    Hi,

    I just have a small question. Is it possible to get the index or pointers of selected Keys in a CCurve?

    Thanks a lot.

    Cheers, Sebastian

    Use GetNBit() and ChangeNBit() with a key to determine and set the selection state in the four avaible timelines. The bits are:

    NBIT_TL1_SELECT
    NBIT_TL2_SELECT
    NBIT_TL3_SELECT
    NBIT_TL4_SELECT

    cheers,
    Matthias

    Not sure why but when I try using the GetNBit(NBIT_TL1_SELECT) like you mentioned above, I keep getting false returned even though I see the key selected.

    Here is a snippet of code

    //Set Curr_Key to first found key
    Curr_Key =Curr_Seq->GetKey(0);
    //Loop through all the keys on this track
    while(Curr_Key )
    {                         GePrint(LongToString(Curr_Key->GetTime().GetFrame(GetActiveDocument()->GetFps())));
                             GePrint(LongToString(Curr_Key->GetNBit(NBIT_TL1_SELECT)));

    //When an active key                if(Curr_Key->GetNBit(NBIT_TL1_SELECT)     || Curr_Key->GetNBit(NBIT_TL2_SELECT) || Curr_Key->GetNBit(NBIT_TL3_SELECT) || Curr_Key->GetNBit(NBIT_TL4_SELECT))
    {
    //DO something
    GePrint("ENTERED");
    }

    I have confirmed that the keys exist and the 1st GePrint statement show print the value of their time. But the second one always comes up as zero/false. And I cannot get into the above if statement. Any advice?

    Howdy,

    Since GetNBit() is accessing bits, you probably need to do this instead:

    > \> GePrint(LongToString(Curr_Key->GetNBit() & NBIT_TL1_SELECT) \>

    Adios,

    DOH! Sorry, I was thinking of a different function, so disregard what I posted above. :o(

    Sorry but I can't confirm. This is working fine for me.

    Oh ok, well I see it when I select a key in keymode, but when I try switching to Fcurve mode it only displays the keys that are selected in Keymode not the keys I select in Fcurve mode. Any thoughts?

    Thanks,

    For F-Curve keys use these:

    NBIT_TL1_SELECT2
    NBIT_TL2_SELECT2
    NBIT_TL3_SELECT2
    NBIT_TL4_SELECT2

    At some point these bits will be documented in a proper way. But for now you have to go by the name, they are usally quite self-explanatory.

    cheers,
