Showcase how to convert byte array to nativearray<byte> and vice versa ?

hello
I want to send byte array from server to client with unity transport . how do I do this?

Code (CSharp):

1.          NetworkPipeline pipline = ServerCode._UnreliablePipline;
2.             if (ServerCode.m_serverDrive.BeginSend(pipline, clientlistener.m_connections, out var sendData) == 0)
3.             {
4.                 sendData.WriteBytes(bytearray);
5.                 ServerCode.m_serverDrive.EndSend(sendData);
6.  
7.             }

Error :

[I]Argument 1: cannot convert from 'byte[]' to 'Unity.Collections.NativeArray<byte>'[/I]

 

ive used this,
https://forum.unity.com/threads/cop...to-a-byte-array-and-back.549727/#post-3635716

 

I tried it and I faced with this error

Code (CSharp):

1.  
2. NullReferenceException: Object reference not set to an instance of an object
3. Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle.CheckReadAndThrow (Unity.Collections.LowLevel.Unsafe.AtomicSafetyHandle handle) (at <24599fe2776145d58ab771516c063d56>:0)
4. Unity.Collections.NativeList`1[T].get_Length () (at Library/PackageCache/com.unity.collections@0.17.0-preview.18/Unity.Collections/NativeList.cs:223)
5.  

 

I solved my problem with this line code. but i got another error from this line.

Code (CSharp):

1.  
2.  
3. NativeArray<byte> NativebyteArray = new NativeArray<byte>(bytearray, Allocator.Persistent);
4.  
5.  
6.    NetworkPipeline pipline = ServerCode._UnreliablePipline;
7.             if (ServerCode.m_serverDrive.BeginSend(pipline, ServerCode.m_connections[i], out var sendData) == 0)
8.             {
9.                 sendData.WriteBytes(NativebyteArray);
10.                 ServerCode.m_serverDrive.EndSend(sendData);
11.      
12.             }
13.  
14.  

error:

Code (CSharp):

1. A Native Collection has not been disposed, resulting in a memory leak. Allocated from:
2. Unity.Collections.NativeArray`1:.ctor(Byte[], Allocator)

 

After `EndSend` call `Dispose` on the native array. Also you probably want to use `Allocator.Temp` here instead of `Persistent`.

 

So can we call Dispose on array that is allocated with persistent tag ? I don't think so ...

 

Yes, but if I try I got this error all the time :InvalidOperationException: The Unity.Collections.NativeArray`1[System.Byte] has been set to undisposable and cannot be deallocated.

this is how its init : _data = new NativeArray<byte>(_rt.height * _rt.width * 4, Allocator.Persistent);

if i do next OnDestroy()
{
_data.Dispose();
}

I have error saying that this is not possible ,

 

yes I use it with AsyncGPUReadback.RequestIntoNativeArray ,and from it i pass it to a job , so Async feeds data to a array than i pass it to a job to work on it ( encode it to a PNG ) .

 

Yes , GPU readback is holding nativeArray is need with it before I call destroy on object . Now its solved thank you for assistance and help.

 

if (byteArray.Length != 0) byteArray.Dispose();
byteArray = new Unity.Collections.NativeArray<byte>(currentSize, Unity.Collections.Allocator.Persistent);
Hello, I am new to Unity and C#, but I feel I face the same probelm. If my byteAaary is created like this, how can I dispose of it?
