UNO

A synced multiplayer UNO table for 2 to 10 players. Made for SideQuest / AltspaceVR worlds, and it also works in Banter.

There is no server: players stay in sync through the space's shared state, and the game is plain static files served from https://uno.firer.at.

To try it, open https://uno.firer.at in Altspace or Banter.

Features

• Skip, reverse, draw and wild cards
• Hands and turns handled for you
• Host migration and disconnect handling

Add it to an Altspace world (snippet)

In a Creator SDK world, add an empty GameObject at the origin, click Add Component > BS > Snippet and type uno. Or paste this into Assets/WebRoot/index.html, between the snippet section comments:

<!-- snippet section -->
<bs-snippet name="uno" title="UNO"
  description="Synced multiplayer UNO table."
  script="https://uno.firer.at/snippet.js"
  room=""
  position="0 0 3"
  rotation="0 0 0"
  sound-volume="0.4"
  sound-near="2.5"
  sound-far="10"
  debug="false">
  <bs-gizmo type="position" attribute="position"/>
  <bs-gizmo type="plane" attribute="position" size="3.2 3.2" rotation="90 0 0"/>
</bs-snippet>
<!-- end snippet section -->

• Each placement is its own game. Its sync id is room, or the placement's own id when room is empty. Give placements the same room to share one game.
• position and rotation are Unity world values. The other settings are listed under Settings. An empty setting uses the default.
• The Scene-view gizmo shows the table footprint.
• Unity reads the snippet section as XML: quote every attribute, close every element, and write & as &.

Add it with a script tag

This works in an Altspace world's Assets/WebRoot/index.html (outside the snippet section) and in a Banter space's HTML:

<script src="https://uno.firer.at/uno.js" position="0 0 2" rotation="0 180 0" instance="lobby-uno"></script>

For more than one table in a space, give each one its own instance:

<script src="https://uno.firer.at/uno.js" instance="table1" position="-4 0 0"></script>
<script src="https://uno.firer.at/uno.js" instance="table2" position="4 0 0"></script>

Settings

Setting	Also accepted	Default	Description
instance		demo-uno	Sync id. Tables with the same id share one game. In a snippet, use room instead.
sound-volume		0.4	Volume of the sound effects, from 0 to 1, heard at full strength near the table. 0 turns them off.
sound-near		2.5	Distance in metres from the table within which the sounds play at full volume.
sound-far		10	Distance in metres at which the sounds have faded out completely, so people elsewhere in the world aren't disturbed.
position		0 0 0	Table position (x y z).
rotation		0 0 0	Table rotation in degrees (x y z).
debug		false	true logs extra detail to the console.

How to play
