Floors/Floors.cpp@9:5e53bca2a4c2, 2019-04-16 (annotated)

Revision:
9:5e53bca2a4c2
Parent:
8:90e789413e0b

Changed the values of the positions and velocities to vectors so that they are easier to manipulate. I made use of the float absolute function (fabs) function to make the ball decelerate to a zero velocity while going upwards.
