Public Types | |
enum | HierarchyMatchFlags { HMF_ok_part_extra = 1, HMF_ok_anim_extra = 2, HMF_ok_wrong_root_name = 4 } |
This enum defines bits which may be passed into check_hierarchy() and PartBundle::bind_anim() to allow an inexact match of channel hierarchies. This specifies conditions that we don't care about enforcing. More... | |
Public Member Functions | |
__init__ (PartGroup parent, str name) | |
Creates the PartGroup, and adds it to the indicated parent. The only way to delete it subsequently is to delete the entire hierarchy. More... | |
bool | applyControl (PandaNode node) |
Specifies a node to influence this particular joint so that it will always hold the node's transform. Returns true if this is a joint that can be so controlled, false otherwise. More... | |
bool | applyFreeze (const TransformState transform) |
Freezes this particular joint so that it will always hold the specified transform. Returns true if this is a joint that can be so frozen, false otherwise. More... | |
bool | applyFreezeMatrix (const LVecBase3 pos, const LVecBase3 hpr, const LVecBase3 scale) |
Freezes this particular joint so that it will always hold the specified transform. Returns true if this is a joint that can be so frozen, false otherwise. More... | |
bool | applyFreezeScalar (float value) |
Freezes this particular joint so that it will always hold the specified transform. Returns true if this is a joint that can be so frozen, false otherwise. More... | |
bool | clearForcedChannel () |
Undoes the effect of a previous call to apply_freeze() or apply_control(). Returns true if the joint was modified, false otherwise. More... | |
PartGroup | copySubgraph () |
Allocates and returns a new copy of this node and of all of its children. More... | |
PartGroup | findChild (str name) |
Returns the first descendant found with the indicated name, or NULL if no such descendant exists. This method searches the entire graph beginning at this PartGroup; see also get_child_named(). More... | |
PartGroup | getChild (int n) |
Returns the nth child of the group. More... | |
PartGroup | getChildNamed (str name) |
Returns the first child found with the indicated name, or NULL if no such child exists. This method searches only the children of this particular PartGroup; it does not recursively search the entire graph. See also find_child(). More... | |
list | getChildren () |
AnimChannelBase | getForcedChannel () |
Returns the AnimChannelBase that has been forced to this joint by a previous call to apply_freeze() or apply_control(), or NULL if no such channel has been applied. More... | |
int | getNumChildren () |
Returns the number of child nodes of the group. More... | |
bool | isCharacterJoint () |
Returns true if this part is a CharacterJoint, false otherwise. This is a tiny optimization over is_of_type(CharacterType::get_class_type()). More... | |
PartGroup | makeCopy () |
Allocates and returns a new copy of the node. Children are not copied, but see copy_subgraph(). More... | |
sortDescendants () | |
Sorts the children nodes at each level of the hierarchy into alphabetical order. This should be done after creating the hierarchy, to guarantee that the correct names will match up together when the AnimBundle is later bound to a PlayerRoot. More... | |
write (Ostream out, int indent_level) | |
Writes a brief description of the group and all of its descendants. More... | |
writeWithValue (Ostream out, int indent_level) | |
Writes a brief description of the group, showing its current value, and that of all of its descendants. More... | |
![]() | |
object | __reduce__ () |
object | __reduce_persist__ (object pickler) |
str | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string. Returns empty string on failure. More... | |
bool | encodeToBamStream (String data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. Returns true on success, false on failure. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. This counter is normally incremented automatically whenever the object is modified. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients. More... | |
![]() | |
TypeHandle | getType () |
Derived classes should override this function to return get_class_type(). More... | |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More... | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. More... | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. 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. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More... | |
bool | unref () |
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(). More... | |
![]() | |
__init__ (const Namable copy) | |
__init__ (str initial_name) | |
clearName () | |
Resets the Namable's name to empty. More... | |
str | getName () |
bool | hasName () |
Returns true if the Namable has a nonempty name set, false if the name is empty. More... | |
Namable | operator= (const Namable other) |
output (Ostream out) | |
Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this. More... | |
setName (str name) | |
Static Public Member Functions | |
static TypeHandle | getClassType () |
![]() | |
static TypedWritableReferenceCount | decodeFromBamStream (str data, BamReader reader) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. Returns NULL on error. More... | |

enum HierarchyMatchFlags |
__init__ | ( | PartGroup | parent, |

Creates the PartGroup, and adds it to the indicated parent. The only way to delete it subsequently is to delete the entire hierarchy.
bool applyControl | ( | PandaNode | node | ) |
Specifies a node to influence this particular joint so that it will always hold the node's transform. Returns true if this is a joint that can be so controlled, false otherwise.
This is normally only called internally by PartBundle::control_joint(), but you may also call it directly.
bool applyFreeze | ( | const TransformState | transform | ) |
Freezes this particular joint so that it will always hold the specified transform. Returns true if this is a joint that can be so frozen, false otherwise.
This is normally only called internally by PartBundle::freeze_joint(), but you may also call it directly.
