Definition at line 58 of file partBundle.I.

void PartBundle::clear_control_effects ( ) [inherited]

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.

bool TypedWritable::decode_raw_from_bam_stream ( TypedWritable *&  ptr,
ReferenceCount *&  ref_ptr,
const string &  data,
BamReader reader = NULL 
) [static, inherited]

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.

void PartGroup::find_bound_joints ( int &  joint_index,
bool  is_included,
BitArray bound_joints,
const PartSubset subset 
) [protected, virtual, inherited]

Similar to bind_hierarchy, but does not actually perform any binding.

All it does is compute the BitArray bount_joints according to the specified subset. This is useful in preparation for asynchronous binding--in this case, we may need to know bound_joints immediately, without having to wait for the animation itself to load and bind.

void ReferenceCount::local_object ( ) [inline, inherited]

This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.

This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void PartBundle::set_anim_blend_flag ( bool  anim_blend_flag) [inherited]

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.

void PartBundle::set_control_effect ( AnimControl control,
float  effect 
) [inline, inherited]

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.

void PartBundle::set_frame_blend_flag ( bool  frame_blend_flag) [inline, inherited]

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.

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.
