.NET Terrarium 2.0

New Post: project status?

bsimser — Fri, 03 Jul 2009 13:15:34 GMT

Hi sarmaad,

Yes, the wiki and server are up and running (just checked to be sure). There are still some bugs ;) with the server (namely I think the peer count bug) which is causing problems with client interaction but a) you can upload your bugs to the central server and they will run and make it into the eco system (you can see the stats on the server website as there are many bugs that have been uploaded) and b) you can run your bugs inside of your own local Terrarium.

What isn't working right now is downloading bugs to your local machine from the central server.

Hi Matt,

Yes, there was a bit of a hiatus but things are rolling again. There are many people interesting in the project and a few have already submitted patches (which are available in the latest changesets). Work is still needed to get it running under Vista, however there are workarounds to get it running if you want.

bsimser — Fri, 03 Jul 2009 13:11:25 GMT

Plants are boring and have very little capabilties (other than to breed). Sorry but the advanced developer guide was written by Microsoft and I haven't had a change to go through and either a) remove anything they wrote that they didn't implement or b) implement what they spec'd out.

There is a plan to make plants more interesting and useful. Right now just create one using the guide (there are samples on the wiki too) and plop a few in your Terrarium to keep your animals happy. Remember that you need plants to feed the herbivores, and herbivores to feed the carnivores in order to get a full cycle going and keep the animals alive.

For the "Dead Organisms" issue see http://terrarium2.codeplex.com/WorkItem/View.aspx?WorkItemId=13593 and patch 3231.

Patch Uploaded: #3231

timerickson — Thu, 02 Jul 2009 05:50:23 GMT

timerickson has uploaded a patch.

Description:
Another fix for the "Dead organisms can't move" problem when trying to add organisms in either Terrarium or Ecosystem mode.

Property initialization for EnergyState and Radius are pushed down into the OrganismState constructor, and a work-around is introduced to avoid the EnergyState setter chicken-and-egg scenario by setting the energy field directly (not via the StoredEnergy setter) via an explicit private SetStoredEnergyInternal method.

Further the UpperBoundForEnergyState method is made static, as it is not instance dependent, thus clarifying its use.

For rev 35084

Created Issue: Adding organism results in "Dead organisms can't move" exception message

timerickson — Thu, 02 Jul 2009 05:34:00 GMT

Adding any organism in either Terrarium or Ecosystem mode results in "Dead organisms can't move" error message.

This message arises when, in the InitializeNewState method of both PlantSpecies and AnimalSpecies, an attempt is made to IncreaseRadiusTo a value when StoredEnergy == 0. This method and many others throw an Exception if attempts are made to change OrganismState properties while IsAlive == false. This includes the setter for EnergyState. EnergyState is initialized to the default of 0, so there is a chicken-and-egg problem.

Updated Release: 4.0

bsimser — Wed, 01 Jul 2009 22:04:47 GMT

Major upgrade with breaking changes. There will be no upgrade path (except to recompile your organisms with this release).
.NET 4.0 platform build
DirectX sub-systems to support Vista x64 and Windows 7 x64
WCF service rewrite
WPF client rewrite
New ServerConfig, Server Installer and additional tools
ZBB (zero-bug-base) release to clear up all outstanding issues

Created Task: Move codebase to .NET 4.0 platform

bsimser — Wed, 01 Jul 2009 21:56:56 GMT

Yup, time to get off the pot and update this to the latest and greatest. Breaking changes as it'll break any existing organisms but it has to happen for the sake of progress (and to get off the legacy codebase once and for all)

Created Issue: Rebuild web services using WCF

bsimser — Wed, 01 Jul 2009 21:54:50 GMT

The existing web services were built pre-1.1 days. Time to rewrite them as WCF services for the .NET 4.0 platform.

Hi guys,

With a recent tweet by Scott Hanselman (thanks Scott!) there's been renewed interest in the project. So with that we're looking to fix up some lingering problems and shift the light on Terrarium to some new technology.

The original release was for .NET 2.0 but since then it's been recompiled on 3.5 and some effort has started on creating WPF versions of the client.

Hopefully if I can get some help from you guys there's a few things we'd like to get going on:

Update to .NET 4.0 platform. The code *should* compile on 4.0 but I haven't tried it yet.
Update to WPF. Ditch the old WinForms legacy clients and finish the WPF ones on 4.0
Redo the web server in ASP.NET 4.0 MVC with the new 3.5 charting controls. The old web server was such a hack and butt-ugly ASP.NET 1.0 code.
Update the web services in WCF to be consumed by the new website and clients.
Fix the x64 compatibility issues and get it ready for Vista x64 and Win 7. This would include looking at maybe folding in the recent managed DirectX wrappers from MSDN Code Gallery and ditching the old legacy wrappers.
Launch and try to get some new organisms going and grow our community!

Like I said, hope we can move towards this soon and I'm looking for you to help out. Download the current codebase and take a look then contact myself or Scott Hanselman if you're interested in taking on some tasks.

Thanks!

Hi.
r24268 causes that error.
r20104 doesn't.
I tested it by replacing "/Client/OrganismBase/" directory with specific svn revisions.
Sorry I don't understand what's wrong between them.
Thanks.

Commented Issue: Item has already been added. Key in dictionary: '44011' Key being added: '44011'

kkdf2 — Sun, 14 Jun 2009 08:09:39 GMT

im getting this issue a lot, if i try to check if it contains the error is pass to the next function, so checking if the key exists or not was not the solution: this at

SortOrganismsForDisease...
.
.
.
if (!((AnimalSpecies) organismState.Species).IsCarnivore)
{
if (animalsToKill.Contains(speciesName))
{
addList = (SortedList) animalsToKill[speciesName];
}
else
{
addList = new SortedList();
animalsToKill.Add(speciesName, addList);
}

addList.Add(strength, organismState); ///// <- Exception here
}

Hi.
I also encounter this problem oftenly. And Terrarium gets terminated due to Exception.

It may cause when over 400 creatures are in the terrarium.

Sorry. I don't know how to solve it.

timnew — Thu, 30 Apr 2009 16:43:23 GMT

Yea, I didn't find any plant too. So my poor creatures are all starved to death, yea, they're really dead.

I noticed there are some sentences in the doc named Advanced Develop Guide said that "Plant Eats Sunlight"?!

And I tried write some plant, but it doesn't work at all.

So can you give us some hints about the plant problem

Hey,

I would like to help out with the project. Is it still going? i noticed that there haven't been any code changes since december last year.

I have some experience with XNA, and a lot of experience with WPF, and .NET in general. Where can i help?

I would really like to see it running under vista (because that is what i am using at home).
