Dear members,

Right, it is just a quick hack.
To keep track of the activation and deactivation of the objects you just have
to add two Links and another row of ActionSlots. Here is the new solution:

{:Bitmap
1
...
}

{:Audio
2
...
}

{:Bitmap // Dummy for TokenGroup
3
...
}

{:Bitmap // Bitmap to run
4
...
}

{:Link
100
:EventSource 1
:EventType IsRunning
:LinkEffect (
:CallActionSlot (500 1)
:CallActionSlot (500 2)
)
}

{:Link
101
:EventSource 2
:EventType IsRunning
:LinkEffect (
:CallActionSlot (500 1 )
:CallActionSlot (500 2 )
)
}

{:Link
102
:EventSource 1
:EventType IsStopped
:LinkEffect (
:CallActionSlot (500 2)
)
}

{:Link
103
:EventSource 2
:EventType IsStopped
:LinkEffect (
:CallActionSlot (500 2 )
)
}

{:TokenGroup
500
:MovementTable (
( 1 2 3 )
( 1 2 3 )
)
:TokenGroupItems (
( 3
:ActionSlots (
( :MoveTo ( 500 2 ) )
( NULL )
( NULL )
)
)
( 3
:ActionSlots (
( :MoveTo ( 500 3 ) )
( :MoveTo ( 500 1 ) )
( NULL )
)
)
( 3
:ActionSlots (
( NULL )
( :MoveTo ( 500 2 ) )
( :Run ( 4 ) )
)
)
)
}

I think the TokenGroup solution has the advantage that you can easily add
new dependencies without adding a lot of objects.

Regards,

Andreas
