Jogo de advinhação em Ruby

This example demonstrates a Ruby number-guessing game where the player attempts to identify a random integer between 1 and 100. The program provides textual feedback after each guess, indicating whether the target number is higher or lower. The code uses `Random.rand` to generate the secret number, `gets.to_i` for player input, and conditional `puts` statements to guide the player. The refactored version replaces `if/else` logic with inline modifiers, showing a simplified alternative for the same feedback logic. The game loops until the player quits, tracking the number of attempts per round.

Five blue circles with black outlines are placed at fixed coordinates on a 960-by-500 SVG canvas. Each circle can be dragged interactively using the d3.drag behavior, which updates the circle’s cx and cy attributes in response to pointer movement. The example demonstrates basic SVG circle rendering with D3 v4’s data join and drag event handling, using hardcoded coordinate data.

Gist 53ed6317be002b4e1f4aa1a90e307670

This visualization shows a plain-text cheat sheet of keyboard shortcuts for general computing, terminals, browsers, touchpads, Slack, and VS Code. It displays the raw text data without parsing or transforming it. The example uses a simple HTML document with no external JavaScript libraries, relying on standard browser rendering to present the static content directly from the gist file. The code contains no interactive or data-driven elements.

Jogo Jokenpo em Ruby

This example shows a command-line Rock-Paper-Scissors game implemented in Ruby, where a player competes against a randomly choosing computer opponent. The code defines a `calcula_vencedor` function that determines the winner based on the modulo of the difference between choices, while a hash maps numeric options to the game’s three gestures. The main loop uses `gets` for player input, validates choices, and generates the computer’s pick with `Random.rand`. The program runs repeatedly until the player opts out, ending with a farewell message.

Mini jogo de RPG em Ruby

This example shows a text-based combat simulation between a hero and a series of monsters, tracking the hero's energy and kill count until the hero dies. It implements a turn-based loop where the hero (an instance of the `Heroi` class) and a `Monstro` instance alternately call the `bater` method, reducing each other's `energia` attribute with random attack values. The code uses Ruby's `Random.rand` to determine damage and relies on class attributes such as `energia`, `ataque`, and `numero_de_mortos` to manage state, with the process repeating via nested `while` loops until one character’s energy drops to zero.

Jogo de advinhação em Ruby

This example shows a Ruby terminal word-guessing game where the player must uncover a randomly selected word from a fixed list of ten animal names. The game displays a partially hidden word as underscores, prompts for letter guesses, and reveals correct matches iteratively. It uses Ruby core methods such as `Array#sample` to choose the word, `Array#times` with a block to build the underscore pattern, `String#each_char` to iterate through the target word’s letters, and `Array#join` with `String#count` to detect remaining blanks. The code runs purely via standard input/output with `gets.chomp`, and loops until the word is fully guessed or the player opts to restart.

Exemplo simples de CRUD de uma Agenda em Ruby

This example presents a simple address book CRUD (Create, Read, Update, Delete) interface built in Ruby. The script uses a core Ruby `Hash` to store contact names and their associated phone numbers, with a `while true` loop and a `case` statement providing a text-based menu. User input is handled with `gets.chomp`, and `to_sym` converts names into hash keys. The code demonstrates adding, updating, displaying, and deleting entries, printing each action’s confirmation or error message directly to the console. The data is entirely held in memory, and no external libraries or file persistence are used.
