Help! Returning the felds value (int)

[DieckyAwsm]

Example int fields offset :

public int fireRate; //0x66

Then this is my hook :

void(*old_UpdateFireRate)(void *instance);
void FireRate(void *instance) {
if (instance != NULL) {
if (FireRate) {
*(int *) ((uint64_t) instance + 0x66) = 4; //

}
}
old_UpdateFireRate(instance);
}

How to returned old or original value of field offset when toggle deactivate?

void (*old_UpdateFireRate)(void* instance);
void FireRate(void* instance) {
   if (instance != NULL) {
      if (FireRate) {
         *(int *)((uint_64t)instance + 0x66) = 4;
      } else {
         old_UpdateFireRate(instance);
      }
   }
}

Try it.
