Your advice worked! Had to move a lot of code out of the core Unity project into a shared dll, and that did the trick. One annoying problem now is since I'm using Visual Studio / MSBuild to build my shared dll, I am losing line numbers in my stack traces when there is an exception in the shared dll. Has anyone figured out a way around this? Does the shared dll have to be built with the same version of mono that unity runs in order to get line numbers? Just wanted to update you.

That does kind of limit the idea of the assembly being perfectly external. Why not in stead define some shared abstract classes or similar and via those register from the Unity project with the assembly when its loaded.

I got an external dll loading and running just fine. I had trouble with one thing -- hoping to get some advice on how to do this. I am building my external dll in visual studio. I want this external dll (call it minigame.dll) to reference classes in my main unity project (Assets/Code/). In visual studio I set up the scripts in Assets/Code to build to a dll, gameloader.dll, and made the minigame project reference that. This all compiles fine and dandy. The problem is when I load the minigame assembly at runtime, it cannot find gameloader.dll, because Unity knows nothing about it. Unity has built the scripts into it's own Assembly-Csharp.dll. I also tried making my minigame project reference Assembly-Csharp.dll. That gave me a similar error when loading the minigame.dll at runtime, about not being able to find the Assembly-Csharp.dll (but it had some obfuscated name for the dll). Any ideas of how I can accomplish this? Great article AngryAnt. I got an external dll loading and running just fine. I had trouble with one thing — hoping to get some advice on how to do this.

Though the only risk you would be running is someone changing the behaviour of your webplayer - which has consequences if you have server structure blindly trusting it. Neither client nor server machine can be compromised this way, as the executed code is still sandboxed by the mono runtime. @bill

Of what you mentioned, only reflection is really .net specific. I just went to msdn and started reading up on the classes in the System.Reflection namespace. Regarding design patterns, I would recommend you get a good book on that - always handy to have around.

Sweet! Would you object if I read through the Path and Behave code to get a better idea of how you did it? I'm not sure how that would fit under your licence agreement, but I have no intention of copying your code - I'll write it myself from scratch after having a look at what you've done. The modules I'm writing will be used in a commercial project if management agrees to it, but I'm hoping to get permission to release them as open source back to the Unity community if they look if they could be used outside of our project. Thank you for all of the invaluable assistance. :-) Oh. Wow. Sweet! Would you object if I read through the Path and Behave code to get a better idea of how you did it?
