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"

[4.7.5] "Get camera location" reports wrong values in VR after rotation

Hi there,

the positional camera tracking reports wrong results after a yaw-based turn.

Simple test:

alt text

This draws a blue circle around your position which should always follow your head movements. Additionally you should see a line pointing from slightly unter your eyes into the direction of view.

Please note: ("Get Camera Location" does not take the HMD into account so I add the vector of "Get Orientation and Position" as local offset)

Everything works as expected until you turn your character to the right. After that, the blue circle will shift to left and right when you move your head forward and back. The line trace also starts from a point next to your head.

This means, that the position of the camera simply cannot not be right.

I currently don't know how to fix this and it completely messes up my view-based selections. :(

Hello btengelh,

I went ahead a double checked on this issue for you. It appears that this is working as intended you will need to update the control rotation, or use bFollowHMDRotation to avoid this issue. I hope that this information helps.

Make it a great day
