The other day, wanting to give shape to an idea I had, I created something like this ↓. ARKitを使ったリモートタッチパッドの実験。精度がまだ荒いけど基本的には上手くいってる。#ue4 #arkit pic.twitter.com/Kt5E5fPCQn — ayuma (@ayuma_x) December 26, 2019 When you trace your finger over the iPad, a line is drawn on the display inside the iPad, but when you remove the iPad, the same line is drawn on the actual display. This might be confusing at first glance, but actually, nothing is added to the iPad side display. Only the camera feed is shown on the iPad’s display. ...

ObjectDeliverer Version 1.2.1 Released This time, I fixed the following bug pointed out by a user. Editor crashes if a port already in use is specified for UDPReceiver InnerSocket = FUdpSocketBuilder(TEXT("ObjectDeliverer UdpSocket")) .WithReceiveBufferSize(1024 * 1024) .BoundToPort(BoundPort) .Build(); Receiver = new FUdpSocketReceiver(InnerSocket, FTimespan::FromMilliseconds(10), TEXT("UProtocolUdpSocketReceiver")); Receiver->OnDataReceived().BindUObject(this, &UProtocolUdpSocketReceiver::UdpReceivedCallback); Receiver->Start(); if (InnerSocket) { DispatchConnected(this); } The above is the source code before the fix. If a port number already in use was specified for BoundPort, InnerSocket would contain nullptr, causing a crash when FUdpSocketReceiver was subsequently generated. ...

Shared Memory Sample I had previously prepared ObjectDeliverer samples on GitHub, but for shared memory, only the reading side was implemented, and the process wasn’t complete. So, I newly implemented the writing side as well. Here, I will briefly introduce the contents of the sample. Overview In this sample, an image captured by SceneCapture2D is extracted from a TextureRenderTarget, and then displayed on another material via shared memory. First, please open the SharedMemory level. All implementation is within the Box Actor blueprint. Reading Side Implementation Prepare a texture and material to hold the pixel buffer read from shared memory. Generate an instance of ObjectDeliverer for reading shared memory and start the process. The shared memory buffer size is set to the image buffer size (800x450x4 bytes). ...

Release to Marketplace Complete I was able to achieve my recent goal of listing on the UE4 Marketplace. What I released is a Code Plugin called ObjectDeliverer. It’s priced as Free, so anyone can use it. ObjectDeliverer by ayumax in Code Plugins - UE4 Marketplace It’s primarily a library for inter-process communication between UE4 applications and other applications. It might not be a perfect match for those using UE4 for game development, but I think it will resonate with those using it for other purposes and wanting to link with other applications. ...
