Detailed Description

Numeric attribute function set.

MFnNumericAttribute is the function set for dependency node attributes that store one, two or three untyped numeric values. A numeric attribute supports both a "hard" maximum/minimum and a soft maximum/minimum. The soft maximum/minimum are used by the Attribute Editor as the limits on its slider, but values within the hard range can be typed in the input box.

As a convenience, MFnNumericAttribute will set the flags of child attributes as well when the flags of the parent attribute are set. This is important when creating a numeric pair or triplet. For example, if MFnNumericAttribute is used to create a 3 double attribute and the attribute is set to be keyable, then the three child attributes will also be marked as keyable.

Member Function Documentation

MFn::Type type ( ) const [virtual]

Function set type.

Return the class type : MFn::kNumericAttribute.

Reimplemented from MFnAttribute.

const char * className ( ) const [protected, virtual]

Class name.

Return the class name : "MFnNumericAttribute".

Reimplemented from MFnAttribute.

MObject create ( const MString full,
const MString brief,
MFnNumericData::Type  unitType,
double  defaultValue = 0,
MStatus ReturnStatus = NULL 
)

Create a new numeric attribute and return it as an MObject.

If the attribute create is of a type that stores two or more values, then a compound attribute will be created. The names of child attributes will have "0", "1" and "2" appended to both the full and brief names. As well, each child will use the defaultValue parameter as its default.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

Parameters:
[in]fullthe full (or long) name of the attribute
[in]briefthe brief (or short) name of the attribute
[in]unitTypean element of the MFnUnitAttribute::Type enum
[in]defaultValuethe default value for the new attribute
[out]ReturnStatus
Returns:
An MObject representing the new attribute

MObject createColor ( const MString full,
const MString brief,
MStatus ReturnStatus = NULL 
)

Create a new color attribute and return it as an MObject.

The names of child attributes will have "r", "g" and "b" appended to both the full and brief names.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

Parameters:
[in]fullthe full (or long) name of the attribute
[in]briefthe brief (or short) name of the attribute
[out]ReturnStatus

MObject createPoint ( const MString full,
const MString brief,
MStatus ReturnStatus = NULL 
)

Create a new point attribute and return it as an MObject.

The names of child attributes will have "x", "y" and "z" appended to both the full and brief names.

The create method needs to be called on a per node basis. That means if you want to create and add the same attribute to multiple nodes, you need to call the create method for each node to get a unique MObject back. If you call create just once and add the attribute to multiple nodes, Maya will encounter a fatal error.

Parameters:
[in]fullthe full (or long) name of the attribute

const MObject child1,
const MObject child2,
const MObject child3 = MObject::kNullObj,
MStatus ReturnStatus = NULL

This form of the create method allows the creation of a compound attribute having two or three numeric child attributes. All of the child attributes must be of the same type (eg all of type kDouble) and must already have been created but not yet added to the node.

It is also possible to use angle and distance attributes created with MFnUnitAttribute. These attributes will act the same as a double attribute.
