If you have your
exampleObject class inherit from the Vizard node class, then your class instance will be returned from the pick command. I modified your example to show this:
Code:
import viz
import vizact
#Sample Environment
ground = viz.add('tut_ground.wrl')
ground.tag = "You missed clicking on a box."
class exampleObject(viz.VizNode): #Example class containing a mesh
def __init__(self,classTag,geometryTag,x,y,z,color):
model = viz.add('box.wrl')
viz.VizNode.__init__(self,model.id)
self.class_tag = classTag
self.geometry_tag = geometryTag
self.setPosition(x,y,z)
self.color(color)
self.setScale(.333,.333,.333)
def printTag(self):
print self.class_tag,self.geometry_tag
#Creating some objects
A = exampleObject("classA","geometryA",-.5,1.6,2,viz.RED)
B = exampleObject("classB","geometryB",0,1.6,2,viz.BLUE)
C = exampleObject("classC","geometryC",.5,1.6,2,viz.GREEN)
def clickPick(): #Pick an object
mesh = viz.pick()
if isinstance(mesh,exampleObject):
mesh.printTag()
vizact.onmousedown(viz.MOUSEBUTTON_LEFT, clickPick) #Pick an object on Left-click
viz.go()
