naval artillery question

[Kutkaboutert]

there are ships with for example archers on them and scorpions. These scorpions are in the table naval_weapons, and thus they are different then the bigger naval artillery, which are described in the main_units table. I want to know if it's possible to create onagers and ballistae for the naval_weapons table, so that I can equip ships with an onager of ballista while putting archers on them.

Allright, I got it working. I've got another question now though, is there a possibility of giving an autonomous engine a firing cone?
