This is my first release of Box2D for AutoIT. A very fun and exciting UDF to be bringing to you all. For those who don't know, Box2D is a physics engine (see http://box2d.org/). It simulates physical systems using rigid bodies and collision detection. It is arguably the most prevalent physics engine in existence, within popular physics-based games like Angry Birds using it, and is also at the core of other advanced physics engines such as Unity.
For a quick demonstration of this UDF in action see the following YouTube video -> https://youtu.be/h5QH1O63Wik
Or play "Angry Nerds", the demo game, for yourself. Visit the EXAMPLES section below.
Box2D is purely a mathematical engine. It can model physics numerically. This in itself is quite interesting, however it really shines when applied to a good graphics engine. Recently I posted my SFML UDF over here ...
After benchmarking several popular graphics engines (i.e. GDI+, Direct2D, Irrlicht and SFML) with this Box2D UDF I've selected SFML as my favourite, and the engine that I believe performs the best (fastest) with a rich set of functions appropriate for any physics engine. With Box2D married with SFML, and running on AutoIT, the results are stunning.
A HUGE THANK-YOU to jRowe and linus (for the Irrlicht UDF) and UEZ for his post on GDI+ loading screens and trancexx and Eukalyptus for their work on Direct2D. Without their talents I would not have been able to reach this point on my own.
The Box2D library is available for C++. Way back in 2010 it was ported to Pure C by "Paril" and made available on Google Code and known as "Box2C". Google Code has since been shut down but the but the archive of Box2C still exists to this day here -> https://code.google.com/archive/p/box2c. This is the library which I have ported to AutoIT in this UDF.
SFML I am also porting to AutoIT under a separate UDF, as linked above.
Building this UDF has been a dream come true. I've been fascinated by physics-based games as far back as the golden age of gaming in the 80's, with thrust style games like Asteroids and platformers like Donkey Kong. I admired game developers like Jeremy Smith who created what may have been the first true game physics engines for the home computers. I was astonished by their talents in games like Thrust and Exile for the C64. Over the years I've attempted to mimic at least some of their success in my own games but alas I can not match their skills. Now much older automation tools have become my game. I use them almost every day, AutoIT included. I've dabbled in other languages for physics game development, like Scratch and Unity, but sadly I had wondered why AutoIT, with all it's glorious capabilities and rapid scripting features, didn't have such a feature. Hence this UDF.
This UDF demands a big time investment, and I am time poor, but I have a keen interest in the topic and will do my best to continue it's development. I am only a hobbyist game developer and welcome comments and suggestions from those far smarter than I on this topic.
AutoIt3 3.2 or higher LIST OF FUNCTIONS (in progress):
I've split this UDF into two halves. "Box2C.au3" is a UDF specifically for Box2C, the C API for Box2D. It provides the mathematics behind the engine. Additionally I'm providing "Box2CEx.au3" as an Extension that provides the graphics and gaming functions for Box2D.

For such a powerful physics engine coupled to such a powerful graphics engine (SFML) it's sad that I've only had time to build one functional game, thus far. But it's a start.
My self-titled "Angry Nerds" is merely a demo of the same game concept as the ever-so-popular Angry Birds game. Angry Birds itself is built on top of Box2D. Likewise Angry Nerds. AutoIT + Box2D + SFML to be exact. I've compiled Angry Nerds and provided an installer also, so you can quickly run the demo for yourself. From the Github site below (in the DOWNLOAD section) run "Box2C_Angry_Nerds_Game_SFML_installer.exe" to install the demo to a location on your computer (desktop by default). Go into this folder and run "Box2C_Angry_Nerds_Game_SFML.exe". All instructions are displayed in-game. Should be quite easy to work out.
Aside from Angry Nerds there are also two test scripts:
Box2C_linear_forces_test_SFML.au3 Box2C_angular_forces_test_SFML.au3 Feel free to run these for a basic demonstration of rigid bodies, forces and collisions. The heart of Box2D and any physics engine.
Lastly I also have four speed tests as follows:
Box2C_speed_test_SFML.au3 Box2C_speed_test_Irrlicht.au3 Box2C_speed_test_D2D.au3 Box2C_speed_test_GDIPlus.au3 These were my initial evaluations into a suitable graphics engine for Box2D. I've since settled on SFML, but feel free to execute these. Note they may become quick defective over time as the SFML functions slowly take over.

Hope you all enjoy! I certainly am :-)
First off, yeah this may be the lamest title. But it made you look anyway!
Edit: Now updated! With step-counter, reset button and a few GUI-tweaks. (the step-counter is cheating! It's calculated in advance...)
I recently thought a screenshot of a finished maze may be smart to show, instead of only my long story and code. o=path, x=wall. Here it is:
I started making my own implementation of the A* pathing script in a larger project, inspired by Toady's work. (But made one from scratch myself anyway )
After the A* pathing script was working (not cleaned up yet) I wanted to test it. Unfortunately I got no good, randomized, maze lying around that also had the format I needed. So I made my own maze generator!
I did a few hours of research on the matter and then a few evenings of scripting.
For the people who are interested, one of my problems was that I needed 'one-cell' thick walls. Most maze generation have 1 pixel thick walls drawn by a line, that could be opened if a path is needed. The solution is so simple, I needed this guy to tell me. Click here for my inspiration source.
This generator can be used with different sizes maze, even uneven ones! Just set the width and height settings. FYI, it must be odd numbers for this maze to work with it's containment walls.
It's the 'simple' Depth-First Search, with backtracking. And without further ado; my a-maze-ing generator!:

P.S. The 'slow' generation is intended because it looks cool. Comment out the Sleep line on line 157 for a fast generation.
Hey guys! I need to find a way to wrap an autoit gui around a game. I am planning on making a custom gui overlay for interacting with my stream, which will allow me to run giveaways and stuff like that. But I need to find a way to force the steam games to run inside my autoit gui... I have the following code so far credit to those I took code from and modified to suite my needs "can't remember who u are pls post if i owe ty to u" If I select notepad and launch it then it works great! and the notepad window is wrapped inside my gui. However if I try it with teamfortress 2 it won't work...

AUTOITEROIDS is a remake of the video arcade game released in 1979 by Atari, Inc.
It was one of the most popular and influential games of the Golden Age of Arcade Games.
The player controls a spaceship in an asteroid field which is periodically traversed by flying saucers.
The object of the game is to shoot and destroy asteroids and saucers while not colliding with either,
or being hit by the saucers' counter-fire.
ctrl - shoot,
up - thrust,
left - turn left,
right - turn right,
space - hyper jump
game is starting with 3 asteroids
every 10.000 points increase of level (among other things amount of asteroids + 1)
every 30.000 points extra live
biggest asteroid = 20 points
medium asteroid = 50 points
smallest asteroid = 100 points
big alien spaceship = 200 points
small alien spaceship = 1000 point

Is there a way to make within AutoIt a 3D game or at least 3D Images?
I think it'll look at the end with an Array Holding masses of Pictures which are being placed at the end.
If this won't be possible anywayis there a 2D UDF?
