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;
}
}
}

Commencez par le snippet JavaScript à checkBrickCollisions et suivez son lien avec checkCollisions et moveJumper ; examinez également registerKeyboard pour l’entrée de saut. C’est terminé lorsque le jumper interagit avec les briques en tant que plateformes et qu’un saut ne peut pas être déclenché de manière répétée, ce qui est vérifié en exécutant le jeu canvas.
