write me some javascript code to run the chrome dinosaur game
Sure! Here's a step-by-step guide to implementing the Chrome Dinosaur Game using JavaScript:
Step 1: Create the required HTML structure
```html
<!DOCTYPE html>
<html>
<head>
<title>Chrome Dinosaur Game</title>
<style>
#game-container {
position: relative;
width: 400px;
height: 150px;
border: 1px solid black;
}
</style>
</head>
<body>
<div id="game-container"></div>
<script src="game.js"></script>
</body>
</html>
```
Step 2: Implement the game logic in JavaScript
Create a new file named `game.js` and add the following code:
```javascript
const gameContainer = document.getElementById('game-container');
const dino = document.createElement('DIV');
dino.style.width = '50px';
dino.style.height = '50px';
dino.style.backgroundColor = 'green';
dino.style.position = 'absolute';
dino.style.bottom = '0';
gameContainer.appendChild(dino);
let isJumping = false;
let gravity = 0.9;
let jumpCount = 0;
function control(event) {
if (event.keyCode === 32) {
if (!isJumping) {
isJumping = true;
jump();
}
}
}
document.addEventListener('keydown', control);
function jump() {
let jumpInterval = setInterval(function () {
let dinoTop = parseInt(window.getComputedStyle(dino).getPropertyValue('top'));
if (jumpCount >= 15) {
clearInterval(jumpInterval);
let fallInterval = setInterval(function () {
if (dinoTop <= 0) {
clearInterval(fallInterval);
isJumping = false;
}
dino.style.top = dinoTop - gravity * 4 + 'px';
dinoTop = parseInt(window.getComputedStyle(dino).getPropertyValue('top'));
}, 20);
}
dino.style.top = dinoTop + 30 + 'px';
jumpCount++;
}, 20);
}
```
Step 3: Open the HTML file in a web browser
Once you have created the HTML file and the JavaScript file, simply open the HTML file in a web browser, and you should be able to play the Chrome Dinosaur Game by pressing the spacebar to jump.
Note: This implementation is a simplified version of the actual Chrome Dinosaur Game and may lack features such as obstacles and scoring.
Here's an example of JavaScript code to run the Chrome Dinosaur Game:
```javascript
var canvas = document.createElement("canvas");
var ctx = canvas.getContext("2d");
document.body.appendChild(canvas);
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
var gameStatus;
var player;
var obstacles = [];
function gameStart() {
gameStatus = "start";
player = new Player(canvas.width / 3, canvas.height - 25);
obstacles.push(new Obstacle(canvas.width, canvas.height - 25));
runGame();
}
function runGame() {
update();
draw();
if (gameStatus === "start") {
requestAnimationFrame(runGame);
}
}
function update() {
player.update();
if (Math.random() < 0.01) {
obstacles.push(new Obstacle(canvas.width, canvas.height - 25));
}
for (var i = 0; i < obstacles.length; i++) {
obstacles[i].update();
if (player.checkCollision(obstacles[i])) {
gameStatus = "end";
}
if (obstacles[i].x < -obstacles[i].width) {
obstacles.splice(i, 1);
}
}
}
function draw() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
player.draw();
for (var i = 0; i < obstacles.length; i++) {
obstacles[i].draw();
}
}
function Player(x, y) {
this.width = 50;
this.height = 50;
this.x = x;
this.y = y;
this.dy = 0;
}
Player.prototype.update = function () {
if (this.y + this.height < canvas.height) {
this.dy += 0.5;
this.y += this.dy;
} else {
this.y = canvas.height - this.height;
this.dy = 0;
}
};
Player.prototype.draw = function () {
ctx.fillStyle = "black";
ctx.fillRect(this.x, this.y, this.width, this.height);
};
Player.prototype.checkCollision = function (obstacle) {
if (
this.x < obstacle.x + obstacle.width &&
this.x + this.width > obstacle.x &&
this.y < obstacle.y + obstacle.height &&
this.y + this.height > obstacle.y
) {
return true;
}
return false;
};
function Obstacle(x, y) {
this.width = 30;
this.height = 60;
this.x = x;
this.y = y - this.height;
this.dx = 5;
}
Obstacle.prototype.update = function () {
this.x -= this.dx;
};
Obstacle.prototype.draw = function () {
ctx.fillStyle = "red";
ctx.fillRect(this.x, this.y, this.width, this.height);
};
document.addEventListener("keydown", function (event) {
if (event.keyCode === 32 && gameStatus === "start") {
player.dy = -10;
} else if (event.keyCode === 32 && gameStatus === "end") {
location.reload();
}
});
gameStart();
```
To run this code, save it in a `.js` file and include it in an HTML document using the `<script>` tag, like this:
```html
<!DOCTYPE html>
<html>
<head>
<title>Chrome Dinosaur Game</title>
</head>
<body>
<script src="your-script.js"></script>
</body>
</html>
```
After doing this, open the HTML file in a web browser, and you should be able to play the Chrome Dinosaur Game.
Certainly! Here's an example of JavaScript code that you can use to run the Chrome Dinosaur game:
```javascript
// First, create an instance of the game
var game = new Runner('.interstitial-wrapper');
// Then, start the game
game.start();
// You can also control the game by using the following functions:
// Jump the dinosaur
game.keyboardController.startJump();
// Duck the dinosaur
game.keyboardController.startDuck();
// Stop jumping or ducking the dinosaur
game.keyboardController.endJump();
game.keyboardController.endDuck();
```
To run this code, you'll need to include the required scripts and assets for the game. You can find these files on the Chrome Dinosaur Game GitHub repository (https://github.com/wayou/t-rex-runner).
Make sure to include the `runner.js` script and the `images/` folder in your HTML file. Additionally, you may need to adjust the CSS and HTML markup to match your website structure.
Remember to run this code in a JavaScript environment that supports the DOM (Document Object Model), as the game relies on the browser's DOM APIs to function correctly.
