You've loaded an old revision of the document! If you save it, you will create a new version with this data.

====Groworld multiplayer prototype====

An initial version of the groworld game in order to have something to focus on and develop ideas further. The main priority is to demonstrate some of the techniques we want to explore in the simplest possible form.

* Network communication protocols/transport
  * Multiplayer gameplay
  * Basic plant communication (via pollen)
  * Exchange of simple properties/behaviours
  * Plant ownership/point of view

Use [[pluggable plants]]

====Network protocol====

===OSC version===

The osc version works in a peer to peer manner in that there is no central server, and clients need to pass information around to each other. This has only been tested with 2 clients... Each client has a notion of the plant it 'owns'.

When joining a game, you need to create a unique id for your plant. With no central server, this currently works in the following ad-hoc manner:

- Broadcast /join-game
  - Wait for 2 seconds, deal with all incoming /plant messages
  - Count the number of plants, give yourself an id based on that
  - Broadcast your new plant back with /plant

===Structure information===

Currently an sexpr as this is what the pluggable plants system uses rather than l-systems. I need to have a think about this...

Each component looks like this:
<code>(texture-id list-of-children)</code>

A real example:
<code>((1-1 ((3-1 ((1-1 ((1-1 ((11 ()))))) (2-1 ((2-1 ((11 ()) (11 ()))) (1-1 ((11 ()))))) (2-1 ((2-1 ((11 ()) (11 ()))) (1-1 ((11 ()))))))))))</code>

The numbers refer to the texture naming convention for [[pluggable plants]].
