Running a game server
Moddio will run games made using modd.io game editor.
To run the game server, execute the following command:
npm run server
*The engine will use game.json stored in /src directory.
You can download Game JSON from your modd.io's game's in-game editor. Go to Editor -> Click Export JSON.
Alternatively, you can download Game JSON from your modd.io's game's sandbox. (example). Go to Menu -> Click Export JSON.
Next, rename the downloaded Game JSON as game.json and move it to the ./src directory.
