GetDirty requires a flag as the parameter: op.GetDirty(c4d.DIRTYFLAGS_DATA)
Any gizmo on your tag that the user changes will make the dirty value change.
So it's probably better to poll the slider's value instead of polling the dirty value.
That way you only poll the value for that specific gizmo.-ScottA

While polling the slider's value with a class member variable should work fine.
I just remembered another way I delt with this kind of thing a long time ago in one of my C++ plugins.This will grab the gizmo's data from the tag while the LMB is being held down.
The "break" will stop it from running when the LMB is not being pressed.def Message(self, op, type, data) : doc = op.GetDocument() msg = c4d.BaseContainer() while c4d.gui.GetInputState(c4d.BFM_INPUT_MOUSE, c4d.BFM_INPUT_MOUSELEFT, msg) : if msg[c4d.BFM_INPUT_VALUE] == 0: break if msg[c4d.BFM_INPUT_VALUE] == 1: #This value can be sent to a class member variable for usage in the other overriden plugin methods print op[c4d.MY_SLIDER] breakProbably overkill for your needs. But I thought I'd mention it.

I follow you on the GetDirty method, however, I'm not having much luck getting it to work..
I added the op.GetDirty(c4d.DIRTYFLAGS_DATA) to the Message function.
How to I make it only poll a slider and not the entire plugin?
If you could post a sample code of getting a sliders value change, that would be perfect. And thats for the LMB trick, that will come in handy in the future.
Thanks again,

Even if that works, I don't think it will achieve what I'm after. I have it working in a script. Can I email you that and see if you can translate it to a tag plugin?
I don't know if it's possible in the way I need it to work.
Thanks

You can't. At least I don't know any way to do that.
Dirty can only test if "any" of the object's tag was changed in some manner. It can't tell which specific gizmo was changed.Grabbing the slider's value and comparing it to a class member variable to see if they are the same is the most common way to tell if a specific gimzo was changed.

Hi,
in my Tag plugin I solved it like this:
def Init(self, node) : tag = node data = tag.GetDataInstance() data.SetReal(10007, 0.5) #the slider id and the initial value self.a = data.GetReal(10007) #you can set it to your initial value, too like self.a = 0.5 def Message(self, node, type, data) : tag = node instance = tag.GetDataInstance() if (type == c4d.MSG_DESCRIPTION_CHECKUPDATE) : if self.a != instance.GetReal(10007) : print "slider has changed" self.a = instance.GetReal(10007) print self.aOr have a look to this post

Hi,
did it work for you?
Found out that the succestion from Niklas:
MSG_DESCRIPTION_POSTSETPARAMETER
is the fastest way to solve it.(it´s lighter no additional check for doc or draw like in checkupdate)
But it seems thatc4d.DescriptionPostSetValue() (this should give you the desc id of the changed parameter)
is not defined in Python and therefore you have to set a variable
and compare for changes like in the script I´ve posted before.Cheers,

Hi. Unfortunately I realized that it is not possible what I want to do. Take that script i posted and run it in script manager. A master slider will change the values of "child" sliders. But that will still be recognized by the MSG_DESCRIPTION_POSTSETPARAMETER.
I don't think its possible. Thanks though.

Hi,
it is possible.
What you need is some more if clauses, to decide if the masterslider controll the values or an individual sliders does it, like:def Init(self, node) : tag = node data = tag.GetDataInstance() data.SetReal(10200, 1)#the masterslider data.SetReal(10201, 1)#slider_1 data.SetReal(10202, 1)#slider_2 data.SetReal(10203, 1)#slider_3 self.d = data.GetReal(10200) self.a = data.GetReal(10201) self.b = data.GetReal(10202) self.c = data.GetReal(10203) def Message(self, node, type, data) : tag = node instance = tag.GetDataInstance() if (type == c4d.MSG_DESCRIPTION_POSTSETPARAMETER) : if self.d != instance.GetReal(10200) : self.d = instance.GetReal(10200) changea = self.d*self.a instance.SetReal(10201, changea) changeb = self.d*self.b instance.SetReal(10202, changeb) changec = self.d*self.c instance.SetReal(10203, changec) else: if self.a != instance.GetReal(10201) : self.a = instance.GetReal(10201) if self.b != instance.GetReal(10202) : self.b = instance.GetReal(10202) if self.c != instance.GetReal(10203) : self.c = instance.GetReal(10203) print self.a, self.b, self.c, self.d, "final"That´s what you want, I guess?
(By the way, in the the script you´ve posted keep an eye on avoiding divisions by zero.)Cheers,

Okay. That worked! However, the console would display some errors saying that self.d didn't exist. So I put it in a try/except. Is that a safe way to fix it?

Hi,
I actually can´t see a reason why self.d didn´t exist, if the variables where initialized correctly.
Please post the whole thing or send me a private message.In my plugin it works like a charme.
