What does your OS look like? (Screen Shots..)

U365 console. Still WIP with bugs.

Looks rather nice. You should add a cursor, though.

I know.

It's not much yet.
Next I need to write a memory allocator.

For your 12GB of ram

Yeah I was just testing. Normally it only runs with 1G.
I just count the size of all of the usable memory areas that grub gives to me and then print it out.

Doesn't look like much, but I implemented a line-drawing algorithm:

What are the odds, I just got mine yesterday too!
but for some reason, mine only does diagonal lines...

You'll need a separate routine that draws horizontal line from a specified X/Y and width, and another that draws a vertical line from a specified X/Y and height. Then before actually drawing in your draw_line routine, you can arrange your values so that x2 > x1, and y2 > y1, then do something like this:

Code: Select all

if(x2 == x1)
{
	draw_horizontal_line(x1, y1, x2-x1, color);	// draw_horizontal_line(x,y,width,color)
} else if(y2 == y1)
{
	draw_vertical_line(x1, y1, y2-y1, color);	// draw_vertical_line(x,y,height,color)
} else
{
	// your real line-drawing code goes here...

Okay, thanks; but I meant: If the line isn't horizontal or vertical, it is perfectly diagonal. It refuses to draw lines at a slope like yours

I used the naive line-drawing algorithm from this Wikipedia page.

Maybe you're using integer division.

[BrightLight]

Maybe you're using integer division.

Actually, it works perfectly fine with integer division. I'm not using any floating point numbers in this routine.

[Techel]

If cheapskate's using an other algorithm, he could have made the mistake of using integer divisions instead of floating/fixed point ones as required in the algorithm.

I used Bresenham's, so It should've been alright, but idk...
