AutoX – Lazy loading of objects and image resources + Storage persistence
AutoX-lazy loading of objects and image resources + Storage persistence 1. Usage scenarios There are many scenarios that require lazy loading. The first time I needed the lazy loading function was when writing a game automation script. I needed to detect the coordinates of an item in advance before subsequent clicks. The item’s position on […]
AutoX.js – openCV multi-resolution image finding
AutoX.js – openCV multi-resolution image search 1. Cause There are two methods related to finding images in AutoXjs, findImage and matchTemplate. I have never found any problems before. However, when I tested the image search recently, the outlines of the large image and the template image were clear, but I could not find the image. […]
Ticket grabbing based on the automation tool autox.js (Maoyan)
1. I saw information about how difficult it is to grab tickets to Jay Chou and JJ Lin’s concerts in Moments, so I studied for a while and wrote an automated ticket grabbing script using autox.js. The ticket purchase page automatically clicks to place an order (only for Android phones). 2. Script operation diagram 3. […]
Autox.js script development environment construction, from case to packaged apk (detailed process)
1. Introduction After thinking about it again, Autox.js is continuously maintained based on Auto.js 4.1.1, so I plan to build the Autox.js environment directly. 2. Construction 1. Install VSCode. 2. Install the autox.js plug-in. If you have used the auto.js plug-in before, you need to remove it to avoid affecting the use of the autox.js […]

Henan 2023CCPC Problem G. Toxel and Character Painting
One day, Toxel found a mathematical expression of the form x^y, where x and y are both positive integers. He wanted to draw this expression into a character painting in a “self-contained” way. Specifically, Toxel will first evaluate x^y to be equal to z. If z ≤ 10^18, Toxel will plot x y = z; […]
