                             JumpBy

Moves a CocosNode object simulating a jump movement by modifying it's position attribute.

Example:

# Move the sprite 200 pixels to the right and up
action = JumpBy((100,100),200, 5, 6)
sprite.do( action )            # in 6 seconds, doing 5 jumps
                               # of 200 pixels of height

Methods

	init(self, position=(0,0), height=100, jumps=1, duration=5) Init method
	start(self) Before we start executing an action, self.target is assigned and this method is called.
	update(self, t) Gets called on every frame.
	__reversed__(self)

Gets called on every frame. t is in [0,1] If this action takes 5 seconds to execute, t will be equal to 0 at 0 seconds. t will be 0.5 at 2.5 seconds and t will be 1 at 5sec.
