• Parse Unity's method m / class c / field f / instance lfs / lfp
• parse runtime method argument b / bt / nop function n / detachAll and clean cache D
• (Batch) Hook B/BF/BN for commonly used functions, modify function return value setFunctionXXX, setActive to set gameobject active
• Wrapped "Interceptor.attach" to make it easier to use from the command line A(ptr,(args)=>{},(ret)=>{})
• More convenient to find function findMethods / findClasses and call function callFunction / findExport to find exports function
• showMethodInfo help us to Simply get the details of an Il2cppMethod*, and getting the details of a game object useshowGameObject
• Object hierarchy PrintHierarchy / type hierarchy showTypeParent
• Disassemble showAsm with frida and method information, seeHexA means hexdump
• breakWithStack More symbol parsing for il2cpp, breakWithArgs just show args
• Commonly used Hook package HookOnPointerClick / HookSetActive / B_Button / HookPlayerPrefs soon ...
• Parse mount script showComponents alias PrintHierarchyWithComponents is also introduced !not alway work!
• JNI RegisterNatives Hook (impl in JNIHelper, default off [not stable]), using JNIHelper.cacheRegisterNativeItem to get info !testing!
• Using QBDI to simulate the execution of the function, using t(methoinfo) or traceFunction(mPtr) to enable replacement hook !testing!
• 😕 😕 😕
