Detailed Description

This is the root of a MovingPart hierarchy.

It defines the hierarchy of moving parts that make up an animatable object.

Definition at line 46 of file partBundle.h.

Constructor & Destructor Documentation

◆ PartBundle()

PartBundle::PartBundle ( const std::string & name = "" )

explicit

Normally, a PartBundle constructor should not be called directly–it will get created when a PartBundleNode is created.

Definition at line 72 of file partBundle.cxx.

Member Function Documentation

◆ clear_anim_preload()

void PartBundle::clear_anim_preload ( )

inline

Removes any AnimPreloadTable associated with the PartBundle.

Definition at line 45 of file partBundle.I.

◆ clear_control_effects()

void PartBundle::clear_control_effects ( )

Sets the control effect of all AnimControls to zero (but does not "stop" the AnimControls).

The character will no longer be affected by any animation, and will return to its default pose (unless restore-initial-pose is false).

The AnimControls which are no longer associated will not be using any CPU cycles, but they may still be in the "playing" state; if they are later reassociated with the PartBundle they will resume at their current frame as if they'd been running all along.

Definition at line 197 of file partBundle.cxx.

◆ complete_pointers()

int PartBundle::complete_pointers	(	TypedWritable **	p_list,
		BamReader *	manager
	)

virtual

Takes in a vector of pointers to TypedWritable objects that correspond to all the requests for pointers that this object made to BamReader.

Reimplemented from PartGroup.

Definition at line 781 of file partBundle.cxx.

◆ control_activated()

void PartBundle::control_activated ( AnimControl * control )

virtual

Called by the AnimControl whenever it starts an animation.

This is just a hook so the bundle can do something, if necessary, before the animation starts.

Definition at line 533 of file partBundle.cxx.

◆ control_joint()

bool PartBundle::control_joint	(	const std::string &	joint_name,
		PandaNode *	node
	)

Specifies that the joint with the indicated name should be animated with the transform on the indicated node.

It will henceforth always follow the node's transform, regardless of any animations that may subsequently be bound to the joint.

Returns true if the joint is successfully controlled, or false if the named child is not a joint (or slider) or does not exist.

Definition at line 436 of file partBundle.cxx.

References PartGroup::apply_control(), and PartGroup::find_child().

◆ control_removed()

void PartBundle::control_removed ( AnimControl * control )

Called by the AnimControl when it destructs.

This needs to remove the AnimControl pointer from all pipeline stages.

◆ freeze_joint() [1/3]

bool PartBundle::freeze_joint	(	const std::string &	joint_name,
		const TransformState *	transform
	)

Specifies that the joint with the indicated name should be frozen with the specified transform.

It will henceforth always hold this fixed transform, regardless of any animations that may subsequently be bound to the joint.

Returns true if the joint is successfully frozen, or false if the named child is not a joint (or slider) or does not exist.

Definition at line 372 of file partBundle.cxx.

References PartGroup::apply_freeze(), and PartGroup::find_child().

◆ freeze_joint() [2/3]

bool PartBundle::freeze_joint	(	const std::string &	joint_name,
		const LVecBase3 &	pos,
		const LVecBase3 &	hpr,
		const LVecBase3 &	scale
	)

Specifies that the joint with the indicated name should be frozen with the specified transform.

It will henceforth always hold this fixed transform, regardless of any animations that may subsequently be bound to the joint.

Returns true if the joint is released, or false if the named child was not previously controlled or frozen, or it does not exist.

Definition at line 457 of file partBundle.cxx.

References PartGroup::clear_forced_channel(), and PartGroup::find_child().

◆ set_anim_preload()

void PartBundle::set_anim_preload ( AnimPreloadTable * table )

void PartBundle::set_control_effect	(	AnimControl *	control,
		PN_stdfloat	effect
	)

inline

Sets the amount by which the character is affected by the indicated AnimControl (and its associated animation).

Normally, this will only be zero or one. Zero indicates the animation does not affect the character, and one means it does.

If the _anim_blend_flag is not false (see set_anim_blend_flag()), it is possible to have multiple AnimControls in effect simultaneously. In this case, the effect is a weight that indicates the relative importance of each AnimControl to the final animation.

Definition at line 185 of file partBundle.I.

◆ set_update_delay()

void PartBundle::set_update_delay ( double delay )

inline

Specifies the minimum amount of time, in seconds, that should elapse between any two consecutive updates.

This is normally used by Character::set_lod_animation(), and should not be called directly.

Definition at line 208 of file partBundle.I.

◆ update()

bool PartBundle::update ( )

Updates all the parts in the bundle to reflect the data for the current frame (as set in each of the AnimControls).

Returns true if any part has changed as a result of this, or false otherwise.

Definition at line 477 of file partBundle.cxx.

References PartGroup::do_update(), ClockObject::get_frame_time, ClockObject::get_global_clock(), and AnimControl::mark_channels().

Member Data Documentation

◆ get_anim_blend_flag

bool PartBundle::get_anim_blend_flag

inline

Returns whether the character allows multiple different animations to be bound simultaneously.

See set_anim_blend_flag().

Definition at line 117 of file partBundle.h.

◆ get_blend_type

PartBundle::BlendType PartBundle::get_blend_type

inline

Returns the algorithm that is used when blending multiple frames or multiple animations together, when either anim_blend_flag or frame_blend_flag is set to true.

Definition at line 116 of file partBundle.h.

◆ get_frame_blend_flag

bool PartBundle::get_frame_blend_flag

inline

Returns whether the character interpolates (blends) between two sequential animation frames, or whether it holds the current frame until the next one is ready.

See set_frame_blend_flag().

Definition at line 118 of file partBundle.h.

◆ get_node

PartBundleNode * PartBundle::get_node

inline

Returns the nth PartBundleNode associated with this PartBundle.

Definition at line 114 of file partBundle.h.

◆ get_num_nodes

int PartBundle::get_num_nodes

inline

Returns the number of PartBundleNodes that contain a pointer to this PartBundle.

Definition at line 114 of file partBundle.h.

◆ get_root_xform

const LMatrix4 & PartBundle::get_root_xform

inline

Returns the transform matrix which is implicitly applied at the root of the animated hierarchy.

Definition at line 119 of file partBundle.h.

◆ set_anim_blend_flag

void PartBundle::set_anim_blend_flag

Defines the way the character responds to multiple calls to set_control_effect()).

By default, this flag is set false, which disallows multiple animations. When this flag is false, it is not necessary to explicitly set the control_effect when starting an animation; starting the animation will implicitly remove the control_effect from the previous animation and set it on the current one.

However, if this flag is set true, the control_effect must be explicitly set via set_control_effect() whenever an animation is to affect the character.

Definition at line 117 of file partBundle.h.

◆ set_blend_type

void PartBundle::set_blend_type

inline

Defines the algorithm that is used when blending multiple frames or multiple animations together, when either anim_blend_flag or frame_blend_flag is set to true.

See partBundle.h for a description of the meaning of each of the BlendType values.

Definition at line 116 of file partBundle.h.

◆ set_frame_blend_flag

void PartBundle::set_frame_blend_flag

inline

Specifies whether the character interpolates (blends) between two sequential frames of an active animation, showing a smooth intra-frame motion, or whether it holds each frame until the next frame is ready, showing precisely the specified animation.

When this value is false, the character holds each frame until the next is ready. When this is true, the character will interpolate between two consecutive frames of animation for each frame the animation is onscreen, according to the amount of time elapsed between the frames.

The default value of this flag is determined by the interpolate-frames Config.prc variable.

Use set_blend_type() to change the algorithm that the character uses to interpolate matrix positions.

Definition at line 118 of file partBundle.h.

◆ set_root_xform

void PartBundle::set_root_xform

inline

Specifies the transform matrix which is implicitly applied at the root of the animated hierarchy.

Definition at line 119 of file partBundle.h.
