OCaml Text Based RPG

This is a very rudimentary text based RPG built in OCaml. The "game" part is in rpg.ml while the rest of the core mechanics lie in other files. This project was originally created to be extensible and modifiable similar to a game engine. If you peruse through the rpg.ml file, you can get the basic idea of how a game built in this engine is structured.

Cool features:

• Quadtree room storage (see quadtree.ml for implementation) - Room addition and lookup are O(log n) time with O(n) worst
• Undecided option - Various components in the game can change based on the current state with a fancy "Undecided" option that returns a Some or None when the function it holds is run
• Functional - There are no for loops, while loops, or classes in this project. Only recursion and algebraic data types!

To run this, you need OCaml and ocamlbuild installed.

Potential extensions:

• More than one interaction per room
• Elemental weapons that deal more damage to weaker typed monsters (fire sword critically damages plant monster)
• Shopkeepers with limited inventory as part of room interaction (also where you can sell loot items)
• Interactive puzzles similar to how monster battles work (solve a simple math or word puzzle)
• Weapon durability (Weapons break after a certain number of uses or battles)
• Health potion items that do not overflow health over a certain maximum
• Leveling and experience: killing monsters -> get experience, progressively more experience -> level
• A map command that prints all visited rooms in a grid (not a list of coords)
• Saving to file, Loading from file
• Battle more than one monster at a time
• Checkpoints to return to when the player dies
• Mining resources / farming: ore can be mined, plants can be picked rate limited by real time
