#include <u_play_list.h>

Inheritance diagram for NL3D::UPlayList:

NL3D::CPlayListUser

Detailed Description

A playlist/channelmixer, from which you setup your mix of animations (blend, skeleton template weight...). Once this UPlayList is created from the UPlayListManager (with an UAnimationSet), you just need to registerTransform() your object(s) (eg: an UInstance). Then you can use all the Animation setup function to blend, mix, setup time etc...

NB: a playlist is actually played through UPlayListManager::animate(). NB: all AnimationTime are in second.
