6. Frog Crossing the Pool Add a rectangle (Shapes) to a new world and change its color to blue. This will serve as a swimming pool. Add seven circles (Shapes) to the world—five yellow along the long side of the pool (each one meter apart), one green at the nearest side, and one red at the far edge. The yellow circles are lily pads that float back and forth across the pool. Add a frog, and place it on the green circle. The goal is to make the frog jump from lily pad to lily pad until it gets all the way across the pool. If the frog lands on the water (not on a lily pad), the frog sinks into the pool and the game is over. If the frog jumps all the way across the pool and lands on the red circle at the far edge, the player wins. Your program must place the five yellow circles in a list. Write a method that uses an infinite loop to repeatedly move each of the five yellow circles in the list across the pool and back at different speeds. (The easiest way to do this is to pass a random number to the method to specify the duration for the circle to move across the pool.) Create event handling methods that have the frog jump forward 1 meter if the player presses the key, move left if the player presses the key, and move right if the player presses the key. Connect each event handling method to an event. Attachments
