How have you defined base objects in your game? (sh.itjust.works)

I'm making an RPG in C++ and the items (loot/gear) will have immutable base versions, but then the player can get instantiations of them which can change with use and modification. These mutable instantiations will be saved in the DB. But I'm wondering if the base versions should be defined in JSON, or a separate DB (with the same schema), or maybe the same DB (seems dangerous), or if I should just hardcode them in C++ in the ItemFactory.

How have you approached this problem in your games? How do game engines do it? I'm using SDL2 so I'm doing most of these systems from scratch.

Pretty much, yes. I generally have such few item types in my game that it doesn't really matter if I hard code them.or not.

For example, Item might contain parameters like item-id, item name, carry weight, etc. Parameters that every item would need to have. Then HealthItem would inherit from Item, and thus would include all its base parameters and methods for being added to the inventory, etc. HealthItem would then also have new parameters like heal-amount and a method for healing its user.

Something like a health potion that heals 5 health and a medkit that heals 50 health would both use the same HealthItem class, and be stored in the game engine as separate prefabs. These prefabs would then be instantiated into the game for entities to interact with them.
