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"

How can i link 3d widget to door rotater?

Hi everyone! I need some help in solving link problem.

TARGET: Player go into Triggerbox ->Button appears(widget in actor placed at world) -> Button pressed-> Door open.

I have:

WidButton - widget ui, 1 button and event 'On click'.

3dWidget - Blueprint with WidButton, Triggerbox and simplest hide/show brunch.

Rotator - BP with rotation script based on timeline.

The problem is that i`ve tryed connect "Rotator" to "WidButton" with dispatcher, with "cast to" and "Macros", but failed.

When I make all of it at Level BP it works, but in game it works nonstable.
