Hi, I would like to create some games which are simple in rules and graphics, but include some AI on which I can practice my skills. Any suggestions for those? I would also like to create a small sandbox to test AI's in, but I wouldn't know how to start such a thing of. Any ideas are welcome. Thank you

Thnx for the quick reply, but I'm not quite acustomed with c++. I know vb.net and c# and I understand c++ code, but I can't write it yet.

Any ideas how to write such a thing on my own.

Actually, I am interested in finding an AI sandbox where I can experiment too, but I would be happy to write everything in C++. It might be considered a mini-hijacking of this thread, but if people have good suggestions that require C++, please post them.

Open Steer seems to be a good approach, but it's very limited in scope, and I am not particularly interested in steering behaviors. I am looking for something more symbolic, where there are object and characters and the agent has a range of actions available to interact with the environment (think "The Sims").

If such a thing doesn't exist, I might create one as a project this Summer.

Unless of course you focus on developing games under the XNA framework, in which case you're unavoidably bound to .NET and C#! ;)

A while ago I made a little program in Python that displays a field of cubes and pyramids, and allows an external program to communicate with it by the stupidly simple method of reading and writing text files to the same directory as the program. A few people have played with it by hooking it up to chatterbot-type AIs, giving them some kind of context to talk about.

Since I built a simple scrolling tile engine with sprites and a basic notion of physics (gravity, basic collision, and motion) and sensation (objects have some sensory data that can be pinged only by nearby viewers), there was some version that I'd jury-rigged to be controllable in the same way as the above program. Is that something that anyone would be interested in seeing? It's ugly but would let anyone's AI program do some basic actions in a standard mini-world.

What I want is a sandbox where the interface is accessible easily from any language you want to program your AI in; and where the AI controls a body that has specific, limited senses in relation to a set of physical objects in a simulated world. We could then test AIs with some standard tasks like "bring three related objects to Point A and explain in English what their relationship is," and have the AI be doing more than making abstract reasoning in a vacuum. Because there's a lot of research going on already about navigation, I don't much care about that topic and would avoid making it hard for a character to get around the world.
