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 up vector from socket?


I'm trying to get the up vector from a socket. So far I can get the rotation and the location of the socket, but getting the forward and up vectors I can't seem to do, at least with the functions I know of. In Blueprints one just needs to use the Get Forward Vector that takes a rotation and use the Get Socket Rotation function. Is there such a function in C++ or do I have to do some fancy maths?

You can right-click blueprint nodes and choose "Goto Code Definition" and it will lead you to the code definition for the blueprint node. To get the up vector, all you need to do is FRotationMatrix(in_Rotator).GetScaledAxis(EAxis::Z) with in_Rotator being an FRotator that is the socket's rotation.

So not only did you answer my question you taught/reminded me that I can look at code definitions of blueprint nodes. Thank you :)
