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"

If you execute commands in C++ to do something that means you really doing something wrong, you need to search for proper functions for this. There should be something as console commands have access to exact same APIs as you do, C++ is not blueprint to do console commands.

In UEngine (which oyu access via GEnigne) there XRSystem pointer intefrace for VR/AR systems, from there you can access variority of functions related to HMD.

http://api.unrealengine.com/INT/API/Runtime/Engine/Engine/UEngine/XRSystem/index.html

In there you got GetHMDDevice() and ferther in EnableHMD(bool). Note that moth XRSystem and HMDDevice can be null if those systems are missing, so do check to prevent crash.

You can also look up blueprint node source code of VR to see what to do to do something:
