double Cycle (object master, channel masterChan, object slave, channel slaveChan, double animLength)

Return Value: 1.0 = success, 0.0 = failure.

Arguments:

Drives the motion of [slave:slaveChan] based on the value of [master:masterChan] .[slave:slaveChan] must already have animation on it, the first key on the channel defines the start of the cycle, the end if determined by adding animLength to the first keyframe. The motion of [slave:slaveChan] is replaced with the result of this function. When masterChan = 0.0 the value of slaveChan will be the same as the value of it's first keyframe. When masterChan = 1.0 the value of slaveChan will be the same as the value of the curve at first keyframe + animLength.

Example:

Exp_1
|_ Cycle(Slider, xpos, Null_1, motion, 60)

Exp_1
|_ Cycle(Slider, xpos, Null_1, motion, 60)

As Slider's xpos is moved from 0.0 to 1.0 the motion of Null_1 will change from the values of it's first keyframe to the values at first keyframe + 60.

Note: See Tutorials->Expressions->Cycle for an example of Cycle in action.
