Question about modding buildings

[King Dave]

Hi guys, I would like to know how I can mod buildings in the export_descr_buildings.txt. What I would like to do is make ballista ranges, catapult ranges, and siege works only buildable in castles. I have already tried editing this part out:

building siege
{
convert_to castle_siege
levels ballista_range catapult_range siege_works
etc

and just leaving in:

building castle_siege
{
convert_to siege
levels c_ballista_range c_catapult_range c_siege_works
etc

And no success, the game wont start up now so this is the wrong way Could someone be kind enough to explain exactly what I need to mod and what lines would I need to change. I have already tried looking for tutorials on how to do this but cannot find one.

Can't test this myself, at work, but the game is very
fussy about consistancy. Since you modded out the
building siege, try removing the convert_to siege
line and see if it works.

Hi, I have tried removing the convert_to siege line, but this also does not work either. The game still crashes when I try to load up, thanks for your help anyway.

Does anybody know how I can mod siege buildings to be only buildable in castles? This would help cut down the amount of siege weapons the ai keeps on spamming..

Also try enabling error logging (as described e.g. here)

Well the game just wont load up with my modded export_descr_buildings.txt, and doesnt show anythink in the system.log.txt. So Ive put the original EDB back in for now and the game loads as normal again.

Ive found out how this works now if anyone else needs to know this info. Its quite simple, delete all of the following

building siege
{
convert_to siege
levels c_ballista_range c_catapult_range c_siege_works
etc

then when youve just got the castle part left you edit the top line building castle_siege to building siege as shown below.

building siege
{
convert_to siege
levels c_ballista_range c_catapult_range c_siege_works

and thats all it is
