Jack loves to do jumping jacks. Create a simulation of Jack consisting of a stick figure and three buttons: start, stop, and quit. If the user clicks the start button, Jack begins jumping; if the user clicks the stop button, Jack stops jumping; if the user clicks the quit button, the program terminates (including closing the window). If the user clicks on the screen anywhere outside of a button, no action occurs. Supply instructions to the user when the simulation starts.
That is the problem i am trying to solve. I created jack and bottons but how am i gonna make it jump up and down ?
