Detailed Description

This is the base class for AnimChannel and AnimBundle.

It implements a hierarchy of AnimChannels. The root of the hierarchy must be an AnimBundle.

Member Function Documentation

◆ __init__() [1/2]

__init__ ( AnimGroup  parent,
str  name 
)

Creates the AnimGroup, and adds it to the indicated parent.

The only way to delete it subsequently is to delete the entire hierarchy.

◆ __init__() [2/2]

__init__ ( const  AnimGroup)

◆ findChild()

AnimGroup findChild ( str  name)

Returns the first descendant found with the indicated name, or NULL if no such descendant exists.

This method searches the entire graph beginning at this AnimGroup; see also get_child_named().

◆ getChild()

AnimGroup getChild ( int  n)

Returns the nth child of the group.

◆ getChildNamed()

AnimGroup getChildNamed ( str  name)

Returns the first child found with the indicated name, or NULL if no such child exists.

This method searches only the children of this particular AnimGroup; it does not recursively search the entire graph. See also find_child().

◆ getChildren()

list getChildren ( )

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getNumChildren()

int getNumChildren ( )

Returns the number of child nodes of the group.

◆ output()

output ( Ostream  out)

Writes a one-line description of the group.

◆ sortDescendants()

sortDescendants ( )

Sorts the children nodes at each level of the hierarchy into alphabetical order.

This should be done after creating the hierarchy, to guarantee that the correct names will match up together when the AnimBundle is later bound to a PlayerRoot.

◆ write()

write ( Ostream  out,
int  indent_level 
)

Writes a brief description of the group and all of its descendants.
