This is a unique AI-based pet plugin. There is a lot to explore in the documentation and after some testing, you can have pets that are far more interactable than vanilla counterparts. They are great companions in combat. The lightweight jar installs with a simple drag-and-drop, auto-downloads its own database drivers, and defaults to YAML while staying ready for SQLite or MySQL. In game, 12+ behaviors—Guard, Hunt, Scout, and more—shift on the fly as eight emotions (hunger, energy, affection, happiness, trust, loyalty, fear, anger) rise and fall, so pets act alive instead of scripted. They gain XP, unlock skills, and evolve into stronger forms—all managed through sleek GUIs. Compared to the usual follow-and-fight companions, these pets feel closer to party members with moods, making SmartPets an easy recommendation if you want companions that act—and react—like living creatures.
