Search for all occurrences

Retrieves the name of the plugin class.

This name is usually used internally for debugging purposes. For Material plug-ins this method is used to put up the material "type" name in the Material Editor.

Parameters:

s	Reference to a string filled in with the name of the plugin class

Retrieves a constant that uniquely identifies the plugin class.

This method must return the unique ID for the plugin class. If two ClassIDs conflict, the system will only load the first conflicting one it finds. A program (gencid.exe) is provided to generate unique class id values.

Returns:: A class id that uniquely identifies a plugin class

See also:: Class ClassID, List of Class IDs.

Reimplemented from Animatable.

Reimplemented in MSSimpleManipulatorXtnd.

{ return pc->class_id; }

int NumSubs ( ) [inline, virtual]

Search for all occurrences

Remarks:: The system uses a virtual array mechanism to access the sub-anims of a plug-in. This method returns the total number of sub-anims maintained by the plug-in. If a plug-in is using a parameter block to manage its parameters it should just return 1 for all the parameters directed by the parameter block.

Returns:: The number of sub-anims used by the plug-in.

Default Implementation:: { return 0; }

Reimplemented from SimpleManipulator.

Reimplemented in MSSimpleManipulatorXtnd.

{ return pblocks.Count() + SimpleManipulator::NumSubs(); }

Animatable* SubAnim ( int i ) [virtual]

Search for all occurrences

Remarks:: This method returns a pointer to the 'i-th' sub-anim. If a plug-in is using a parameter block to manage all its parameters it should just return a pointer to the parameter block itself from this method. This method may return NULL so developers need to check the return value before calling other sub anim methods (such as SubAnimName()).

Parameters:

i	This is the index of the sub-anim to return.

Default Implementation:: { return NULL };

Reimplemented from SimpleManipulator.

Reimplemented in MSSimpleManipulatorXtnd.

MSTR SubAnimName ( int i ) [virtual]

Search for all occurrences

Remarks:: This method returns the name of the 'i-th' sub-anim to appear in track view. The system has no idea what name to assign to the sub-anim (it only knows it by the virtual array index), so this method is called to retrieve the name to display. Developer need to make sure the 'i-th' SubAnim() is non-NULL or this method will fail.

Parameters:

i	The index of the parameter name to return

Returns:: The name of the 'i-th' parameter.

Reimplemented from SimpleManipulator.

Reimplemented in MSSimpleManipulatorXtnd.

int NumParamBlocks ( ) [inline, virtual]

{ if (id == I_MAXSCRIPTPLUGIN) return (MSPlugin*)this; else return Manipulator::GetInterface(id); }

RefResult NotifyRefChanged	(	Interval	changeInt,
		RefTargetHandle	hTarget,
		PartID &	partID,
		RefMessage	message
	)		`[inline, virtual]`

Search for all occurrences

Receives and responds to messages.

A plugin which makes references must implement a method to receive and respond to messages broadcast by its dependents. This is done by implementing NotifyRefChanged(). The plugin developer usually implements this method as a switch statement where each case is one of the messages the plugin needs to respond to. The Method StdNotifyRefChanged calls this, which can change the partID to new value. If it doesn't depend on the particular message& partID, it should return REF_DONTCARE.

For developer that need to update a dialog box with data about an object you reference note the following related to this method: This method may be called many times. For instance, say you have a dialog box that displays data about an object you reference. This method will get called many time during the drag operations on that object. If you updated the display every time you'd wind up with a lot of 'flicker' in the dialog box. Rather than updating the dialog box each time, you should just invalidate the window in response to the NotifyRefChanged() call. Then, as the user drags the mouse your window will still receive paint messages. If the scene is complex the user may have to pause (but not let up on the mouse) to allow the paint message to go through since they have a low priority. This is the way many windows in 3ds Max work.

Parameters:

changeInt	- This is the interval of time over which the message is active. Currently, all plug-ins will receive FOREVER for this interval.
hTarget	- This is the handle of the reference target the message was sent by. The reference maker uses this handle to know specifically which reference target sent the message.
partID	- This contains information specific to the message passed in. Some messages don't use the partID at all. See the section List of Reference Messages for more information about the meaning of the partID for some common messages.
message	- The message parameters passed into this method is the specific message which needs to be handled.

Returns:: The return value from this method is of type RefResult. This is usually REF_SUCCEED indicating the message was processed. Sometimes, the return value may be REF_STOP. This return value is used to stop the message from being propagated to the dependents of the item.

Reimplemented from SimpleManipulator.

                    { 
                        SimpleManipulator::NotifyRefChanged(changeInt, hTarget, partID, message); 
                        return ((MSPlugin*)this)->NotifyRefChanged(changeInt, hTarget, partID, message); 
                    }

int NumRefs ( ) [virtual]

Search for all occurrences

Returns the total number of references this ReferenceMaker can hold.

The plugin implements this method to indicate the total number of of references it can make. This includes all references whether they are NULL (inactive) or non-NULL (active) at the time when this method is called. A plugin can hold a variable number of references, thus the return value of this method is not to be cached and reused by client code.

Returns:: The total number of references this plugin can hold. The default implementation is return 0.

Reimplemented from SimpleManipulator.

Reimplemented in MSSimpleManipulatorXtnd.

RefTargetHandle GetReference ( int i ) [virtual]

Search for all occurrences

Returns the 'i-th' reference.

The plugin implements this method to return its 'i-th' reference. The plug-in simply keeps track of its references using an integer index for each one. This method is normally called by the system.

Parameters:

i	- The index of the reference to retrieve. Valid values are from 0 to NumRefs()-1.

Returns:: The reference handle of the 'i-th' reference. Note that different calls to this method with the same 'i' value can result in different reference handles being retrieved, as the plugin changes the scene objects it references as its 'i-th' reference.

Reimplemented from SimpleManipulator.

Reimplemented in MSSimpleManipulatorXtnd.

virtual void SetReference	(	int	i,
		RefTargetHandle	rtarg
	)		`[protected, virtual]`

Search for all occurrences

Stores a ReferenceTarget as its 'i-th' reference`.

The plugin implements this method to store the reference handle passed to it as its 'i-th' reference. In its implementation of this method, the plugin should simply assign the reference handle passed in as a parameter to the member variable that holds the 'i-th' reference. Other reference handling methods such as ReferenceMaker::DeleteReference(), or ReferenceMaker::ReplaceReference() should not be called from within this method. The plugin itself or other plugins should not call this method directly. The system will call this method when a new reference is created or an existing one is replaced by calling ReferenceMaker::ReplaceReference().

Parameters:

i	- The index of the reference to store. Valid values are from 0 to NumRefs()-1.
rtarg	- The reference handle to store.

RefTargetHandle Clone ( RemapDir & remap ) [virtual]

Search for all occurrences

This method is used by 3ds Max to clone an object.

See also:

CloneRefHierarchy(), class RemapDir This method is called by 3ds Max to have the plugin clone itself. The plug-in's implementation of this method should copy both the data structure and all the data residing in the data structure of this reference target. The plugin should clone all its references as well. Also, the plug-in's implementation of this method must call BaseClone(). In order for classes derived from this class to clone cleanly, the Clone method should just create the new instance, and then call an implementation of BaseClone that clones the references and copies any other necessary data. For example:

            class MyDerivedPlugin
                : public MyBasePlugin
            {
                const int MY_REFERENCE = 1;

                ReferenceTarget* Clone(RemapDir& remap)
                {
                    ReferenceTarget* result = new MyDerivedPlugin();
                    BaseClone(this, result, remap);
                    return result;
                }

                void BaseClone(ReferenceTarget* from, ReferenceTarget* to, RemapDir& remap)
                {
                    if (!to || !from || from == to)
                        return;    
                    MyBasePlugin::BaseClone(from, to, remap);
                    to->ReplaceReference(MY_REFERENCE, remap->CloneRef(from->GetReference(MY_REFERENCE)));
                }
            };

This method should not be directly called by plug-ins. Instead, either RemapDir::CloneRef() or CloneRefHierachy() should be used to perform cloning. These methods ensure that the mapping from the original object to the clone is added to the RemapDir used for cloning, which may be used during backpatch operations

Note:: See the remarks in method BaseClone() below.

Parameters:

remap - A RemapDir instance used for remapping references during a Clone.

Returns:: A pointer to the cloned item.

Reimplemented from ReferenceTarget.

void BeginEditParams	(	IObjParam *	ip,
		ULONG	flags,
		Animatable *	prev
	)		`[virtual]`

Search for all occurrences

Remarks:: This method is called by the system when the user may edit the item's (object, modifier, controller, etc.) parameters.

Parameters:

ip	Interface pointer. The developer can use it to call methods such as AddRollupPage(). Note that this pointer is only valid between BeginEditParams() and EndEditParams(). It should not be used outside this interval.
flags	Describe which branch of the command panel or dialog the item is being edited in. The following are possible values: BEGIN_EDIT_CREATE Indicates an item is being edited in the create branch. BEGIN_EDIT_MOTION Indicates a controller is being edited in the motion branch. BEGIN_EDIT_HIERARCHY Indicates a controller is being edited in the Pivot subtask of the hierarchy branch. BEGIN_EDIT_IK Indicates a controller is being edited in the IK subtask of the hierarchy branch. BEGIN_EDIT_LINKINFO Indicates a controller is being edited in the Link Info subtask of the hierarchy branch.
prev	Pointer to an Animatable object. This parameter may be used in the motion and hierarchy branches of the command panel. This pointer allows a plug-in to look at the ClassID of the previous item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel, but simply update the values displayed in the UI fields. This prevents the UI from 'flickering' when the current item begins its edit. For example, if you are in the motion branch and are looking at an item's PRS controller values, and then select another item that is displayed with a PRS controller, the UI will not change - only the values displayed in the fields will change. If however you selected a target camera that has a lookat controller (not a PRS controller) the UI will change because a different set of parameters need to be displayed. Note that for items that are edited in the modifier branch this field can be ignored.

void EndEditParams	(	IObjParam *	ip,
		ULONG	flags,
		Animatable *	next
	)		`[virtual]`

Search for all occurrences

Remarks:: This method is called when the user is finished editing an objects parameters. The system passes a flag into the EndEditParams() method to indicate if the rollup page should be removed. If this flag is TRUE, the plug-in must un-register the rollup page, and delete it from the panel.

Parameters:

ip	An interface pointer. The developer may use the interface pointer to call methods such as DeleteRollupPage().
flags	The following flag may be set: END_EDIT_REMOVEUI If TRUE, the item's user interface should be removed.
next	Animatable pointer. Can be used in the motion and hierarchy branches of the command panel. It allows a plug-in to look at the ClassID of the next item that was being edited, and if it is the same as this item, to not replace the entire UI in the command panel. Note that for items that are edited in the modifier branch this field can be ignored.
