Unhappy Avatar animation -- change states

Hi,

I want to change my avatar's states according to conditions. However, there are some problems with the codes:
Code:
def ani_change():
	female1 = viz.add('Avatars/Avatars/CC2_f001_hipoly_A1_v2.cfg')
	female1.setPosition(1,0.5,1)	
	female1.setEuler(90,8,0)
	bloNo = 10
	Code = [0,1,0,1,0,1,0,1,0,1]
	for block in range(bloNo):
		female1.visible(viz.ON)
		if Code[block] == 0:
			female1.execute(8,0,0,freeze =  True)
			female1.setAnimationSpeed(8,0)	
		elif Code[block] == 1:
			female1.execute(3,0,0, freeze = False)
			yield viztask.waitTime(3)
			for j in range(10):
				female1.blend(3,1-float(j/10))
				female1.blend(8,float(j/10))
				yield viztask.waitTime(float(j/2))
			yield viztask.waitTime(0.5)
			female1.state(8)
		female1.visible(viz.OFF)
		yield viztask.waitTime(5)

viztask.schedule(ani_change())
Here are the problems:
1) The avatar's states don't change;

2) The amplitude of the avatar's movement decrease across different trials. Eg. The highest point that her arm could reach is always lower than in the previous trial.

Many thanks!

I tested this code with the vcc_female avatar included with Vizard and it alternates between two animations. Does that work for you?

Hi,

Thank you for your reply! I tested the codes below:

Code:
def ani_change():
	female1 = viz.add('vcc_female.cfg')
	female1.setPosition(1,0,10)	
	female1.setEuler(90,8,0)
	bloNo = 10
	Code = [0,1,0,1,0,1,0,1,0,1]
	for block in range(bloNo):
		female1.visible(viz.ON)
		if Code[block] == 0:
			female1.execute(2,0,0,freeze =  True)
			female1.setAnimationSpeed(2,0)	
		elif Code[block] == 1:
			female1.execute(11,0,0, freeze = False)
			yield viztask.waitTime(3)
			for j in range(10):
				female1.blend(11,1-float(j/10))
				female1.blend(2,float(j/10))
				yield viztask.waitTime(float(j/2))
			yield viztask.waitTime(0.5)
			female1.state(2)
		female1.visible(viz.OFF)
		yield viztask.waitTime(5)

viztask.schedule(ani_change())
So what I expect in this case is that the female avatar stops then run for a while then stop again, which means she should switch between running and stop for five times. However, in this case she just runs then stops.

So how can I amend the codes to achieve my goal?

The example code below alternates between running and idle animations:

Code:
import viz
import viztask

viz.go()
viz.addChild('piazza.osgb')
female = viz.add('vcc_female.cfg',pos=[0,0,5],euler=[90,0,0])

def ani_change():
	
	for i in range(5):
		female.state(11)
		yield viztask.waitTime(3)
		female.state(1)
		yield viztask.waitTime(1)

viztask.schedule(ani_change())

Hi Jeff,

My initial goal in the first paragraph of codes is to let the avatar sit idle then frozen like a statue for a while. Then repeat this circle. Which is required by the experiment.

So is there a good way to solve this?

BTW, what could be the reason for the second problem?
