For now there is progress only with uniforms, guys who helped me earlier stopped for a time their work (on buildings and scenes), so for now I'm working alone and I have time only for uniforms.
I'll need many scripts, most important and most difficult of them probably is AI-controlled artillery with crew of 2 or 3 men (they can be replaced with nearby units with decreasing accuracy comparing to artillery units), in Warband there are siege towers which move only when there are soldiers near them, artillery can be made in similar way I guess, but I'm only beginner in Python, so such script I can't write myself.
And there will be plenty of other scripts, as example mine warfare - there will be tunnels (mines) underground in different directions, filled with destructible earth, so sappers can dig these tunnels, and there will be places, where explosion can be made, which will destroy part of defences, or make a big crater on the surface, and defenders can dig counter-mines and with directed blast destroy part of attacker's mines. But maybe it's too difficult, I don't know.
Also I'll need scripts for 6-horses artillery train, so on each left horse there will be player (or maybe bot), if horse is killed - it's corpse must be unharness, if rider is killed - there will be pauses in control of horses. With each killed horse decreases speed of train (if there are all six of them, they can gallop as ordinary heavy horses). It can be used in multiplayer, so we'll have fast horse artillery
But most important script is scripts for AI-controlled guns.
