Answer 2

Step 1: delete 6 of your 7 duplicate posts. Gonna assume there was a technical glitch there since all the posts are identical.

Answer 3

Step 2: there are a lot of problems here, but you can start by just wrapping everything in one window.onload (this will require some } hunting) and then following the error messages.

Answer 4

A bit better, but now combine the two window.onload into one, otherwise they can't talk to each other. Then you'll get useful error messages.

Answer 5

update your javascript with the following:

// Get the canvas and button elements
var canvas = document.getElementById("canvas");
var jumpButton = document.getElementById("jump");

// Set up the canvas context
var context = canvas.getContext("2d");
context.fillStyle = "#ff0000";

// Set up initial ball position and velocity
var ball = { x: 100, y: 100, radius: 20, dy: 0, gravity: 0.5 };

// Function to update the ball position
function updateBall() {
context.clearRect(0, 0, canvas.width, canvas.height);
context.beginPath();
context.arc(ball.x, ball.y, ball.radius, 0, Math.PI * 2);
context.fill();

// Apply gravity to the ball
ball.y += ball.dy;
ball.dy += ball.gravity;

// Bounce the ball off the ground
if (ball.y + ball.radius > canvas.height) {
ball.y = canvas.height - ball.radius;
ball.dy *= -0.8; // Reverse the velocity and add some damping
}
}

// Function to handle the jump button click event
function handleJump() {
// Increase the ball's upward velocity
ball.dy = -10;
}

// Add event listener to the jump button
jumpButton.addEventListener("click", handleJump);

// Update the ball position on each frame
function animate() {
requestAnimationFrame(animate);
updateBall();
}

// Start the animation
animate();
