hello,

i am using op->AddDependence(hh, child); and op->TouchDependenceList(); to hide the child objects of my object plugin. works fine as long as i dont use my object plugin as a child of another of my object plugins

e.g.
-plugin
--cube

works, the cube is invisible

plugin
-plugin
--cube

the cube is visible

i guess that it is a common mistake of mine which is causing this, any ideas?

thanks and cheers,
ello

Look into the SDK and search for GetAndCheckHierarchyClone()

ok, after checking the GetAndCheckHierarchyClone... i got the dependencies working for nested pluginobjects properly but always the child of the nested object isnt hided anymore. what do i need to do that none of those child objects is visible (without using SetEditorMode/SetRenderMode )??

thanks for your patience :)

code at the beginning regarding the dirty thing:

\>

`

at the end of the generator (right before the return main;) i have this code:
> `

  
\>         
\>       op->NewDependenceList();   
\>       child = op->GetDown();  
\>       for (tp=child;tp;tp=tp->GetNext())   
\>       {  
\>            op->AddDependence(hh,tp);  
\>       }       
\>       op->TouchDependenceList();  
\>       return main;  
\>

`

Hm, don't know because I do it totally different in my plugin. I never used TouchDependencyList ;-) Maybe you'll have to iterate the hierarchy and touch all children yourself.

GetAndCheckHierarchyClone() does use it, so i thought its a good idea.. i'll do some more tests what happens when i remove it, but u thought it belongs there to hide the childs

i'll try the iterating again, maybe i did something wrong last night

thanks for your input

well, CompareDependenceList needs to be there, otherweise even the first child isnt hidden.

iterating the hierarchy doesnt help, or is this the wrong was to do so?

It looks like your are not going through all of the children objects. Here is some simple working sample code:

Yes, some good old recursing action! To understand recursions, you first have to understand recursions. But once that's done, they're fun :)
