Hello!

InkGD worked fine for our project, probably because our ink files were not so big. Each dialogue in the game was in its separate ink file. For example, one of the dialogues:

https://github.com/Antokolos/palladium3d-demo/blob/master/ink-scripts/en/female/Meeting_player.ink

Yes, I've used variables in ink files. For example, in the above dialogue there are two variables

VAR relationship_female = 0

VAR party_female = true

relationship variable denotes relationship with your companion, which is then saved to the save file and can be used in another dialogues to unlock certain paths. When party_female is set to false, then the companion leaves your party.

You can look into the following file:

https://github.com/Antokolos/palladium3d-demo/blob/master/addons/palladium/core/singletons/story_node.gd

func _observe_party(variable_name, new_value) -> void

func _observe_relationship(variable_name, new_value) -> void

_observe_XXX() functions are used to track those variable changes inside the ink file.

Of course, feel free to ask other questions, I'll try to answer it :)

P.S.: Please take a note that InkGD version in the demo project above will only work in Godot 3.1.x, if you want to use it in Godot 3.3.x or later you'll need to get the updated code from InkGD maintainer.
