Hi,

I have written a generator object, that returns a virtual hierarchy.

I can also create clones of objects that create clones themselves (e.g. the Array Object) as shown here:
_<_img border="0" src= "http://www.c4d-jack.de/projects/spread/cloning_problem_1.jpg"_>_

It is also possible to put my object into another cloning object (again like e.g. the Array Object) :<_<_img border="0" src= "http://www.c4d-jack.de/projects/spread/cloning_problem_3.jpg"_>_pg">

But here comes the first problem: It is not possible for me to create clones of my own object, see he_<_img border="0" src= "http://www.c4d-jack.de/projects/spread/cloning_problem_2.jpg"_>__2.jpg">

That's the first problem. What can I do here? Is there something I have to do? I just create clones of the source object(s) by using obj- >GetClone(0, NULL); and then inserting the cloned object into the virtual hierarchy, which I return in ::GetVirtualHierarchy().

+ + + + + + + + + + + + +

2nd Problem:
As you can also see on the sceenshots 1 and 3, my source objects are still visible. I do obj->Touch() on all ob them after creating the clones, but that does only hide the top object. If I have a whole hierarchy which I clone (like the Array Object on screenshot 1) only the Array Object gets hidden, but the Sphere Object stays visible. Do I have to iterate the object's whole hierarchy and touch every object I find, or is there a nicer way?

Thanks for any help I am really stuck here

Best regards & greetings,
Jack

OK, already got it. Have to use the AliasTrans class, too.

But since I do this, I have several memory leaks. If I comment the whole AliasTrans stuff away, no leaks appear in the c4d trace window.

It seems Free(at) is not enough. Anything else to do here?

Cheers,

The memory leaks are probably because you forget to free the AliasTrans here.

Does anybody know something about my 2nd Problem? Do I really have to iterate the whole hierarchy and touch every object?

Hi Jack,

use GetAndCheckHierarchyClone() instead. No need for dependence lists etc. then. It handles the hiding and touching too.

Use it like this.

> BaseObject\* down = op->GetDown(); if(!down) return BaseObject::Alloc(Onull); \> down = op->GetAndCheckHierarchyClone(hh, down, HCLONE_ASPOLY, &dirty;, NULL, TRUE); \> \> if (!dirty) return down;

You will get a null-object with all the objects of your hierarchy cloned underneath it. Decide with HCLONE_ASPOLY what you want the hierarchy clones to be (HCLONE_ASIS for example to simply get clones, not converted to polys...see doc for more info).

Now go on coding.
