Packages
Assign a Character package to an Actor when it needs a Character model and movement. Not every Actor needs a Character package. The package supplies the available model and animations. A script chooses how the Character acts.
Movement
Worldkiln handles gravity and collision. Scripts can set movement intent, facing, and animation. Use the Actor API for authored Actors and the Entity API for live Entities.
Attach objects
Attach an Actor or Entity to a named rig point with attach(). Both point names must exist. Use detach() to restore normal movement and physics.
See the attachment calls.
Animation layers
An Entity's animation handle can play a clip over part of a rig. See play_layer.
