HEALTHY HABITS QUIZ

octubre 23, 2018

Hi There!!! Unit 1 This activity is very important because it's a self-assessment for you. Let's practise making sentences with the vocabulary of this unit. Now, feel free to take the next quiz.

let gameState = 'start'; let paddle_1 = document.querySelector('.paddle_1'); let paddle_2 = document.querySelector('.paddle_2'); let board = document.querySelector('.board'); let initial_ball = document.querySelector('.ball'); let ball = document.querySelector('.ball'); let score_1 = document.querySelector('.player_1_score'); let score_2 = document.querySelector('.player_2_score'); let message = document.querySelector('.message'); let paddle_1_coord = paddle_1.getBoundingClientRect(); let paddle_2_coord = paddle_2.getBoundingClientRect(); let initial_ball_coord = ball.getBoundingClientRect(); let ball_coord = initial_ball_coord; let board_coord = board.getBoundingClientRect(); let paddle_common = document.querySelector('.paddle').getBoundingClientRect(); let dx = Math.floor(Math.random() * 4) + 3; let dy = Math.floor(Math.random() * 4) + 3; let dxd = Math.floor(Math.random() * 2); let dyd = Math.floor(Math.random() * 2); document.addEventListener('keydown', (e) => { if (e.key == 'Enter') { gameState = gameState == 'start' ?
