GameObject.Find("...").GetComponent<Slider>(); Doesn't work?

[Aviation_Simmer]

Hi! I am working on the script, so it automaticly puts in the object it needs. It works fine for all eccept for theese two, which are marked and // I cant any tipping errors and I have rewrote them already a few times. no change. it always says:

NullReferenceException: Object reference not set to an instance of an object
AutoPilot.Awake () (at Assets/AutoPilot.cs:48)

NullReferenceException: Object reference not set to an instance of an object
AutoPilot.Awake () (at Assets/AutoPilot.cs: 52)

And yes I removed the //

You really should not be using GameObject.Find for hierarchies nested so deep. And honestly, you shouldn’t be using it at all.

Does all this live in the same scene? Can you not set up references to all of these objects in the inspector?

yes, It’s all in 1 scene. BUT its a llot of work and its way easier to make it this way 1 time instead of the other way in the inspectior like 20 times

And what if you change the hierarchy? Then you have to go through this nonsense again, dealing with the issues you are dealing with now.

It’s your time spent mate, but there’s a good reason why we can reference objects and components in the inspector.

Three steps to success:

• Identify what is null
• Identify why it is null
• Fix that
