RE: [scripting] OM inside SCOP doesnt work but command does?!

In fact, changing the value even using the OM is bad. No changes to anything that isn’t plugged into a port is the rule. Since the mute parameter isn’t animatable you can’t  plug it into a port.

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
