Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Google VR Crash When TextBox Selected


I am currently facing issues while working with Google VR. So I have a setup created where users can select a TextBox and input strings from a keyboard. All of this works when I tested it out on the computer, but when I packaged it and run it on my Pixel XL, it completely crashes whenever I select the TextBox! Other interactions done to the 3D widget such as button clicks and ScrollBox works except for this. Any help is much appreciated!

Hello Scrypter,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?

  3. Could you provide screen shots of any settings/blueprints/widgets that may be involved with this issue?

  4. Does this issue still occur on the device when not using VR?

Hi Rudy,

Answering the questions u asked:

Yes, I created a blank blueprint project with options Mobile/Tablet, Scalable 3D or 2D and No Starter Content

I created a Blueprint Pawn with the following Components and Eventsalt text

Then I created a Widget Blueprint with only a TextBox on it and no events were added alt text

Then I created an Actor Blueprint with a widget component referencing to the Widget Blueprint with no events as well alt text

I placed both the Pawn and the Actor BP to the World and run it.

It works when I run it on the computer, but when I package it, Android (ATC), and have it installed on my phone, Google Pixel XL, for Daydream, it crashes when I clicked on the TextBox.

It would run normally if I just interact with other components of my project and only crashes, stops working and not responding to any inputs, when I clicked the TextBox.

As for any settings on the project itself, I followed the steps on how to develop for Google Daydream based on the documentation as provided:

https://docs.unrealengine.com/latest/INT/Platforms/Android/GettingStarted/index.html https://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/index.html

Any help at all on the issue would be very much appreciated :)
