Concept

Online abacus multiplayer game where players can join public or private games
Select number of digits and operations for problems before starting
Solo mode with self-inputted or generated problems
Will use arrays to track keyboard input to abacus class

Wireframes

Examples

Work plan

Start by building abacus display and operations with keyboard controls
Focus on optimizing response time, possibly with Javascript
Random problem generator that takes number of digits as parameter
Multiplayer games come after basics

Capture the moment

N@tM: 4/4

• Theme: 1/1, setup with frontend on display and Soren's abacus to use for demo
• Presentation: 1/1, highlighted specific details of work and made connections between core functions and code principles
• Professionalism: 1/1

Backend: 4/5

• Server
• Client
• Client Handler
• No database or APIs, going to add login system with user data

Frontend: 2.3/3

• Code with Javascript
• Runtime
• No Fetch

Insights

Methods

• AP FRQ
• Essentially a function in Java that can be called after being defined in a class
• Use methodName(); syntax to call

public static int numberOfLeapYears(int year1, int year2) {
   int counter = int year1;
   for (int a = year1; a <= year2; a++) { // taking a as a parameter, setting boundaries as between year1 and year2
      if (isLeapYear(a)) { // checking if year value is leapyear
         counter++; // adding 1 to counter if true
         }
      }
   return counter; // returning final count after 
   }

Control Structures

• Case handling with scanner input
• Used to handle exceptions and selection
• Main ones are if/else (with or without case handling) and for/while loops

if(condition 1) {
    // code for if condition is true
} else if (condition 2) {
    // code for if condition 2is true
} else if (condition 3) {
    // code for if condition 3 is true
} else {
    // code for if all other conditions are false
}

• For loop

                for (int row = 0; row < monkeyCount; row++) {  //cycles through "cells" of 2d array

                    // prints specific part of the monkey from the column
                    System.out.print(monkeys[row][col] + " ");

                }

                //this new line gives separation between stanza of poem
                System.out.println();
            }

W3SCHOOLS

Abacus game

• Website to teach the basics of using an abacus
• Informational page as well as competitive practice/game mode
• Practice page where user is given calculations to do (can select difficulty)
• Competition mode where user can play against another user or a bot, each win/loss leads to change in digits of calculations (5-20)

Work delegation

• Soren: teach/refer to resources for how an abacus works (probably cover info page?), code other miscellaneous features
• Avinh and Allie: integrate main features along with Soren, work on CSS styling
• Michael: deployment/other assignments

abacus battle royal:

* like tetris 99 for abacus

• Deploy the website on AWS or raspberry PI
• Figure out how to connect multiple computers to one host idk man

• compares two users and makes them duel in high combat
• they both are given math problems and whoever does it slower gains heat level
• keeps looping for multiple users until there is only one winner
• can do other things later to make the game more interesting

Review AP Classroom videos and include content in presentation
Present using wiki page?

Purpose and objectives: explain concept and purpose of Objects in Java, provide examples and problems involving Object code
Rip example problems from w3schools

Homework?

• A class that does computation with a datastructure that can be viewed as an abacus
• A 2d array [[column], [[Top notch], [# in bottom notches]], [1, 2], [0, 4], [0, 0]]
• Converts abacus notation into decimal [[0, 2], [1, 4], [1, 2]] = 297
• Keeps track of user heat level (like tetris 99)
• If heat level is too high user loses and they get a lose screen and is kicked from the game
• heat level is given by the Game class if they compute something slower
