Help! How to executed function

[Meepoooo]

protected ObscuredInt _currentRoomID; // 0x18
// RVA: 0x1113008 Offset: 0x1113008 VA: 0x1113008
private void room_update() { }
// RVA: 0x1113518 Offset: 0x1113518 VA: 0x1113518 Slot: 25
protected override void OnEnterDoorAfter() { }
bool istele;
int teleValue;
void(* old_UpdateRoom)(void * instance);
void UpdateRoom(void*instance) {
if(instance != NULL) {
if(istele) {
istele = false;
*(int *)((uint32_t ) instance + 0x18, teleValue);
}
}
old_UpdateRoom(instance);
}
MSHookFunction((void *) getAbsoluteAddress("libil2cpp.so", 0x1113008), (void*)UpdateRoom, (void**)&old_UpdateRoom);

the problem is: the update function will update when the openDoorAfter function is executed.
help me How to call openDoorAfter function so that update hook can work.

if(istele){
*(int *)((uint32_t)instance + 0x18) = teleValue;
}

Make a function pointer to openafterdoor then call your pointer in the update.

i was try like this but did work!

protected ObscuredInt _currentRoomID; // 0x18
// RVA: 0x1113008 Offset: 0x1113008 VA: 0x1113008
private void room_update() { }
// RVA: 0x1113518 Offset: 0x1113518 VA: 0x1113518 Slot: 25
protected override void OnEnterDoorAfter() { }
bool istele;
int teleValue;
void( * onEnterDoorAfter)(void * instance);
void(* old_UpdateRoom)(void * instance);
void UpdateRoom(void*instance) {
if(instance != NULL) {
if(istele) {
istele = false;
*(int *)((uint32_t ) instance + 0x18, teleValue);
onEnterDoorAfter(instance);   
}
}
old_UpdateRoom(instance);
}
MSHookFunction((void *) getAbsoluteAddress("libil2cpp.so", 0x1113008), (void*)UpdateRoom, (void**)&old_UpdateRoom);
onEnterDoorAfter = (void (*) (void *))getAbsoluteAddress(targetLibName, 0x1113518);

onEnterDoorAfter = (void (*) (void *))getAbsoluteAddress(targetLibName, 0x1113518);

looks like it's wrong

void(*old_onEnterDoorAfter)(void *instance);
void _OnEnterDoorAfter(void*instance) {

if(instance != NULL) {

if(teleValue > 1) {

*(int *)((uint32_t ) instance + 0x18) = teleValue;
 

}

}

old_onEnterDoorAfter(instance);

}

Thanks I learned bit from this

Hey, i also have a question about calling functions.
When im trying to call a function called DeleteAllBloons() from an update function, the game crashes. (i am advanced in c++)

This is how my code snippet looks like :



// The function inside dump.cs/Assembly-CSharp.dll

// Assets.Scripts.Unity.UI_New.InGame.InGame
// Token: 0x06007061 RID: 28769 RVA: 0x00002053 File Offset: 0x00000253
[Token(Token = "0x6007061")]
[Address(RVA = "0x1132848", Offset = "0x1132848", VA = "0x1132848")]
public void DeleteAllBloons()
{
}

//the update function im using

// Assets.Scripts.Unity.Game
// Token: 0x06004A9B RID: 19099 RVA: 0x00002053 File Offset: 0x00000253
[Token(Token = "0x6004A9B")]
[Address(RVA = "0xDCA4A0", Offset = "0xDCA4A0", VA = "0xDCA4A0")]
private void Update()
{
}

//offsets for funcs

enum Offsets {

    GameUpdateOffset = 0xDCA4A0,

};

//game update func and function pointer

void (*DeleteAllBloons)(void *instance);

void *gameUpdateInst;

void (*old_GameUpdate)(void *instance);
void GameUpdate(void *instance) {

    if(instance != NULL) {

        gameUpdateInst = instance;

    }

    old_GameUpdate(instance);

}

//inside the button

if (gameUpdateInst != NULL) {
    DeleteAllBloons(gameUpdateInst);
}

// inside of hack_thread pointer after the lib is loaded

DeleteAllBloons = (void (*)(void*))getAbsoluteAddress(targetLibName, 0x1132848);



MSHookFunction((void*)getAbsoluteAddress(targetLibName, Offsets::GameUpdateOffset), (void*) GameUpdate, (void **)&old_GameUpdate);

Sorry, forgot to mention the game's name : Bloons TD6

Im still unable to create threads, because i forgot which requirements i had to meet.
