Adding a lot of Avatars

[Roy]

Hi kennethkarthik,

Thank you, it works!
But I'm wondering any other way to add avatars.
In this program, 2 avatars are loaded 15 times, causing long time to run the program.
Any ideas?

Thanks

Hey Roy,

Vizard does it's optimisation when it reuses objects. However if you do want to improve load time, I would suggest just changing the state of your characters on the same avatar instead of adding a new one for each animation state. Check out the code below

import viz
import random
import viztask

avatar_files = ['vcc_male.cfg', 'vcc_female.cfg']#2avatars
animation = range(0,16)  #default 15 animations

viz.go()

piazza = viz.addChild('piazza.osgb')


#make 30 stimuli list (2 avatars x 15 animations), and shuffle the order
avatars = []
for i in avatar_files:
	avatarAnim = viz.addAvatar(i, pos=(0,0,0), euler=(180,0,0))
	avatarAnim.visible(viz.OFF)
	avatars.append(avatarAnim)
	
def experiment():
	yield viztask.waitKeyDown(viz.KEY_RETURN)
	for i in avatars:
		i.visible(viz.ON)
		for state in animation:
			yield viztask.waitTime(0.5)
			i.state(state)
			yield viztask.waitKeyDown(viz.KEY_RETURN)
		i.visible(viz.OFF)

viztask.schedule(experiment())
