[Maya] Using MSyntax and MArgDatabase to handle the input parameters

Function:

Based on the previous code, implement the same function as before: create a bunch of cylinders along the selected curve.

 

Main Code:

Initialise the flags:

const char *numberFlag="-n", *numberLongFlag="-nmuber";
const char *radiusFlag="-r", *radiusLongFlag="-radius";
const char *heightFlag="-h", *heightLongFlag="-height";

doIt function:

MStatus Posts1Cmd::doIt(const MArgList &args)
{
    int nPosts=5;
    double radius=0.5;
    double height=5.0;

    MArgDatabase argData(syntax(),args);

    if(argData.isFlagSet(numberFlag))
        argData.getFlagArgument(numberFlag,0,nPosts);

    if(argData.isFlagSet(radiusFlag))
        argData.getFlagArgument(radiusFlag,0,radius);

    if(argData.isFlagSet(heightFlag))
        argData.getFlagArgument(heightFlag,0,height);

...

MSyntax function:

MSyntax Posts1Cmd::newSyntax()
{
    MSyntax syntax;
    syntax.addFlag(numberFlag,numberLongFlag,MSyntax::kLong);
    syntax.addFlag(radiusFlag,radiusLongFlag,MSyntax::kDouble);
    syntax.addFlag(heightFlag,heightLongFlag,MSyntax::kDouble);
    return syntax;
}

static MSyntax newSyntax();

Modification of initializations function:

stat=pluginFn.registerCommand("posts1", 

Posts1Cmd::creator, 

Posts1Cmd::newSyntax);
