Customizing layer stepping

Customizing layer stepping

Hi,

how can I can change the stepper for PDF-Layers, the code from the presentation
module 60 use InvokeStepper and makes with every step only the next
layer visible
but I want to hide also a few layers in certain steps.

In my example in the steps one to seven the layer for each step should be shown
but in the eight step layer eight should be visible and layer seven should be
deactivated at the same time.

You could also see what I want also in the PDF file but it use fieldstacks and
is very slow for more than 100 fields for each graphic.

\usemodule[pre-60]

\setupinteraction[state=start,click=on]

\def\addstone#1#2#3%
  {\StartLocalStep
   \position(#1,#2){#3}%
   \StopLocalStep
   \ignorespaces}

\starttext

\framed
  [width=3cm,
   height=3cm,
   background=invoke,
   offset=overlay]
  {\setuppositioning[unit=mm,factor=5,xoffset=-2.5cm,yoffset=-2.5cm]
   \startpositioning
   \addstone12X% show layer 1
   \addstone42O% show layer 2
   \addstone23X% show layer 3
   \addstone33O% show layer 4
   \addstone21X% show layer 5
   \addstone31O% show layer 6
   \addstone32X% show layer 7
   \addstone22O% show layer 8, hide layer 7
   \addstone00X% show layer 9
   \stoppositioning}

\stoptext

to finish my
module in LaTeX (just kidding).

you need to write additional javascript code then, or alternatively use 
a whole bunch of layers (just define 50) and use the normal referenceing 
mechanism to turn them on and off (you can change actions, so then a 
click can turn on/off severel of them)
