Build

git clone https://github.com/mengxipeng1122/Cocos2DX-Imgui.git
cd Cocos2DX-Imgui
mkdir bins

Donwload game apk from apkpure, I'm using versioni 1.8.12, and save downloaed apk file as bins/com.ketchapp.knifehit.apk

# decompress downloaded apk
cd bins
mkdir com.ketchapp.knifehit
cd com.ketchapp.knifehit
unzip -x ../com.ketchapp.knifehit.apk
cd ../..
# build jni 
cd jni
#set NDK path, or you can modify the variable defination in jni/Makefile
export NDKPATH=<path to your NDK toolchain> # I'm using r11c, laster version may not work, because the NDK version of this game is not very new
make  # 
# generate patchso.ts
cd ..
make generate_patchso_ts
# install npm modules
npm i
# install game to an Android device, and verify frida connect to this device is ok
# and connect a USB joystick and a mouse to the Android device
make run
# this will start game, and inject frida script to game.

Press button "C" to popup imgui windows. If button "C" is not working, you can modify keyCodeMap in the file jni/main.cpp, this variable is of type std::map, and key is the keyCode, value is the key name in program. Not every USB joystick's keyCode is same.

Window Node Navigator will list all all nodes in current scene. Select one node in this window. Then window Node info will diplay more info of the selected node.

Screen shot

Note

So far, it can show all nodes in current scene. And I am testing with an Android dev board Odroid-N2, and only tested in arm64. And I use a joystick to play game, button C to toggle node viewer.
