I want to set the SpringArm’s transform.
only the rotationY value is correct, other values are confused. lotationY -3.56 set to locationX. why?
By default, the rotation of a spring arm is relative
You could use ‘set relative rotation’?
I have tryed SetRelativeLocationAndRotation node, but it does’t work 
check teleport, maybe there is something in the middle that blocks it to reach the location
I took the standard third person, and put this in to increase the height on the swing arm
It works fine 
I try again. SetRelativeLocationAndRotation can work. but in another project, SetWorldLocationAndRotation can work. the difference butween them is BP_character root transform.
Yes, you can do exactly the same thing, but using GetRelativeLocation and adding to it, and then calling SetRelativeLocation.
Did you develop that whole interface I see there? If it’s a product, there may be other code holding the spring arm in place…
