- previousRoom: stores the previous room of the player.
The methods used in the program are as follows:
- goRoom(String direction): updates the current room of the player based on the specified direction.
- back(): updates the current room of the player to the previous room.
- processCommand(Command command): processes the given command and updates the game state accordingly.
- printLocationInfo(): prints out the current room's description and the items in the room.

Implement the "Add player" menu option. Prompt the user for a new player's jersey number and rating. Append the values to the two vectors. Ex:
Enter a new player's jersey number: 49 Enter the player's rating: 8
Implement the "Replace player" menu option. Prompt the user for the jersey number of the player to replace. If the player is in the roster, then prompt again for a new jersey number and rating. Update the replaced player's jersey number and rating.Ex:
Enter a jersey number: 4 Enter a new jersey number: 12 Enter a rating for the new player: 8

You are writing a game's weapon-spawning system. The weapon that's spawned is completely randomized. There are a few base types of weapons, but some of these have one or more additional functions. The additional functions can apply to any of the types of weapons. Which design pattern is the most useful here?

- Setup Instructions: Create a new class named Lab4 in the edu.ben.labs.lab4 package of your CMSC200 Java Project. Problem Set: Let's place a marker on the circle numbered 1 in the grid below. Then we will toss a coin. If the coin toss resulted in a 'heads', we would move the marker along the path labeled 'H' to the circle numbered 5. If the coin toss resulted in a 'tails', we would move the marker along the path labeled T' to the circle numbered 4. Now we would toss the coin again and move the marker accordingly. This is repeated for any number of coin tosses. The purpose of this problem is to simulate this automata and to report 2 3 the number of the circle on which the marker ends after a series of coin tosses. The marker always begins on the circle numbered 1. 7 Iпрut: Your program should accept a string consisting only of the characters 'h' or t, where each character represents the outcome of a coin toss ('h' - heads, 't - tails). The string is terminated by a #' character.

You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms.

- In c Hangman gameWrite a terminal based on the game of Hangman. In a hangman game, the player is given a wordthat they need to guess, with each letter of the word represented by an underscore/blank. Theplayer tries to guess a letter of the word by entering it into the terminal. If the letter is correct, theblank corresponding to that letter is filled in. If the letter is incorrect, a part of a stick figure isdrawn. The player has a limited number of incorrect guesses before the stick figure is fully drawnand the game is lost. The player wins the game if they guess all the letters of the word before thestick figure is fully drawn.The program should have an array of possible words to choose from. A different word should berandomly chosen from the array every time we run the program.arrow_forwardImplement the "Update player rating" menu option. Prompt the user for a player's jersey number.

Add a label widget to the window object root with the text "Hello, World!". Write a code snippet that adds a button widget to the window object root with the text "Click me!", and binds the button to a function button_click() that prints "Button clicked!" to the console. Hint: You may find the Label, Button, and command attributes in tkinter useful for completing parts 2 and 3 Note: For each part of the question, make sure to provide clear instructions and examples for the code snippets. Also, make sure to test your code snippets to ensure that they work as intended.arrow_forward

If the zombie has 0 or less health, the attack method should add 10 health to the zombie, bringing them closer to being alive so that they will be dead it should then return the zombies health. If the health of the zombie is positive the attack method should return "Zombie is alive, therefore it is not a zombie!". NOTE: This problem statement is extremely vague.
