[Any start point for AI development?]

Starcraft's probably best (BWAPI), but if you want open source, the other alternative is SpringRTS. The documentation isn't great, but it's often slightly better than "read the code", although that's oft-suggested, just like in any open source community.

[Cossacks 3 announced !]

Awesome, I'm playing a lot of EU4 right now so seeing as how this covers the same period I'm pretty excited.

Also there's the fact I used to play Cossacks 1 so nostalgia's involved.

1#Scheduled for release "this year, when it’s done" Grigorovich says, Cossacks 3 will include 12 playable nations, including France, England, Russia, Ukraine and Prussia/Austria. Each will have their own unique forces and structures. Coming to Linux, Macintosh and Windows PC, it will include 5 historical campaigns, as well as multiplayer.

I know Cossacks 1 used to have Ukraine with those awesome (best?) rifleman, but historically Ukraine didn't exist until the 20th century so it does seem weird to see it.

I assume Ottomans will be present too which should make the architecture and units have more variety.

[Mod Idea]

This was once tried for SpringRTS: http://www.imperialwinter.com/ , but has pretty much been abandoned by the authors long since.

It's available on github: https://github.com/imperialwinter/swiw.sdd so you may use that for reference. However I don't think the models are released under a free licence, and I don't think they're of the format usable for 0ad, but hey.

[How does 0ad (pyrogenesis?) synchronize simulation]

Thanks, I assume that also caused no difficulties in porting to Android.

You mind linking the source of your fixed point implementation?

[How does 0ad (pyrogenesis?) synchronize simulation]

Hello,

As the topic title, I'm interested how 0ad synchronizes simulation along multiple PCs in multiplayer.

This is important in order to ensure the same result on multiple PCs with potentialy different FPUs.

SpringRTS for example uses streflop: http://nicolas.brodu.net/en/programmation/streflop/

The assumption here is that you are using a synced engine, am I wrong?

Thanks in advance
