Manuel, thanks for taking the time and posting some links. Last night I was reading up on the Matrix and trying wrapping my head around it. I think I was stuck in the wrong area, I was trying to convert a baseObject to a pointObject to do the transformations.I would perfer not to have to open the axis window, but instead handle all this in a Python Function. I will look over the docs and samples to get a better idea of what I need to do. Thanks again for taking the time to respond to my post!

@esan said in OperatorSetData for "Lists"?: Another quick question. is there still a bug on c4d.GV_OBJECT_OPERATOR_OBJECT_OUT? Yes it's still there and being R20 maintenance ended it's likely to remain. Best, R

@r_gigante Thanks for this info. In two of my plugins I am already handling the TagData::Message to check for point and polygon changes (and other things as well). To my understanding, all this would be performed on the object remaining after the merge. What happens to the objects being merged "into" the remaining object, and especially the tags assigned to them. I am still wondering how to actually be able to merge the data from the other tags. Say you have 3 objects: cube. sphere, cylinder. Each has a custom tag assigned. To keep it simple let's say that the tag stores a user specified value. User has entered value 10 for the cube, 15 for the sphere, 12 for the cylinder. Now, when the 3 objects get merged (via connect or connect + delete or SendModelingCommand(MCOMMAND_JOIN ..., ...) the end result is the cube object receiving all the polygons and points, etc ... from all 3 objects. Internally the UVW tag is merged, etc ... The custom tag from the original cube remains as is, with value 10, and could react to i.e. MSG_POLYGONS_CHANGED in the TagData::Message. But ... how and where would I be able to handle the merging of values 15 and 12 into the custom tag ? Only when perform a SendModelingCommand(MCOMMAND_JOIN ... am I able to actively merge the values, as I know which objects will be merged, and thus can obtain the values from their tags before the joining is performed. With a connect or connect + delete, how to know about the other objects, and especially their custom tags? I don't expect this to be available inside a TagData::Message

Correct, You can then process this as a standard Cinema 4D drag operation and react to BFM_DRAGRECEIVE in your GeUserArea Message method. You can retrieve it from BFM_INPUT_X and BFM_INPUT_Y def InputEvent(self, msg): mouseX = msg[c4d.BFM_INPUT_X] mouseY = msg[c4d.BFM_INPUT_Y] As you will do in a normal drag process so in your Message method override. InputEvent is only called with BFM_INPUT, so if you want to do something before handling the drag, then do it previously and avoid HandleMouseDrag. Hope it helps, Cheers, Maxime.

Hello, Q2 : filterwhirl.cpp is a internal file you don't have access to it. And we don't have tutorials. (this comment will be removed to avoid confusion) Q3 : CallCommand should be use on the main thread, that's maybe why it's not working, you can use ExecuteOnMainThread in your job. Cheers, Manuel

Thanks, sounds a bit complicated, so I have to give it some thoughts. For now, it is enough. -Pim

@mp5gosu said in Treeview and Right Click: RemoveData() Great, thanks.

Thanks, great explanation! One small issue. Delete doesn't work because objParent' is not defined. Traceback (most recent call last): File "scriptmanager", line 251, in DeletePressed NameError: global name 'objParent' is not defined Here the code that, I think, solves the issue: def DeletePressed(self, root, userdata): "Called when a delete event is received." for tex in reversed(list(TextureObjectIterator(self.listOfTexture))): if tex.IsSelected: objParent = tex.GetParent() # Added listToRemove = objParent.GetChildren() if objParent is not None else self.listOfTexture listToRemove.remove(tex)

@m_magalhaes Thanks for bringing this up, as it seems I had overlooked it on multiple occasions. Which also points me to the fact that the R19 SDK did have a String::operator == () Also overlooked that all those years. I need better glasses.

Thanks, it is clear to me now. I am using str(opUuid).encode("hex") now.

Sorry I was not clear enough. Your answer (polygon object is "enabled" by definition) triggered me and now I understand. Thanks and my best wishes for a great 2020 for you, your family and your Maxon family. -Pim

@s_bach said in Communication between DescriptionTool and GeUserArea: The typical modern approaches are patterns like Model-View-Controller or Model-View-Presenter. In such models, you don't "send data around". Thanks for mentioning this. As stated in my opening post, this is what I have been using, where the "model" is a singleton class, available as a global variable to all plugins to synchronize and share data. Maybe not quite the exact wording. I was just wondering if there is another means of providing this "model" instead of using an instanced (singleton) class via a global variable? So in your example, the interaction with the DescriptionToolData would write data into the model. And the GeUserArea would read that data from the model. The example I provided isn't making use of a "model" as it already represented too much code just to point out the bug that slipped into R21. There I indeed used a very simplified solution by "sending data around". But an overall "thank you" for bringing up the model-view discussion, as this made me realize I could use an observer pattern in another project of mine which would fix its current poorly chosen design.

@m_adam said in GeUserArea lag in R21 versus R20: Thanks a lot for reporting this kind of issues, it's really relevant for us :) My wife is "jokingly" telling me to send in an invoice for all the effort I am spending in "beta-testing" this official public release. Not so sure if she really means it as a joke, or just being sarcastic ...

@kbar @m_adam Thanks for the help lads, the markers were already added thanks to Kent suggestion in his previous reply. Now the only things left are a little "GlTF-fighting", and some more polishing, packaging and testing before updating the plugin with a - hopefully - nice animation support ! I'll let you know when that's done (probably not before 2020 though ). Cheers, Loïc

@m_adam said in Reverse iterators, how to use them?: Hi @C4DS Here the message from the development team which confirms what I said to you previously. Hi Maxime, I didn't doubt what you said earlier. I only wanted to point out that it wasn't clear from reading the documentation which collection could be used with reverse iterators. It's nice mentioning in the documentation about RBegin/REnd, Range based loops, etc ... but not everyone looks into the collection implementation to see which types do have RBegin/REnd or are range based, ... HashMap doesn’t support -- so you can’t use a reverse iterator for that. It wouldn’t make sense anyway because HashMap iteration is unordered. Having used std::map some might expect HashMap to be ordered, but it isn't mentioned anywhere it isn't. But the point has been made, and it is now clear how to use reverse iterator. Topic well be closed as "solved".

@s_bach Okay I will give it a try , and I will do a open source example project for anyone, who would love to do this with python only for Cinema 4D. lol I been making different types c4d python plugins for 3 years now, from 2015 for my studio I work for and I love making c4d plugins. But this will be my first time using GeUserArea Class to the fullest lol.

Hello Sorry for the delay, Christmas time didn't helped. I've opened a bug entry for that issue. I'll be back when i'll have more information. I've added the "Bug report" tag to this thread Cheers, Manuel

Thanks for the update Frank. Looking at your "resolutions" I think that the actions you took were responsible, in the first case, to clean the existing derived data for the R20 project, whilst in the second, to refresh the DerivedData subfolder where the newly re-created R21 project was supposed to store intermediate files. Please keep us updated and for the mean time I'm going to set this thread as solved. Cheers

Hello Sebastian, I now understand what the difference is, thank you very much! With the customdata_customgui example file I actually made both a GUI and a custom DataType. So I only needed to change my resource file and modifiy my data code a bit! Best Regards, Florian
