Assessment for Game

A

-Game Ready for Monday, May 3th at 2:00

-game is in .jar file format

-and link works in html file OO.htm

B

-Game Ready for Tuesday May 4th at 2:00 (I we will be installing the games between 2 and 3)

-game is in .jar file format

-and link works in html file OO.htm

Anything less than C or less

To achieve this you can work in teams.

Test on Collisions - Monday 5/10

Section 1

Lesson 1 9/4

  • Name, web-site, and email address on the board)
  • Objective-Introduce class to Web site and class procedures
  • Objective - Start to think about the intricacies of designing a computer game using a simplified version of MineSweep
    • On a piece of paper write down ideas for designing a simple mine sweep game - anything goes
    • Lets brain storm in a group
    • Break into groups for 5 minutes to plan out the design of the game and answer the following questions
      • What will the game do?
      • How to represent it internally?
      • How would you populate the bombs differently for each game
      • Draw your internal representation of the game board
    • Use case scenarios are widely used in the industry. It is where you walk through what a user would do and then you the designer/programmer will calculate how your program will react.
      • Use Case 1: User clicks left clicks on 2,2
      • Use Case 2 - Draw out what the user will see if they Left clicked 0, 3-
        Right click you will see a Flag
      • Use Case - What will the user see if she left clicks in 1,1
      • How to check for bombs
        original
    • What methods do we need
      • what are the methods we need / think of tic tac toe
      • isBomb() -
      • isValidFlag - count
      • getAdjacentLocation()
      • isWinner() -
        • Right or left Click
        • Left click -Is cell a bomb if is exit
        • Left Click and the cell is empty
          • Go through all 8 possible touching cells
          • Display to the user a number or a blank cell
        • Keep doing this till winner- need to keep track of flags and bombs
  • Time Permitting open up Alice
  • Summation - progress report on line
  • Lecture
    • Since the internal representation of mine sweeper records the number of mines around a cell; Write an algorithm that counts the number of randomly placed cells with bombs around and 8 cell area in which a user has picked.
    • What methods do we need
      • what are the methods we need / think of tic tac toe
      • isBomb() -
      • isValidFlag - count
      • getAdjacentLocation()
      • isWinner() -
        • Right or left Click
        • Left click -Is cell a bomb if is exit
        • Left Click and the cell is empty
          • Go through all 8 possible touching cells
          • Display to the user a number or a blank cell
        • Keep doing this till winner- need to keep track of flags and bombs
    • Demo how to run a program in Eclipse and how to make a workspace
    • Assignment 1
    • Assignment 2
      • Create a short-cut to Alice in C -> Documents and Settings- > your account\desktop\Alice\Alice.exe
      • Create a short-cut to Eclipse C-> Eclipse\Eclipse.exe
      • H:/00/Journal/yourFirstInitialLastNameJournal.doc, H:/OO/Alice , H:/OO/workspace (can do this from within Eclipse), H:/OO/MO/Website
    9/29 (still out, email me through eimacs)I've added a Power Point on Chapter 3 of Big Java- Check it out!

Lesson 6 11/30

Lesson 7 - 1/19/2010

Assignment 1/19/2010 - Determine that a collision has happened when the the ball collides with each boundary of the window. Use this code as your foundation

The Tutorials are now working, but through Internet Explorer Only! Eclipse and Java Tutorials

Code for resizable Ellipse

import javax.swing.JComponent;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.geom.Ellipse2D;

/**
A component containing an ellipse filled with your favorite
color that touches the component boundaries.
*/
public class EllipseComponent extends JComponent
{
public void paintComponent(Graphics g)
{
// Draw a large ellipse that touches the boundaries of this component.

Graphics2D g2 = (Graphics2D) g;

double width = getWidth();
double height = getHeight();// it's that easy.

Ellipse2D oval = new Ellipse2D.Double(0, 0, width, height );

g2.setColor(Color.RED);
g2.fill(oval);

g2.setColor(Color.BLACK);
g2.draw(oval);
}
}

Due By Friday 3/5 For Progress Reports
  • A Game Document describing your game and the additions that you have made to the game. This document will be place in a Directory called H:/OO/Game/paFirstGame.doc (Where the first letter is your first initial and the second letter is your second initial) followed by the words FirstGame.
  • Your games should implement the 1.5 java Mouse and Key Listener Interfaces. Refer to the links above and the 1.5 java api.
  • Your game should have a separate classes for each of its' objects for example, a Ball class, a Player class, an Opponent class, etc...
  • All code MUST be aligned correctly
  • All coded MUST be reasonably commented -
    • the top of each class
      • should have your name
      • the class name
      • the purpose of the class
    • each method
      • inputs and outputs
      • description of what it does
  • Your code should run. If it does not run or does not run properly leave me a separate note called MsGold.doc explaining the problems that you have had.
Lesson 9 - 3/9/10Three Players One ClassHow one Lazer ClassDownload the following java files and Main.java Load these files into Eclipse and create 3 Players. Create Four Players from only ONE Class that do the following.
  1. Each Player will be a different Size
  2. Each Player will be a different Color
  3. Each Player will be at a different position
  4. and one Player will only move up and down to whatever keys you like
  5. This MUST be implemented with the new KeyListener Methods.

 

Collisions - 4/9

Better Collision Testing Code

/*
* Ms Gold - test to see if Asteroid is hit by a beam
* x is the x position of the beam
* y is the y position of the beam
* r is the radius of the beam
*/

public void testAstCollision(int x, int y, int r)
{
     /*
      * a is the bounding box for the Asteroid
      * b is the bounding box for the beam
      */
      Rectangle a = new Rectangle(x_pos, y_pos, radius*2, radius*2);
      Rectangle b = new Rectangle(x, y, r*2, r*2);

      if (a.getBounds().intersects(b)){
         x_pos = -100; // temporary solution is to move asteroid off screen
         y_pos = -100;
          System.out.println("GONE");
      }

}

Pick up your Code Here

Examples of changed code

  • General Cleanup
  • added getters and setters
  • Collision Code
  • Removed extraneous code
  • KeyListener
  • Dominic - example Pacman code to follow

Code I did not update

  • Andrew and Paul(I did not know what you need help with)
  • Joe ( Not sure what to help you with)
  • PJ - Looks like your game is finished . Any finishing touches?

 

 

 

 

*************************************************************************************************************

 

Before you hand in code

Code Requirements

Comments
Top of program should include
Your name -
any parameters -
the date -
A description of what the program does -
How to deploy your program outside of Eclipse. I want this tested and don't forget about images.
All instance variables are to be commented
On top of each method -
A explanation of purpose of the method
explain each of the parameters and return values
In addition, comment all important lines of code.

Conventions To Follow

Start class names with a Capital Letter
Start variable names with a lower case letter
Always camelCase - it's easy to type and easy to read
Always indent - code that is not indented I will not be debugged or grade
Always comment - non-commented code will not be graded
