WEEK 05 - ICM
Because I can't precisely control the X coordinate of the balloon due to the map equation for its motion, I built two buildings besides to reduce the uncontrollable feeling when use mousePressed to release a balloon.
I also tried to use mouseDragged and mousePressed to add/delete balloons. Sometimes it works but sometimes cannot delete it but only change a little position of the pressed balloon.
Need time to get used to the object oriented programming.
