Documentation

Description

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

A drag field exerts a friction, or braking force, proportional to the speed of a moving object.

Functions

MFnDragField:: MFnDragField ()

Description

Default class constructor. The function set is not attached to an MObject.

MFnDragField:: MFnDragField ( MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

• object the MObject to attach the function set to
• ReturnStatus the return status
  • 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

MFnDragField:: MFnDragField ( const MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

• object the const MObject to attach the function set to
• ReturnStatus the return status
  • 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

MFnDragField:: MFnDragField ( const MDagPath & object, MStatus * ReturnStatus )

Description

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

Arguments

• object the const MDagPath to attach the function set to
• ReturnStatus the return status
  • 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

MFn::Type MFnDragField:: type () const

Description

Return the type of this function set.

Return Value

• the constant MFn::kDrag

MFnDragField:: ~MFnDragField ()

Description

Class destructor.

MVector MFnDragField:: direction ( MStatus * ReturnStatus ) const

Description

Returns the direction of the drag force's influence along the x, y, and z axes. You must have the Use Direction setting turned on for this attribute to take effect.

Arguments

• ReturnStatus Status code

Return Value

• A vector representing direction.

Status Codes

• MS::kSuccess The method was successful.
• MS::kFailure An object error has occurred.

MStatus MFnDragField:: setDirection ( const MVector & dragDirection )

Description

Sets the direction of the drag force's influence along the x, y, and z axes. You must have the Use Direction setting turned on for this attribute to take effect.

Arguments

• dragDirection A vector representing direction.

Return Value

• Status code

Status Codes

• MS::kSuccess The method was successful.
• MS::kFailure An object error has occurred.

bool MFnDragField:: useDirection ( MStatus * ReturnStatus ) const

Description

Returns true if the braking force is exerted only against the component of the object's velocity that lies along the direction of the drag force.

Arguments

• ReturnStatus Status code

Return Value

• true Use the direction setting to determine the braking force.
• false Use the objects velocity to determine the braking force.

Status Codes

• MS::kSuccess The method was successful.
• MS::kFailure An object error has occurred.

MStatus MFnDragField:: setUseDirection ( bool enable )

Description

Enables the braking force to be exerted only against the component of the object's velocity that lies along the direction setting of the drag force.

Arguments

• enable Flag to enable or disable direction setting.

Return Value

• Status code

Status Codes

• MS::kSuccess The method was successful.
• MS::kFailure An object error has occurred.
