[SOLVED][CLOSED]About importing dll's

Hello,
I'm working on an application (not a game) using Unity.
I've tried to import the follow library https://netdxf.codeplex.com/ but I keep getting the error:

"Error 2 The type or namespace name 'netDxf' could not be found (are you missing a using directive or an assembly reference?"

Unity documentation says that in order to use a library, you just have to drop it in your Assets folder and all the references are created automatically, so I don't know what is going on.

Any ideas?

 

Try put them in a folder called Plugins in the assets folder

 

Did that inside and outside of Plugins, right bellow Assets, and in some other structure

 

Yeah normally you need to make a folder called, "Plugins" inside the Assets folder, and add any managed or unmanaged plugins in there. I notice you're using visual studio. When you add a dll into the plugins folder, it should automatically import into your visual studio project. So it's worth looking up your Reference in the Solution Explorer to make sure it's being imported by Unity.

 

Yes, the reference its there on VS but it still doesn't work.
It's all very strange :S

 

Oh I just checked the download it's actually pretty simple. For some dll's they require the .pdb file as well for reference in Unity. Go to he .zip file again and drag both "netDxf.dll" and "netDxf.pdb" into the Plugins folder. I've tested this on my project and it works.

 

I guess it kind of worked.
But now I'm getting the error: "'Vector3' is an ambiguous reference between 'UnityEngine.Vector3' and 'netDxf.Vector3'"

I'm assuming the DLL has a class called Vector3 and is creating conflicts with Unity's.
Any idea on how to solve this?

 

Well you'll just need to explicitly state which Vector3 you're after. So when you want a Unity Vector3, you'll say "UnityEngine.Vector3", and when you declare a netDxf Vector3 you'll need to explicitly call "netDxf.Vector3'". Like so:

Code (CSharp):

1.     private netDxf.Vector3 someDxfVector;
2.     private UnityEngine.Vector3 someUnityVector;

You can do things like give each namespace an alias to make it a bit quicker:

Code (CSharp):

1. using net = netDxf;
2. using unity = UnityEngine;

Then you can just do net.Vector3, and unity.Vector3.. But that's about as quick as you can make it with this.

 

Alright! I guess I can mark this thread as answered.
I just hope this library has what I need.

Thanks for the help Nigey
