Ninja'd!I was hoping to see something like this! I love the idea of N Terraria's Npplayers, being able to make one of our other characters an AI teammate, and kind of hope a version of it comes to us someday, but I use a lot of tModLoader stuff and don't want to abandon it.
Maybe for something simple, a couple monsters could be converted into TerraGuardians, like a lamia or chaos elemental, unless they can only be big like Rococo. Still reading through things here.
Oh! I don't know if there's a way to heal a TerraGuardian but maybe making it compatible with Thorium's healer equipment would be nice.
Well, It would not be possible to make npplayers mod with tModLoader, due to the fact that they would behave like the other players in multiplayer, being immune to anything, and only hooking few damages. That unless several changes were done on tModLoader source itself, and since I don't want to make the developers pull their hair trying to make it possible for me to make the Npplayers, I created my own character system, which is independent of the player, npcs and projectiles, at the cost of literally having to "recreate" them.
As for the idea of making some Terraria monsters into TerraGuardians, that's actually a good idea, I kind of thought about that possibility, even more since they aren't restricted to being big like Rococo is (Actually, If I mess with the system codes, diverse sizes of TerraGuardians can be possible, from extra small to giant ones).
As for healing them through mod stuff, currently that isn't possible, It would be necessary to add compatibility to Thorium mod, but currently I'm still developing the mod systems, so there isn't much of a time to add compatibilities. I even were wanting to add Terraria Leveled compatibility, so the Guardian could catch up with my character.
