Hi,
I cannot seem to have c# executed AFTER the nativeplugin execution.
I have following pseudo code:
void update()
{
cam.targetTexture = myRenderTexture;
cam.render();
cam.targetTexture = null;
}
void OnPostRender()
{
GL.IssuePluginEvent(GetFunc(), 1 );
// do some stuff AFTER native plugin execution
MyMethod();
}
The code inside MyMethod() seems to get data affected on the native plugin only for the NEXT frame, which make me believe the native plugin is executed AFTER the execution of the OnPostRender() function is complete.
My Question:
Is there any way I can fence / wait or force the unity to execute it and only AFTER continue the call to the MyMethod() ??
I've tried with no luck:
1. GL.Flush() inside OnPostRender after the GL.Issue.
2. Put the GL.IssuepLuginEvent code line inisde the Update().
Would appreciate any help on matter.
regards,
Idan

Custom swift framework in Unity iOS game
I have created a swift framework and implemented it into my Unity project in the same way as it is done in the following tutorials:
https://medium.com/@kevinhuyskens/implementing-swift-in-unity-53e0b668f895
https://medium.com/@SoCohesive/unity-how-to-build-a-bridge-ios-to-unity-with-swift-f23653f6261
The project builds and runs perfectly on my iPhone. However, I get the following errors when uploading to the App Store:
This bundle is invalid - The Info.plist file for /Payload/MyApp.app/Data/Raw/SwiftPlugin.framework is missing or could not be read.
Invalid Bundle - The bundle at '/Payload/MyApp.app/Data/Raw/SwiftPlugin.framework' does not contain a bundle executable.
The swift framework was placed in the "StreamingAssets" folder in Unity, so that it is copied through to the Xcode project. I also used the same post processing script as seen in the first tutorial. The swift framework is in a folder called "Raw" in the Xcode project, if I try moving it to the frameworks folder I get the error "Linker command failed with exit code(use -v to see invocation)" when building the application.
Any help would be much appreciated

Cannot call a native Android method in the latest versions of Unity...?
Hi! The following code used to work in Unity versions 2018.x.x but it seems like the AndroidJavaObject::Call method doesn't work anymore in 2019.1.0? When attempting to build for Android, the line gives an error which states that Call returns void... Am I wrong in assuming it should return an AndroidJavaObject[] here?
using(AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer")){
using(AndroidJavaObject context = unityPlayer.GetStatic("currentActivity")){
AndroidJavaObject[] externalFilesDirs = context.Call("getExternalFilesDirs", null);
//...
}
}
The error:
error CS0029: Cannot implicitly convert type 'void' to 'UnityEngine.AndroidJavaObject[]'
Thanks! :)

Using Native C++ dll in Unity
Hi, I am new to Unity and C++ and C#. I have a UWP component (C++) I want to use in my Unity project through C# scripts. I am thinking the best way to do this is by taking the UWP component and building a dll from Visual Studio. To practice I wrote and generated a managed DLL following a tutorial and imported and used it in Unity. However, the code I want to access produced a native dll and I am unsure how to use that in Unity. So either how do I convert a native dll to a managed dll, or how do I use a native dll in Unity?
Thanks.

Native Android plugin CPU subfolder approach not working
I wrote a native Android plugin for a Unity project. If I place the ARM version plugin into the Assets/Plugin/Android folder and build for an Android device, it all goes well and the app is running fine.
However, if I try to use the CPU subfolder approach, putting different CPU versions of the plugin into the respective Assets/Plugin/Android/x86 and Assets/Plugin/Android/armeabi-v7a subfolders as outlined in the manual (https://docs.unity3d.com/Manual/PluginInspector.html), the app is no longer working and the LogCat output tells me that the DLL was not found.
I even tried to set my "Run device" in the Build Settings to the actual device because I thought that perhaps, launching it from my desktop may cause it to embed the wrong version, but that didn't help either.
Is there an additional step I need to go through so that Unity will embed the correct CPU plugin version in the final build?
Thanks for any suggestions.

Invoking Windows Multimedia timer results to hang
I am on Windows 10, Unity Editor 2018.3.12f1
I have a requirement for very fast (500 Hz) and precise updates, "independent" from the Unity main thread. I am targeting windows desktop only, so the [Multimedia Timers][1] seemed as a good (the only?) fit. However I witness some weird crashes.
When in Editor, when I press the play button, my sample game seems to be working correctly (ie prints in the Debug console, and with great precision when I used stopwatch to measure), but when i stop the game **and** try to run it again, the Editor hangs.
When i build and play, again everything seems normal (no debug messages there of course), but when i attempt to close the program via the 'X' button it hangs again.
I tried [this][2] library which also includes a working example, and I also created this very simple mono behaviour to test it but with same results:
using UnityEngine;
using System.Threading;
using System.Runtime.InteropServices;
using System;
public class MultimediaTimer : MonoBehaviour
{
private UInt32 userCtx = 0;
void Start()
{
// Run();
Thread r = new Thread(() => Run());
r.Start();
}
void Run()
{
MultimediaTimerCallback Callback = new MultimediaTimerCallback(TimerCallbackMethod);
uint timerId = TimeSetEvent(100, 5, Callback, ref userCtx, 1);
Thread.Sleep(1000);
TimeKillEvent(timerId);
}
private static void TimerCallbackMethod(uint id, uint msg, ref uint userCtx, uint rsv1, uint rsv2)
{
Debug.Log("Hi");
}
private delegate void MultimediaTimerCallback(UInt32 id, UInt32 msg, ref UInt32 userCtx, UInt32 rsv1, UInt32 rsv2);
[DllImport("winmm.dll", EntryPoint = "timeSetEvent")]
private static extern UInt32 TimeSetEvent(UInt32 msDelay, UInt32 msResolution, MultimediaTimerCallback callback, ref UInt32 userCtx, UInt32 eventType);
[DllImport("winmm.dll", EntryPoint = "timeKillEvent")]
private static extern UInt32 TimeKillEvent(UInt32 uTimerId);
}
My question is very simple. Is it possible to reliably call the multimedia timer from a Unity program? And if not could someone explain this behaviour I observe? I could encapsulate my timer logic in a separate process and use some form of IPC to achieve my requirement, but I would prefer for convenience to stay withing Unity.
(Of course if you know any alternatives, by all means do say them)

How to enable more than 2 output channels in a native audio spatializer plugin?
We are currently developing a spatializer plugin based on the native audio sdk on Ubuntu 18.04.
---
The **goal** is to use the provided input buffer and 3D position of a mono audio source to compute the **output buffers for 8 speakers** that are placed in each corner of a room (4 at the bottom and 4 at the ceiling). The problem is that **unity provides only 2 output channels** no matter what setting is chosen in the audio preferences. If we choose mono, we get 1 channel, everything else results in 2 channels, even the 7.1 surround option.
---
**How can we enable more than 2 `outchannels` in the `ProcessCallback()` function?**
---
*We are using Unity 2019.2.0f1 on Ubuntu 18.04 but also experienced the same issue with earlier Linux builds. Unfortunately, we are not able to test the code on a Windows machine due to our hardware setup and can therefore not provide any comparison regarding platform specificity.*

Creating a native UAV into a meshes native vertex buffer (DX11)
I have a native plugin which generates mesh data using compute shaders. My ideal solution would be to pass down the native vertex buffer pointer down to the plugin, create a UAV into it, and bind that directly to my compute shader.
Attempting to create the UAV returns an invalid args result. The vertex buffer appears to not be a structured buffer (buffer description has a structured byte stride of 0). Could this be why this method will not work?

GetNativeTexturePtr is not working in iOS plugin
I'm working on creating iOS plugin for saving screenshot. I'm trying to use GetNativeTexturePtr. But it didn't work. It will be NULL in the iOS plugin. I want to know how to use GetNativeTexturePtr.
Please see my code below.
// C# side
System.IntPtr ptr = _buffer.GetNativeTexturePtr(); // _buffer is RenderTexture
_SaveTextureImpl(ptr);
// Define like below.
[DllImport("__Internal")]
static private extern void _SaveTextureImpl(System.IntPtr texture);
Maybe you think that `_buffer` is wrong, but I visualized it on uGUI's RawImage then it worked.
Move onto Objective-C side.
// Objective-C side.
extern "C" void _SaveTextureImpl(id texture)
{
[NativeTextureSaver saveTexture:texture];
}
My understanding is, `GetNativeTexturePtr` will return the pointer of `id` on iOS. So I guess that we can use the pointer as `id`, but it was NULL in the plugin.
Is it my mistake? or Do I need to set up something other?

Native plugin stops working properly after re-opening project
Hi there, hope someone can help.
I'm experiencing weird behavior from native effect plugin granulator added to audio mixer group: if I close the Unity project and reopen it, the signal doesn't pass through the plugin anymore, and the only way to have the signal back is to delete and re-add the plugin from scratch (and re-tweak it). If I bypass the plugin, the dry signal path is just fine.
Any idea what's happening there? Thanks in advance!
I know just very little C# for now, and plugins SDK is still too complex for me to understand.

How to destroy Scriptable Objects on Reimport
Hi,
I have a native plugin in c++ that creates and manages some allocated user data.
A reference to this data created is held by an scriptable object (which is supposed to be shared among several components)
I am taking care of the memory management OnAwake/OnEnable and OnDestroy/OnDisable.
An instance of the scriptable object is created when I import some custom asset format.
Everything works fine, until when I need to reimport this asset.
Basically, I create a new instance of the object in the body of the importer, and (I suppose) Unity internally replaces the old reference with the new one.
The problem is when this done, the OnDestroy (or OnDisable) is never getting called again, so my user data is never destroyed and it causes a small memory leak (it happens only on the editor, and when I reimport the asset, so it is not so critical)
as a workaround, I am keeping a static dictionary that holds the asset file name as key, and the scriptable object reference as value. When I detect that a reimported asset, I directly call the destructor of the user data.
besides being cumbersome, when the importer script itself is reloaded, the static data is cleared, so I still have this corner case memory leak.
ideally, i wanted to rely on the OnDestroy only, so how should I properly reimport the asset so that the SO gets destroyed?
