Question Spawn Avatar in front of User

Hi folks,

I have been trying to spawn an avatar model a few feet in front of the main view. I can get it to spawn at the location of the main view but not in front. I can offset the spawn location but not in relation to the viewpoint. Any help would be much appreciated.

Code:
def AddBot():
                x,y,z,d = viz.MainView.getAxisAngle()
                a,b,c = viz.MainView.getPosition()
                modelfile = randint(1,3)
                dudestate = randint(1, 14)
                if modelfile == 1:
                                dude = viz.add('vcc_male.cfg') 
                elif modelfile == 2:
                                dude = viz.add('vcc_male2.cfg') 
                elif modelfile == 3:
                                dude = viz.add('vcc_female.cfg') 
                dude.state(dudestate) 
                dude.setPosition(a + 5,b,c, viz.REL_LOCAL)
                dude.setAxisAngle(0,y,0,d)
                ColShape = Cloud.collideMesh()
                dude.collideCapsule()
vizact.onbuttondown(button_addbot, AddBot)

Here's an example, navigate around and you'll see a pigeon appear in front of the view every two seconds:

Code:
import viz
import vizact
viz.go()

viz.addChild('piazza.osgb')

avatar = viz.addAvatar('pigeon.cfg',pos=[0,0,6],euler=[180,0,0],scale=[4,4,4])
avatar.state(1)

def spawnAvatar():
	
	pos = viz.MainView.getPosition()
	yaw = viz.MainView.getEuler()[0]
	vector = viz.MainView.getMatrix().getForward()
	amount = 5
	x,y,z = vizmat.MoveAlongVector(pos,vector,amount)
	a = avatar.clone(pos=[x,0,z],euler=[yaw-180,0,0],scale=[4,4,4])
	
vizact.ontimer(2,spawnAvatar)

You can use the player.transform.forward direction to get the players direction as a vector and transform.rotation to get the orientation. You can also do math operations of vectors which makes things so much better than modifying the components.
