please fixed
it would be very helpful if you could format your code nicely.
I agree with phodges. Use the necessary time to make your question representable

As mentioned elsewhere, try adding a few null checks around objects. For example, in Start, don't just dereference go.transform but check that go is not null first. If it turns out to be then you could also add a Debug.Log as a warning. Similarly. in Update, you can always check if 'taikinys' is null and return early if it is.
