In VMK 20A I create the PickupArrows class used to animate, render and keep track of the arrow pack pickup object. Also in this VMK, the Integrator1 class
from the physics engine is imported.
Using the class created in the previous VMK, in VMK 20B, updates are made to the Player class and to the Scene. When you're done you will see the pack of arrows animating and you will be able to pick them up and have them respawn.
