Seaside 2.9 and Comet to control replicated Croquet islands.

I want to share some of my experiments in combination of Open Croquet and Seaside/Comet at image level.

The main aim is: to allow multi-user interactions with shared content on the Croquet island just from web browser in real time (from any place, device like smart-phone, low-end machine (sometimes without OpenGL) etc. so, that a connection to the network and http web based browser just needed.
Also, it could help to implement open source "Forum pages" like features , which are existed only in Qwaq forums 2.0 (access recent activity from your web browser etc.).

I have prepared the ready-to-go image for those, who want to explore the infinite possibilities :)
1. CroquetSDK.v1.0.18 with new image.
2. Just one image for using with manual downloaded any Croquet SDK.

Also, I prepared the Script for loading Seaside 2.9 alpha updated (13-07-09) into any fresh OpenCroquet image (1.0.18 users should update from sources to the latest, or use this one Croquet.1.0.25 )

For examples look at SmotriniWorldControl class.


Here on the screen-shot there are two participants and two opened web browsers (Safari, Firefox).
Just only one participant run Seaside/Comet application.
Changing any of the RGB sliders (in one of browser window) causes the change of the active space color, and glad to Comet in all opened Web browsers slider's handles change their visual state automatically (without manual refreshing).

All callbacks from seaside to croquet island are future events, like from proper harness in Croquet, so they dose not destroy the replicated state.

onSlide: (html jQuery ajax
callback: [ :value |
aColor = #red ifTrue:[self class valueRGB red: value asNumber.
aFrame future color: (Color r: self class valueRGB red g: aFrame color green b: aFrame color blue)].

How to run:

1. Start WAListenerAdaptor (support Comet Seaside applications)

WAListenerAdaptor startOn: 8888. (different ports for several participants, if needed)

2. Open Croquet master (KAT Demo harness is used in this example, from default Croquet SDK).

KCroquetParticipant new openInWorld.

When it asks about interactivity server, leave it blank, as (www.croquetcollaborative.org) could not work, so it will start locally.

3. Point your any web browser (Firefox, Safari preferable) to:

http://localhost:8888/seaside/croquet

4. To test Comet functions (RGB Slider), just open another browser window and point it also to:

http://localhost:8888/seaside/croquet
