I've created an animation that requires the Z Axis location of one object (Empty) to control the scale of another (Circle). I can't seem to get the Transform Constraint to work for this - if anyone can advise on a simple way to do this or point me in the direction of a detailed explanation of the Transform Constraint I'd be grateful.

$\begingroup$ why don't you just use a simple driver? if you wanna have a detailed explanation of transform constraint, i would search on yt for a tutorial.... $\endgroup$– ChrisCommented Nov 18, 2022 at 9:02

As Chris says you could use drivers.
For a Transformation constraint, here are the settings you need: Select the Target object, enable Extrapolate, Map From > Location with Z Min > -10, Z Max > +10 (or whatever values), Map To > Scale, XYZ Source Axis > Z and Min > 0.5 and Max > 1.5 (or whatever values):
Here is what it gives:

$\begingroup$ Thank you so much for this, I was finding it quite difficult to gauge the settings, you've been a great help (and saved me a huge amount of hassle), cheers:-) $\endgroup$– K.CeeCommented Nov 18, 2022 at 13:57
