Getting relative angle of two objects

[Mulbin]

I'm having a little trouble getting something to work, I need to turn an object on it's axis to match another (match it orientation, not point towards it)... trouble is I cant use standard look functions as I'm turning it with physics so I need to get an accurate reading on the amount of degrees clockwise or anticlockwise until the objects are aligned.

I have had some success simply comparing the rotation of each object, but the trouble occurs when the two objects fall either side of zero degrees.

Is there a better "get" function than just trying to calculate from world rotations? Ideally I'd like a function that just gets the relative angle of the same axis on each object, with a positive value if the other object's axis is within 180 degrees clockwise and a negative if the axis is within 180 anticlockwise.

This is so I can apply a physics torque to rotate to match the object using the shortest route.

Hi,

 You should try the GetDeltaAngle custom action on the Ecosystem.

It has a "signedAngle" option which could be exactly what you are looking for.

let me know if this doesn't help.

Great, I'll check that out!  Thanks

Hi, I've tried the GetDeltaAngle action but it doesn't have the option for "signedAngle" which you mentioned.

Hi,

 oups sorry, you need "Get signed Angle to Target" actually.



Bye,
