This is 15 lines of code simulating traffic movement in a city environment using the Dark AI expansion. So if you dont have Dark AI, this wont work.

There is no collision on the cars. They just travel about the city of thier own free will. They will travel the streets towards thier destination, turning corners at intersections.

This was a test of AI traffic using the Dark AI. Although this doesnt work all that bad, Dark AI is rather limted for car based AI.

It runs at about 30fps on my machine but if you remove the 2nd, 5th, 8th and 11th "AI Add Obstacle Vertex" lines of code, it will run at about 60fps but the cars will not turn corners as well.

Unzip the attached zip file (189k zip, 200k uncompressed... not including the source), load the project and press F5.

Have fun!

Thanks. I have another version with collision and stop lights but it wont compile down to 20 lines. But I think I'll keep expanding on it and make something of it. And yes, I will probably get Dark Physics so I'll integrate that too.

Cool, I look out for that one.

Just a thought when you make your car why not save it out as DBO then just load it in.

I'm still learning DBP. I've only had it for a couple weeks. I dont know the benefits of using a DBO... yet.

But if you can explain the benefit of saving out to a DBO that you are suggesting, that would be helpful.

Well your doing better than me on using it, I been using itfor 3, 4 years still learning to do simple things.

If you look at the noughts and crosses thread I have shown how to make and object and link it together, from there you just save it out as a DBO file for loading later.

I think the best bit is when you reloaded object, it has remeberd every thing you have done to it shape size and texture.

Plus once you have made one object you can clone it.

Also look in the DBO Challenge thread as in there we are all learning how to make objects just using the DBPro object set.

Have fun

I'd love to see this in action, any chance of having a compiled version?
