help me to check the collision

can you guys help me to make the collision(its in function checkBrickCollisions) with the brick so the player jumps jn them and helpe me make so the jumper jumps only once heres the code (JS)

var canvas = document.getElementById('canvas');
var context = canvas.getContext('2d');

var jumperColor = '#660033';;
var jumperXSpeed = 10;
var gravity = 9.8;

var brickList = [];

var jumper =
{
width: 30,
height: 30,
x: 450,
y: 50,
mass: 100,

speedX: 0,
speedY: 0
}

var brick = createBrick(100, 500, 400, 20);
brickList.push(brick);
brick = createBrick(400, 300, 200, 20);
brickList.push(brick);

registerKeyboard();
setInterval(gameController, 10);

function gameController()
{
draw();
move();
}

function move ()
{
moveJumper()
}

function draw ()
{
clearCanvas();
drawJumper();
drawBricks();
GotoMidGuys();
}

function drawBricks() {
for (var i = 0; i < brickList.length; i++) {
var brick = brickList[i];
context.fillStyle = "#3E263A";
context.fillRect(brick.x, brick.y, brick.width, brick.height);
}
}

function moveJumper()
{
jumper.x += jumper.speedX;
jumper.y += jumper.speedY;

jumper.speedY += 0.2;
if (jumper.speedY >= 10) {
jumper.speedY = 10;
}
}

function getRandomCoordinate()
{
return Math.floor(Math.random() * squareCount + 1);
}

function clearCanvas()
{
context.clearRect(0, 0, 600, 600);
}

function drawJumper ()
{
context.fillStyle = jumperColor;
context.fillRect(jumper.x, jumper.y, jumper.width, jumper.height);
}

function GotoMidGuys()
{
document.getElementById("canvas").style.marginLeft = "auto";
document.getElementById("canvas").style.marginRight = "auto";
canvas.style.display = 'block';
}

function registerKeyboard() {
document.addEventListener('keydown', function (event) {
/*
key codes
W = 119
S = 115
A = 65
D = 68
*/

if(event.keyCode == 87)
{
jumper.speedY = -10;
}
if(event.keyCode == 65)
{
jumper.speedX = -jumperXSpeed;
}
else if(event.keyCode == 68)
{
jumper.speedX = jumperXSpeed;
}
});

document.addEventListener('keyup', function() {
console.log('key up')
if(event.keyCode == 119)
{
}
if(event.keyCode == 65 || event.keyCode == 68)
{
jumper.speedX = 0;
}
});
}

function createBrick(x, y, width, height) {
return {
width: width,
height: height,
x: x,
y: y
}
}

function checkCollisions ()
{
checkBrickcollisions();
}

function checkBrickCollisions ()
{
for (var i = 0; i < brickList.length; i++) {
var brick = brickList[i];
if (jumper.x + jumper.width >= brick.x && jumper.x <= brick.x + brick.width && jumper.y > brick.y && jumper.y <= brick.y + brick.height)
{
jumper.speedY -= jumper.speedY ;
jumper.speedx -= jumper.speedx ;
gravity -= gravity;
}
}
}

checkBrickCollisions の JavaScript スニペットから始め、checkCollisions および moveJumper とどのように関係しているかを追跡します。また、ジャンプ入力について registerKeyboard も調べます。canvas ゲームを実行して確認し、jumper がブロックをプラットフォームとして扱い、ジャンプを繰り返し発動できない状態になれば完了です。
