Multidimensional Arrays

[farshizzo]

Hi,

If you are only viewing each avatar one at a time, then you only need to add 3 avatars. When you are starting an avatar link the appropriate object to it. When you are done with the avatar unlink the object from it.

The only problem with that is that I would need more than 3 avatars to come out at once. The experimenter wants a continous flow of avatars. Would I be able to do this w/only an array of 3 avatars and the link and unlink?

Hi,

You need to create at least the same number of avatars that you want to be visible at the same time. So if you only need 6 avatars to be visible at a time, then you need at least 6 avatars.

Thanks that helped a lot. I have the program functioning as I wanted it to. My next step is to "tag each avatar". When I call the avatars using:

#Create all the avatars and add them to the waiting list
for x in range(0,3):
 if x == 0:
  male = viz.add(people[0]) 
  male.scale(.1,.1,.1)
  link = viz.add(viz.GROUP) 
  myphone = link.add(objects[0])
  myphone.scale(.0005,.0005,.0005)
  male.linkbone(link,'skel_HandR')
 elif x == 1:
  male = viz.add(people[1])
  link = viz.add(viz.GROUP) 
  myphone = link.add(objects[1])
  myphone.scale(.0005,.0005,.0005)
  myphone.translate(0,-.25,.17)
  myphone.rotate(180)
  male.linkbone(link,'skel_Neck')
 elif x ==2:
  male = viz.add(people[2])
  link = viz.add(viz.GROUP) 
  myphone = link.add(objects[2])
  myphone.scale(.0008,.0008,.0008)
  myphone.rotate(66.51,151.49,86.01)
  myphone.translate(-0.02,0.04,0.02)
  male.linkbone(link,'skel_HandRF')
 male.translate(3*x,-10,10)
 male.rotate(180)
 #Add the avatar to the waiting and lemming list
 waitlist.append(male)
 characters.append(male)

Once they get shot they go through a RemoveAvatar function and a RestoreAvatar function as shown below:

def RestoreAvatar():
 global keyindex
 if len(dead_list):
  print "avatar restored"
  avatar = waitlist.pop() #Ressurrect dead avatar
  avatar.visible(1) #Make it visible
  characters.append(avatar) #Add it to avatar list
 # walkAvatar(avatar)
 print 'avatar restored'
def RemoveAvatar(avatar):
 avatar.visible(0) #Hide avatar
 #avatar._face_.visible(0) #Hide face
 avatar.speed(1) #Restore speed
 characters.remove(avatar) #Remove from list
 dead_list.append(avatar) #Add to dead list

There are a couple things I have to do that I'm not sure how to do. First of all, I have to say which avatar (e.g. avatar 1 with object 1, avatar 1 w/object 2...etc.) I was thinking of having a variable that increments whenever each avatar gets shot, however the problem I'm having is I don't know how to have the program tell which avatar got shot. Once they get shot, I have to unlink their object and link them back to another object for the next time they appear. FYI here is the code for what happens when they get shot:

 if info.intersected:
  autospawn = not autospawn
  print 'intersect point is',info.intersectPoint
  if info.object in waitlist:
   print "in waitlist"
  if info.object in dead_list:
   print "in dead_list"
  if info.object in characters:
   print "in characters"
   avatarsHit = avatarsHit + 1
   viz.playsound('arrgh.wav')
   print 'Avatars hit: ', avatarsHit
   WaitThenFreeze = vizact.sequence( vizact.waittime(info.object.getduration(7)+.001), vizact.speed_node(0) )
   info.object.execute(7)
   info.object.clear(viz.ALL)
   info.object.clear(viz.CURRENT_ACTION)
   info.object.add(WaitThenFreeze) #Add the action to the avatar
   RemoveAvatarAction = vizact.call(RemoveAvatar,info.object)
   info.object.add(RemoveAvatarAction) #Add action to remove avatar

Please help

Hi,

I'm not sure exactly what you are asking here. You just need a way to identify each avatar when they get shot? Just add some tag to each avatar when you create/restore it.

male.tag = 'avatar 1 with object 2'

Then when they get shot just look up the tag:

print info.object.tag,'got shot'

PERFECT! Thanks for the help. Can I do the same thing with the object they are holding? Since the object is a different array that's merely linked to this one, how do I identify the object in hand? Basically if it's a gun or a cell phone I just need to specify that it's "non-threatening". If it's a gun then i have to specify that it's "threatening".

Thanks again!

Hi,

In python, you can add as many attributes to an object as you wish. So to determine if an object is "threatening" simply give it an attribute which says so.

donut = viz.add('donut.wrl')
donut.isThreatening = False
donut.isDelicious = True

gun = viz.add('gun.wrl')
gun.isThreatening = True
gun.isDelicious = False
