JavaScript coding exercise that involves creating a basic game using the HTML canvas element. Overall, this exercise demonstrates how to use JavaScript to create interactive animations on the web using the canvas element. The requestAnimationFrame() function ensures that the animation runs at the optimal frame rate for the user's browser. We then create a draw() function to clear the canvas and draw the ball on each frame of the animation.įinally, we create a main loop using window.requestAnimationFrame(), which repeatedly calls the updateBall() and draw() functions to animate the ball. We create a drawBall() function to draw the ball on the canvas, and an updateBall() function to update its position and velocity. Match 3 of the same color to pop them all and score points. Bouncing Balls How to play Shoot the colored balls at the matching colors. This game is bubble-popping action at its finest. Pop all of the bubbles while battling against the speed of a 1000T weight. We then set the initial position and velocity of the ball, as well as its radius and color. Bouncing Balls is a bubble-shooting match-3 game. We start by getting the canvas element and its context using JavaScript. In this exercise, we use the canvas element to create a bouncing ball animation.
