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"

Get VR Focus State for Vive

Hi there :D i used "Get VR Focus State" to detect if the player is using the VR-Device or if its still sitting on the desk to play the intro-sequence at the right time... on the rift that works perfectly but on the vive i cant get it to work, is there another trick to archive this for vive? would be great to have one solution for both :/

Vote this question. I also want to know how to disable Oculus' auto not focus the VR when i take off the headset.I found it may cause network bandwidth broken, it became very low when OC as a server(P2P).

You could use a VRNotifications component on a blueprint. These have events you can link to (Headset On/Off) and then do certain things when the headset is put on. So when headset is on with the event, check if you have not already played the sequence and then play it.

We have a more involved solution however in C++, that uses the core delegates for HMD.

 FCoreDelegates::VRHeadsetPutOnHead.AddUObject(this, &SomeClass::HMDPutOnHead);
 FCoreDelegates::VRHeadsetRemovedFromHead.AddUObject(this, &SomeClass::HMDRemovedFromHead);

When these delegates fire the code functions, you can do what you need to in there or create blueprint events to do it in blueprints as well.
