Detailed Description

Function set for Newton Fields.

Function set for creation, edit, and query of Newton Fields.

A newton field pulls an object toward another with a force that is dependent on the mass of the object exerting the field. It follows Newton's Law of Universal Gravitation.

Constructor & Destructor Documentation

MFnNewtonField::~MFnNewtonField

(

)

[virtual]

Destructor.

Class destructor.

MFnNewtonField::MFnNewtonField	(	MObject &	object,
		MStatus *	ReturnStatus = NULL
	)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

• MS::kSuccess if the function set is successfully attached
• MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNewtonField::MFnNewtonField	(	const MDagPath &	object,
		MStatus *	ReturnStatus = NULL
	)

Constructor.

Class constructor that initializes the function set to the given constant MDagPath object.

Parameters:

[in]	object	The const MDagPath to attach the function set to
[out]	ReturnStatus	The return status

Status Codes:

• MS::kSuccess if the function set is successfully attached
• MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNewtonField::MFnNewtonField	(	const MObject &	object,
		MStatus *	ReturnStatus = NULL
	)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the return status

Status Codes:

• MS::kSuccess if the function set is successfully attached
• MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
