I made roulette in Java.

The story of creating a roulette game in Java

Introduction

SLP KBIT Advent Calendar 2018 12/5 I made a roulette wheel using Java in a university experiment, so I will introduce it. GitHub. Originally, I was planning to introduce another artifact, but I didn't have enough time to complete it.

What is roulette?

The one in the casino. Wikipedia. There are American style and European style. In the American style, 0/00 exists in addition to the numbers 1 to 36. The European formula is only 0. This time, I chose the American style because I thought that even numbers would be more convenient for programming reasons.

language

We have confirmed the operation with Java> = 9. The reason for using Java is that it was specified in the experiment. heavy.

Original rule

Some rules have been simplified for the sake of simplicity.

• If the dealer goes bankrupt, you win, and if you go bankrupt, you lose.
• It ends when the stake runs out or the body goes bankrupt.
• Do not hang on the line.

Game flow

1. Set where and how much the player bets
2. Lottery
3. Payment processing
4. Bankruptcy judgment if (bankruptcy) goto 6
5. goto 1.
6. Finish

Original design

Roulette has special places such as SMALL and RED. This is expressed as an int type by using the following values. I want to replace it with an enum.

State during operation

1. Bet table

2. Roulette disc

Class design

Progress

• Make the whole game progress
• Main method is here.

InforMation

• Explain the game.
• Shows the remaining time to bet.

AnyNumMoney There are the following variables.

• Initialization variable
• Where you bet
• Bet

Also, as a Static variable, the place where you bet and the number of times you make money are saved separately. By treating this as an array, it is possible to handle where and how much you are betting, and you can obtain the number of the array in which the next value is stored. There is reset as a public method. This initializes all values.

Table

• Set the place and amount for the user to bet.
• Heavy use of JButton

Use the anyNumNomeyNormailize method to normalize the AnyNumMoney array. This is because the element that saves only the place to bet or only the money and does not save the other is useless and is canceled. The public methods are as follows.

1. void setLock(beelean) You will not be able to bet. In an actual casino, you cannot bet due to the time limit. Realize it.

2. beelean getLock() Get if you can bet now.

3. AnyNumMoney[] getNumMoney() Returns an array that stores where and how much you are currently betting.

Number

• Method to get enum definition and NumbersTable value

NumbersTable

• Save the number, SML, and color in ArrayList.

1. public static SpecialNumbers getSpecialNumberByAddress(int)
   Throw a value and take an enum in a special place.

Roulette

• Generate random numbers.

1. int getIntRouletteValue() Take with int.

2. String getStringRouletteValue() Take with String.

MyColor Returns the Color type.

Ball

• Animation of flowing a ball in a disk shape up to a value determined by random numbers
• Take the number to stop in the argument of the constructor.

Call the BalMain class as Windows. Since the BallMain Window operates in a separate thread, if you call it directly from the Main method, the processing of the Main method will proceed before the roulette is finished. To prevent this, use the ckDoingBallMain () method to check if the animation is currently in progress. When finished, close the Window and return to the Main method.

The following is used as the Private class. Or give me a structure.

dPoint As public, it has double type x and y variables.

iPoint Like dPoint, it has int type x and y variables.

Cast Round x and y in dPoint to make iPoint.

NumOrder Save the disc arrangement. The roulette discs are determined in the order of 5,22,34, ... with less regularity, not 0,1,2, .... The class that saves it.

1. int search(int)
   A method that returns the number of the argument value. As an example, search (5) returns 0.

BallMain

• A disc-shaped ball spinning class.
• The animation of spinning the ball itself is driven by threads.
• Take the value to stop and the vertical and horizontal sizes as arguments of the constructor.
• The value to stop is calculated by NumOrder.search (int), which is the number of the disk.
• It stops exquisitely with a black magic code.

1. beelean getThreadStatus()
   Returns by T / F whether the thread is currently running.

Payment Performs monetary processing on users and dealers.

1. void calcEach(Player, Player, int) Calculate by licking the place where the user bet.

2. void clac(Player, Player, int, AnyNumMoney) The inside bet and the outside bet are judged for the place where the user bets.

Wallet Save the player's and dealer's money.

1. Wallet(int) Set the amount of money you have.

2. int getCache() Get your money.

3. void Cache(int) Make a payment. The amount of the argument is deducted from the amount of money you have.

4. boolean isInsolvency() Returns whether it is bankrupt by T / F.

Player Classes about Players and dealers.

Dealer It just inherits Player.

Makefile After git clone, move Directory with cd roulette. After that, execute the following for the operation you want to perform.

Both compile and run

$ make

compile

$ make class

Run

$ make exe

Delete the Class file

$ make clean

Generate jar file

$ make jar

Future outlook

• Implementation of internet competition.
• Increase the reality of tables and roulette discs.

Summary

We introduced the created roulette app. I will paste the running image or sometime soon. For the time being, it is possible to play, so please play. I would be very happy if you could give me any reviews.
