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 the Rotation from any Object results in a wrong pitch value


i have little big issue with the pitch value when i wanna get the rotation of any object, actor, pawn...whatever.

It is really wierd.

Let's make a very simple example:


Make vector node is our forward vector. Image an object and it would be upside down half.

Let's get the rotation! I would assume a value like "Pitch=135". Yaw and Roll are zero. Easy math!

What i get is Pitch=45. Pitch values are between -90 and 90. Always! Whatever rotation i use, whatever object i rotate, whatever workaround i try. I have read all the pitch bug posts and solutions. I know the gimbal lock thing. But even if the axis values are not zero, the pitch value is wrong.

I prefer BP. I would use C++, but the problem is much bigger than i thought. Because it is not the calculation, it is the "get value" at any state. If an object is upside down, i want the right pitch. I cannot rewrite the whole rotation stuff :D

Thanks in advance. If anyone has a slight and right solution, i would appreciate :D How would a new "Get World Rotation" function look like. I could work with that a new get rot function.
