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.

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.
