Rift | A lightweight mod loader and API for Minecraft | Video Game library

I would like to create a graph. To do this, I have created a JSON file. The Skills (java, python, HTML, json) should be the links and the index (KayO, BenBeck) should be the nodes. Also the node must not fall below a certain minimum size and must not become too large.

After that, I would like to be able to call up the list of publications on the right-hand side by clicking on the node. The currently selected node in the visualisation should be highlighted.

I have already implemented from this example (https://bl.ocks.org/heybignick/3faf257bbbbc7743bb72310d03b86ee8). But unfortunately I can't get any further.

The error message I always get is:

Uncaught TypeError: Cannot read property 'json' of undefined

This is what my issue currently looks like:

The JSON file:

I am using npm app-store-scraper package to get the app ids of 1000 of apps from the App Store. Using this npm package I am able to generate a list of JS objects and from each object, my goal is to fetch the "id" field and store it in a .csv file. How can I achieve this?

below is the piece of code I am using.

I recently started playing with Arduinos, and, coming from the Java world, I am struggling to contend with the constraints of microcontroller programming. I am slipping ever closer to the Arduino 2-kilobyte RAM limit.

A puzzle I face constantly is how to make code more reusable and reconfigurable, without increasing its compiled size, especially when it is used in only one particular configuration in a particular build.

For example, a generic driver class for 7-segment number displays will need, at minimum, configuration for the I/O pin number for each LED segment, to make the class usable with different circuits:

I'm trying to print the member's current activity (Game Playing) but when I print after.activity.name it gives me my custom status

Basically I am working on a mixed reality experience using the Hololens2 and Unity, where the player has several physical objects they need to interact with, as well as virtual objects. One of the physical objects is a gun controller that has an IMU to detect acceleration and orientation. My main challenge is this : how do I get the physical object's position in Unity, in order to accurately fire virtual projectiles at a virtual enemy?

My current idea is to have the player position the physical weapon inside a virtual bounding box at the start of the game. I can then track the position of the virtual box through collision with the player's hands when they pick up the physical controller. Does OnCollisionEnter, or a similar method, work with the Players hands? (see attached image)

I am also looking into the use of spatial awareness / image recognition / pose estimation to accomplish this task, as well as researching the use of a tracking base station to determine object position (similar to HTC Vive / Oculus Rift ).

Any suggestions, resources, and assistance is greatly appreciated here. Thank you!

EDIT UPDATE 11/30/2020 : Hernando commented below suggesting QR codes, assume for this project we are not allowed to use QR codes, and we want as as precise orientation data as possible. Thanks Hernando!

I built an application that uses OpenXR with DirectX to display a simple scene in VR. As I'm tasked with implementing this in an already existing project, it's built using CMake, which works perfectly fine with Visual Studio 2019.

The application can run without any issues on the Windows MR Portal, as well as on the Oculus Rift S with the Oculus OpenXR runtime.

Now the next step is to get it running on the hololens. As I need an UWP project to do this, I created a .sln for the application I want to run on the hololens with CMake as follows:

I tried to create horizontal RecyclerView and bottom Navigation Bar I made horizontal_card_item.xml, HorizontalView.kt (class), DataSource.kt , and HorizontalViewAdapter File, for recyclerView.

Here's my code of Main Activity.kt

I want to deserialize a local json file using Gson to create a recyclerview. However I get an IllegalStateException on below line.

TL;DR: For a youtube channel, I am going to try and control an avatar in a similar way to the gif below. Essentially recording my movements in VR and then using them in a video.

At my disposal I have an Oculus Rift S and free time to try things out in unity and other programs.

What I have tried so far:

1. Recording within other games which have built in recording features This does not provide me with the customizeability I need
2. Recording within unity I have not had success implementing recording at all into unity.

There are clearly a variety of ways to solve this, and I have spent a few hours just trying to get a solution, but I cannot find one which works.
