I'm coding a simple RTS game as a hobbie, and to learn about pathfinding algorithms, a*, strategies, flocking, etc.
I think I'm doing fine so far, but now that I have completed about 50% of the goals I wanted to achieve, I was looking for some tutorials/books to compare what I've been doing so far with the common techniques used in RTS games, but I didn't find much information.
Do you know any good books or tutorials about programming RTS games?
Best way, i suppose, would be to investigate source code of other RTS games.
There's Programming an RTS Game with Direct3D which is a bit older. The graphics part is probably somewhat outdated but the other subjects are still good (e.g. pathfinding)
I got a copy of Real-Time Strategy Game Programming Using MS DIRECTX 6.0 a long time ago and I remember thinking it was quite well done. Like the other suggestion the graphics section is obviously out of date, but the rest is solid.
The Game Programming Gems series covers a lot of the topics you mentioned. It would also be worth looking into the AI Gems series as well.
