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?
