An Adventure Game - Part 2

This lab is a continuation of the lab you started in Lab 6. Therefore, if your Lab 6 isn't working, you will need to complete it before continuing on to this assignment.

If you don't remember how to do any of the steps (like, copying, zipping, etc), please refer back to Lab 1.

Required Lab Tasks

Hero Finds a Flower

If the hero encounters a flower, the hero picks it up. The hero should keep track of how many flowers the hero has encountered and picked up. There must be a method named checkForFlower in your Hero class.

Hero Finds a Gold Ball

If the hero encounters a gold ball, the hero picks it up. Picking up a gold ball causes another gold ball to appear somewhere else in the world at a random location. There must be a method named checkForGoldBall in your Hero class.

Hero Finds a Mushroom

Mushrooms disappear when the hero encounters them. If the hero encounters one mushroom, nothing happens in the program. If the hero encounters a second mushroom, the hero should turn into an animal (visually - that is, change the image) and the hero loses all the flowers he/she has been carrying around. The flowers go back into the world at random locations. If the hero encounters three mushrooms, Skull objects are added to the world at random locations. You should add three skulls to the world. There must be a method named checkForMushrooms in your Hero class.

Modify Behavior for Gold Ball

Picking up a gold ball also allows the hero's image to return to normal.

Hero Finds a Teddy Bear

When the hero encounters a teddy bear, the hero picks up the bear and all the skulls leave the world. If when picking up the bear, the hero has more than one flower, then another teddy bear will appear in the world. There must be a method named checkForTeddyBear in your Hero class.

Submitting the Assignment

Once you have completed your work, you will submit the zipped up version of the Lab 7 scenario.

For directions on submitting, please see here.

Please recall that you must achieve a grade of at least 50% on each of the labs to be allowed to take the second practical exam. This means, that your labs are technically all due by the last day of class (December 10th). However, if you want to stay current with the course, I would recommend having this assignment completed within a week.
