Who uses the A* code

I often wonder who uses the A* code. Sometimes people write to me to tell me they've used the code in their University assignments or just for fun, but has anyone used this in a project that I don't know about?

My A* algorithm on google code

During my time at Activision I worked on a code base that included some code from their game Gun, and was happy to find my code, verbatim included there too!

Also, today, I downloaded a 2d game prototyping engine called Angel, from some EA guys. When I looked at how their path finding worked, I was surprised to see my code in there too!

It's cool that people are using this code. If you do use it in some commercial or interesting project, please let me know. A credit or thank you in your product would be nice too!

I am a reader of this blog, I found here when I search some emacs related stuff. Surprisingly, you are an AI guy, so am I. although I haven't use your code, I'd like to say hello, and I will try the code if there is a chance :-)

Pleased to meet you Xw.Y

Hi Justin! I'm one of the devs behind Angel. Glad to know that you're cool with us using your A* code! :-)

Let me know if you play around with Angel anymore or if you have any thoughts/feedback about it!

Hi sjml

I've got some time on my hands and I've been stepping through the engine. Seems pretty nice so far but I've not done anything with it yet.

Hi Justin. I found your code when looking for a quick A* algorithm for a robotics motion planning problem I worked on briefly last year. You can find the results here: http://smc-it.org/abstracts-contri_papers/72.pdf

Thank you for making life easier!

hey justin,
I've been trying to develop an algorithm to make a stepper motor move over a orthogonal matrix with movements (as many as possible) in the positive OX and OY direction,I think it is possible by A star algorithm but am unable to find any way of doing it.can you help me out?

Justin, I am a hobby roguelike developer, I found your code a long time ago and use it in all my projects. Thanks a lot.
