It means that the GetComponent is returning null. This most likely means that the Seeker script was not added to the object.

If you are trying to add a Seeker script programmatically, use AddComponent

this was correct for some reason the prefab with the seeker component wasnt added to the ones already in the scene.

Thank you

Answer by sparkzbarca · Nov 20, 2012 at 12:38 AM

Which line is the error on?

Could be one of two things

A. There isn't a Seeker Component attached to the gameObject this script is attached to so seeker isn't equal to anything

B closest which i can see is in here but not what it is may not be equal to anything

Fix A by adding a Seeker Component you could even use a RequireComponent Seeker in the gameObject code so it throws an error if a seeker isnt attached.

fix B by having closests actually equal something
