mainview

I am trying to make the mainview to keep its moving with the avatar’s moving and speeds as well, I tried with the following simple code.

Code:

import viz





viz.go()

# add room

room = viz.add('court.ive')



# add subject

female= viz.add('vcc_female.cfg')

female.setPosition([0,0,0])

female.state(2)

walk=vizact.move(0,0,5,5)

female.addAction(walk)

viz.MainView.getPosition(female.getPosition())

print female.getPosition

But does not working

Code:

viz.MainView.getPosition(female.getPosition())

You're invoking the wrong function for a start, you need to call 'viz.MainView.setPosition' not 'viz.MainView.getPosition'.

This will only occur once though, you'll need a timer callback function to constantly acquire the position of the avatar and assign it to the main view position.

Something like:

Code:

def myTimer(num):

      newPosition = female.getPosition()

      offset = [0,0,5] # Maybe add an offset so the camera isn't directly ontop of the avatar to keep it in view?

      viz.MainView.setPosition(newPosition+offset)



viz.callback(viz.TIMER_EVENT,myTimer) # Pass callback

viz.starttimer(0,0.5,viz.FOREVER) # Start the timer

Sorry, that above callback won't work right...try this:

Code:

def myTimer(num):

    newPosition = female.getPosition()

    newPosition[2] = newPosition[2]-2     # Move back in Z a bit

    newPosition[1] = newPosition[1]+1.5 # Move up in Y a bit

    viz.MainView.setPosition(newPosition)

    print female.getPosition()

Also alter the 'viz.starttimer(0,0.5,viz.FOREVER)' to 'viz.starttimer(0,0.05,viz.FOREVER)' for a smoother motion.

you can also try linking the viewpoint to the avatar. This following lines create a link and then creates an offset so the view is behind the avatar

Code:

view = viz.MainView

link = viz.link(female, view)

link.preTrans([0,0,-1])
