The error come in

function draw_map()
       for i=0,map_size_x-1 do
               for j=0,map_size_y-1 do
                     tex_draw(abs(map[i][j]),(i-x_map)*32,(j-y_map)*32,1)
               end
       end
end

That code looks odd...

Check that you really want
"(i-x_map)" and not "(x_map-i)".
Same with y_map.



x_map and y_map is the position of the tile at the left and the top of the screen.

If i do x_map-i, if x_map==0 then i do (-i) what is not what i want

The problem is that something corrupt lua's internal state and i don't know what...
