Can anyone help??? On what video mode are you ? Did you set the video mode and color depth using set_color_depth( [8] [15] [16] [24] [32] ) set_gfx_mode(640, 480, 0, 0); Your code should work only with 8 bits color depth. If you are using 15 16 24 or 32 bits color depth, it will not work. // using 24 bits color depth for (y = 0; y < 32*3; y++) for (x = 0; x < 32*3; x++) b->line[y][x] = 12; // 8 bits b->line[y][++x] = 12; // 8 bits b->line[y][++x] = 12; // 8 bits // total 24 bits
