class | PandaNode::Children |
class | PandaNode::Stashed |
This TFormer maintains a list of rectangular regions on the screen that are considered special mouse regions; typically these will be click buttons.
When the mouse passes in or out of one of these regions, or when a button is clicked while the mouse is in one of these regions, an event is thrown.
Mouse events may also be suppressed from the rest of the datagraph in these special regions.
This class can also implement a software mouse pointer by automatically generating a transform to apply to a piece of geometry placed under the 2-d scene graph. It will move the geometry around according to the mouse's known position.
Finally, this class can keep a record of the mouse trail. This is useful if you want to know, not just where the mouse is, but the exact sequence of movements it took to get there. This information is mainly useful for gesture-recognition code. To use trail logging, you need to enable the generation of pointer events in the GraphicsWindowInputDevice and set the trail log duration in the MouseWatcher. Otherwise, the trail log will be empty.

void PandaNode::adjust_draw_mask | ( | DrawMask | show_mask, |
DrawMask | hide_mask, | ||
DrawMask | clear_mask | ||
) | [inherited] |
Adjusts the hide/show bits of this particular node.
These three parameters can be used to adjust the _draw_control_mask and _draw_show_mask independently, which work together to provide per-camera visibility for the node and its descendents.
_draw_control_mask indicates the bits in _draw_show_mask that are significant. Each different bit corresponds to a different camera (and these bits are assigned via Camera::set_camera_mask()).
Where _draw_control_mask has a 1 bit, a 1 bit in _draw_show_mask indicates the node is visible to that camera, and a 0 bit indicates the node is hidden to that camera. Where _draw_control_mask is 0, the node is hidden only if a parent node is hidden.
The meaning of the three parameters is as follows:
Wherever show_mask is 1, _draw_show_mask and _draw_control_mask will be set 1. Thus, show_mask indicates the set of cameras to which the node should be shown.
Wherever hide_mask is 1, _draw_show_mask will be set 0 and _draw_control_mask will be set 1. Thus, hide_mask indicates the set of cameras from which the node should be hidden.
Wherever clear_mask is 1, _draw_control_mask will be set 0. Thus, clear_mask indicates the set of cameras from which the hidden state should be inherited from a parent.

int TypedWritable::complete_pointers | ( | TypedWritable ** | p_list, |
BamReader * | manager | ||

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

This function will be called during the cull traversal to perform any additional operations that should be performed at cull time.
This may include additional manipulation of render state or additional visible/invisible decisions, or any other arbitrary operation.
Note that this function will *not* be called unless set_cull_callback() is called in the constructor of the derived class. It is necessary to call set_cull_callback() to indicated that we require cull_callback() to be called.
By the time this function is called, the node has already passed the bounding-volume test for the viewing frustum, and the node's transform and state have already been applied to the indicated CullTraverserData object.

Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

Returns an object that can be used to walk through the list of children of the node.

This object also protects you from self-modifying loops (e.g. adding or removing children during traversal), since a virtual copy of the children is made ahead of time. The virtual copy is fast--it is a form of copy-on-write, so the list is not actually copied unless it is modified during the traversal.

PandaNode::Stashed PandaNode::get_stashed | ( | Thread * | current_thread = Thread::get_current_thread() | ) | const [inline, inherited] |
Returns an object that can be used to walk through the list of children of the node.
When you intend to visit multiple children, using this is slightly faster than calling get_stashed() directly on the PandaNode, since this object avoids reopening the PipelineCycler each time.
This object also protects you from self-modifying loops (e.g. adding or removing children during traversal), since a virtual copy of the children is made ahead of time. The virtual copy is fast--it is a form of copy-on-write, so the list is not actually copied unless it is modified during the traversal.

bool PandaNode::has_selective_visibility | ( | ) | const [virtual, inherited] |
Should be overridden by derived classes to return true if this kind of node has some restrictions on the set of children that should be rendered.
Node with this property include LODNodes, SwitchNodes, and SequenceNodes.
If this function returns true, get_first_visible_child() and get_next_visible_child() will be called to walk through the list of children during cull, instead of iterating through the entire list. This method is called after cull_callback(), so cull_callback() may be responsible for the decisions as to which children are visible at the moment.

bool PandaNode::has_single_child_visibility | ( | ) | const [virtual, inherited] |
Should be overridden by derived classes to return true if this kind of node has the special property that just one of its children is visible at any given time, and furthermore that the particular visible child can be determined without reference to any external information (such as a camera).

Sets the "final" flag on this PandaNode.
If this is true, than no bounding volume need be tested below it; a positive intersection with this node's bounding volume is deemed to be a positive intersection with all geometry inside.
This is useful to quickly force a larger bounding volume around a node when the GeomNodes themselves are inaccurate for some reason, without forcing a recompute of every nested bounding volume.

Whatever values you specify here indicate the shape of the full screen, and the MouseWatcherRegions will be given in coordinate space matching it. For instance, if you specify (0, 1, 0, 1), then a MouseWatcherRegion with the frame (0, 1, 0, .5) will cover the lower half of the screen.

This child node no longer contributes to the bounding volume of the PandaNode, and is not visited in normal traversals. It is invisible and uncollidable. The child may later be restored by calling unstash_child().
This function returns true if the child node was successfully stashed, or false if it was not a child of the node in the first place (e.g. it was previously stashed).

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.

This method is provided for the benefit of classes (like MouseRecorder) that inherit from PandaMode and also RecorderBase.
It's not virtual at this level since it doesn't need to be (it's called up from the derived class).
This method acts very like write_datagram, but it writes the node as appropriate for writing a RecorderBase object as described in the beginning of a session file, meaning it doesn't need to write things such as children. It balances with fillin_recorder().
