I need a function to keep an object always facing up on the Z axis, so that when the component is rotated on the X and Y axis, this object, inside the component, remains in the same position.
this code is in Roty of object:
Roty=IF(OR(DC!roty>0,DC!roty<0))-DC!roty
Why not just negate the parent’s rotation ?
rotx: =parent!rotx*-1
roty: =parent!roty*-1
this doesn’t work, any correction that works by correcting the rotation of the Y axis while the DC is in the home position works, but when I rotate the DC on the Z axis and try to rotate the Y axis (which is now facing the X) everything stops work.
I will make a more detailed video
this is the file i’m working on

The rotational interaction between the native code and the DC is not intuitive. The various rotations can all change when one value is changed. A complication of pitch, roll, and yaw

However I know you can isolate the effects by adding an extra nesting and not reference the parents rotations
I suggest, rather than trying to auto this, that you create the DC to react to a option or onclick
The attached file has a basic DC, that change to onclick, all with same uniqueness change.

now I understand the complexity of the thing kkk I was inspired by the tip to solve the issue, thank you all for your help.
I’ll leave a video showing how it turned out
