AnimControl¶

class AnimControl

Controls the timing of a character animation. An AnimControl object is created for each character/bundle binding and manages the state of the animation: whether started, stopped, or looping, and the current frame number and play rate.

AnimBundle *get_anim(void) const

Returns the AnimBundle bound in with this AnimControl.

PandaNode *get_anim_model(void) const

Retrieves the pointer set via set_anim_model(). See set_anim_model().

BitArray const &get_bound_joints(void) const

Returns the subset of joints controlled by this AnimControl. Most of the time, this will be BitArray::all_on(), for a normal full-body animation. For a subset animation, however, this will be just a subset of those bits, corresponding to the set of joints and sliders actually bound (as enumerated by bind_hierarchy() in depth-first LIFO order).

int get_channel_index(void) const

Returns the particular channel index associated with this AnimControl. This channel index is the slot on which each AnimGroup is bound to its associated PartGroup, for each joint in the animation.

It will be true that get_part()->find_child(“n”)->get_bound(get_channel_index()) == get_anim()->find_child(“n”), for each joint “n”.

static TypeHandle get_class_type(void)
PartBundle *get_part(void) const

Returns the PartBundle bound in with this AnimControl.

std::string get_pending_done_event(void) const

Returns the event name that will be thrown when the AnimControl is finished binding asynchronously.

bool has_anim(void) const

Returns true if the AnimControl was successfully loaded, or false if there was a problem. This may return false while is_pending() is true.

bool is_pending(void) const

Returns true if the AnimControl is being bound asynchronously, and has not yet finished. If this is true, the AnimControl’s interface is still available and will be perfectly useful (though get_anim() might return NULL), but nothing visible will happen immediately.

virtual void output(std::ostream &out) const
void set_anim_model(PandaNode *model)

Associates the indicated PandaNode with the AnimControl. By convention, this node represents the root node of the model file that corresponds to this AnimControl’s animation file, though nothing in this code makes this assumption or indeed does anything with this node.

The purpose of this is simply to allow the AnimControl to keep a reference count on the ModelRoot node that generated it, so that the model will not disappear from the model pool until it is no longer referenced.

void set_pending_done_event(std::string const &done_event)

Specifies an event name that will be thrown when the AnimControl is finished binding asynchronously. If the AnimControl has already finished binding, the event will be thrown immediately.

void wait_pending(void)

Blocks the current thread until the AnimControl has finished loading and is fully bound.
