From http://croquetproject.org/Croquet_Technologies/architecture.html

Since real objects (As opposed to so-called “objects” in many so-called “object languages” which are actually data-structures with procedural attachment and don’t really encapsulate and use messages for communication) are by their definition protected, and must receive and adjudicate messages-events to initiate processes that might change their state, we can also keep a message-event history that keeps track of the ordering of the messages as they are issued and received. Get in there Alan.

And this mind bender.

The second kind of simulation is usually used for managing more complex behaviors, those that can't easily be captured by trying to recalculate the state of the world from some time in the past. This is done by literally having the object send a message to itself in the future.

They also mention my other academic interest at the moment integrated with a capabilities-based security system such as "E"

This time I want to be ready for the land grab, anybody fancy helping start the First bank of WonderLand?? http://www.mebsuta.com/alicemoney.htm -- OliBye

Here's my first little dablings in OpenCroquet (the Teapot Morph) I love it. I'm going to see what my little brothers think.

It really is very beautiful inside, I've upgraded my graphics card to a cheap 100 GBP nVidia GeForce4? and things are pretty smooth. https://xpdeveloper.com/~byeo/images/xptea.jpg

I've now made a world that shows the state of our SMSC connections. Little clocks move up and down, change colour and show how long they've been idle for. It's really very simple to do, I'll upload the change set soon. I'm having fun learning about the compositional nature of adding behaviors to objects. Decorators seem MockObjectsAndDemeter friendly so far.

That's so cool --SteveF

Looks nice, but what is OpenCroquet?

Reminds me a bit of the IncredibleMachine?, where the concept of object, behaviour and graphical representation blur. Any idea where we can get a download whilst OpenCroquet is not online? -- PaulS

I'm begining to find that the 3D side of OpenCroquet is really a distraction, as all this functionality existed in the sqeak Alice layer. The real stuff they've worked on is the distributed aspect of sharing a 3D space. This side of things is still at the alpha stage. -- OliBye

The first release, "Jasmine" 0.1 is out now: http://www.opencroquet.org/Croquet_Technologies/downloads.html

They said: "...This release is aimed at experienced self-sufficient software developers who are comfortable working with unsupported software with minimal documentation. You should be prepared for the possibility that parts of the system may not work, and that programming interfaces and the software structure may change as the system evolves towards its alpha and beta releases..."

Ho humm. Another day at the office ;-)

Jasmine is the first release where I've managed to get the networked aspect of OpenCroquet working.

1. Start Jasmine on two machines on the same network segment (TCP broadcast used for discovery)
2. Make sure you're up to date with changes (~10 a day come out)
3. Start a the TeapotMorph? of your choice. My laptop is only up to the TestTeapot?
4. On each machine move the mouse to the bottom of the window to display the menu, then select tools and connection. Then select connect. The options make little or no difference.

Alan Kay demonstrated OpenCroquet in his Turing Lecture at OOPSLA 2004.
