@ello said in debugging question: when i hover for example RNDOFFSET in visual studio i get enum <unnamed>::RNDOFFSET = 1029 does this unnamed part cause something? No, it doesn't cause anything. It just means the symbol is defined in an unnamed enum. We avoid such nowadays (improved error checking, easier to debug), but they don't do any harm. furthermore, since this is a plugin collection the name RNDOFFSET is indeed used with another id in another plugin. does this play a role? i thought that only included files are taken into account? Well, I doubt so, but it may. The point is using unique IDs per BaseContainer. And to access a certain ID always with the same type (you could change the type, but let's leave this aside for now). So for a single BaseContainer Is try to make sure and check, that one ID (I mean the symbol or name like RNDOFFSET) is always accessed with the same type, and that no two symbols have identical ID values, so you do not access the same BaseContainer entry with two different names (lets say RNDOFFSET_INT and RNDOFFSET_VEC) but maybe different types. here is a screenshot for the actual issue From briefly looking at the screenshot on my mobile, it does not give me an additional clue. I recommend to add the debugger console to your layout. Usually we print some extra info there, when we run into a Critical Stop. Bye, Andreas

Hi, Are you using the Spline GUI inside a dialog? It looks like so if there's no arrow. If that's the case you can call SetLayoutMode(c4d.LAYOUTMODE_MINIMIZED) on the Spline custom GUI to change its layout to the minimized/spline element only.

Hi Roger, I'm jumping into this discussion simply because Andreas is busy at the moment. point 3: it's actually not possible to turn a polygon cache in a spline... you can only consider, but it's rather a hack more than an orthodox approach to use the caches points to create the line object which you would expect from a spline cache, but take it as "thinking loud". point 4: no chance to preserve the cache of a spline as a spline... it's like asking can i preserve the cache of a sphere as a sphere? Actually cache are meant to be the lowest-order geometry to be processed by the displaying pipeline. So surfaces gets tesselleted in points and triangles and mathematical curves in line segments. point 5: I don't get the point here, sorry: you said you used GetAndCheckHierarchyClone() so which objects are you referring you added in the dependency list? Best, Riccardo

@eziopan Thanks mate. It works as expected. @a_block Thanks. Will double check next time.

Hi, I'm glad this already got solved. I just wanted to mention, I have added code tags to the initial post. Cheers, Andreas

Hi @cmpxchh8b, No worries at all since it's one of your first posts, but please make sure to read and apply the rules defined on the following topics: How to Post Questions. (Add proper tags in your case) Q&A Functionality. Regarding your question, if an object gets the same priority it's from top to bottom. Then you can find valuable information about priority in the c4d help With the given example you mentioned in the post here is the execution order after some internal test. (First one is executed before the last one) Skin.1 (Called to some kind of prepass) Skin.2 Called to some kind of prepass) Polygon.1 Skin.1 Circle (ObjectData which return a Spline, Called to some kind of prepass) Circle (ObjectData which return a Spline, Called to return the cache) Null.1 Null.2 Null.3 Polygon.2 Skin.2 XPresso.1 XPresso.2 XPresso.3 Note that any ObjectData can be executed multiple time since you can call AddToExecution which allow you to add the current node at any time within the execution pipline. This is basically used to do some kind of prepass and postpass. Hope it's answers to your question. Cheers, Maxime.

Thank you for your answer！@m_adam Although object go back normal after i clicked 'Redraw' (I guess that's the reason）,it isn't make sure problem is 'refresh the viewport'. 'refresh the viewport' can also fix Priority error result . 'Shift Priority Tag' just effective Expression.It can't help. After asking questions，i try to use Python Tag to replace 'Spline Deformer Object' ,because Python Tag have Priority.Fortunately，even though it looks very complicated, but everything become ok!

@a_block Thanks for the update. Much appreciated!

Hey @darrellp as you figured out, it was not on the correct category. But in any case don't worry, maybe I was too harsh and unprecise, I'm sorry about that but in the end, as I said, you are new here, so don't worry if you break the posting rules the first times

@c4ds, don’t worry! Every steps (even the off-road one) make some progress, right? I appreciate the way you focusing on the problem solving, which I believe is also the wonderful thing of this forum: we do our best to solving the problem itself, discussing about the better/more accurate answers rather than “who is right, who is wrong”. Last but not least, thank you for taking time to reply!

Thank you all, great answers! I will take a different approach. I convert the circle to a spline and then divide that spline into the wanted number of points. -Pim

@s_bach I was beginning to wonder if I was beating my head against a brick wall. Apparently so. Thanks so much for alleviating the pain! Well, I learned quite a bit about Python in the process so not really a loss. Guess I'll try moving on directly to the C++ version.

Hello and welcome, when creating a new post, please use tags and the Q&A system. See Read Before Posting. I tried your code in a R20 script and it seems to work perfectly fine: rd = doc.GetActiveRenderData() if rd is None: return fromSlice = rd[c4d.RDATA_FRAMEFROM] toSlice = rd[c4d.RDATA_FRAMETO] fps = doc.GetFps() print(fromSlice.GetFrame(fps)) print(toSlice.GetFrame(fps) What exactly is not working for you? In what context do you execute your code? best wishes, Sebastian

@s_bach said in SortedArray() - "Namespace Maxon has no member class "SortedArray": #include "maxon/sortedarray.h" Great, thanks to the both of you. Next time, I will mark it as a question. -Pim

Hello and welcome, what exactly do you mean with "export keyframe data"? Do you want to write data into a file? The best way to develop such code would be in a Python script that you can edit and execute in the Script Manager. A XPresso Python node is meant to contain code that is executed as part of XPresso to define the behavior of the XPresso network. A XPresso Python node should not be used to modify the scene or to perform I/O operations. A CTrack object stores the DescID of the associated parameter. You can access that DescID with GetDescriptionID(). Alternatively you can use BaseList2D.FindCTrack() to search for the CTrack associated with a certain parameter DescID. You find an example on GitHub. You find general information on how to use CTrack and DescID also in the C++ documentation: CTrack Manual DescID Manual best wishes, Sebastian

Hi ello, no, you don't need to worry, the compiler won't check the remaining lines. It is a warning, we use internally to make people write better code. Usually smaller functions are easier to maintain and thinking about how to properly split and slice your code leads to better better results. By the way, compilers nowadays do quite a good job on inlining functions, so one does not need to be afraid of performance issues. But in the end this is probably also a matter of personal taste and so you can configure this in your projectdefinition.txt. See the Stylecheck options in our Project Tool documentation, there you have the option to set the maximum line count for functions (stylecheck.max-linecount=number). Please consider the use of tags and of our Q&A system. Cheers, Andreas

Hi Mike, please check this thread to properly use the Q&A functionality. Cheers, Riccardo

@m_adam Hi, Thanks for your answer. I applied your changes and it worked like a charm . Thanks again!!!

Hello, Indeed this example is wrong. We will fix that as soon as possible. Thanks for noticing us. best wishes, Sebastian
