default.player_register_model(name, def)
^ Register a new model to be used by players.
^ <name> is the model filename such as "character.x", "foo.b3d", etc.
^ See Model Definition below for format of <def>.
default.registered_player_models[name]
^ See Model Definition below for format.
default.player_set_model(player, model_name)
^ <player> is a PlayerRef.
^ <model_name> is a model registered with player_register_model.
default.player_set_animation(player, anim_name [, speed])
^ <player> is a PlayerRef.
^ <anim_name> is the name of the animation.
^ <speed> is in frames per second. If nil, default from the model is used
default.player_set_textures(player, textures)
^ <player> is a PlayerRef.
^ <textures> is an array of textures
^ If <textures> is nil, the default textures from the model def are used
default.player_get_animation(player)
^ <player> is a PlayerRef.
^ Returns a table containing fields "model", "textures" and "animation".
^ Any of the fields of the returned table may be nil.
