A proof of concept il2cpp mod for BlockadeHax that I scrapped together which shows you how to modify an il2cpp unity game.
Example of invoking an il2cpp method:
auto Assembly = Runtime::il2cpp_assembly_get_image("assemblyname"); //Example: Assembly-CSharp
auto Class = Runtime::il2cpp_class_from_name(Assembly, "namespace", "className"); //If the namespace is not there, just pass in ""
auto Method = Runtime::il2cpp_class_get_method_from_name(Class, "methodName", 0); //Pass in the target method's name, so if I wanted to attack a method called KillCurrentPlayer(), I'd pass in the name KillCurrentPlayer by itself.
auto Result = Runtime::il2cpp_runtime_invoke(Method, NULL, NULL); //Execute the method and get the result as an Il2CppObject which you can do whatever you want with.auto assembly = Runtime::il2cpp_assembly_get_image("UnityEngine.CoreModule");
auto Class = Runtime::il2cpp_class_from_name(assembly, "UnityEngine", "Debug");
auto Method = Runtime::il2cpp_class_get_method_from_name(Class, "Log", 0);
Runtime::il2cpp_runtime_invoke(Method, NULL, new void* [1] { Runtime::il2cpp_string_new("testing") });
