    Hi,

    I want to create a global matrix port on an object node. Currently thats my code:

    > \>             DescID cubeid = DescID(DescLevel(GV_OBJECT_OPERATOR_GLOBAL_OUT)); \>             portID =     GvCall(ot->GetOperatorData(), GetMainID)(ot, GV_PORT_OUTPUT, cubeid); \>             if(portID==NOTOK) return FALSE; \>              \>             Bool ok = ot->AddPortIsOK(GV_PORT_INPUT, portID); \>             if(ok==FALSE) return FALSE; \>

    I use the constans of the file: gvoperator.h
    But nothing happens. Is this the correct way?

    Thanks for your help.

    Cheers, Shawni

    You just pass the port ID to AddPortIsOK and AddPort.

    Example:

    > \> if (node->AddPortIsOK(GV_PORT_INPUT, GV_OBJECT_OPERATOR_GLOBAL_IN)) \> { \>      GvPort \*port = NULL; \>      port = node->AddPort(GV_PORT_INPUT, GV_OBJECT_OPERATOR_GLOBAL_IN, GV_PORT_FLAG_IS_VISIBLE, TRUE); \> \>      if (port) \>      { \>           //do something \>      } \> } \>

    cheers,
    Matthias

    Hi Matthias,

    yes, this works fine (I tested yesterday). The problem is, that AddPort just takes a LONG value so a real DescID element is not possible ( to create a Position.X port). So I tried to merge these cases. GvCall just returns 0 on a global matrix, but works fine when I just pass a DescID element which points to a Subchannel Port (like Vector.x)

    Just subports like ports of the Math Node doesnt work yet, but this is another problem I have to check. This is just a "stupid" workaround, but it seems to work. Do you think thats still ok?

    Cheers, Sebastian
