Hi there,

anyone knows an example or where to look in the manual for creating an input field where i can drag more than one object? Like the one in the lights scene-tab? I dont even know how its properly called.. so i guess that would help, too

cheers and thanks in advance,
Ello

i think you mean in_exclude. you find it in the sdk docs under "Description resource".

Oh yeah, the lovely InExcludeData ^^
Be careful, it can be a real b*tch...

Generally, if you want to create a GUI *like* some other GUI you saw in other plugins or modules, it's always a good idea to take a look into the .res files and learn from them.

here i get the InExcludeData:

\>  InExcludeData *mylist = (InExcludeData* )bc->GetCustomDataType(CHILDLIST,CUSTOMDATATYPE_INEXCLUDE_LIST);  
\>  if (!mylist ) goto Error;  
\>

`

and than i try this:
> `

  
\>  ccnt++;  
\>  if (ccnt>objcnt) ccnt = 0;  
\>  child=(BaseObject* )(mylist->ObjectFromIndex(doc,ccnt))->GetClone(COPY_NO_BITS, NULL);   
\>

`

the last line is where it crashes.. i searched the forum but didnt got results about cloning objects of InExcludeData

Make sure ccnt is in the correct range (10 objects, ccnt MUST be between 0 and 9!!!). So, if ccnt==objcnt, that would equal 'crash'. Just like it says in the docs:

(0 <= lIndex < GetObjectCount())

*G, thank you. i really did that here:
if(ccnt>objcnt) ccnt=0;
instead
if(ccnt==objcnt) ccnt=0;

now everything works like it should.. cool

`

in the one plugin i can delete the last object at least from the IN_EXCLUDE field with no crash (deleting it from the scene still crashes), in the other plugin this doesnt help

edit: ok, now it works like this on both plugins, but well, deleting from the scene

Yep, the funny InExclude list doesn't notice if a linked object has been deleted. Therefore, the "dead" link remains in the list, and ListCount is not updated, either. You have to write your own function to check the links, remove dead ones and correct the listcount

Maybe i'll do it in another way.. i think atm. InExclude is not the best choice for what i wanted to do.. But i'll do a separate testplugin where i can learn those things...

thanks for the indepth
