Passing Objects Into A Custom Command In The API

[Robert Bateman]

use MSyntax::setObjectType(kSelectionList) and it should be pretty apparent. Just because the args it gives you from MArgDataBase::getObjects() comes in the form of a selection list, doesn't mean that selection list has been passed to MGlobal::setActiveSelectionList().

Thanks for the reply but im still having problems and its driving me nuts!!

So far i have this code and descriptions as to what i THINK should happen within my plugin, which compiles nicely and loads into maya no problems

MSyntax RoadConnectCmd::newSyntax()

{

syntax.setObjectType(MSyntax::kSelectionList);

return syntax;

}

MStatus RoadConnectCmd::doIt ( const MArgList &args)

{

MStatus stat;

MDagPath dagPath;

MArgDatabase argData; //Creates An Argument Database To Store All The Objects Passed Through The Command

MSelectionList passedObject; //Creates A Maya Selection List And Populates It With The Object Passed From The Command

argData.getObjects(passedObject); //Gets The Objects from the argument database and populates the MSelectionList passedObjects



passedObject.getDagPath(0, dagPath); //Gets The DagPath of The Objects Passed Into The Command







return redoIt();

}



however when i try and run the command RoadConnect() whilst trying to pass an object into the procedure

eg.
Road Connect(pSphere1);

maya has a fit and i get the error message

// Error: RoadConnect(pSphere1); //

// Error: Invalid use of Maya object "pSphere1". //

Ive only been coding for about 6 months so if you or anyone could elaborate further it would be much appreciated.

oops duplicated message

[Robert Bateman]

tried calling the mel command like so ?

RoadConnect "pSphere1" ;

Also have a closer look at the way you are using MSyntax & MArgDataBase. currently it's not parsing the args at all. Check out the Function7 example here :

Thanks again
