Topic: version 4 MAXScript New Features/Scripted Plug-In
Two new event calls have been added to scripted plug-ins. If you provide handlers for these in your scripted plug-in body, they will be called when their corresponding event occurs.
on attachedToNode <nodeVar> do ...
Called whenever a scripted plug-in scene object (geometry, camera, light, helper, shape) is bound to a node in the scene, such as during create mode. The node that the current plug-in instance is being attached to is given as the first argument. In the event of scene node instancing, this handler may be called several times, whenever the base object is instanced to a node. Note that, in most cases, this will be called in the middle of a create mode and consequently, actions such as creating other nodes in the handler body are forbidden, as they are generally in 'on create' handlers.
on deleted do ...
Called whenever the scripted plug-in object is finally deleted. This may not occur immediately, such as when a scene node containing a scripted base object is deleted, since the object is held onto by the undo stack in case the node delete is undone by the user. The delete may occur when the undo stack is cleared, such file new or reset.
