Create arrays, look into structs - they’re collections of variables. You can nest struct arrays inside other arrays to store any amount of variables. Look into save games objects. You will need to save your game eventually, structs are pretty much a must here as well - that’s unless you want to use external plugins.
Data Tables are read-only.
Is there a proper way to store a table
of data or do I have to botch it
together by holding all of the data in
a string that contains some character
or to read specific parts during
runtime?
Again - structs.
