What’s the configuration file solution for Unity for example: ini, json or xml based. I’m looking for a solution can store at least string, int, float and would be good to support array, key/value directory. Also the ability to easily overwrite some keys. For example if I load default.conf and production.conf by order, the later one will overwrite previous value.
If you just want a config file to load at runtime you can store any plain text file format as .txt files in your resources folder of your project and parse them in scripts. There are implementations of json and xml floating around.
If you want to modify the config in your game (not in editor) then PlayerPrefs is the most cross platform method of serializing information.
