DLL in plugin folder not loaded?
Hallo
I have a running project under .NET3.5 and VisualStudio 2015.
It uses an external dll "OSIsoft.AFSDK". Everting is fine, no issues.
THEN
I moved all dll's (I copied the files one by one from references) to the plugin folder of the Unity project and got the error below.
WHAT I tried
1. Changing plattform setting in Unity of all dll's set to x86_64 and back to "Any CPU"/"Windows"
2. Inspected the dll's with ildasm for the right version and existence of the methods.
Result -> All Methods/Functions are existing.
3. Several restarts of Unity and Windows
4. Checked all solution found with google
5. Removed the System.*.dll's (The error is the same in this case!)
WHAT I don't understand
1. What is the difference between VisualStudio and Unity? Why do they handle the dll's different?
2. When I change the System.Core.dll setting to x86 / Windows it should not be loaded. When I revert the setting it should load it. Whats wrong here?
3. Where can I reliable see what dll's are loaded and where from?
4. Why is the System.Core.dll not loaded when I put it into the Plugin folder?
Target is just Windows / x86_64

how to create a wrapper for C++ class libraries
i want to use some C++ libraries in unity. unity just can use C style function libraries. how should i wrap the classes? think i want to use physx cloth or any other library. unity already do that with physx and some other libraries so it's possible. i know that C++/CLI is not an option here because they are mixed assemblies and mono doesn't support them. my target is windows. some of game libraries are static .lib files and some of them are DLLs. most of the third party game related libraries are C++ class libraries so we all need this. i know about some tools to create wrappers but i want to do that myself programmaticly because tools don't work well always.

How should I add references to additional Mono assemblies?
Unity is built on Mono. Mono includes a large and growing subset of .NET. Much of this subset is available out of the box with Unity, so I can do things like add "using System.Collections.Generic;" to my C# script and start using dictionaries and such.
However, if I add "using System.Data;" (for example) to my script, I get ...
error CS0234: The type or namespace name 'Data' does not exist in the namespace 'System'. Are you missing an assembly reference?
The same thing happens with many other common assemblies. Obviously Unity is giving me a useful set of assemblies, but not everything.
Looking in my Unity 3.1 installation folder, I can see all these DLL's sitting in Data\Mono\lib\mono\2.0, including System.Data.Dll.
I can get my compile error to go away by copying the DLL I want into my Assets\Plugins folder. Is this the correct and best way to add an additional reference? I would prefer something like Visual Studio's reference management -- does this exist with Unity? What if I'm going to build for different platforms, do I need different versions of the DLL's?
This seems like it would be a common question, but searching the docs, answers and forums hasn't turned up a definitive answer. Links appreciated if I overlooked something.

How do I call an Office function from a C# script?
I'm working on a game that needs to use some Excel functions. I tried to import those dll's into the asset folder:
Microsoft.Office.Interop.Excel.dll
Microsoft.Vbe.Interop.dll
Microsoft.Vbe.Interop.Formsl.dll
Office.dll
I'm using code like this:
double[] num;
Microsoft.Office.Interop.Excel.Application oXL = new Microsoft.Office.Interop.Excel.Application();
double resultNum = oXL.WorksheetFunction.Average(num);
It works when I put it into a Windows console application.
I have no errors or warnings while compiling. However, the Unity crashes while it reaches this line of code:
double resultNum = oXL.WorksheetFunction.Average(num);
The error reports "Read from location 00000000 caused an access violation." It seems that Unity couldn't find the WorksheetFunction class...
Does anybody know how to call external functions from unity?
Thanks!

Performance penalties
Are there any performance penalties in putting classes in an external dll rather than defining them directly in Unity and letting them inherit from MonoBeaviour?
Another way to put it - do I gain any performance by defining a class directly in a Unity script, letting it inherit from MonoBehaviour and make it a component of a GameObject, rather than having that class in an external dll and letting the calling script update the external class? This is mainly concerning physics functions in the FixedUpdate().

Build argument -reference:ALIAS=DLL
My problem is the following. As I need to use **System.Windows.Form** namespace for Windows dialogs I first tried to use normal "Edit Reference" in MonoDevelop, search for the .dll in ...\Unity\Editor\Data\Mono\lib\2.0 and just adding it. This caused a problem because as I had algo as reference System, when I write using **System.Windows.Form** and then build the solution, it tells me that it didn't found 'Windows' in 'System' namespace. This is obvious because it didn't had to lookup there. So I solved it in mono by adding "/reference:WinForm=" in compiler additional arguments and in my class heading:
extern alias WinForm.
When I needed to use a namespace from that import I write for example:
WinForm::System.Windows.Forms.SaveFileDialog saveDialog = new WinForm::System.Windows.Forms.SaveFileDialog();
saveDialog.FileName = Path.GetFileName(myPathVar);
My problem now is that I can't access the compiler arguments in Unity. Error: *Assets/scripts/GenerateFiles.cs(1,14): error CS0430: The extern alias `WinForm' was not specified in -reference option*, where do I put -reference??
I have tried:
Unity.exe -batchmode -buildWindowsPlayer "PATH.TO.EXE.exe" -reference:WinForm="C:\Program Files (x86)\Unity\Editor\Data\Mono\lib
\mono\2.0\System.Windows.Forms.dll" but it ain't working =S.
Thanks in advance.

Editor scripts into external assemblies? how?
I have a class that I'd like to have a custom editor for. I have the class working in an assembly DLL ok. Now, how would I go about doing the custom editor? Can I put it into the same assembly? As I get it, it needs to go into (an) Editor folder, so do I have to have two assemblies, one for the main class, one for the editor? Or maybe there's some structure to the assembly itself? So confused!

Can I use .NET 4.5 assembly as external library?

Question about external DLL
Hi Everyone! I Have a problem with an external DLL.
I have to use a C++ dll that i've made to send commands to an eyetracker.
The problem is that in the Unity Editor works, but compilled not.
My C code goes like these:
extern "C"
{
...
__declspec(dllexport) int close_connection()
{...}
}
and in the C# scritpt i use [DllImport("EyelinkConnector")].
I've to put the dll in the "Editor" folder, because if not, it not work. From the unity editor works like a charm but when i compile the program ti can't load the dll, i got an exception that it could not be found. I've tried putting it in the same folder than the .exe, in "system", "system32" and so on, but nothing.
Anyone can help me?

Control output of visual studio 2013 output
I have created an external library with some classes, basically my own game framework for use across many Unity projects. I have the build output going to a Libs folder inside the Assets folder in a Unity project. I went into the advanced build settings and turned the debug output off so it wouldn't output the debug database into the Libs folder. But it puts copies of the dependency .dlls. In this case its the UnityEditor and UnityEngine .dlls. Unity then throws an error, so I have to manually delete those two dlls from the Libs folder. I cannot find a way inside visual studio to stop it from writing those two dlls to the Libs folder. Does anyone know how to do this?
Thanks in advance!

Unity TestTools and External DLL conflict?
Greetings everyone.
I have a problem that I find weird. I have created some dll files that I want to use in my Unity project. I have compiled them with VS2012 and tested them outside of Unity and everything seems good.
I have also Imported them successfully in Unity projects for test and again everything worked fine...until.. I tried to import Unity Test Tools in that project.
Now I have tried this and it seems that, when the projects has Unity Test Tools loaded, my external Dll cannot be loaded and this error message comes up:
> *Internal compiler error. See the console log for more information. output was:
Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.*
*at (wrapper managed-to-native) System.Reflection.Assembly:GetTypes (bool)*
*at System.Reflection.Assembly.GetTypes () [0x00000] in :0*
If I remove the dll, the error stops. If I remove Unity Test Tools the error also stops.
Unity version is 4.3.3f1
Any Ideas?
Thank you very much in advance for any help.

How Is 'fileID' Generated For Classes Inside an External DLL?
When you link to a MonoBehaviour that is inside of an external DLL, the resulting asset file refers to that particular class by a 'fileID' and the 'guid' of the external DLL. For example, a MonoBehaviour named 'a' inside of an external DLL would be show up in an asset's YAML file as:> m_Script: {fileID: -1880535464, guid:> 50df42a15edf64f1caa6bfd8fd2576ef,> type: 3}
Where the guid (50df42a15edf64f1caa6bfd8fd2576ef) is the GUID assigned by Unity to the external DLL file. The 'fileID', however, is constant and is based on both the class's namespace and name. However, I cannot figure out how Unity takes the namespace and class name and generates the 'fileID' field. In our project, we have moved several classes into external DLLs, which unfortunately breaks the links in all of our asset files. If we could generate that 'fileID' field, we could easily repair those broken links inside of our asset files. Could you please tell us how to generate the 'fileID' for a particular class? Thanks.

Using GDAL from Unity
Hello,
I want to read a raster map from my Unity application. I planned to use Geospatial Data Abstraction Library(GDAL) for this task. This is a C++ library but it has a C# wrapper which handles C++ calls. I tried to use its C# wrapper from the unity. However, I could not achieve. Finally, I got the error below:
**Failed to load 'Assets/GDAL/gdal_wrap.dll' with error '%1 is not a valid Win32 application.
', GetDllDirectory returned ''. If GetDllDirectory returned non empty path, check that you're using SetDirectoryDll correctly.
GameController:Start() (at Assets/Scripts/GameController.cs:58)
GameController:Start() (at Assets/Scripts/GameController.cs:15)**
Is there anyone who achieved to use GDAL from Unity?
Or, is there anyone who read raster map from Unity application? If yes, how?
I am waiting for help.
