the system may allow you to do this without fialing, but
calling the setvalue command during the evaluation
of an operator is very bad. Not only does it
screwup the undo stack, but it dirties the graph while it's trying to
clean itself.
if you need to animate the mute of your operator, why don't
you just add your own 'mute' parameter to
your SCOP, and implement it
by checking it and skip most of the code in your evaluate? That's all that
the mute is doing.

Subject: [scripting] OM inside SCOP doesnt work but
command does?!
Hi there,
As you cannot link a SCOPs
"mute" parameter or put an _expression_ on it, I made another SCOP that itself
should control the "mute" parameter of the first SCOP. And I was learning my
lessons with SCOPs I tried to use the Object Model rather than using a command
[somewhere in the docs it says: "You must never try and call a command
from inside an operator, unless that command does not affect scene data at
all..."]
So I went with ( I hope this counts as
OM):
Out.Value.Parameters("mute").Value =
InMuting.Value.Parameters("MuteIt").Value
This correctly toggles the the
checkbox for the SCOPs "mute", however it doesnt mute it at all - the yellow
"m" on the SCOP is also missing
On the other hand (if you use the
command - which you are not supposed to do!):
SetValue Out.Value &
".mute", InMuting.Value.Parameters("MuteIt").Value
This does everything
want: checkbock, yellow "m" and correct muting of the SCOP...
Might
be someting stupid from my side, but this doesnt make sense, does it? And if
it does, please let me know...
Thanx in advance
Philipp
