add info on avatar

[xcuddlex]

info = vizinfo.add( 'WELCOME.' )
info.translate( .98, .3 )

i think this is how to add info onto the screen
but how can i add this kind of info on specific avatar?
for example i have three avatar
i want to add different info on each avatar when i flash the marker to the webcam.

You can create a separate info box for each avatar. When a marker is in view change the visibility of the info box:

info = vizinfo.add('avatar')
info.visible(viz.OFF)

def updateInfo():
	if marker.getVisible():
		info.visible(viz.ON)
	else:
		info.visible(viz.OFF)
		
vizact.ontimer(0,updateInfo)

jeff,
how can i do multiple if statements for the three different avatar ?

[Jeff]

You could have multiple if/else statements one after the other in the timer function.

Or you could keep your markers, models, info boxes in lists and place a loop in the timer function. For each iteration of the loop you can check the visibility of a marker and set the visibility of the related info box. The following example would do that for 3 matrix markers, ids 1,2,3:

import viz
import vizact
import vizinfo

viz.go()

MARKER_IDS = [1,2,3]
AVATAR_FILES = ['vcc_male.cfg','vcc_female.cfg','duck.cfg']
INFO_POSITIONS = [[0.2,0.8],[0.2,0.6],[0.2,0.4]]
INFO_MESSAGES = ['male','female','duck']

marker_list = []
avatar_list = []
info_list = []

#Add ARToolkit extension
ar = viz.add('artoolkit.dle')

#Create camera using first available webcam
camera = ar.addWebCamera()

for i in range(len(MARKER_IDS)):
	
	marker = camera.addMatrixMarker(MARKER_IDS[i],width=1000)
	avatar = viz.addAvatar(AVATAR_FILES[i])
	avatar.visible(viz.OFF)
	viz.link(marker,avatar)
		
	info = vizinfo.add(INFO_MESSAGES[i])
	info.visible(viz.OFF)
	info.translate(INFO_POSITIONS[i])
	
	marker_list.append(marker)
	avatar_list.append(avatar)
	info_list.append(info)
	
	
def updateVisible():
	for i in range(len(MARKER_IDS)):
		if marker_list[i].getVisible():
			info_list[i].visible(viz.ON)
			avatar_list[i].visible(viz.ON)
		else:
			info_list[i].visible(viz.OFF)
			avatar_list[i].visible(viz.OFF)
	
vizact.ontimer(0,updateVisible)
