A little thing I'd like to see in sieges...

Yeah, probably Athens too..but then again, such hills should't be modded to unrealistic scales.

well before everyone yells at me for how stupid this idea is, you have to understand I dont know anything about modding so I dont know whats possible but here it goes.
Troops can be placed on walls and on ground, while artilley can only be placed on ground right? Is it possible to alter the code of the tower/wall/plateau that uses the ground data on the wall? example: use the road data on the wall since the wall walkway is hard coded? possible or am I just stupid?

[Simetrical]

Basically, not so anyone's figured it out. Something vaguely along those lines may be possible, but any such solution would probably require giving up stuff like the towers (which can't be stuck randomly around the place—they have to be part of a contiguous wall, which can't have siege engines on it).

well, probably the bgi problem will be when you cracked that code shit will really begin: people dragging ballista's/onagers up the stairs? major issues will be on the way when the manuever. still nice idea. not stupid at all

[soibean]

hah thanks for the support. If that is possible couldnt you just have a spot on the towers that you could place the onagers during battle deployment? That way you have one shot at doing it, and if not then thats too bad.

Onagers is at least 400 years beyond the timeline. Ballistae were too large to be placed on a wall or inside a tower. However, the late Sir Marsden speculated that the towers at the ruins of Ephesus (Greek ruins in SW Turkey), could have accomodated the katapeltai oxybeleis (spear thrower) and perhaps some small stone-throwers (katapeltai petroboloi). Still, this is pure speculation.. the best place you could have a counter siege artillery at would be behind the walls, not ON the walls. Siege artillery was not yet powerful enough to be warranted such a common role. Ancient siege artillery took a lot more time to do its magic than medieval siege artillery did. Counter-artillery would certainly be useful for getting the enemy siege towers. The besieger had to prepare a 'runway' 2 weeks before he could roll up his siege towers. This was done under small rolling shelters known as "chelones" (latin: testudo). Shelters on wheels. They would have workers underneath these shelters filling in any ditches, removing any lumps on the ground.. flattening it all. Thus, the defender knew precisely where the siegetowers would come, and could align his artillery perfectly, in good time.

However, sapping is something which is more prevalent. And it's here there should be some form of counter-sapping. But I'm afraid the hardcoded nature will make this difficult. Not to mention the sapping happens too quickly.. it tooks weeks or months to dig - these were not molemen, they were just men.

The romans usually just used ladders. Or sometimes, like at Lilybaeum in the 2nd punic war, and Alesia, they used circumvellation. This was inspired by the greek Periteichismos (encirclement) of the Peloponnesian Wars in 413 BC.
The Romans did another thing very often. They worked under rolling shelters to make ramps of dirt up to the walls. These very tiny rolling shelters were like segmented "worms" of shelters lying on the ramp. These shelters were called "vinea". And so, they just built a ramp of dirt up to the enemy wall and walked right over it. The non-fancy "brute force" theme usually comes up with the Romans as you would have noticed. Very little siege artillery was used at all by the Romans. All they did was to capture Carthaginian and Greek siege artillery, they never constructed their own artillery in a standardized fashion until the time of Vitruvius (Caesar's engineer).
