Hi,
i'm happy about my first steps in COFFEE :-)
I want to make a Rig-Generator.
Now the Bone generate and named and set at right position in hierarchie.
Now I need the Mocca-IK Tags at the Objects.
 
May way to do this is to use "command"->IK-Setup.
doc- >SetActiveObject(myBoneObject);
CallCommand(100001324);

It is ok, but I want to add my own mocca-IK Tag at every object.
And I need to add Expresso-Tags, too.
 
But how can I ma ke add Tags to Objects ?
This is the way I try:
var tobject =  doc->FindObject ( tagobj );
 if ( !tobject ) return;
 doc->SetActiveObject(tobject); 
 tobject->AllocTag("Texpresso");
 
Error is shown: [FAIL] 'ERIG' Line53: Incompatible Values...   NIL / OBJECT

Oh, please Help me ...
 
I search in this forum, in C4D-Treff and cg-talk(C4D) and found nothing.
Is here nobody who nows how I add a tag to an exist object?

For one, doc->FindObject(x) wants either a Marker or a String name for 'x'. As best I can tell, a Marker is equivalent to the LONG id in the C++ SDK. So you should have a number or the object's name (in double-quotes) there. You don't mention what 'tagobj' represents.

Secondly, BaseObject (tobject) does not have an AllocTag() method and the type isn't a string (it's an int, to be pedantic). It is part of BaseTag, so just do this:

var tag = AllocTag(Texpresso);
tobject->InsertTag(tag);

For beginners (and even some of us veterans), the forum search feature sometimes leaves a lot to be desired. :)

HTH,

Wow, that is it!
"FindObject" is the problem.
Don't run:

    
    
    main(doc, op)  
    {  
    var tobject =  doc->FindObject ( op );  
     if ( !tobject ) return;  
    var tag = AllocTag(Texpresso);  
    tobject->InsertTag(tag);  
    }

[b]That's run:[/b]

    
    
    main(doc, op)  
    {  
    var tag = AllocTag(Texpresso);  
    op->InsertTag(tag);  
    }

I generate the objects by myself at runtime of the coffee-Script.
I don't use C or C++ - only R9.5 Coffee-Console!
to create the Objekt I use this Code:

    
    
    var Bone = new(BoneObject);  
    Bone->SetName("Objekt1");  
    doc->InsertObject(Bone,NULL,NULL);  
    

You write: "So you should have a number or the object's name (in double-quotes) there. "
Is "Objekt1" the name I can use?
Or how can I get the Number of the object?

Yes, if you are using FindObject() by its name, use "Objekt1". Note that, according to the documentation, if there are multiple objects with the same name, it will always return the first one.

I don't know much about these so-called COFFEE 'Markers'. Here is a function used by the base class of many other classes, from the documentation:

BaseList2D::GetMarker()  
{Marker} GetMarker();   
Returns a unique marker that can be used to locate the object during runtime. Markers are only only valid while the program is running.

So, it appears that right after you create+insert your new object, you should get a Marker and store it:

var Bone = new(BoneObject);  
Bone->SetName("Objekt1");  
doc->InsertObject(Bone,NULL,NULL);  
// var BoneMarker declared somewhere with larger scope  
BoneMarker = Bone->GetMarker();

The problem is in scope persistence. Note that the Marker is only valid while the program is running. You could just as easily store 'var Bone' globally, maybe in an array, to get at your objects.

So, with that said, if the object names are going to remain unique, you should consider using FindObject("name") instead of FindObject(Marker).

Thanks again :-)
While I wait for answer I thought about anather way. You called now too.
When I create objekt I want to store it in a variable.
But my create-routine is in a function.
And its looks like variables in a function(){} are isolate.
When I create a variable in main(){} I cant get it in the function.
 
I search in SDK, but I don't found anything about global variables.
 
I have a funcion for generateBone() and for generateBoneUnderAnother().
I want store the objects in variables, but the counter in the functions start by "0" every call function.
 
Where can I found how can I make global variables?

Global variables are declared outside of functions. Don't know if this is possible in the Console, but you would do it like this (assumes that there are a maximum number of bones to allocate as an array) :

var Bones = new(array,64);  
  
...  
  
main()  
{  
}

You could also put the declaration in main() and fill the variable from the function return value:

generateBone()  
{  
     var Bone = new(BoneObject);  
     ...  
     return Bone;  
}  
  
main()  
{  
     var Bone = new(array,64);  
     for (var j = 0; j < 64; j++)  
     {  
          Bone[j] = generateBone();  
     }  
}

Yes, outside the main() makes global.

    
    
      
    var objid = new(array,20);  
     
    
    
    
    
    main()
    
    
    
    
    {
    
    
    
    
    }

is not possible?!
A global array?
In this array I want store Boneobjects.
Is it possible ?
I read in SDK, that this is possible:
 
Bevor I take your time with more questions, there are some basic Questions.
That must be possible for my AutoRig-Script.
Can I add Mocca-IK Tags to a objects? (I found in the SDK only the basic C4D-Tags to add)
Another Way, when I can't create Mocca-IK tags, can I remove and copy exists?
With command() I can start the mocca-IK Setup to an object-hierarchie.
When I can copy and paste, and remove, it is ok, too!
Can I add nodes with connections to an Expresso-Tag?

You may have to place it into main() then or do it this way:

var Bones;

main(doc,op)
{
Bones = new(array,64);

Greate.
But I need Bone-Array as BoneObject structure.
I am so silly? Or is it so heavy?
 
I'm sorry, that I must ask again:

    
    
    var Bones, objc;
    
    
    
    
    setbone(vdoc, addname, Atag, Btag, Ctag)  
    {  
     objc++;  
     Bone[objc]=new(BoneObject);  
     Bone[objc]->SetName(addname);  
     vdoc->InsertObject(Bone[objc],NULL,NULL);   
    }
    
    
    
    
    main(doc,op)  
    {  
    objc=-1;  
    Bones = new(array,64);  
    setbone (doc, "Arm[00]", NULL, NULL, NULL);  
    }

Why doesn't work ?

@mikael sterner
you say its impossible to add MOCCA-IK tags through COFFEE.
But what about if i use a Plugin *.cof written in COFFEE, and use that plugin to create my starting scene with all the objects and their tags...
Is it then possible to create "foreign" tags??

Yes, the answer is unfortunately no. To add Mocca_IK tags or to alter Xpressions you need to use C++.
