Here is one way. Depending on your Canvas y , and screen resolution, this can happen slowly or fast as the Clock cycles the pixels.
, the ball jumps, reaches a y value at the top of the screen, then falls immediately. You can code it to do anything else you want:
- it can increment x at the same time it moves upward if you code it to.
- look for a collision with a sprite and then do something dramatic randomly or at once.
- randomly jump to the max or an intermediate position of the y axis
- make it jump 'faster' by increasing the pixel increment from 1 to 2 or 3 etc.
- use accelerometer to change the trajectory of the jump on the fly (or just add a button to increase x each time it is pressed.
- etc.
