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 PointerIndex for UMG button click

Using BluePrint, I'm trying to figure out which VR motion controller clicked on a UMG Widget button.

The player is facing a wall with a grid of buttons, each corresponding to a sword. The player can aim at the wall with either/both hands and click to equip the selected sword to the hand that clicked the button.

  • The wall is set up as an Actor with a Widget component.

  • The hands are actors that have WidgetInteraction components attached to MotionController components.

  • OnBeginPlay, the WidgetInteractions calculate their PointerIndex based on the handedness of the MotionController component

  • I thought I might be able to use the GetPointerIndex node, but I'm unsure what event I would feed into it.

Thanks in advance!
