Creating Subclasses of Vizard Classes

[farshizzo]

Hi,

If you wanted to create something that is easy to use and reusable then I would suggest creating your own vizact Action. Here is a basic template for creating the action:

class MyHeadAction(viz.ActionClass):

	def begin(self,object):
		#Get the list of ori data
		self.oridata = self._actiondata_.data
		
		#Get the head bone and lock it
		self.bone = object.getbone('skel_Head')
		self.bone.lock()

	def update(self,elapsed,object):
		#Called every frame to update action
		if self.finished():
			return

		#Update the head rotation
		self.bone.rotate(x,y,z)
		
		#When the action is finished call the following
		self.end(object)
		
def animatehead(filename):
	action = viz.ActionData()
	#Read orientation data from file and add it to action data
	action.data.append([x,y,z])
	action.actionclass = MyHeadAction
	return action

Now you would use the following code to perform your custom action:

headAction = animatehead('headdata.txt')

avatar.add(headAction)

Let me know if you need anymore help with this
