Code for a bouncing ball
All you need is an instance int field to track the vertical speed of the ball. Have the act method increase its value each act cycle to represent acceleration due to gravity. Add the speed value to the vertical location of the ball each act cycle to represent movement. Check for the ball hitting the ground and when needed negate the speed to represent a bounce. You can also add a slight amount to the speed value to represent drag or energy loss during bounce.
You need to provide what code you have so far (at least as far as the ball and its ground/object detection).
However, for gravity:
// instance field int vSpeed; // to track the speed of the ball // in act method vSpeed++; // applying gravity setLoation(getX(), getY()+vSpeed); // moving vertically // check for collision/bounce (above and below -- hint: mind sign of 'vSpeed')
