Template to Mod* Unity Games in Android

Weekend project to write a pgsharp like tool for any unity game. Targeted game here is called "Knight Unity" which is a pvp server for knight online. (illegal)

• dante-apk contains UI related material for the mod
• dante-rust contains native side of the mod.

Building

• First build dante-apk and replace app-debug.apk in dante-rust/src/payload. Also change APK_SIZE in dante-rust/build.rs according to new apk size.
• Then build dante-rust with cargo +nightly ndk -t arm64-v8a -o ./jniLibs build --release -Z build-std=std,panic_abort
• To build armeabi-v7a version (most emulators use 32 bit android image so you need to build with this.)cargo +nightly ndk -t armeabi-v7a -o ./jniLibs build --release -Z build-std=std,panic_abort but you need to change let mut function_iter = 0u64; to let mut function_iter = 0u32;
• Then replace libmain.so file in your target apk. (You can use apktool)
• Rebuild and sign it. You are good to go.

To do all of this you can use dante-rust/setup.sh. Connect your device with adb and it will do the rest. If target game is already installed it will replace the native library (needs root)

Hacking

Currently this template can hook il2cpp functions via by function name (See game_hook.rs). Also hooks send/recv functions to intercepts game network (See bd.rs)
