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"

strange result of add actor rotation

I print actor's rotation before and after add actor local rotation and the delta rotation I added. I got a wrong number on pitch. I added 0 on pitch. But it always change a little bit on pitch. How to fix it? alt text

Try removing the connection from pitch in make rotator and see if you still get those results. If you don't, it's either pitch speed or whatever pitch speed multiplies with.

pitch is always 0. I have printed the delta rotation in middle of the rotation before and after add rotation. P=0.000000 Y=-179.908783 R=0.002523 the rotation before add actor local location P=0.000000 Y=0.190325 R=0.007987 the delta rotation P=-0.000007 Y=-179.718460 R=0.010510 the rotation after add actor local location you can see there is a strange result on pitch.

Well if you are not willing to try and see if it stays 0 after removing connections to the pitch, then I can't help you.

I think this might actually be a bug - if nothing is connected into Pitch, then the value shouldn't change. The values you have posted also seem to be big to be inaccuracies for 32-bit float. I would change the section for this to the Bug Reports section.
