SetCoords Command 

 SetCoords
SetCoords( <Object>, <x>, <y> )
Changes cartesian coordinates of free objects. This command uses values of the coordinates, not their definitions, therefore the object stays free.
Note: This command now works for Sliders, Buttons, Checkboxes, Input Boxes, Images. If “Absolute Screen Position” is selected then xy are in screen pixels.
My template has stuff like this
SetCoords[I1_1,x(%1),y(%1)]”,”SetCoords[I2_1,x(%2),y(%2)]”,”SetCoords[I3_1,x(%3),y(%3)]
and it’s the “on Click” code for the “reset” button.   I assume these are what send the shapes and text boxes back to where they started.
Clueless am I:
  • it says it now works for an assortment of objects, but the object in my example doesn’t happen to be any of them — I’m pretty sure it is a point.  So am I in the wrong place?  Or am I expected to know that it “always” worked for points?
  • What does x(%2) mean?  I’m thinking something that means ‘a point you assign at some point’ —  like “the second choice of points from my list.”

Just keep clicking and guessing!

What would be useful?   Erm, some examples.   Okay, *really* useful would be the different ways you could use it and what they looked like (e.g., my example).   Snork.
