json.lua VS classic

One option might be to look at the Path of Building “Data” folder. If you need them in another format (e.g. json), it wouldn’t be that hard to write a Lua script to export them in your preferred format (using this json library, for example.

If you don't want to reinvent the wheels, you might want a json encoder to transform data into strings and back. Or bitser if you want better performance and smaller files in exchange for human-readability.

Honestly, I just went with JSON because there's a nice Lua library for it (thank you https://github.com/rxi/json.lua).

I haven't thought about the file format much so far, just the experience of writing in it as if it's the "ground truth". We all seldom open our text files in a hex editor.

Get json.lua from here. Put it in your project directory alongside file1.lua.

Good point. How about this? It allows you to encode/decode Lua values into/from JSON.

I like this json library and tend to use it for save files (also makes them easy to edit by hand while debugging). It gets angry if you use tables with a mix of string and numerical keys, but I'd advise against that anyway. I've also used binser, which is also effective and easy to use.

lua json module can be found from here: https://github.com/rxi/json.lua

Once they grasp some lua basics and I've actually got a little code running but before I do much to make a game. I'd suggest you give them loom my fork includes the documentation with the code. Also a class system either a basic but easy to understand or more featureful.

I can't criticism your implementation at the moment but I want to share a tiny class module for Lua as a inspiration. https://github.com/rxi/classic

(this example uses classic, which is a library I like using for OOP to keep things simple)

I like classic over middleclass: https://github.com/rxi/classic Feels lighter weight, like barely anything.

You can do oop in Lua too! You just need a class lib.

I'd recommend spending a bit of time with the readme for classic: https://github.com/rxi/classic

Get as simple as possible OOP library, for example this one and write some code using it. This library can inherit ordinary functions, but not any metamethods. Try to improve it. If you can implement metamethod chaining inheritance that allows you to __call an instance of inherited classes like a function, then you understand metamethods thoroughly. Even if you fail, it still will be a good practice.
