Need help with just number 8. The rest of the code is done.ty

BARREL CLASS

PIG CLASS

8. If the user right-clicks on the barrel, the pig "eats" all the mushrooms currently in the barrel and the barrel returns to its original size and original location. This will involve the [act method and fields of the Pig class, the getMushrooms method of the Barrel class, and the reset method of the Barrel class Remembering the original state of the barrel (location and image size) will involve fields of the Barrel class and the addedToworld method of the Barrel class Notes on Step8 This is the hardest part of the assignment. There are essentially three parts to step 8, and I'll discuss each below 1. "If the user right-clicks on the barrel," It seems like this would be handled in the (act method of the Barrel class since we're wanting to detect a click "on the barrel". But: (1) It's the pig that has to take action, not the barrel. (2) Since the pig follows the mouse, if the mouse is over the barrel, the pig is too. These two facts together mean that this step will actually all be handled in the act method of the Pig You'll have to use the Greenfoot.mouseClicked (null) method to detect that a click occurred. If a click has occurred, you will create a MouseInfo object using the Greenfoot.getMouseInfo() method like usual. Then, you can use the mouse.getButton() method to determine if the click was the left, center, or right button. It would be very helpful to view the documentation for the Greenfoot class and read what each of these methods do 2. "the pig eats all the mushrooms currently in the barrel" The pig will have to call the barrel's getMushroom() method to find out how many mushrooms the barrel currently stores. The pig can add this amount to its count of mushrooms eaten. Remember, the mushrooms are already gone from the world - this happened when the barrel "stored them." 3. "and the barrel returns to its original size and original location." This is the purpose of the reset) method in the Barrel class, and the pig will have to call this method. The reset method relies on two things already having happened: (1) Fields have been declared in the Barrel class to record the original location (x and y coordinates) and orignal image size (width and height). (2) These fields have been assigned in the addedToWorld( method of the Barrel class 8.
