inheritence question
Hi,
I'm trying to make custom class called car a subclass of the VizNode class, but I'm having a few problems. Here is the main part of my constructor for the car class: Code:
class Car(viz.VizNode): def __init__(self, direction = "right", id = sys.carID): randomCar = random.randint(1,14) if (randomCar == 10): randomCar += 1 if (randomCar > 10): self.tempCar = viz.add( "cars\car_" + str(randomCar) + ".ive" ) else: self.tempCar = viz.add( "cars\car_0" + str(randomCar) + ".ive" ) viz.VizNode.__init__( self, self.tempCar.id ) If I add the following code to the car constructor: Code:
self.tempCar.collideBox() self.tempCar.setVelocity([10,0,0]) however, if I type the following code outside of the car class: Code:
viz.go() viz.phys.enable() car = Car() car.collideBox() car.setVelocity([100,0,0]) Cannot collideBox with invalid bounding box collideBox is not the only method that does not work. I've also tried methods like car.setPosition(10,0,0) which also does not do anything. Any ideas? |
