Okay, I need some help from modders who know how to add buildings to the battlemap.

I am trying to add the BI-buildings to my mod. I have done every step from any forums, but I still got the same error.

I am working in a modfolder, and I have every item and building model copied etc. The final step however is not working and is very irritating.

I need to create the descr_item.db for the new buildings in my modfolder. When I just copy the descr_item.db and descr_item.txt from BI, the game starts. But when loading the new buildings on the map, I get lot of errors (the models are not found). However, after loading the city, all BI buildings are present, but the normal RTW buildings are gone.

So I decided to create the descr_items.db on my own, which leaves me with another error.


Having only the descr_items.txt, which contains:

Code:
; spot items
include di_spot_items.txt

include di_slot_fillers.txt

include di_wooden_walls.txt
include di_walls_roman.txt
include di_walls_greek.txt
include di_walls_eastern.txt
include di_walls_egyptian.txt
include di_walls_barbarian.txt

include di_nicks_roman_buildings.txt
include di_nicks_egyptian_buildings.txt
include di_nicks_greek_buildings.txt
include di_nicks_eastern_buildings.txt

include di_barbarian_buildings.txt

include di_wonders.txt
include di_foliage.txt

include di_kevins_buildings.txt
include di_bens_buildings.txt
include di_andrews_buildings.txt
include di_pauls_buildings.txt
include di_johns_buildings.txt
include di_joss_buildings.txt

include di_roads.txt

include di_animals.txt

include di_gates.txt

include di_ambient.txt

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

include di_barbarian_invasion.txt

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
the di_barbarian_invasion.txt is in the descr_items folder.

When I start the game I get this error:

Click image for larger version.

Those files are not in the descr_items, and they are neither in the vanilla rtw folder. Where can I find those files?

Please help I want to add buildings myself later
