thanks.

a few more additions (right-click--> dynamic components -> component options)

• pick the number of boxes (square array)
• how many beers? (straightness of rows and columns waver)

.

1024 boxes, a 12-pack, and change the shape of the box component

I just made this and gave it a twist. Very awesome!

yeah, it's something to do with replacing the box component with one on a different axis.. haven't quite figured out how to control it properly.. i made it this far:

sweet!
(i'm not sure how to use the code but the gif looks cool )

just paste into 'Ruby Console' hit return, will run till end of session...
it's only active when inside the DC so you can do other modelling...

I can put it in a rbz with the DC if you want...

oh nice. i see now.
it works along with the dynamic component i posted.. i didn't realize things like that were possible.

but yeah, that's a lot better than manually triggering the redraw

nor did I...

I improved the script to only do one redraw after the move [was trigging twice]...

there are probably other ways to do this, but it seams to work...

updated working version...

class JcB_MoveToolObserver < Sketchup;;ToolsObserver
    def onToolStateChanged(tools, tool_name, tool_id, tool_state)
      attractor = Sketchup.active_model.selection[0].definition.name == 'attractor'
      moved = tool_state.to_s == '0' && tool_name.to_s == 'MoveTool'
      @count = 0 unless @count == 1
      
      update = attractor && moved
        if update
          selection = Sketchup.active_model.selection[0].parent.instances[0]
          @count = @count + 1
          puts(" first click of " + tool_name.to_s ) if @count == 1
          if @count == 2
            puts(" second click of " + tool_name.to_s )
            $dc_observers.get_latest_class.redraw_with_undo(selection)
            @count = 0
          end
        end
    end
 end

 Sketchup.active_model.tools.add_observer(JcB_MoveToolObserver.new) if not defined? JcB_MoveToolObserver

here's a fun bit of code...
now it does what the OP asked...

 look below...

EDIT: changed back to original as my counter was failing

BETTER CODE BELOW...

the other thing I was wondering if arrow keys can be used to move the dc's 'attractor'

You need a Tool to get the key-presses, then read-update-write the position values depending on which key was pressed, then redraw the DC.

This file was made specifically for Jeff's DC Magnet Beer model.

cheers Jim,
that works and is much cleaner than i was attempting...

what other thing can we do with ruby to manipulate DC's?

I'll see if I can turn this into a pick point version...

Hey, I want in on the fun too.

[driven]

@sam yours looks cooler than my effort...

click anywhere to move 'magnet'...

Next step is multi- attractors

heh.. yeah.. i thought about it but it would be really weird to do in DC..
that kind of math is probably possible in DC but once things start getting complex, it's either hard to keep track of or you end up with really long/weird formulas that are equally hard to keep track of

i guess first you'd have to apply a 'strength' to a single magnet (so far, these aren't really magnets.. the objects just all point at the 'magnet' but the attractor isn't actually pulling on them)

then make two of those magnets and let the strengths fight each other
