Hello. I think my better way to start is to know where is a spanish forum, or spanish people to talk.
Also, I would like to know how, in FEW steps, create a basic program, from start (very simple guide of commands and program structure, simple editor, where test my basic program, and how get the .EXE program for use it in my PC … to the end (for other people to use that program, for example placing my program in somewhere and then the Internet people can run it at his browser).
Anyway, simply get the spanish forum and a very very very simple guide to mak a program, NOW (10, 20, 30 minutes and, in all cases, without problems of understanding).
Welcome! I don’t know of any dedicated Spanish-speaking forums, unfortunately. English is pretty much lingua franca in the programming world, and consequently most sites are built around it, too.
You can absolutely feel free to post here in Spanish, though. It’d be great if you could write in English as well (your English is great, from what I can tell!) so dum-dums like me can still try to help, but I’m sure we have Spanish-speaking members here who can help if you prefer to only communicate using that.
I don’t have any shortcuts to getting started, other than checking out Unity Learn. I don’t like the new structure as much as the old one, but that might just be a side-effect of getting old rather than a comment on the quality of the site. It might seem like it’s a lot of steps, when you’re just looking for something quick to get you going, but if you think about it, it makes sense that it’s complicated… You’re learning how to use a pretty powerful game engine here!
Once you actually publish something, itch.io is a great site for hosting game content. It’s free, popular, and simple to use.
Let us know if there’s anything specific you’re getting stuck with. We’re always happy to help.
