Detailed Description
An animated character, with skeleton-morph animation and either soft- skinned or hard-skinned vertices.
Definition at line 38 of file character.h.
Member Function Documentation
◆ clear_lod_animation()
| void Character::clear_lod_animation | ( | ) |
Undoes the effect of a recent call to set_lod_animation().
Henceforth, the character will animate every frame, regardless of its distance from the camera.
Definition at line 343 of file character.cxx.
◆ combine_with()
Collapses this node with the other node, if possible, and returns a pointer to the combined node, or NULL if the two nodes cannot safely be combined.
The return value may be this, other, or a new node altogether.
This function is called from GraphReducer::flatten(), and need not deal with children; its job is just to decide whether to collapse the two nodes and what the collapsed node should look like.
Reimplemented from PandaNode.
Definition at line 134 of file character.cxx.
References TypedObject::is_exact_type().
◆ complete_pointers()
|
virtual |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
Reimplemented from PartBundleNode.
Definition at line 1120 of file character.cxx.
References PartBundleNode::complete_pointers().
◆ cull_callback()
|
virtual |
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.
The return value is true if this node should be visible, or false if it should be culled.
Reimplemented from PandaNode.
Definition at line 165 of file character.cxx.
◆ dupe_for_flatten()
|
virtual |
This is similar to make_copy(), but it makes a copy for the specific purpose of flatten.
Typically, this will be a new PandaNode with a new pointer, but all of the internal data will always be shared with the original; whereas the new node returned by make_copy() might not share the internal data.
Reimplemented from PandaNode.
Definition at line 119 of file character.cxx.
◆ find_joint()
| CharacterJoint * Character::find_joint | ( | const std::string & | name | ) | const |
Returns a pointer to the joint with the given name, if there is such a joint, or NULL if there is no such joint.
This will not return a pointer to a slider.
Definition at line 358 of file character.cxx.
◆ find_slider()
| CharacterSlider * Character::find_slider | ( | const std::string & | name | ) | const |
Returns a pointer to the slider with the given name, if there is such a slider, or NULL if there is no such slider.
This will not return a pointer to a joint.
Definition at line 376 of file character.cxx.
◆ force_update()
| void Character::force_update | ( | ) |
Recalculates the character even if we think it doesn't need it.
Definition at line 453 of file character.cxx.
◆ make_copy()
|
virtual |
The Character make_copy() function will make a new copy of the Character, with all of its joints copied, and with a new set of dynamic vertex arrays all ready to go, but it will not copy any of the original Character's geometry, so the new Character won't look like much.
Use copy_subgraph() to make a full copy of the Character.
Reimplemented from PandaNode.
Definition at line 107 of file character.cxx.
◆ merge_bundles()
| void Character::merge_bundles | ( | PartBundleHandle * | old_bundle_handle, |
| PartBundleHandle * | new_bundle_handle | ||
| ) |
Merges old_bundle_handle->get_bundle() with new_bundle.
old_bundle_handle must be one of the PartBundleHandle within this node. At the end of this call, the bundle pointer within the old_bundle_handle will be replaced with that within the new_bundle_handle pointer, and all geometry within this node will be updated to reference new_bundle.
Normally, this is called when the two bundles have the same, or nearly the same, hierarchies. In this case, new_bundle will simply be assigned over the old_bundle position. However, if any joints are present in one bundle or the other, new_bundle will be modified to contain the union of all joints.
The geometry below this node is also updated to reference new_bundle, instead of the original old_bundle.
This method is intended to unify two different models that share a common skeleton, for instance, different LOD's of the same model.

◆ register_with_read_factory()
|
static |
Tells the BamReader how to create objects of type Character.

◆ set_lod_animation()
| void Character::set_lod_animation | ( | const LPoint3 & | center, |
| PN_stdfloat | far_distance, | ||
| PN_stdfloat | near_distance, | ||
| PN_stdfloat | delay_factor | ||
| ) |
Activates a special mode in which the character animates less frequently as it gets further from the camera.
This is intended as a simple optimization to minimize the effort of computing animation for lots of characters that may not necessarily be very important to animate every frame.
If the character is closer to the camera than near_distance, then it is animated its normal rate, every frame. If the character is exactly far_distance away, it is animated only every delay_factor seconds (which should be a number greater than 0). If the character is between near_distance and far_distance, its animation rate is linearly interpolated according to its distance between the two. The interpolation function continues beyond far_distance, so that the character is animated increasingly less frequently as it gets farther away.
The distance calculations are made from center, which is a fixed point relative to the character node, to the camera's lod center or cull center node (or to the camera node itself).
If multiple cameras are viewing the character in any given frame, the closest one counts.
Definition at line 322 of file character.cxx.
◆ update()
| void Character::update | ( | ) |
Recalculates the Character's joints and vertices for the current frame.
Normally this is performed automatically during the render and need not be called explicitly.
Definition at line 433 of file character.cxx.
References NodePath::any_path(), ClockObject::get_frame_time, and ClockObject::get_global_clock().
Referenced by update_to_now().
◆ update_to_now()
| void Character::update_to_now | ( | ) |
Advances the character's frame to the current time, and then calls update().
This can be used by show code to force an update of the character's position to the current frame, regardless of whether the character is currently onscreen and animating.
This method is deprecated. Call update() instead.

References update().
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from PartBundleNode.
Definition at line 1108 of file character.cxx.
References Datagram::add_uint16(), and PartBundleNode::write_datagram().
◆ write_part_values()
| void Character::write_part_values | ( | std::ostream & | out | ) | const |
Writes a list of the Character's joints and sliders, along with each current position, in their hierchical structure, to the indicated output stream.
Definition at line 407 of file character.cxx.
◆ write_parts()
| void Character::write_parts | ( | std::ostream & | out | ) | const |
Writes a list of the Character's joints and sliders, in their hierchical structure, to the indicated output stream.
