Solved Help How to call void in lgl mod menu

[asdsfasfasfafa]

Note: I'm a beginner and I'm Japanese. I've only used C++ a little.
I looked at various sample codes and threads, But eventually it crashes
Target function
[Address(RVA = "0x18E60AC", Offset = "0x18E60AC", VA = "0x18E60AC")]
public void Jump(){}
the code I made

#include <And64InlineHook/And64InlineHook.hpp>

void (*old_alwaysjump)(void *instance);
void alwaysjump(void* instance) {
    if (instance != NULL) {
        alwaysjumpbtn = instance; // It could be some functions are missing in this line.
    }
    return old_alwaysjump(instance); // *return* is missing here.
}

jobjectArray GetFeatureList(JNIEnv *env, jobject context) {
        do {
        sleep(1);
    } while (!isLibraryLoaded(targetLibName));
    A64HookFunction((void*)getAbsoluteAddress("libil2cpp.so", 0x18E60AC), (void*)alwaysjump, (void **)&old_alwaysjump);
    const char *features[] = {
            OBFUSCATE("Button_test1")
        };
    
void Changes(JNIEnv *env, jclass clazz, jobject obj,
                                        jint featNum, jstring featName, jint value,
                                        jboolean boolean, jstring str) {
        switch (featNum) {
        case 0:
            if (alwaysjump != NULL)
                old_alwaysjump(alwaysjumpbtn);
            break;
        }

You need to hook void Jump through a void Update function. Look to see if there is Update, LateUpdate, or FixedUpdate in the same class then you can hook it like this...

bool AlwaysJump;

void (*Jump)(void *instance);
void (*old_Update)(void *instance);
void Update(void *instance) {
    if(instance!=NULL) {
        if(AlwaysJump) {
            Jump(instance);
        }
    }
    old_Update(instance);
}




case 0:
    AlwaysJump = !AlwaysJump;
    break;

Hmm... Excuse me, where do you insert the Update offset? FixedUpdate exists in the same class.
Or hook by function name?
Also, A64HookFunction is not necessary?

Insert the Update offset on the hack_thread like this

// targetLibName can be replaced by a string of the lib name
A64HookFunction((void *)getAbsoluteAddress(targetLibName, 0xOFFSET), (void *)Update, (void **)&old_Update); // For arm64 only
// OR
MSHookFunction((void *)getAbsoluteAddress(targetLibName, 0xOFFSET), (void *)Update, (void **)&old_Update); // For arm32 only
// OR
// HOOK function uses string for offset because it uses string2Offset (converts string to offset)
HOOK("0xOFFSET", Update, old_Update); // Will use MSHookFunction or A64HookFunction depending on what lib is being used

// targetLibName can be replaced by a string of the lib name
A64HookFunction((void *)getAbsoluteAddress(targetLibName, 0xOFFSET), (void *)Update, (void **)&old_Update); // For arm64 only

// HOOK function uses string for offset because it uses string2Offset (converts string to offset)
HOOK("0xOFFSET", Update, old_Update); // Will use MSHookFunction or A64HookFunction depending on what lib is being used

It worked fine and I was able to call void.
Thanks to libModz and ZealZenS.
This will be my final code :

#define targetLibName OBFUSCATE("libil2cpp.so")
#include <And64InlineHook/And64InlineHook.hpp>

bool AlwaysJump;

void (*Jump)(void *instance);
void (*old_Update)(void *instance);
void Update(void *instance) {
    if(instance!=NULL) {
        if(AlwaysJump) {
            Jump(instance);
        }
    }
    old_Update(instance);
}

void *hack_thread(void *) {
    //Check if target lib is loaded
    do {
        sleep(1);
    } while (!isLibraryLoaded(targetLibName));
    A64HookFunction((void *)getAbsoluteAddress(targetLibName, 0x18E48B4), (void *)Update, (void **)&old_Update);
    A64HookFunction((void*)getAbsoluteAddress(targetLibName, 0x18E60AC), (void*)AlwaysJump, (void **)&Jump);
}

jobjectArray GetFeatureList(JNIEnv *env, jobject context) {
    jobjectArray ret;
    const char *features[] = {
        OBFUSCATE("Button_alwayjump"),
    };
}

void Changes(JNIEnv *env, jclass clazz, jobject obj,
                                        jint featNum, jstring featName, jint value,
                                        jboolean boolean, jstring str) {
    switch (featNum) {
        case 0:
            AlwaysJump = !AlwaysJump;
            break;
    }
}

So... can you mark it as solved that way?

Thread will be set to "solved" and closed.
When you're not happy with that just send me a message and i will re-open the thread for you.

Thanks.
