Hello, my name is Álvaro. Thanks for read me. I'm learning Unity since 2 years ago. I'm making a simple RPG game and I hope to set-up to online gameplay in the future. I don't have enough familiarity with online set-up and I understand that it can be so hard... but: I'm making libraries and random info like objects that you can loot from different boxes in game. Or NPCs loot and something like that. My question is: what I must to know about "un-hackeable" and saving data files for my game? I don't want make the online set-up tonight but I think that I must know how is the best way for make an useful game for my future needs. Can you recommend me manuals, info, examples or videos for understand how i must work right now? Really thank you so much. EDIT: Only I want to say that my game is developing so so nice for me, your information will help me for work healthy and self confident today and in the future!
