Hi,
my first post here...
I want to make a custom tag for an 3d-engine exporter.
To do this, I have to define a new tag class by extending the
BaseTag class, right?
This is a first test with no additional functions:
_

    
    
    _
    
    
    
    
     class zSortTag: BaseTag  
    {  
    public:  
    zSortTag();  
    }  
      
    zSortTag::zSortTag() {  
    return super();  
    }  
     _

_
Now, when I try to apply this to an object (via object->InsertTag ), I get FALSE as result. What´s wrong with my class?

I think you need to add Edit() as well and return TRUE. (Otherwise C4D thinks that the user pressed Cancel in your dialog, so it creates no tag.)

this doesn´t work:

  
class zSortTag : BaseTag  
{  
public:  
zSortTag();  
Edit();  
}  
  
zSortTag::zSortTag() {  
return super();  
}  
  
zSortTag::Edit() {  
return TRUE;  
}

any clues?

thx,
Florian

Do Constructors need a return? I don't think so.

    
    
    
    
    zSortTag::zSortTag() {  
      super();  
    }

You also need a GetID() that returns a unique ID from PluginCafe.

Hmm, that's really strange. I have tags running with C.O.F.F.E.E. in R8. Here's a simple example that works for me:

    
    
    const var MYTAG_ID = 1011203;  
    var mytag_icon;
    
    
    
    
    class MyTag : ExpressionPluginTag  
    {  
    public:  
      MyTag();  
        
      GetID();  
      GetIcon();  
      Edit();  
      GetName();  
      Execute(doc, op);  
      GetHelpText();  
        
      MultipleAllowed();  
      DisplayAllowed();  
      UseMenu();  
    }
    
    
    
    
    MyTag::MyTag() { println("MyTag"); super(); }  
    MyTag::GetID() { println("GetID"); return MYTAG_ID; }  
    MyTag::Edit() { println("Edit"); return TRUE; }  
    MyTag::GetName() { println("GetName"); return "My Tag"; }  
    MyTag::Execute(doc, op) { println("Execute"); return TRUE; }  
    MyTag::GetHelpText() { println("GetHelpText"); return "My Tag"; }  
    MyTag::MultipleAllowed()   { println("MultipleAllowed"); return TRUE; }  
    MyTag::DisplayAllowed()    { println("DisplayAllowed"); return TRUE; }  
    MyTag::GetIcon() { println("GetIcon()"); return mytag_icon; }  
    MyTag::UseMenu() { println("UseMenu"); return TRUE; }
    
    
    
    
    main()  
    {  
      mytag_icon = new(BaseBitmap, PLUGINTAG_ICON_SIZE, PLUGINTAG_ICON_SIZE);  
      mytag_icon->SetPen(vector(0.2, 0.3, 0.7));  
      mytag_icon->DrawRect(0,0,PLUGINTAG_ICON_SIZE,PLUGINTAG_ICON_SIZE);  
      println("main");  
      Register(MyTag);  
    }

(The culprit might have been UseMenu().)

great!
I should have tried ExpressionPluginTag instead of extending BaseTag! that probably doesn´t work.

Thanks a lot for your help!
I think it will be no problem now, to build the tag I need.

Doh, didn't see that. PluginTag should be fine as well if you want to show up in the Tag menu instead of Expressions menu.
