WorldViz User Forum - Hotspots and Video

Hello,

I don't know if it's a bug but just using viz.addVideo in a world screws up the hotspots. The hotspot code below is a working mix from two other posts and I added the two commented blocks. Uncomment each one and see for yourself.

Code:

import viz

viz.go()



viz.add('tut_ground.wrl')



#Declare Radius of hotspot

RADIUS = 1



#Declare position of hotspot

HOTSPOT_X = 0

HOTSPOT_Z = 3



class HotspotClass(viz.EventClass):

        def __init__(self,enter,leave):

                viz.EventClass.__init__(self)

                

                self.enter = enter

                self.leave = leave

                

                #Create a hotspot that will be triggered when we enter the circle

                viz.starthotspot(self.enter,viz.CIRCLE_HOTSPOT_IN,HOTSPOT_X,HOTSPOT_Z,RADIUS)

                

                self.callback(viz.HOTSPOT_EVENT,self.onhotspot)

                

        def onhotspot(self,id,x,y,z):

                if id == self.enter:

                        print 'Entered hotspot',self.enter

                        #Create a hotspot that will be triggered when we leave the circle

                        viz.starthotspot(self.leave,viz.CIRCLE_HOTSPOT_OUT,HOTSPOT_X,HOTSPOT_Z,RADIUS)

                elif id == self.leave:

                        print 'Leaving hotspot',self.leave

                        #Create a hotspot that will be triggered when we enter the circle

                        viz.starthotspot(self.enter,viz.CIRCLE_HOTSPOT_IN,HOTSPOT_X,HOTSPOT_Z,RADIUS)



import math

viz.startlayer(viz.LINES)

viz.linewidth(3)

viz.vertexcolor(viz.RED)

viz.vertex(HOTSPOT_X,0,HOTSPOT_Z)

viz.vertex(HOTSPOT_X,2,HOTSPOT_Z)

viz.startlayer(viz.LINE_LOOP)

for a in range(0,360,10):

        x = math.sin(viz.radians(a))*RADIUS

        z = math.cos(viz.radians(a))*RADIUS

        viz.vertex(x+HOTSPOT_X,0.1,z+HOTSPOT_Z)

viz.endlayer()



# uncomment here and:

# enter activates at the beginning

# leave activates at your first move (anywhere)

#viz.addVideo('mona.mpg')



HotspotClass(0,1)

HotspotClass(2,3)



# uncomment here and:

# both enter and leave activate when you enter the hotspot

# but never again

#viz.addVideo('mona.mpg')
