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"

Getting Direction based on Input


I need help with calculating the YAW to rotate my character to based on which keys are currently pressed.


I have a character (Orient rotation to movement) that does a roll animation when pressing Left Shift.

In the code for the LeftShit action Pressed, I need to check which directional keys are pressed at the time of Left Shift being pressed.

I know how to check if a key is pressed, but I don't know what to do after that. How can I get the Yaw that I need to turn my character to before playing the rolling animation?

Here are some screenshots that help to explain what I'm after:




If somethings not clear, I can post a video or something to better try and explain.

You can get the Yaw value like this.

Forward and Right are my axis input names.

Thanks for the reply.

This works as long as the camera is directly behind the character.

If I rotate my camera to in front of the camera, the yaw is the opposite of what it should be so I roll the wrong way.

just add them to the control rotation.

If you're using a custom camera and not one derived from the controller you can replace GetControlRotation with Camera->GetWorldRotation
