Avatar eye contact with user as it moves
I am looking at the sample WatchNode code. I removed the ball code and changed the nodeToLookAt in line 74 to viz.MainView. I also changed the avatar's state to (1). This makes the avatar's head follow me as I move around, which is the first thing I want. However, I seem to keep failing when I try to then make the avatar move/walkTo somewhere while still looking at me. I am missing something small here but that's b/c I am a newbie I am sure. Thanks for the help.
Code:
import viz
import vizact
viz.setMultiSample(8)
viz.fov(60)
viz.go(viz.FULLSCREEN)
class WatchNodeAction(viz.ActionClass):
"""Makes avatar head follow node object around"""
def begin(self,object):
"""Called once when action starts"""
#Get the node the avatar should look at
self.nodeToLookAt = self._actiondata_.data[0]
#Get time the avatar will look at object
self.duration = self._actiondata_.data[1]
self.headBone = self._actiondata_.data[2]
self.blendIn = self._actiondata_.data[3]
self.timeElapsed = 0
#Get the head bone and lock it
self.head = object.getbone(self.headBone)
self.head.lock()
self.startQuat = self.head.getQuat()
def update(self,elapsed,object):
"""Called every frame to update action"""
self.timeElapsed += elapsed #time avatar has looked at node
p = self.timeElapsed / self.blendIn
#If looking for a finite duration, check if time has passed
if self.duration > 0.0 and self.timeElapsed > self.duration:
#duration passed, end action
self.head.lookAt( self.nodeToLookAt.getPosition(), 0, viz.AVATAR_WORLD )
self.end(object) #End the action and clear it from the action queue
elif p < 1.0:
#blend in head look
self.head.lookAt( self.nodeToLookAt.getPosition(), 0, viz.AVATAR_WORLD )
targetQuat = self.head.getQuat()
nextQuad = vizmat.slerp(self.startQuat,targetQuat,p)
self.head.setQuat(nextQuad)
else:
#Done with blend in, just look at node
self.head.lookAt(self.nodeToLookAt.getPosition(), 0, viz.AVATAR_WORLD)
def end(self,object):
if self.head:
self.head.unlock()
viz.ActionClass.end(self,object)
#Function to construct the action instance
def watchNode( nodeToLookAt, duration = viz.FOREVER, headBone = 'Bip01 Head', blendIn = .2 ):
action = viz.ActionData()
action.data = [ nodeToLookAt, duration, headBone, blendIn ]
action.actionclass = WatchNodeAction
return action
viz.MainView.setPosition( 0, 0, 0 )
male = viz.add( 'vcc_male.cfg' )
male.setPosition( 0, -1.5, 2 )
male.setEuler( 180, 0, 0 )
male.state(1)
#Apply the action to the avatar
male.addAction( watchNode(viz.MainView, viz.FOREVER) )
def endHeadWatch():
#blend head to neutral orientation
head = male.getBone('Bip01 Head')
headQuat = head.getQuat(viz.AVATAR_LOCAL)
male.endAction()
head.lock()
head.setQuat(headQuat, viz.AVATAR_LOCAL)
male.addAction( vizact.headto( 0,0,0, 20, bone = 'Bip01 Head'), 1 )
vizact.onkeydown(' ',endHeadWatch)
