WorldViz User Forum - removing clones

Dear users,

I'm running an experiment in which 2/3 trial require poles to be places in the scene, and one trial requires these to be removed.

Early on in my script I use

Code:

def addcones():

        global cone

        ###########code for placing cones

        for place in (positionlistA,positionlistB,positionlistC,positionlistD,positionlistE):

                pos = (place)

                cone = viz.add('pole.wrl',cache=viz.CACHE_CLONE,pos=pos)

                cone.color(0,1,0)

                cone.setScale(2,0.05,2)

#cones.append(cone)

                if place[3] >0:

                        cone.setPosition(1,0,0,viz.REL_LOCAL) 

                if place[3] <0:

                        cone.setPosition(-1,0,0,viz.REL_LOCAL)

to add the cones and in my trial selection function I use the same code but just remove the cones from the scene.

Code:



if trialtype ==0:

                        viz.MainScene.visible(viz.OFF,viz.WORLD)

                        yield viztask.waitTime(5)

                        trial.message('Heading')

                        yield viztask.waitTime(5)

                        trial.remove()

                        createpath()

                        cone.remove()

                        passiveheading()

                        yield viztask.waitTime(0.5)

                        viz.MainScene.visible(viz.ON,viz.WORLD)

                        yield viztask.waitTime(16.9)

to remove the cones before running the trial. However, it only removes one cone. My understanding is that clones should copy the original? Is this not the case?

I'd appreciate any pointers on this. Many Thanks in advance.
