animation pausing problem

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

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.

#viz.collision(viz.ON)



view = viz.get(viz.MAIN_VIEWPOINT)

view.rotate(0,1,0,90)

viz.MainView.collision(viz.ON)





#This function is called when a collision occurs

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,
Masaki

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.

Code:

import viz

import math

import vizmat

import vizinfo

import vizact

viz.go()







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

street = viz.add('tut_ground.wrl')

street.translate(0,-.2,0)







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.

car = viz.add('mini.osgx')



#set car stuff

car.translate(-1.5,0,8)

car.rotate(0,1,0,180)



















#Set up for timing.

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

Code:

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.
