XInputDotNet not working when building for UWP in Unity

Question

I am working on a game where a controller has to vibrate. I have found the XInputDotNet plugin which worked very well in the editor and a normal windows build, but if I build for UWP (both Xaml and D3D) the controller doesn't vibrate.

When building in unity for UWP it also gave me an error saying this:

Plugin 'XInputInterface.dll' is used from several locations:
Assets/Plugins/x86/XInputInterface.dll would be copied to
<PluginPath>/XInputInterface.dll
Assets/Plugins/XInputInterface.dll would be copied to
<PluginPath>/XInputInterface.dll
Plugin 'XInputDotNetPure.dll' is used from several locations:
 Assets/Plugins/x86/XInputDotNetPure.dll would be copied to
<PluginPath>/XInputDotNetPure.dll
 Assets/Plugins/x86_64/XInputDotNetPure.dll would be copied to
<PluginPath>/XInputDotNetPure.dll
Please fix plugin settings and try again.

UnityEditor.Modules.DefaultPluginImporterExtension:CheckFileCollisions(String)
UnityEditorInternal.PluginsHelper:CheckFileCollisions(BuildTarget) (at
C:/buildslave/unity/build/Editor/Mono/Plugins/PluginsHelper.cs:25)
UnityEditor.HostView:OnGUI()

The only way I found to remedy this is by deleting one of the plugin folders.

I tried manually copying the ddl's to the build folder, but this didn't help. I tried using the 32 bit dll's and the 64 bit dll's, I tried building for x86 and x64 and I tried all three modes in visual studio(Debug,Master,Release).

I found some links to the Windows.Gaming.Input namespace, but I dont't know if it is possible to add this namespace to unity and if so how.

Does anybody have an idea how to fix my problem?

Answer 1

Libraries for UWP must be compiled separately, they must be assigned to UWP only and configured correctly.

So I have ported XInputDotNet library for UWP apps.

You can download prebuilded binaries from Unity Forum by this link. Also there is an instruction how to use it.

Using ported library you can continue using same code for different platforms.
