->draw (block);

    level[0][0].setCoordinate (10, 10);

This is a no-op..

> 1].y,level[i][j + 1].x + 20,level[i][j + 1].y + 5,0);

This is hard to read, use level[i][j].draw(), and perhaps
level[i][j].clear() to restore the background. For a better way of dealing
with game loops, see the Allegro game programming tutorial.

No, you didn't include the main control loop and a lot of other stuff. Try
using gdb to see what goes wrong.

Have fun :)
