Vector3 angles and calculations

Unity Engine
1

I’ve learned a bit about the way Vector3 functions work, but I’m still pretty hazy on it. I’m trying to figure out how to do a couple of things:

  • I want to take a Vector3 and rotate it by an angle. So for example, if I were to put in (0,0,1) and I wanted to find a Vector3 that’s 90 degrees from it (around the Y axis), it would become (1,0,0). I feel like there should be a quick way to calculate what the new Vector3 is, but I just don’t know how to do it.
  • I want to calculate the angle between one Vector3 and another. So for example, if the function were given (0,0,1) and (1,0,0), it would return 90.

Any help would be appreciated!

Ah, I knew there had to be an easy one for the second one.

The first one seems to have Quaternions as its input and output, though, not Vector3’s?
