I would like to create a game similar to what once was Treasure Isle from Zynga. I have no idea where to start. I’ve been scouring the site and googling, but with no luck so far
You should begin your Unity adventures here: Learn
I always find it best to create a development plan before starting to make a game. This was I have a rough idea of gameplay mechanics, level design and story.
Once you have all that written then the next step is to create a basic scene in unity where you will create gameplay mechanics such as health, inventory, movement etc etc. This is where you will need to search Tutorials specific to the mechanics you will have in game. YouTube is fantastic, I recommend Brackys.
If You are working alone then I recommend using free simple assets when creating a basic scene. It’s a “how it should work / kinda look” in The most basic sense.
If you wish to create your own models then learn Blender 3D as that is free.
Hope this helps
A lot of people start with a single game in mind, but really, you should try to stay open when you start and do lots of tutorials in all kinds of genres. Then do some simple games on your own. Then start on an advanced project. You really need some background on how games work before starting on a large project, and the one you do will probably be a lot simpler than what you have in mind now.
Learning the basics will allow you to work from the ground up, and understand what you’re doing more completely.
Someone who has a very simple game, but understands it completely is, in my opinion, further along than someone with a more complex game, who cannot understand a single piece of it (as it was copied over).
~ just as an example.
To add to what others have said, keep in mind that creating a game of that level of complexity is no simple task. The art, music, coding, general design and planning, and creation and testing of all the mechanics both alone and interacting with each other is a huge amount of work. You’re likely looking at a several years long project. If your’e really determined though it’s doable. Just be sure you’re ready to commit many thousands of hours to it. If you’ve never made a game before I advise starting with simple things and working your way up to more complex games by combining what you’ve learned on previous projects.
