Hello,

I looking for a syntax to do something like that:

  
main(doc,op)   
{   
var obj=doc->FindObject("Cube");   
obj=CallCommand(12233);   
}

How can I use a command at an object? In my syntax only the selected one in the object-manager get edit.

Most likely, the command will work on selected objects. Therefore, once you find the object, you will want to select it. Selection is done using:

obj->SetBit(BIT_AOBJ);

Since other objects may be selected in the document, you may also want to deselect them so that the command only affects that object.

There is already a way to do this in COFFEE though.

SendModelingCommand(MCOMMAND_CURRENTSTATETOOBJECT);

A bit more fiddly, but then you set the object to affect directly instead of needing to activate the object and deactivate everything else (which, under certain circumstances, could be a long recursive list).

Thank you, obj->SetBit(BIT_AOBJ); works well.

When I use that command to create an Instance-Object, how can I decide where the new instance put in (hierarchy)?

What do I wrong?
CallCommands() in if-functions does not work.

main(doc,op)   
{   
var Strebe=doc->FindObject("1Strebescbhk");   
var cStrebe=op#ID_USERDATA:1;   
if (cStrebe==1)   
     {   
     println("activated");   
     CallCommand(12113);        //deselect all   
     Strebe->SetBit(BIT_AOBJ);   
     CallCommand(5160);          //Instance-Object   
     op#ID_USERDATA:1 = 0;   
     }   
}

It print activated, it Select the Strebe-Object. CallCommands() get ignored?

It's probably better to allocate objects and insert them into the document manually. This way you can specify a hierarchy insertion point.

little example:

  
var cube = doc->FindObject("Cube");  
  
var instance = AllocObject(Oinstance); //allocates an object  
doc->InsertObject(instance,cube,NULL); //insert the allocted object under the 'cube' object  
  
instance#INSTANCEOBJECT_LINK = cube; //set the instance link

Btw. it looks like you are calling your code from an expression. It is forbidden to make scene changes, like inserting objects, from within an expression. It can crash CINEMA 4D.

cheers,
Matthias

Hey,

Thank you for your answer, it works well.
What do you mean with expression?
Maybe you can explain it? (in German )

Ich meine damit Tags, z.B. das COFFEE Tag oder COFFEE XPresso Node.
