Hi all, so essentially what I am trying to do is use this effect function giving it an input of a buildable pop, like robots. That doesn't seem to work, either via using the name in the class or the defined class name like buildable_robot. This begs the question: exactly what is the input? I've seen solutions by other modders to create a new species and then supply that species as an input and it works as expected, however what I am trying to do absolutely requires use of a pre-scripted species like a buildable pop rather than one created on-the-fly. Interestingly, the add_species_trait (or something like that) console command does work, but only when I supply the species index value found in the save file. Neither the class or class name supplied work for that console command, and the species index is highly variable depending on how many empires exist, making it an unreliable input. Is there any way that this can be accomplished in the current state of the game or will the developers be required to implement this sort of functionality?
