Introduction

Welcome back to the final episode of our Tutorial. In this episode, we will be focusing on creating and implementing the clouds in our Game. The clouds will add aesthetic appeal to the background and enhance the overall visual experience. We will walk through the steps of creating the clouds class, drawing the clouds on the background, moving the clouds, and handling respawn and random positioning. So let's dive in and get started!

Creating the Clouds Class

To begin, we need to create a new class for the clouds. This class will hold the necessary properties and functions to handle the clouds' behavior. The ID for the clouds will be set as "clouds", and the source image will be set as "cloud.png".

class Clouds {
    constructor() {
        this.id = "clouds";
        this.source = "image/cloud.png";
    }
}

Drawing the Clouds on the Background

Next, we need to draw the clouds on the background. We will utilize the canvas context to accomplish this. In the background section of our code, we will add the following line to draw the clouds:

ctx.drawImage(clouds.source, clouds.x, clouds.y);

Moving the Clouds

Now, let's focus on moving the clouds across the screen. We will create two variables, cloudX and cloudY, to keep track of the clouds' position. We will initialize cloudX as -60, so the clouds start off the screen. For cloudY, we will generate a random number between 0 and 300 using the Math.floor and Math.random functions.

let cloudX = -60;
let cloudY = Math.floor(Math.random() * 300);

To animate the clouds' movement, we will subtract 2 from cloudX on each frame update. This will make the clouds move from right to left across the screen.

cloudX -= 2;

Respawn and Random Positioning

To ensure the clouds respawn when they go off the screen, we need to check if cloudX + 100 (the width of our cloud image) is less than zero. If it is, we will reset cloudX to the canvas width plus 60 to spawn the clouds on the right side of the screen. Additionally, we will generate a new random cloudY position to give the clouds a different vertical position each time they respawn.

if (cloudX + 100 < 0) {
    cloudX = canvas.width + 60;
    cloudY = Math.floor(Math.random() * 300);
}

Finalizing the Clouds Episode

With these steps completed, we have successfully implemented the clouds in our game. You should now see the clouds drifting across the screen, respawning on the right side, and having different vertical positions each time. Although the bushes might glitch slightly, they do not significantly affect the gameplay. In the next episode, we will delve into the more complex topic of AI. Stay tuned!

Highlights

• Create a new class for the clouds
• Draw the clouds on the background using the canvas context
• Move the clouds across the screen from right to left
• Respawn the clouds on the right side with random vertical positions

FAQ

Q: How do I create a new class for the clouds? A: To create a new class for the clouds, define a constructor function with the necessary properties and functions for the clouds' behavior.

Q: How do I draw the clouds on the background? A: Use the canvas context's drawImage method and specify the clouds' source image, position, and size to draw them on the background.

Q: How do I make the clouds move across the screen? A: Update the clouds' horizontal position (cloudX) on each frame update by subtracting a certain value. This will make the clouds move from right to left.

Q: How do I respawn the clouds on the right side with random vertical positions? A: Check if the clouds' cloudX + 100 is less than zero. If true, reset cloudX to the canvas width plus 60 and generate a new random cloudY position.
