Avatar and Vizinfo InfoPanel one after other

[Vishav]

Dear all,

I want my avatar to appear and ask give some information and after avatar finish his speech then textbox with questions appears? In my code they appear parallely. How to make this possible. My code is:

b1=vizfx.addChild('balloon.osgb',pos=(0,0,0),euler =(0,0,0),scale=(50,50,50))
infoBox = vizinfo.InfoPanel('What is the color of balloon?')

Thanks
