Switches & Sequences


A pfSwitch allows the selection of one, none, or all of its child nodes for drawing.
To select a single child, val should be the number of that child (in the range 0 to numchildren-1). val=PFSWITCH_ON selects all the children; val=PFSWITCH_OFF deselects all the children. Only the selected children will be traversed during subsequent database traversals.


A pfSequence automatically cycles through a range of children, displaying each one for a given length of time. The setTime method sets how long a given frame (child node) will be displayed. setInterval and setDuration can be used to alter various sequencing options, such as speed and cycling method. setMode starts and stops the sequence.
