//Can anyone guide me on how to do this..
Let's create a simulation. Children are out Trick Or Treating in various costumes having a great time. But real monsters are lurking about trying to get them! Imagine your neighborhood plotted out on graph paper with each co-ordinate x and y. The trick or treaters are at their co-ordinates and various monsters are at their own co-ordinates. If the trick or treater plays a trick on a monster, it may dispel the monster. However, if the monster attacks first, it may be the end of our trick or treater.
* Classes have their own files
* Create UML diagrams for the classes. We will use 2 classes for the monsters and trick or treaters and a main class you will name ProjectFear. Use following information to determine the variables with their ranges, default values, etc:
Added Classes:
Class Monster
variables (remember to make them all private to protect them, and set default values in the constructors.
- String monsterName, Count Dracula, Red Dragon, Skeleton, etc.
- String weapon
- int weaponType (ex: 0=fangs, 1=breathes fire, 2=claws, 3=spits…)
- int xPosition
- int yPosition
methods
- Monster() at least 2 constructors. Set default values for those not passed into the constructor.
- get() methods
- set() methods, this is where you check if the input is valid. String length and number range (hint, how large is your map?).
- attack(x, y) x,y of target. Target must be same position of monster unless range attack. Suggestions, 0-5 = melee (bite, claw, etc), 6+ range (spit, fire breath, etc)
- move(x, y) updates xPosition, yPosition using the set() methods.
- toString() returns a string to print info on the monster.
Class TrickOrTreater
variables (remember to make them all private to protect them, and set default values in the constructors.
- name of the trick or treater
- String costume
- String trickType, scream, toiletPaper the monster, etc.
- int xPosition
- int yPosition
methods
- TrickOrTreater() at least 2 constructors. Set default values for those not passed into the constructor.
- get() methods
- set() methods, this is where you check if the input is valid. String length and number range.
- attack(x, y) x,y of target.
- move(x, y) x,y is the destination, update xPosition, yPosition
- toString() returns a string to print info on the trick or treater.
* Attacks in this case shouldn't be printed in the class/object since the victim isn't known, only the coordinates of the victim. Please think about this fact so you'll realize this when designing in the future.
* test RIGOROUSLY everything in a main() method with command line inputs especially get(), set() and attack() methods
* create a package, compress it into a .jar file, import the .jar file into a new project
1. be sure the private methods & variables you want private, are declared private and public are declared public
2. right-click on the project name on the left side of the screen
3. select "Properties" on the drop-down menu
4. under "Categories:", then "Build", then click on the bullet called "Packaging"
5. check the box next to, "Compress JAR File"
6. next, Clean and Build
7. start a NEW project and call it anything
8. right-click the "Libraries folder in your new project and select "Add JAR/Folder
9. find your new .jar file and add it ex: import ProjectFear.Monster;
* Finally, after you import your new package into a new project, test it all again.
Once completed, use this checklist:
CLASSES
- classes created correctly& in separate files
- complete and correct info. at the top
- formatted correctly
- correct naming convention
- private variables
- correct use of getters & setters
- overloaded constructors
- overridden toString() method
MAIN
- project compiles
- project runs without crashing
- object instantiation
- range checking
- use of move()
- use of toString()
