Built-in multiplayer with Playroom.

How it's built?

This starter is built with SvelteKit and uses the Three JS 3D library and the Rapier physics engine. The multiplayer is done using Playroom. Why SvelteKit? Because you ship fast 👇

    <script>
        let count = 0;

        function increment() {
            count += 1;
        }
    </script>

    <button on:click={increment}>
        Clicked {count}
        {count === 1 ? 'time' : 'times'}
    </button>
