[Request] Technology tree modification tutorial

**Dingkuhn** · May 31, 2015, 12:21 PM

Hello fellow modders,

I'm not sure if I'm getting right how to modify Attila technology trees.

Basically what I try to do is to replace technology x, which is common to two different trees (i. e. factions), by technology x_faction_1 and x_faction_2; so that an unit common to both factions can at some point (i. e. after that either technology x_faction_1 or x_faction_2 has been researched) be upgraded into two different units depending on the faction you're currently playing.
As a result I added and modified the five following tables in my pack file: technologies, technology_effects_junction, technology_node_links, technology_nodes and technology_unit_upgrades; but the mod is still not working (launcher freezes = infinite loop = information missing = table missing or typo(s)).

Now my questions: did I forget to add and edit one or more tables? Do you know any tutorial explaining how to mod technology trees in Attila?

Thank you

be sure you check this table too

"effect_bundles_to_effects_junctions_tables"

I checked it, but I don't think I need it because my new technologies have basically been copy/past from the vanilla ones and aren't supposed to produce a different effect. But thank you anyway

oh this is such a big mod, it's hard to find the problem
you sure only technologies part causing problem?

btw so you added new technologies to some factions (or replaced) where they will take place?
isn't UI expanding also needed?

I tried to run the mod without the technology tables and it worked out fine, so I assume that the problem really comes from there.

I actually didn't "add" new technologies, but did that kind of thing instead: get rid of att_roman_military_billiting in the technologies table and replaced it by att_roman_east_military_billiting and att_roman_west_military billiting. In this case the UI is supposed to stay the same as in vanilla.
