[x3d-public] x3d-public Digest, Vol 173, Issue 32

[Andreas Plesch]

Apologies in advance for the lack of formatting,  the phone makes it hard.

Let me give it a try but there are many approaches.

If the goal is to have a run animation with a small jump at regular
intervals, the simple solution is to combine all interpolation data into a
single large interpolator and loop it. If that is not possible or
considered wasteful or not elegant enough, the task becomes chaining say 9
repeats of the run animation with one jump animation.

Given a design with a single TimeSensor, actually a solution without event
utilities may be preferable. I am thinking of an intermediate
ScalarInterpolator which chops up the timer fraction_changed into multiple
repeating fractions:

ScInter DEF 'repeater' key '0 0.1 0.1 0.2 0.2 0.3 .. 0.9 1' keyValue '0 0.5
0 0.5 0 0.5 .. 0.5 1'

The run and jump data would still be combined into a single Interpolator
which receives the value_changed and where the first half contains run data
for a single sequence and the second half jump data.

If it is not possible to have a single combined Interpolator, it is
necessary to have dedicated TimeSensors for each animation and perhaps use
event utilities.

Counted repeats of run could then be done in the same way with a repeater.
When the run time sensor ends, the stop time gets routed to the start time
of the jump timer.  When jump timer ends, the stop time gets routed to the
start time of the run timer. I think this is all what is needed, no event
utilities or scripts but testing will be necessary.

Cheers Andreas
