Running the game

Make sure you have Node 18 or later. First, setup the repo

How do I create a new game from scratch?

Moddio games are created & edited using Moddio Game Editor available at https://www.modd.io. To learn how to use the game editor, visit https://learn.modd.io.

Once you create the game, you can export the game.json which you can use in your local installation. Inside the Moddio Game Editor, Go to Menu -> Click Export Game.

Next, rename the downloaded Game JSON as `game.json` and move it to the `./src` directory.
