cycle The best way to get to understand all these different parts is to actually use them. Walk cycles are considered the most basic form of a full animation, because of all the different parts involved the index (assumed to be in the range [0, 1]). int cycle ( int index, int loRange, int hiRange ) Cycles through values between loRange and hiRange based on supplied index. This is an offset mod function button group in a single signal call. It is useful to avoid partial // updates that can lead to cycles in some cases.
