Hi guys.. not long ago i came across the "Bool GetNBit(LONG bit) const" Function. It is in the manual, and is probably exactly what you need ( if it works correctly )

Ah! Then one must also use ChangeNBit() for this. Thanks for the info Michael!....well, if it works

Already looked at the *NBit() methods. They are for 64-bit bitfields - if that were to have any bearing on a 32-bit version of Cinema 4D, strange.

How would you use these fields anyway? For instance, the Object Manager fold is represented by four LONG fields. What do you check here - for all of them to be non-zero? No further information.

That info seems misleading.. it probably just means that you have 64 "flags". You should be able to do sth. like GetNBit(NBIT_OM1_FOLD) or ChangeNBit(NBIT_OM1_FOLD,NBIT_SET
) without problems on any architecture. It is not possible to combine the bits though. GetNBit(NBIT_OM1_FOLD | NBIT_OM2_FOLD) is illegal ( see definition of these constants in ge_prepass.h )

I guess that the four fold bits correspond to the four different object managers.

It does seem to work.

But what do you mean by 'the four different object managers'? I know that you can have more than one OM, but have not seen any other type of OM. Oh I see - you can have up to four OMs open (previous descriptions sounded like there could be any number opened).

I guess that I'll continue in the current vane and just get/set/del all four of them - poor users.

Looking at these NBIT fields, do you notice that all (except for the OM ones) are timeline related - ALL of them: TL=TimeLine, FC=F-Curve, CKEY= (well) CKey? The natural question arises - why is the Object Manager folding now tied directly to the TimeLine?

Thanks,
Robert

With this information in hand, anyone care to speculate how you would determine which of the four possible OMs (Scene Browsers - I take it from ManagerInfo) is the active one?

Robert -
I ran into the same issue you did while doing a tutorial based on 9.6.
I'm a newb at scripting in COFFEE and I was able to get most of the script to work by changing CallCommand #'s, the only thing that drives me crazy is the folded hierarchy that SetBit, DelBit, ToggleBit don't seem to phase. Any results with that other GetNBit function vs. the 4 OM's? (I don't completely understand the syntax - just hoping you've found something).

This is the code that I'm using (within a TreeViewFunctions that somewhat mirrors the OM - but not exactly). Note that I'm only interested in the one Object Manager and decided not to do it in any others that may be available.

Wow! Thank you very much Robert.  The code is a bit over my head, so I think I'll just manually expand my resulting hierarchy until I get a better handle on C4D scripting in R10.   At the moment, ChangeNBit doesn't even turn black in my script manager (ie doesn't appear to be a valid member function of Hypernurb or symmetry objects)...
The code I'm having trouble with (with redundant debugging here - I've tried both Del and SetBits:
///////////////////PROBLEM AREA.......
//hN is a hypernurb object
//sym is a symmetry object
hN->SetBit(BIT_OFOLD);          // doesn't work R10
sym->SetBit(BIT_OFOLD);          // doesn't work R10
println("Using SetBit and BIT_OFOLD ");
println(hN->GetBit(BIT_OFOLD));
hN->DelBit(BIT_OFOLD);
sym->DelBit(BIT_OFOLD);
println("Using DelBit and BIT_OFOLD ");
println(hN->GetBit(BIT_OFOLD));
hN->SetBit(NBIT_OM1_FOLD);   //idea from SDK R10, but doesn't work (64 bit OS only?)
sym->SetBit(NBIT_OM1_FOLD); //idea from SDK R10, but doesn't work (64 bit OS only?)
println("Using SetBit and NBIT_OM1_FOLD ");
println(hN->GetBit(NBIT_OM1_FOLD));
hN->DelBit(NBIT_OM1_FOLD);
sym->DelBit(NBIT_OM1_FOLD);       //appears to set bit for OM1, but doesn't seem to change folding
println("NBIT_OM1_FOLD after modification: ");
println(hN->GetBit(NBIT_OM1_FOLD)); //confirms FOLD bit change 1 to 0 but no change in display OM
//hN->ChangeNBit(NBIT_OM1_FOLD, NBIT_SET); //ChangeNBit apparently not valid member function nH (Hypernurb object)
//sym->ChangeNBit(NBIT_OM1_FOLD, NBIT_SET);//or sym (symmetry object)

//////////////// .....END PROBLEM AREA

My code is C++ only. Don't know about COFFEE in R10 - it looks to be still R9.5 support only. Hopefully one of the dev support users can provide more information in this case.

Thanks, Robert. Ah, the assumption I made was that scripting would be similar to plugin C++ syntax. I thought I could practice with scripts before jumping in to plugins. I learned something anyway. Thanks.
