Answer 1 · 2020-04-05T06:06:35.000Z

what is ale?

Answer 2 · 2020-04-05T06:12:47.000Z

And this
/riru_unity_example/module/src/main/cpp/soinfo.h:224:5: error: unknown type name 'Elf32_Relr'
/riru_unity_example/module/src/main/cpp/soinfo.h:40:9: error: use of undeclared identifier 'assert'

These errors are from the output of commnad : gralde build

Answer 3 · 2020-04-05T06:15:54.000Z

Use ./gradlew :module:assembleRelease instead of gradle build
soinfo.h is deprecated and i forgot to delete it
Try with latest commit?

Answer 4 · 2020-04-05T06:21:32.000Z

ok.
Now I have a question about il2cpp .
if it is possible to hook one method ,which can tell a button is clicked event and fetch the name of the current scene this button is on .

Answer 5 · 2020-04-05T06:24:57.000Z

afaik every object is a MonoBehavior, maybe try to hook one of the call back in MonoBehavior class?

Answer 6 · 2020-04-05T06:28:04.000Z

so, should I hook libunity.so or libil2cpp.so?

Answer 7 · 2020-04-05T06:30:17.000Z

everything compiled from C# world is in libil2cpp.so. libunity.so provides only Unity runtime.

Answer 8 · 2020-04-05T06:32:08.000Z

I have tried this command ./gradlew :module:assembleRelease
Also gives out some errors.
i.e
/riru_unity_example/module/src/main/cpp/whale/src/base/logging.h:216:9: error: use of undeclared identifier 'abort'
/riru_unity_example/module/src/main/cpp/whale/src/platform/linux/process_map.h:36:16: error: expected unqualified-id

try to upgrade your NDK version?

Answer 10 · 2020-04-05T06:51:22.000Z

upgrade to which version ?
And what is the use of this method:nativeForkAndSpecializePre,I have not find anywhere references it.

Answer 11 · 2020-04-05T06:56:07.000Z

upgrade to which version ?

I'm currently using "NDK (Side by side)" showes in Sdk Manager, idk why it doesn't shows the version number. So I can only recommand you to upgrade with Sdk Manager.

And what is the use of this method:nativeForkAndSpecializePre

it is an export function, called by Riru-Core

Answer 12 · 2020-04-05T07:02:24.000Z

ok. I will try .
///////////////////////////
const Il2CppImage* image = il2cpp_assembly_get_image(assembly_list);
Il2CppClass clazz = il2cpp_class_from_name(image, "UnityEngine.UI", "Button");
hook_each((unsigned long)il2cpp_class_get_method_from_name(clazz, "onClick", 1)->methodPointer, (void*)hook, (void**)&backup);
///////
COuld I use this code to get notified when button is clicked?

Answer 13 · 2020-04-05T07:03:52.000Z

TRY BEFORE ASKING

Answer 14 · 2020-04-05T07:36:05.000Z

afaik every object is a MonoBehavior, maybe try to hook one of the call back in MonoBehavior class?

could you give a example?

Answer 15 · 2020-04-05T07:59:26.000Z

Il2CppClass* clazz = il2cpp_class_from_name(image, "UnityEngine", "MonoBehaviour");
 here print clazz is null.

Answer 16 · 2020-04-05T11:00:31.000Z

struct cSharpByteArray {
size_t idkwhatisthis[3];
size_t length;
char buf[4096];
};

what is the use of this?
thanks

Answer 17 · 2020-04-05T11:07:42.000Z

Parse C# byte array

Answer 18 · 2020-04-05T11:37:07.000Z

Il2CppClass* clazz = il2cpp_class_from_name(image, "UnityEngine.SceneManagement", "SceneManager");
LOGI("hack game begin step2 clazz %p",clazz);
void* monitorfunc=il2cpp_class_get_method_from_name(clazz, "GetActiveScene", 0,0)->methodPointer;

I have successfully got GetActiveScene of class UnityEngine.SceneManagement.Next step, I want to manually call this monitorfunc, how can I achive this in c++?May you give me some hints?
DO i need to dive into the c# class of SceneManagement

Answer 19 · 2020-04-05T11:43:13.000Z

Parse C# byte array
size_t hook(char* instance, cSharpByteArray *src){

I do not know why it need C# byte array here

Answer 20 · 2020-04-05T16:17:11.000Z

can you please explain this code:
hook_each((unsigned long)il2cpp_class_get_method_from_name(clazz, "Your Method", 1)->methodPointer, (void*)hook, (void**)&backup);
why hook takes a cSharpByteArray* param? what does it mean?

Answer 21 · 2020-04-05T16:52:42.000Z

That's the exact same params as the hooked C# function. If your hooked function takes no parameter, leave it blank.

Answer 22 · 2020-04-05T17:37:14.000Z

that sounds strange,
in my idea , il2cpp_class_get_method_from_name returns function point of unity c++ library function , what is the matter of c# ?
please tell me if I am wrong

Answer 23 · 2020-04-05T17:41:21.000Z

All Unity games are written in C#, il2cpp coverts C# to C++ code. In il2cpp arrays have special structure, instead of C array.

Answer 24 · 2020-04-06T03:35:29.000Z

where did you find this two struct:

struct cSharpByteArray {
size_t idkwhatisthis[3];
size_t length;
char buf[4096];
};

struct cSharpString {
size_t address;
size_t nothing;
int length;
char buf[4096];
};

Answer 25 · 2020-04-06T04:33:21.000Z

printing memory and guessing

Answer 26 · 2020-04-06T05:04:50.000Z

Can this repo used with substrate hook library?

Answer 27 · 2020-04-06T05:06:58.000Z

Never tried. If you want to check it out you should use static linking.

Answer 28 · 2020-04-06T07:11:02.000Z

Does il2cpp generate c++ code for each c# script?

Answer 29 · 2020-04-06T14:45:32.000Z

I am curious that why this hook into c# layer?
could you give a practice hook example of this

Answer 30 · 2020-04-06T15:39:47.000Z

Are unity MonoBehaviour api written in c# ? for example SceneManager.GetActiveScene

Answer 31 · 2020-04-06T19:46:26.000Z

Please check Unity's source code
EVERYTHING you need is in C#, or C# with C bindings. You should only care about the C# part.
