Constructor & Destructor Documentation

~MFnPointLight

(

)

[virtual]

Destructor.

The class destructor.

MFnPointLight	(	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

MFnPointLight	(	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

MFnPointLight	(	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

MObject create	(	bool	UIvisible = true,
		MStatus *	ReturnStatus = NULL
	)

Search for all occurrences

Creates a new point light dependency graph node and adds it to the dependency graph.

If the UIvisible parameter is true, the new node will be connected to the light classification node (which allows the UI to recognize the node as a light) and added to the default light list. If UIvisible is false, the node will be created in isolation.

The light node is added to the current model, under a new transformation.

Parameters:

[in]	UIvisible	determines whether or not to connect the new node to the light classification node and add it to the default light list.
[out]	ReturnStatus	return status

Returns:

MObject representing the new dependency node.

Status Codes:

• MS::kSuccess operation successful
• MS::kInsufficientMemory ran out of memory
• MS::kNoModelActive no model is currently active
• MS::kLicenseFailure application not licensed for attempted operation
• MS::kFailure the new node could not be added to the model, or the function set could not be properly initialized with the new object.

MObject create	(	const MObject &	parent,
		bool	UIvisible = true,
		bool	wantTransform = false,
		MStatus *	ReturnStatus = NULL
	)

Search for all occurrences

Creates a new point light dependency graph node and adds it to the dependency graph.

If the UIvisible parameter is true, the new node will be connected to the light classification node (which allows the UI to recognize the node as a light) and added to the default light list. If UIvisible is false, the node will be created in isolation.

If wantTransform parameter is false ( which is by default ), the new shape node is created under the specified parent and no transform node is created. If the specified parent is null, then no shape node will be created.

The light node is added to the current model, under the specified parent.

Parameters:

[in]	parent	the node under which the new light and its transform will be added.
[in]	wantTransform	Boolean to indicate whether the transform node is needed or not, which is 'false' by default.
[in]	UIvisible	determines whether or not to connect the new node to the light classification node and add it to the default light list.
[out]	ReturnStatus	return status

Returns:

MObject representing the new dependency node.

Status Codes:

• MS::kSuccess operation successful
• MS::kInsufficientMemory ran out of memory
• MS::kNoModelActive no model is currently active
• MS::kLicenseFailure application not licensed for attempted operation
• MS::kFailure the new node could not be added to the model, or the function set could not be properly initialized with the new object.

NO SCRIPT SUPPORT.

Creates a new point light dependency graph node and adds it to the dependency graph.

If the UIvisible parameter is true, the new node will be connected to the light classification node (which allows the UI to recognize the node as a light) and added to the default light list. If UIvisible is false, the node will be created in isolation.

The light node is added to the current model, under a new transformation. The transformation is added to the current model under the specified parent.

Parameters:

[in]	parent	the node under which the new light and its transform will be added.
[in]	UIvisible	determines whether or not to connect the new node to the light classification node and add it to the default light list.
[out]	ReturnStatus	return status

Returns:

MObject representing the new dependency node.

Status Codes:

• MS::kSuccess operation successful
• MS::kInsufficientMemory ran out of memory
• MS::kNoModelActive no model is currently active
• MS::kLicenseFailure application not licensed for attempted operation
• MS::kFailure the new node could not be added to the model, or the function set could not be properly initialized with the new object.
