You can write your script to map keyboard and mouse actions to touches and clicks of the mobile phone according to your needs. Here are the script writing rules.
Script for TikTok and some other games are provided by default. Once enabled, you can play the game with your keyboard and mouse. The default key mapping for PUBG Mobile is as follows:
Instruction for adding new customized mapping files.
Write a customized script and put it in the keymap directory
Click refresh script to show it
Select your script
Connect to your phone, start service and click apply
Press ~ key (the SwitchKey in the key map script) to switch to custom mapping mode
Press the ~ key again to switch back to normal mode
(For games such as PUBG Mobile) If you want to move vehicles with the STEER_WHEEL keys, you need to set the move mode to single rocker mode.
If you don't know how to manually write mapping rules, you can also use the QuickAssistant developed by the author
QuickAssistant Features&Functions:
Play Android mobile games smoothly through keyboard and mouse
Interface based editing of key mapping script
Support pausing the computer screen and using only keyboard and mouse operations
Screenshot&Recording of Mobile Screen
Simple batch control
Android 11+supports playing mobile audio on computers (under development...)
Mobile app installation free
Fast and instant connection
Low latency: USB screen mirroring 1080p latency is within 30ms, which is lower than all screen mirroring software on the market in terms of latency at the same resolution and smoothness
Low CPU usage: pure C++development, high-performance GPU video rendering
High resolution: adjustable, maximum support for native resolution of Android terminals

Learn
If you are interested in it and want to learn how it works but do not know how to get started, you can choose to purchase my recorded video lessons.
It details the development architecture and the development process of the entire software and helps you develop QtScrcpy from scratch.
Everyone is welcome to maintain this project and contribute your own code, but please follow these requirements:
Please open PRs to the dev branch instead of the master branch
Please rebase the original project before opening PRs
Please submit PRs on the principle of "small amounts, many times" (one PR for a change is recommended)
Please keep the code style consistent with the existing style.
Why develop QtScrcpy?
There are several reasons listed below according to importance (high to low).
In the process of learning Qt, I need a real project to try.
I have some background skills in audio and video and I am interested in them.
I have some Android development skills. But I have used it for a long time. I want to consolidate it.
I found scrcpy and decided to re-make it with the new technology stack (C++ + Qt + Opengl + FFmpeg).
Build
All the dependencies are provided and it is easy to compile.
QtScrcpy
Non-Arch Linux Users
Set up the Qt development environment with the official Qt installer or third-party tools such as aqt on the target platform.
Qt version bigger than 5.12 is required. (use MSVC 2019 on Windows)
Clone the project with git clone --recurse-submodules git@github.com:barry-ran/QtScrcpy.git
For Windows, open CMakeLists.txt with QtCreator and compile Release
For Linux, directly run ./ci/linux/build_for_linux.sh "Release"
Note: compiled artifacts are located at output/x64/Release
Arch Linux Users
Install packages: base-devel cmake qt5-base qt5-multimedia qt5-x11extras (qtcreator is recommended)
Clone the project with git clone --recurse-submodules git@github.com:barry-ran/QtScrcpy.git
Run ./ci/linux/build_for_linux.sh "Release"
Scrcpy-Server
Set up Android development environment on the target platform
Open server project in project root with Android Studio
The first time you open it, if you do not have the corresponding version of Gradle, you will be prompted to find Gradle, whether to upgrade Gradle or create it. Select Cancel. After cancelling, you will be prompted to select the location of existing Gradle. Cancel it too and it will download automatically.
After compiling the apk, rename it to scrcpy-server and replace QtScrcpy/QtScrcpyCore/src/third_party/scrcpy-server.

Since it is based on scrcpy, it uses the same license as scrcpy
