🎯 Introduction

In this article, we will explore how to automate mobile apps or games using Python. Specifically, we will focus on creating an AI using a powerful computer vision library called OpenCV to play the game of ZigZag. We will cover the setup process, capturing the location of the ball, finding the edges of the track, adjusting parameters, and testing the program. By the end of this article, you will have the knowledge to automate games and achieve high scores effortlessly.

🔧 Setting up the Environment

Before we dive into the details, let's set up our development environment. We will be using an emulator to simulate the game on a computer. LDPlayer is one of the popular emulators we can use, but feel free to choose any emulator that suits your preferences. Once the emulator is set up, we can install the ZigZag game from the Play Store.

🎮 Understanding the Game

ZigZag is a simple game where the player taps the screen to change the ball's direction and tries to stay on the track. The objective is to score as high as possible while navigating through a winding path. The game features trophies and achievements that add an extra challenge.

📷 Capturing the Ball's Location

To create an AI that can play ZigZag, we need to track the location of the ball on the screen. OpenCV provides a module called Hue Circles that simplifies this task. By feeding the game's screenshot into our program, we can use Hue Circles to detect the ball's x and y location, as well as its radius. This allows us to track the ball's movement in real-time.

🔍 Finding the Edges of the Track

In addition to the ball's location, we also need to find the edges of the track. OpenCV's Hue Lines module helps us achieve this. By painting lines on the screen as the ball progresses through the track, we can create a visual representation of the track's edges. We adjust the parameters of this module to identify the edges accurately, even in the presence of distractions or color variations.

🧩 Adjusting Parameters

Finding the right parameters for our program is a crucial step in ensuring its accuracy. We use a separate program called Line Detection, which is available on GitHub, to fine-tune these parameters easily. By manipulating sliders, we can adjust parameters such as hue, saturation, Vibrance, line size, and gap size. This helps us find the optimal values that produce reliable results.

🚫 Masking Out Distractions

To prevent distractions like exploding diamonds from interfering with our AI's decision-making process, we implement a mask to ignore specific colors. This involves removing unwanted elements, such as diamonds, from our program's view. By defining a narrow window and applying a mask based on color, we simplify the image processing, enhancing our AI's ability to focus on the track's edges.

⚙️ Testing the Program

With all the components in place, we can now test our program. By continuously feeding data through the software, we observe how it accurately tracks the edges and adjusts the ball's movement accordingly. We also address any missed or inconsistent edges by incorporating additional checks for white values on the sides of the track.

🏆 Achieving the Thousand Point Trophy

The ultimate challenge in ZigZag is achieving a thousand points, a trophy that only a small percentage of players have attained. To accomplish this feat, we design our AI to play the game relentlessly, automating the process to run for extended periods. Additionally, we unlock other trophies and explore in-depth strategies to maximize the game's potential.

🔚 Conclusion

In conclusion, by leveraging the power of OpenCV and automation techniques, we can create an AI that excels at playing mobile games like ZigZag. Through a careful setup process, accurate location tracking, edge detection, and parameter adjustments, we can achieve remarkable results and surpass human performance. With this newfound knowledge, you can apply these techniques to other games and explore the exciting possibilities of automation.
