So , no bug!
From support (thanks!), while rendering the scene is duplicated so I can still use the scene for editing. This means thing can get shuffled around.

To get the actual Tag (with the UserData faders in this case) I have to use.

GetFirstTag(obj, type)
{
    var tag = obj->GetFirstTag();
    while (tag) {
      if (tag->GetType() ==type) return tag;
      tag = tag->GetNext();
    }
    return NULL;
}

To get the first COFFEE tag, you should use then:

var coffeeTag = GetFirstTag(myObj, Tcoffeeexpression);

And this should work. Of to try it out...

Hm.
I've spent some hours making this work but no go...

I think I have tried every possible variation of the code above.

I either get "Variable or Function expected" (In the brackets of the very first and very last line of the code above)
or
when there iare no errors the code doesn't work..

If anyone sees anything strange or know how to aproach this I'd be very happy.

To recap.
In the end I need to get the UseData from sliders placed on the Tag when rendering. In editor it works.

I can't confirm this. The following seems to work fine here: (with my user data at :1)

    
    
    GetFirstTag(obj, type)  
    {  
        var tag = obj->GetFirstTag();  
        while (tag) {  
          if (tag->GetType() == type) return tag;  
          tag = tag->GetNext();  
        }  
        return NULL;  
    }
    
    
    
    
    main(doc,op)  
    {  
     println(GetFirstTag(op,Tcoffeeexpression)#ID_USERDATA:1);  
    }

Yup it works (for me as well) in printing to console as well as editor animation.
But it still doesn't animate the op (a Camera in this case) when rendering or making a render preview.

I will try again in a minimalistic scene.

Hi,

I was just wondering if you had overloaded the copy(), read(), write(), functions in the tag. I assume you have or it doesn't need it though, because you said it works with a very simple set up. I also haven't used the R9 COFFEE SDK. Sorry if this is a dumb question, but I just thought I'd mention it.

Good luck.

I certainly must be missing something obvious here...
If I put another Tag as first tag, then the Coffe tag is not found.

It all stops at the line:
tag=tag->GetNext();

with the error:
(9) Member not found
File: expression
Line:7

So in my case it is still the same problem and I'm at loss atm.

And it was of coarse my fault!
I had misspelt GetNext (typed getNext)
It was still gray in the expression editor (should it be that) so I missed it.
-and- it worked in editor..
Let me apologize and thanks for the help.

@Aaron. I totaly missed your post. Thanks for the input.
No copy,read,write() was / is involved, this was in a clean coffe tag test setup.

To finally get it into work in a cof file I put the Tagchecking code in its own "apartment" before Execute.

Cheers

What do you mean by "apartment?" A function? Just wondering.

Hi, like this:

public:

GetFirstTag(obj,type);
Execute(doc,op);

PluginName::GetFirstTag(obj,type);
{
the code
}

PluginName::Execute(doc,op);

etc.

Next worry is that now, when it is a expressionplugin (.cof),
I need to move the UserData faders to the plugintag (instead of the "old" COFFEE Tag)

In the code to get the UserData on the COFFEE there is the line:
var coffeetag = GetFirstTag(op,Tcoffeeexpression);
I'm trying to get the plugin tag instead..(replaceing Tcoffeeexpression)

In the SDK there are the options:
-Tplugin (it gets red in the ExpressionManager but don't work, for me)
-Tcoffeeplugin (doesn't get red and doesn't work, for me)
-Texpressionplugin(doesn't get red and doesn't work, for me)

(The final code is of coarse writen into the text.cof file. I just load it into a in active COFFEE tag to see better the code while test typing)

I suppose I miss something here...(as usual)...

To recap. I need to place UserData on the new PluginTag (That this expression plugin make)
The method used for getting the UserData from a regular COFFEE Tag doesn't seem to apply.

(The choise to use UserData faders/sliders is so far on purpose, ease of
use and the ability for the user to customize each instance while keeping entries low)

Thanks and Cheers

None of those. To get your own plugin tags from an object, use the unique Plugin ID that you received (or one of the specified range of test ones if you have not gotten one yet).

So, if you declared the Plugin ID somewhere like this:

enum  
{  
MYPLUGIN_ID = 12345678  
}

Do this:

var myplugintag = GetFirstTag(op, MYPLUGIN_ID);

At least this is how it works in the C++ SDK. It is possible that you may need to check using instanceof() and instead of using the Plugin ID, you would use the plugin class name:

// Your plugin tag class derivative  
class MyPluginTag : PluginTag  
{  
};  
  
// Wherever you're searching for your plugin tag on 'op'  
var tag;  
// Go through object 'op' tags  
// - Note that the for loop has no body.  
// - It ends when there are no more tags on 'op' or one of yours is found  
for (tag = op->GetFirstTag(); tag && !instanceof(tag, MyPluginTag); tag = tag->GetNext());  
if (!tag) println("None of my tags found!");

I think this is probably more like what COFFEE would expect.

Hi, and thanks. It looks as if using the Plugin ID works fine in my first tests today. I did try it yesterday but must have done something wrong then.

Hi everyone. I´m still working on my "bone" tag. I have changed the user data links into dialogs and containers, in order to have a full regular tag.
But I had a strange problem: when I render in the viewer, I get just the first deformation of my scene, not the whole animation.
It is amazing, but if I put my code in a default c4d coffee tag, everything goes well, except that I have to search the objects by their names, instead of getting them from a user area. I suppose that it's a harder way for c4d to get them this way. Have someone any idea?
My code is a bit more organized since I posted it, and it works faster. I still draw the vertex weights by hand, but it's not so difficult that for the default c4d bones. I could post my c4d version of the p3 woman, but I don´t know if it is legal, so I will make a menu plugin that import a Poser-exported .obj and copyes my rigging...

Ive got the same problem (works in editor but not in render) and I just cant fix it.
My spin on the problem is that my coffee is running in a coffee node inside an xpresso tag.
And ive tried using the getfirsttag() method listed above. (I ported my code into a expressiontagplugin, and (when c4d decides its in the mood to run it) it did work. But not from within my coffee node.
Ive also tried searching for objects and their tags using different methods, specifying them hardcoded by hand, you name it (to simulate the getfirsttag solution above)
Ive tried putting userdata items on my xpresso tag, on the object that contains the xpresso tag, hardcoding my values into variables inside the code, passing my userdata items in via xpresso.
All methods work for getting my data into my coffee - lots of println()'s show the data its processing on is fine, file names of files im reading are fine, the values being processed are fine.
But..... Nothing! Always works in the editor - not the renderer.
Note: I want this to be run specifically from inside c4d - not from a plugin. And I cant run it from a coffee tag as they dont support the file operations (really suprises me the file reading limitations in a cofee tag)
Does anyone have any ideas? Im all out
Many thanks
