animation pausing problem

[just alex]

Hi,
I've got a program where a bunch of avatars are supposed to be walking around a city doing mundane things (window shopping, talking with someone, etc.)
My problem is that the avatars that I have just walking around the city block pause any time they reach a checkpoint in their animation path and they go back to their default state for a moment until they start walking again. I've tried a few tricks to get them to smooth out, but I can't figure out how to get them to just walk around. Here's the relevant code

males = []
females = []
walking = []
whichturn = 0

#List the timers.
WALKING = 0
for i in range(2):
	male = viz.add('male.cfg')
	male.translate(i,0,0)
	male.visible(0,'male_head.cmx')
	male.face(maleheads[i])
	clothes = viz.add(maleclothes[i])
	for j in bodyparts:
		male.texture(clothes,j)
	males.append(male)
		
for i in range(2):
	female = viz.add('female.cfg')
	female.translate(i,0,0)
	females.append(female)
#Set up paramters for walking guy.
males[0].translate(0,0,-5)
males[0].rotate(0,1,0,-90)
males[0].whichturn = 0
males[0].set = [[1.5,0,-5],[1.5,0,15],[5,0,15],[-5,0,-5]]
males[0].end = 4
walking.append(males[0])

#Set up paramters for walking girl.
females[0].translate(1,0,-7)
females[0].rotate(0,1,0,-90)
females[0].whichturn = 0
females[0].set = [[1.5,0,0],[1,0,15],[2,0,15],[-5,0,-5]]
females[0].end = 3
walking.append(females[0])
def onkeydown(key):
	if key == '0':
		viz.starttimer(WALKING, .1, viz.PERPETUAL)
def ontimer(num):
	global gravity, timebomb
	
	if num == DRIVING:
		for agent in driving:
			path.play()
	if num == WALKING:
		for agent in walking:
			agentposition = agent.get(viz.POSITION)
			agentgap = vizmat.Distance(agentposition, agent.set[agent.whichturn])
			if agentgap < .1:
				agent.whichturn += 1
				if agent.whichturn == agent.end:
					agent.whichturn = 0
			
			walk = vizact.walkto(agent.set[agent.whichturn][0],agent.set[agent.whichturn][1],agent.set[agent.whichturn][2])
			agent.addAction(walk)

Please post an example that reproduces the issue and I can run without having to alter the code.

The viztask module may be helpful to control your program flow if you have the avatars doing one thing after another.

There's a few left over bits from previous experiments in here, but I don't think anything left in there affects the walking around

This is still not a working script. Please cut it down to *just* what produces the error and please make sure that it runs without errors.

Thanks,

Sorry, i had a case of the dumb and posted an old code I was messing with. This should all be with general stuff so you shouldn't need to make any alterations. All I really need is for the avatars to walk around continuously to create a little veracity in my city.

#Add the street and drop it a little bit to be below the avatars feet.

females = []
walking = []
whichturn = 0

#List the timers.
WALKING = 0

HOLDVIEW = 8
TIMING = 9



for i in range(1):
	female = viz.add('vcc_female.cfg')
	female.translate(i,0,0)
	females.append(female)




#Set up paramters for walking girl.
females[0].translate(1,0,-7)
females[0].rotate(0,1,0,-90)
females[0].whichturn = 0
females[0].set = [[1.5,0,0],[1,0,15],[2,0,15],[-5,0,-5]]
females[0].end = 3
walking.append(females[0])

#Add car.

	if key == '0':

		for agent in walking:

			agentgap = vizmat.Distance(agentposition, agent.set[agent.whichturn])
			if agentgap < .1:
				agent.whichturn += 1
				if agent.whichturn == agent.end:
					agent.whichturn = 0
			
			walk = vizact.walkto(agent.set[agent.whichturn][0],agent.set[agent.whichturn][1],agent.set[agent.whichturn][2])

Hi,

I rewrote your code using the viztask module. I left sample code for you in the task function to wait for a key press or a certain length of time to pass before continuing on. You might want to look into using the viztask module instead of timers - samples are in the help doc.

Best,
Masaki

import viztask

def myTask():
	# wait for a certain length of time or a key press
	waittime = viztask.waitTime( 1 )	#define wait one second
	waitkey =viztask.waitKeyDown('0')	#define wait for 0 key press
	yield viztask.waitAny( [waittime, waitkey] )	# #wait for either waittime or waitkley
	while True: #while loop infinitely
		for agent in walking:
			agentposition = agent.get(viz.POSITION)
			agentgap = vizmat.Distance(agentposition, agent.set[agent.whichturn])
			if agentgap < .1:
				agent.whichturn += 1
				if agent.whichturn == agent.end:
					agent.whichturn = 0
			
			walk = vizact.walkto(agent.set[agent.whichturn][0],agent.set[agent.whichturn][1],agent.set[agent.whichturn][2])
			agent.addAction(walk)
			
			yield viztask.waitActionEnd( agent, walk )	#wait for walk action to end for agent
			print 'walk to', agent.whichturn, 'done' 
			yield viztask.waitTime(5) 	#wait 5 seconds before looping again
			
viztask.schedule( myTask() )

Thanks much. When I was taught how to do this animation, I was taught to use timers, so I never really learned how to used viztask. It strikes me as a heck of a lot easier than using timers.
