Temporal delay on movement

[Jeff]

You could try something like the following:

import viz
import vizact
import vizcam

viz.go()

DELAY = 2
dojo = viz.add('dojo.osgb')
walkNav = vizcam.addWalkNavigate()

recordedData = []
def RecordTrackingData():
	recordedData.append( (walkNav.getPosition(), walkNav.getQuat()) )
vizact.onupdate(0,RecordTrackingData)

def ApplyTrackingData():
	pos,ori = recordedData.pop(0)
	viz.MainView.setPosition([pos[0],1.8,pos[2]])
	viz.MainView.setQuat(ori)
	
ApplyDataCallback = vizact.onupdate(0,ApplyTrackingData)
ApplyDataCallback.setEnabled(viz.OFF)

vizact.ontimer2(DELAY,0,ApplyDataCallback.setEnabled,viz.ON)

Fantastic! That worked for using addWalkNavigate, but I'm now using VRPN 7 to get location data, as such:

vrpn = viz.add('vrpn7.dle')
headPos = vrpn.addTracker( 'PPT0@'+PPT_MACHINE,0)
iLabs = viz.addExtension( 'inertiallabs.dle' )
headOri = iLabs.addSensorBus(port=INERTIALLABS_HEAD_PORT)[0]

I've tried subbing these values into the code that worked previously, but it's seeming that won't be possible. How should I go about implementing the same idea using vrpn?
