Question by JHogins · Aug 01, 2014 at 02:25 PM · native plugin

UnitySetGraphics not called in native plugin

I am trying to run the sample native plugin from http://docs.unity3d.com/Manual/NativePluginInterface.html in Windows x86, but Unity is not calling my UnitySetGraphics or UnityRenderEvent functions. I have tried changing the method signature to __UnitySetGraphicsDevice__ and __UnityRenderEvent__ but nothing changed.

I checked whether the functions were called by setting breakpoints in Visual Studio and attaching the debugger to Unity. SetTimeFromUnity is being called every frame.

I am using Visual Studio 2013, building x86.

Here is the dll in Dependancy Walker: alt text

Notice no name mangling.

Edit: Tried Visual Studio 2008 with no success.

I'm having the exact same problem, see my question here: http://answers.unity3d.com/questions/746238/low-level-native-plugins-not-working-in-43-on-wind.html

It magically started working one day, but after making changes to the .dll name it is now broken again. I don't know what (if anything) I did before to get it working.

I've run into this problem twice now and this appears to have been what fixed it for me:

  1. Close Unity

  2. Delete \Library\metadata\

  3. Delete everything in \Assets\Plugins\ and then place your .dll in it

  4. Restart Unity and let it reload the metadata

It magically started working a few days ago, and I assume this is why. Thanks!
