Undestroyable buildings II

[Giurza]

Could anyone tell me how I can set a building undestroyable or on the contrary remove this characteristic and make it possible to destroy it (for example a town wall or stockade)? Or, in other words, when creating a fully new building in the game compared to vanilla RTW (in DTW a "colony" for example), how it can be set that this building shall be undestroyable? Thank you a lot!

and the answer:

The keyword 'hinterland' at the beginning of a building name.

come from Diadochi TW thread
my question is actually a call for a more in-depth knowledge -
walls have no such word in front of them - how do I make 'em destroyable (and most important - does it potentially causes CTD)
core buildings - the same question
what files need to be edited (except export desc buildings) and how exactly?

Anything that changes the appearance of the stratmap cannot be made destructible (except ports for some reason), it's a hardcoded part of the game.

So governors residences, walls, farms, mines and roads cannot be made destructible.

Farms and mines can be worked around a bit by creating completely new types of buildings that use different building attributes to give a similar effect, but it doesn't work 100%.

thank you for the answer. sad though, I wanted to get rid of the walls most of all... mostly because it would get me a more challenging campaign without going on VH/VH...
