The tutorial is based on Kolipoki's original object modding tutorial, so kudos to him!

Great! That tutorial needed updating.

For some reason, I can't add the mscorlib.dll as a reference, even after checking Do not reference mscorlib.dll.

That's a known bug in Visual Studio.

Try to untick "Do not reference...", save your project, close and reload Visual Studio and then try to tick it again. If that doesn't help, delete the project and start a new one.

Tried your suggestions, but still getting the same error: 'This component is already referenced by the build system'.

I have encountered the same error in my work as well. I have the new VS 2010.

Yea, that's what I'm using for the first time. Before now I was using VS 2008.

Ok, you might try to edit the .csproj file of the project. Create a new project, save it, set it to .NET 2.0 and save it again, nothing else. Then close VS and open the project folder and the project's .csproj file with a text editor.

Add to and .

That didn't work either.

The intarwebz have no solution either. If you want, you can upload an affected project (with "Do not reference..." ticked) and I take a look at it.

I compiled with the existing mscorlib.dll ref with no issues... maybe it's a "unissue". Seems whatever ref it has is correct.

Compiling is not the issue. The mscorlib.dll that comes with TS3 doesn't belong to .NET, but to MONO. If you call the wrong code, code the TS3 mscorlib doesn't implement or code that was stripped from it, your assembly won't link and it will be a PITA to debug it.

When trying to compile I got the system.object error. I just redid the script in 2008. Thanks for you help.

There is how to translate into Portuguese of Brazil? I do not understand nor able to do. And I would like to create a mod object with the bear, but his image has changed, and when the sims were with him in the inventory option "try for baby" did not appear.

Whenever I go to open the 'Gameplay' 'Scripts' or 'Gamecore' packages in S3PE I get an error message. I have Ambitions and Late Night, nothing else, and am patched to 6.2.4 (don't know if this makes a difference, but I put it anyway cuz Late Night seems to have created Modding Issues)

By the way, this is the error I get for each one:
Could not open package:

Good tutorial, but I do not understand=(

I was able to figure this one out the hard way. Using VS2008 I created a new project, deleted all references, and set it to .Net 2.0 then saved the solution to the project folder. Closed VS, reopened and then I could import S3 mscorlib.dll. It would appear as though the order of operations is critical.
I haven't tested this on VS2010, but I'm pretty sure it won't work.

So, what is it exactly that you figured out?

Why I was unable to import mscorlib.dll. That seems to be the major problem these users above describe.

I think what this tutorial needs now is a hand-off to the next section, or maybe the interaction API on the wiki to help new users understand the available actions they can do with this code. That's certainly where I am... I can model, animate, and mod, I just need to tie it all together with code.

The problems described above were occurring in VS2010. That's why I went back to '08, because before I didn't have that problem.

The tutorial is linking to VS 2010. Prolly that's why everyone who's trying it is having this issue.

I was unaware that you need to take the steps to set up the project in a certain order. I can't rule out that I always do it in the same order without thinking about it, though. If anyone is positive about this order and knows the order, feel free to alter the related wiki page. It's outdated anyway.

Hmm, that's actually a pretty big step from a beginner's tutorial. I'm not sure how to cover that.

I don't see a way to directly link to VS2008.

I am seeing a difference in the tutorial where we look at "ScrapPaintingInteraction interaction" via Reflector.

The tutorial shows the class as public "public sealed class ScrapPaintingInteraction : ImmediateInteraction<Sim, Easel>". But looking with Reflection or ISpy it shows up as private "private sealed class ScrapPaintingInteraction : ImmediateInteraction<Sim, Easel>"

Is that a change I should be making when copying existing classes? Or did I miss some step?

Thanks,
