I due progetti sul tetto

Word-guess game

Build a five-letter word-guessing game that runs entirely in the browser. You will write the scoring logic that colours each letter green, yellow or grey (including the tricky repeated-letter rule), then wire it to a keyboard-driven board, a message line and saved statistics.

  • score() marks letters in the right spot green.
  • score() marks letters that are in the word but elsewhere yellow.
  • score() handles repeated letters correctly (a letter is only yellow as many times as it appears).
  • The board shows 6 rows of 5 tiles.
  • Typing on the keyboard fills the current row, Backspace deletes, Enter submits.
  • A word that is not in WORDS is rejected with a message.
  • Winning or using all 6 rows shows a message.
  • Games played and wins are saved in localStorage under the key 'wordStats'.

Arcade game

Build a brick-breaker arcade game. The heart of it is two pure functions: collide(), which decides whether a circle touches a rectangle, and step(), which takes the whole game state and returns the next one.

  • collide() detects overlap between the ball and a rectangle.
  • The ball bounces off the left, right and top walls.
  • The ball bounces off the paddle.
  • Hitting a brick removes it and adds 10 points.
  • Missing the ball loses a life and resets the ball.
  • step() uses dt, so movement does not depend on frame rate.
  • Clearing all bricks raises the level and makes the ball faster.
  • Pressing Space toggles paused, and a paused step changes nothing.
  • The game draws on a canvas with requestAnimationFrame.

Domande

Devo installare qualcosa?

No. Tutto funziona nel tuo browser. Per i progetti puoi anche lavorare sul tuo computer e caricare i tuoi file.

Posso saltare quello che conosco già?

Sì. Una volta che possiedi una torre, ogni piano ha un test di salto: segna 8 su 10 e quel piano si apre.

Qual è la politica di restituzione?

Rimborsi entro 5 giorni dall'acquisto. Dopo 5 giorni, nessun rimborso o reso.

Mantengo l'accesso?

Sì. Una torre che acquisti è tua, senza abbonamento.
