Yeah, try and try until you success. Before I became a modder, I faced a lot-of-million of trial and errors.

and how to edit this ?
public partial class ActorMonster : ActorBase
{
// Token: 0x060000AF RID: 175 RVA: 0x00002050 File Offset: 0x00000250
[Token(Token = "0x60000A2")]
[Address(RVA = "0xBDAF90", Offset = "0xBDAF90", VA = "0xBDAF90", Slot = "33")]
protected virtual void Attack()
{
}
}

i want the monster become unable to attack me but instead edit it on hex editor ( i already do that and yes it work ) that can't be turned off, i want this function have a switch

It's not hard to do. I suggest you to learn cpp more before getting into this a bit. It's fine that you're doing this without some knowledge, but it'll be way better after you learned it.


Anyways since you're in a class of the monster. You can just NOP the function.

NOP = 00 F0 20 E1
To end the value is BX LR = 1E FF 2F E1
Basically = 00 F0 20 E1 1E FF 2F E1

Or you can probably hook the Attack() and make it do something else.

well,, i'm actually using nop function to make the monster stop attacking me. and you say i can hook the attack() to make it do something else... i think i'm start to understand it. ty for your response btw
 
void _Player_update(void *player){
if(player != NULL){
bool isMine = *(int *)((uint64_t)player + 0x30);

if(isMine){
//ammo
*(int *)((uint64_t)player + 0x1c) = 999;

//health
*(float *)((uint64_t)player + 0x18) = 100.0f;

this one is more easy for me, why ? because the Player_update , Player, Mine, ammo, and health is in the same class ( public class Player : MonoBehaviour ) . what make it hard, is the function that you wanna modify are in the different class. like modifying a shared function.
 
Why it is hard to find correct offset for the mod menu

what is difference between fields and methods. There are some offsets which are encrypted like [ public void LKSFJSAJSNE ]

Hey,
Is it possible to Hook a class without any Update function ?

For ex:
private void Start()
public void OnUpdate()
private void LateUpdate()
private void FiedUpdate()
...

or even without any ?
Thanks

LateUpdate works as well, but I don't know about the others. Just try it, it's trial and error anyways. I mean try, if it doesn't work, then use another method.

So instead of the "private void Update()" offset in the HOOK part, i replace it with the LateUpdate one ? (example)
