Modifying the spawn interval in “setInterval” can adjust the difficulty of the game. Here’s an example of how you could do it:
let spawnRate = 1000; // Intervalo de aparición en milisegundos
function spawnItem() {
// Lógica para generar un nuevo ítem
}
setInterval(spawnItem, spawnRate);
// Para cambiar la dificultad
function setDifficulty(level) {
if (level === ‘easy’) {
spawnRate = 2000;
} else if (level === ‘hard’) {
spawnRate = 500;
}
clearInterval(spawnItem);
setInterval(spawnItem, spawnRate);
}
This allows you to adjust the item spawn rate based on the selected difficulty level.
You can extend the “itemTypes” array to include new items, each with its own image and point value:
let itemTypes = [
{ name: ‘plastic’, image: ‘plastic.png’, points: 10 },
{ name: ‘paper’, image: ‘paper.png’, points: 5 },
// Nuevos ítems
{ name: ‘glass’, image: ‘glass.png’, points: 15 },
{ name: ‘metal’, image: ‘metal.png’, points: 20 }
];
function spawnItem() {
let itemType = itemTypes[Math.floor(Math.random() * itemTypes.length)];
// Lógica para generar el ítem con itemType.image y itemType.points
}
This adds variety to the game and allows players to interact with different types of items.
Adding a countdown timer for a timed game can add to the excitement:
let timeLimit = 60; // Tiempo en segundos
let timer;
function startGame() {
timer = setInterval(countdown, 1000);
}
function countdown() {
if (timeLimit > 0) {
timeLimit–;
console.log(`Tiempo restante: ${timeLimit} segundos`);
} else {
clearInterval(timer);
endGame();
}
}
function endGame() {
console.log(‘¡Tiempo terminado! Fin del juego.’);
}
This adds an element of pressure to the game, causing players to act quickly.
Implementing a system to track and display the highest scores can encourage competition:
let leaderboard = [];
function updateLeaderboard(playerName, score) {
leaderboard.push({ name: playerName, score: score });
leaderboard.sort((a, b) => b.score – a.score);
if (leaderboard.length > 10) {
leaderboard.pop();
}
displayLeaderboard();
}
function displayLeaderboard() {
console.log(‘Tabla de Clasificación:’);
leaderboard.forEach((entry, index) => {
console.log(`${index + 1}. ${entry.name} – ${entry.score} puntos`);
});
}
This allows players to see how they compare to others and can motivate them to improve their scores.
You can modify the game by changing the images, adjusting the gameplay, and adding new features. Here’s a guide:
Modify the itemTypes array in the JavaScript to use your new images:
const itemTypes = [
{ src: ‘images/starfish.png’, points: 10 },
{ src: ‘images/treasure.png’, points: 20 },
{ src: ‘images/seaweed.png’, points: 15 }
];
Adjust the point values for each item to make some items more valuable:
const itemTypes = [
{ src: ‘images/starfish.png’, points: 5 },
{ src: ‘images/treasure.png’, points: 50 },
{ src: ‘images/seaweed.png’, points: 10 }
];
Change how long items stay on the screen before disappearing:
setTimeout(() => {
if (item.parentElement) {
item.remove();
}
To include a new item, follow these steps:
Set the new item: Adds the new item to the itemTypes array with its image path and point value.
const itemTypes = [
{ src: ‘images/starfish.png’, points: 10 },
{ src: ‘images/treasure.png’, points: 20 },
{ src: ‘images/seaweed.png’, points: 15 },
{ src: ‘images/shell.png’, points: 25 } // Nuevo ítem
];
Update item generation logic: Make sure that the game logic that generates the items uses the updated itemTypes array.
function spawnItem() {
let itemType = itemTypes[Math.floor(Math.random() * itemTypes.length)];
// Lógica para generar el ítem con itemType.src y itemType.points
}
For the new item to be visible in the game, you need to make sure that the corresponding image is available in the correct folder.
Save the new image: Saves the image of the new item (shell.png) to the images/ folder.
Image path: images/shell.png
Verify the image path: Make sure that the path specified in the itemTypes array matches the actual location of the image.
const itemTypes = [
{ src: ‘images/starfish.png’, points: 10 },
{ src: ‘images/treasure.png’, points: 20 },
{ src: ‘images/seaweed.png’, points: 15 },
{ src: ‘images/shell.png’, points: 25 } // Nuevo ítem
];
Here’s a full example of what the code would look like after adding the new item:
const itemTypes = [
{ src: ‘images/starfish.png’, points: 10 },
{ src: ‘images/treasure.png’, points: 20 },
{ src: ‘images/seaweed.png’, points: 15 },
{ src: ‘images/shell.png’, points: 25 } // Nuevo ítem
];
function spawnItem() {
let itemType = itemTypes[Math.floor(Math.random() * itemTypes.length)];
// Lógica para generar el ítem con itemType.src y itemType.points
}
// Make sure the ‘shell.png’ image is saved in the ‘images/’ folder
With these steps, you’ll have successfully added a new item type to your game.
To replace the ocean floor with another image, such as a beach or underwater reef, follow these steps:
Select the new background image: Choose an image suitable for the new background, such as a beach or underwater reef, and save it to the images/ folder.
Update CSS: Modify the style of the game container to use the new background image.
.game-container {
background: url(‘images/beach-background.png’) no-repeat center center/cover;
}
background: Sets the new background image (beach-background.png).
no-repeat: Prevents the image from repeating.
center center: Center the image both horizontally and vertically.
cover: Scales the image to cover the entire container.
Replace the ocean background with another image (e.g., beach or underwater reef):
.game-container {
background: url(‘images/beach-background.png’) no-repeat center center/cover;
}
To adjust the sizes and appearance of items in CSS, follow these steps:
Set new item styles: Modify the CSS to change the size and appearance of items.
.item {
width: 60px; /* Ítems más grandes */
height: 60px;
border-radius: 10px; /* Bordes redondeados */
}
width and height: Set the size of items to 60px, making them larger.
border-radius: Adds rounded edges to items with a 10px radius.
Here’s a full example of what the CSS code would look like after making these changes:
.game-container {
background: url(‘images/beach-background.png’) no-repeat center center/cover;
}
.item {
width: 60px; /* Ítems más grandes */
height: 60px;
border-radius: 10px; /* Bordes redondeados */
}
Verify the image path: Make sure that the path specified in the CSS matches the actual location of the image (images/beach-background.png).
Test changes: Run the game to verify that the new background and item styles are applied correctly.
With these steps, you’ll have successfully updated the background and styles of the items in your game.
Display a countdown timer to limit the game duration:
<div class=”timer”>Time Left: <span id=”timeLeft”>60</span> seconds</div>
let timeLeft = 60;
const timer = setInterval(() => {
timeLeft -= 1;
document.getElementById(‘timeLeft’).innerText = timeLeft;
if (timeLeft <= 0) {
clearInterval(timer);
alert(`Game Over! Final Score: ${score}`);
}
}, 1000);
Add items that deduct points if clicked (e.g., a dangerous item like a jellyfish):
const itemTypes = [
{ src: ‘images/starfish.png’, points: 10 },
{ src: ‘images/treasure.png’, points: 20 },
{ src: ‘images/seaweed.png’, points: 15 },
{ src: ‘images/jellyfish.png’, points: -10 } // Negative points
];
Adjust spawn rates and item lifetimes based on difficulty:
function setDifficulty(level) {
if (level === ‘easy’) {
spawnRate = 1500; // Slow spawns
itemLifetime = 5000; // Long lifetime
} else if (level === ‘hard’) {
spawnRate = 800; // Fast spawns
itemLifetime = 2000; // Short lifetime
}
}
