    Hi there :) my first question on these forums :D

    enjoying unity so far but i've hit an "is this possible" question.

    I have a c# network library that i've imported into Unity as a DLL. I've got it working when i deploy a standalone client but it doesnt work when i do a web player deployment.

    Is it possible to use additional DLLs for a web player deployment? I have the indie version trial at the moment so is there a chance this is a pro feature or is it just not possible?

    Any help much appreciated :)

    Yes. This should just work.

    You might want to look at /Applications/Utilities/Console.app for output when loading the web player.

    Thanks for the speedy answer Joachim :)

    Looks like its a security exception caused by using the System.Threading classes.

    Code (csharp):
    1.  
    2. unity security internal call - throwing exception
    3.  
    4. DETAILED EXCEPTION
    5.  
    6. System.Security.SecurityException: This method is not supported in the unity web player for security reasons.

    It is because security reason. Yes, u can deploy it but u need to register the dll manually or by installer on client pc. Just like unity web player. :)

    Maybe I didn´t undestand well but I get from this that if I have a project with javascript and c#, I wil have problems with the c# part of the code when using Unity Web Player. Is this correct?.

    Actually when you use a .NET assembly DLL like he is doing, the code is added to the assembly for the whole game, so no DLLs to register. That's why we can still use them with the webplayer and Unity Indie, where we cannot use standard DLLs. Unless I am mistaken. ;-)

    He could use some library which need proper authorization for example network library. I have developed a activeX like on c# .net, it run fine on browser but can't execute network library or read/write to disk. It's because security, client application can't simply access those features. But I'm not sure with dll which load with unity web player.
