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"

Spring Arm Component Rotation Bug

I just update my project to 4.17 and came across a issue, I was using the Spring Arms rotation to get the forward vector to do a line trace, and after updating this trace broke, so i printstringed the rotation of the Sprint Arm and its no longer getting rotaion on its X and Y axis when the pawns camera moves.

Product Version: UE 4.17

Hi OverRated_AU,

I attempted to reproduce this using the 3rd Person Template but the default spring arm print the correct forward vector even after upgrading to 4.17.

Could you provide exact repro steps and/or a small test project that has the issue?

I can provide a test project if you need, you can reproduce this issue but creating a 1st person template, then adding a SpringArm and dragging the FirstPersonCamera onto it so its childed to it, then setting the SpringArm camera settings to use pawn control rotation, then printing the rotation of the spring arm on the event tick, you will see only the Y axis updates, you can test this in 4.16 and it updates fine, i can use the camera rotation but with camera lag enable it gives my placement actor delayed movement thanks.

I was able to reproduce this issue, so I've created JIRA UE-48351. Our developers will be investigating further.
