For the soduko, just use for loops and do it how you would personally. Of course there is ASM: The fastest way to do it. :) The slowest way to write it. :D What's the application? There might be a way around. Let's see: log 4^25 = 25 log 4 = 50 log 2 = 15 digits = 10^15 Around a quadrillion. :shock:

Here, try this:

... 'normal code
PSET (X,Y)
PSET (U,V),0 'turns old image off
LET U=X
LET V=Y
...

That makes you pong ball move very quickly while using little memory.
MAKE SURE TO SET U AND V TO X AND Y AFTER PSET!
Good luck. That was my first program.

There's no way one tutorial can adequatly cover Physics Engines.
I'm still on vectors, and I can go on forever at this rate.

Well, There are a lot of polygons (mostly quads) too numerous for me to preplan painting, but maybe regualar enough for an algorithm. They're mostly cube sides. And by the way, the aux lines will take care of the thin triangle problem. That's my main reason for using it. A) Since Polygon edges are p...

Ok. Imagine you have a cube. One auxilary line (I made the name up) just connects one pair of diagonal vertices for each face. Then, later on paint both sides of the same color of the Aux line (but not the edges! Otherwise the computer will make a mistake and paint all over the place :) ). However, ...

Me to. I'd only make one if I got something out of it, otherwise it's a waste of time .

Tutorials are about all I can write. But I'll try. Hope my WF was good.

[8/25 edit] : I started on my Physics Engine tutorial. Should I send it to #24 or wait till #25? I think I'll be pretty long. Already 2 pages, no major source code, and I haven't even finished vectors.

I mean throwing rays at auxilery lines and painting around them, thus not "missing". Like this:
+-----+
|......./|
|...../..|
|.../....|
|./......|
+-----+
Where the "/" is the aux line and the dots are paint, and the boder is a square or something.

I meant input for the text, which would be output or append for the cource code. But I think that only works for .txt, though I'm not sure. Assmbly might be better, but I haven't the slightest idea how to use it for the keyboard.
Or you could program robotic AI to type for you.

Open text as input. I heard that you could overwrite the keyboard buffer or something like it instead, thus simulating typing.

In theory, I guess. But it will probably be more of a nucance than a threat with software and protected OSs.

Could raycasting be used to fill wireframes?

Ok...Wireframes and physics engines go hand in hand. Wireframes show 3D lines and points. Physics engines figure out what to do with the points and lines. Any interactive wireframe or just a moving one is a physics engine. Now, when most people say P.E., they mean the calc/trig based ones, such as a...

You probably did half the work. What you have to do shouldn't be that hard.

How do I get a QB program to start another QB prog?
Please, if there's a way without directories, please tell me. My dirs are a mess.

ASM, I think. It should work; if it's just interupts.

Thanks.

So it fills the entire polygon up?

I'll need an e-mail address or some other way to send (I'm not yet finished with V.2). I also don't have a physics engine program, I'm just working on the tutorial. And my engine is more of a subroutine than an entire program, unless it's a demo.

I mean color. I need a quick way to fill in already made polygons for my RPG. Many polygons.
