Hey man, how's it going?
I haven't done all the tests yet to see them working together, but at first glance, none of the examples you mentioned handle the same classes within the RPG Maker engine, maybe CraftEnhanced and REInventory a little bit since they both handle inventory, but I can see them all working together.
Anyway, I'm committed to making the necessary corrections and adaptations to make this plugin ecosystem work harmoniously.
In a few days, you're releasing a new version of ShootingGame, more complete and with suggestions from the community.
I tried to run some tests until then to see what already guarantees compatibility for this upcoming version.
I'm excited about your idea, I hope you can meet all the requirements.
