# MovingPartBase¶

class MovingPartBase

Bases: PartGroup

This is the base class for a single animatable piece that may be bound to one channel (or more, if blending is in effect). It corresponds to, for instance, a single joint or slider of a character.

MovingPartBase does not have a particular value type. See the derived template class, MovingPart, for this.

AnimChannelBase *get_bound(int n) const

Returns the nth bound channel on this PartGroup. n can be determined by iterating from 0 to one less than get_max_bound(); or n might be AnimControl::get_channel_index().

This will return NULL if there is no channel bound on the indicated index. It is an error to call this if n is less than zero or greater than or equal to get_max_bound().

static TypeHandle get_class_type(void)
int get_max_bound(void) const

Returns the number of channels that might be bound to this PartGroup. This might not be the actual number of channels, since there might be holes in the list; it is one more than the index number of the highest bound channel. Thus, it is called get_max_bound() instead of get_num_bound().
