Help! Help Hook Vector3

public void MovePosition(Vector3 pos)
My code that doesn't work, I tried to change it but it doesn't work
Vector3 IsTeleport;

void (*Teleport)(void *instance, Vector3 value);
void (*old_Teleport)(void *instance);
void Teleport(void *instance) {
if (instance != NULL) {
if (IsTeleport.x > 0 || IsTeleport.y > 0 || IsTeleport.z > 0) {
Teleport(instance, IsTeleport);
}
}
return old_Teleport(instance);
}


Teleport = (void (*)(void *, Vector3))getAbsoluteAddress("libil2cpp.so", 0x666F20);
A64HookFunction((void *)getAbsoluteAddress("libil2cpp.so", 0x666188), (void *)Teleport, (void **) &old_Teleport);


case 14:
IsTeleport = value;
break;
