This time you will take away some of Clara’s autonomy to develop a video game. The game you have to create is the old PC game called Sokoban. You must use the initial code and add keyboard input for the arrow keys. Pressing the “left arrow” button must result Clara making one step left. Similar, pressing “right arrow”, “forward arrow” and “back arrow” must result making Clara move one step in the corresponding direction. Keyboard input can be processed using the getKey() method as String key = getKey(); And then the value of key can be compared against the string representation of the name of the corresponding key. The essence of the Sokoban game is to push all mushrooms located in the world (Figure 1) on top of the special mushroom places while using the minimal possible number of moves. The successful completion of one of the levels is shown in Figure 2. To complete this problem you must write all the necessary code inside the act() method of MyClara. Notice that there are new methods available to you in this practical.
