## Running the game
Make sure you have [Node 16](https://nodejs.org) or later.
First, setup the repo
```
git clone https://github.com/moddio/moddio2.git
cd moddio2
npm install
npm run tsc
```
Then, to start the server run:
```
npm run server
```
You can now play the game at http://localhost:8080
## How do I create a new game from scratch?
Moddio games are created & edited using Moddio Game Editor available at [https://www.modd.io](https://www.modd.io).
To learn how to use the game editor, visit [https://learn.modd.io](https://learn.modd.io).
After creating your game, you can export the `game.json` file for use in your local installation. To do this, navigate to `Menu` in the Moddio Game Editor and click `Export Game`.
Next, rename the downloaded Game JSON file to `game.json` and move it into the `src` directory.
To load your game file, simply start the server by running:
```bash
npm run server
```
You will be presented with a dropdown menu, where you can use the arrow keys to select your game file. Alternatively, you can pre-select your game file by running:
```bash
npm run server --game=game.json
```
