Getting an object coordinates

[rubenchov]

Hi all

I am new at Sketchucation, and at programming Ruby too.

I have a SU model, consisting of one big box and a servo. The servo is controlled by a slider (as used in sketchyphysics)

I just want to be able to move the slider and store the position of the box (it can be the center) in a global variable.

That's it

Please help me but please write in the most simple way so I can understand.

Thanks, I really appreciate your help

We stay away from using global variables in a shared objectspace like SketchUp Ruby.

I will assumed the Box is made of grouped primitives:

grp = Sketchup.active_model.entities.grep(Sketchup;;Group).find {|g| g.name="Box" }
if grp
  @pos = grp.transformation.origin
end
