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.

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

Search for all occurrences

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]	full	the full (or long) name of the attribute
[in]	brief	the brief (or short) name of the attribute
[in]	unitType	an element of the MFnUnitAttribute::Type enum
[in]	defaultValue	the default value for the new attribute
[out]	ReturnStatus	MS::kSuccess the new attribute was created successfully MS::kFailure the new attribute was not created MS::kInvalidParameter the type parameter was invalid

Returns:

An MObject representing the new attribute

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

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.

Parameters:

[in]	full	the full (or long) name of the attribute
[in]	brief	the brief (or short) name of the attribute
[in]	child1	a numeric attribute
[in]	child2	a numeric attribute
[in]	child3	a numeric attribute (optional)
[out]	ReturnStatus	MS::kSuccess the new attribute was created successfully MS::kFailure the new attribute was not created MS::kInvalidParameter the given child objects were not all numeric attributes or one or more of them has already been added to the node

Returns:

An MObject representing the new attribute
