Acccessing Inexclude Data

c4d.InExcludeData it is all there. There also multiple threads here on PC dealing
with the InExcludeData class. Nothing really out of the ordinary here. Only thing
worth mentioning is, that you should always construct an instance with an
existing instance, otherwise funny things tend to happen, despite the fact the
parameter is flagged optional in the docs. -

Thanks! I am however still unable to get it done. I must mention at this point that i'm a beginner.
I have this . res file:
CONTAINER Omlr { NAME Omlr; INCLUDE Obase; GROUP ID_OBJECTPROPERTIES { GROUP { BOOL DE_ACTIVATE {} BUTTON VISUAL_REP {} } IN_EXCLUDE LAYER_ONE_INEX {} IN_EXCLUDE LAYER_TWO_INEX {} IN_EXCLUDE LAYER_THREE_INEX {} } }and this .h file:
#ifndef _Oatom_H_ #define _Oatom_H_ enum { Omlr = 1029977, DE_ACTIVATE = 1000, VISUAL_REP = 1001, LAYER_ONE_INEX = 1002, LAYER_TWO_INEX = 1003, LAYER_THREE_INEX = 1004 }; #endifIf yomeone could tell me what code gets me an inexcludedata object with the objects droped in that list i would be really gratefull, because i just can't get it done
Thanks

Thanks! I think i kind of understand how to access things from the .res file. But i still can't get it to work, because i would like to trigger the printing of the inexclude list so to say with a button, in a Message function, which doesn't have op as a parameter (if any of this sounds wrong i'm sorry). Here is the code, hope it isn't too much of a bother:
import c4d from c4d import gui, plugins, documents import os PLUGIN_ID = 1029977 class MultiLayerRender(c4d.plugins.ObjectData) : def Execute(self, op, doc, bt, priority, flags) : return True def printInEx(op, doc) : inExcludeList = op[c4d.LAYER_ONE_INEX] print inExcludeList def createTags(self, op, doc) : self.printInEx(op, doc) doc = c4d.documents.GetActiveDocument() selection = doc.GetSelection() tagID = 5637 for hostObject in selection: existing = False tags = hostObject.GetTags() for tag in tags: if tag.GetType() == tagID: existing = True if existing == False: hostObject.InsertTag(c4d.BaseTag(tagID)) c4d.EventAdd() def VisibilityOn(self) : doc = c4d.documents.GetActiveDocument() selection = doc.GetSelection() tagID = 5637 for hostObject in selection: tags = hostObject.GetTags() for tag in tags: if tag.GetType() == tagID: tag[c4d.COMPOSITINGTAG_SEENBYCAMERA] = True def VisibilityOff(self) : doc = c4d.documents.GetActiveDocument() selection = doc.GetSelection() tagID = 5637 for hostObject in selection: tags = hostObject.GetTags() for tag in tags: if tag.GetType() == tagID: tag[c4d.COMPOSITINGTAG_SEENBYCAMERA] = False def Message(self, node, type, data) : # print "node: " + str(node) if type == c4d.MSG_DESCRIPTION_COMMAND: self.createTags(op, doc) # obviously "op" is not defined # self.VisibilityOn() # self.VisibilityOff() print "type: " + str(type) print "node: " + str(node) print "data: " + str(data) return True if __name__=='__main__': bmp = c4d.bitmaps.BaseBitmap() dir, file = os.path.split(__file__) fn = os.path.join(dir, "res", "Icon.tif") bmp.InitWith(fn) result = plugins.RegisterObjectPlugin( id = PLUGIN_ID, str = "MultiLayerRender", g = MultiLayerRender, description ="Omlr", info = c4d.OBJECT_GENERATOR, icon =bmp )All it gives me, is op is not defined. Including op in the Message parameters howvere doesn't work, i can't just add stuff there apparently.
I tried figuring out what to do with the help of other threads and the docs but i'm apparently not too good at gathering info yet - couldn't get it solved at all.
Hope this isn't completly wrong and thanks in advance!Aurel

Thanks littledevil and NiklasR for your help so far!
Forgetting the self there was really stupid of me -.- however, that doesn't do the trick either. printInEx takes3 arguments (self, op, doc) so i need to call it with those three. In createTags however "op" is not defined. So i have to add it to the list of parameters it takes as well, right? -> createTags(self, op, doc) but then i have to call it with those arguments in the Message method, and
def Message(self, node, type, data, op, doc) :
gives me an ERROR:
TypeError: Message() takes exactly 6 arguments (4 given)
Is there a way to solve that?

yes and no. you could implement message with op and doc as optional parameters.
def Message(self, node, type, data, op = None, doc = None) :
But i guess that is not what you want, because c4d still won't know that you
expect 6 parameters and call the method with 4 parameters. the only difference
would be that python won't raise an error and you could call the method from your
code with 6 parameters.but node and op are basically the same. so you can use node as a substiute.
and the document can be retrieved from node. with gelistnode.getdocument(). -

I made the following changes:
def Message(self, node, type, data, ) : if type == c4d.MSG_DESCRIPTION_COMMAND: self.printInEx(node) return TrueAnd
def printInEx(self, node) : myPluginNode = c4d.GeListNode.GetDocument(node) print myPluginNode[c4d.LAYER_ONE_INEX]That gives me the error:
AttributeError: 'module' object has no attribute 'LAYER_ONE_INEX'
I also tried using the ID which is 1002, no luck with that either. Could it be, that it doesn't find my .res or .h file or something?
Tahnks in advance!

and just for the record, when overwriting methods inherited from c4d api classes the naming
of the parameters does not make any difference, only the order matters, because c4d does not
call the methods with their keywords. you could overwrite message also this way.def Message(self, a, b, c) :
a(node) would be the the instance derived from gelistdnode of your plugin, a baseobject for
example. b(type) would be an integer and c(data) would be a basecontainer/pyobject.python is pretty unique when it comes to method parameters. you could define message also
this way.def Message(self, *args) :

It works so far, except that it still doesn't find LAYER_ONE_INEX.
my code ATM:

AttributeError: 'module' object has no attribute 'LAYER_ONE_INEX'Do i have to specifically include stuff from Omlr.res / .h? I find it hard to believe that it can be this hard to get that inexclude data - I feel like i'm doing something fundamentaly wrong.
EDIT:
I just noticed that
print doc[c4d.LAYER_ONE_INEX]Doesn't make much sense, because i don't need the document for that, sorry bout that ;/

It's just that I, being a beginner and all, thought that it's supposed to be
node[c4d.the name from the .h file]
but it's actualy
node[c4d.the ID associated with the name from the .h file]
so i first had to define LAYER_ONE_INEX = 10002 in the .pyp file XD
Sorry to bother you with such basic problems and THANK you a lot

you have to init your attribute as i wrote. read c4d.plugins.NodeData.Init()
and c4d.plugins.NodeData.InitAttr() you do not have to define the ID in your
py file again. -

Allright, i will do that! btw. As an obviously pretty expirienced plugin creator, what's in your oppinion the best way of becoming better and understanding the general concept behind cinema? because i would have never thought of looking in those places:
c4d.plugins.NodeData.Init() and c4d.plugins.NodeData.InitAttr()
And i most of the time find the plugins more confusing than helping ;(

i don't think there is any easy way to learn the c4d api, but it is easier than it might look
on the first glance. simply read the documenation. i started with scripts and added stuff
as i needed it. you should know and understand the basic principles of oo-programming,
when you to start writing plugins for c4d (polymorphism and so on).those are the most important classes/modules in the python api. >> means read also any
class which inherits from this class.c4d.Matrix
