Get object name from raycast.

Question

Hey. I'm trying to get a gameobject's name using raycast, and set it to a var. But exexuting the code give me the error "(11,41): BCE0034: Expressions in statements must only be executed for their side-effects."

Heres my code.

public var myNewTexture2D:Texture2D;

function Update () { if ( Input.GetMouseButtonDown(1) ) { var hit : RaycastHit; var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition); if (Physics.Raycast (ray, hit, 100.0)) { hit.collider.gameObject.name; //RaycastHit.collider; renderer.material.mainTexture = myNewTexture2D; renderer.material.SetColor ("_SpecColor", Color.red); Debug.Log(hit.collider.gameObject.name); } } }

hit.collider.gameObject.name;

Just putting a variable on a line by itself generates that error.

You need to assign something to it or assign it to something. :)

Or, just get rid of that line - you are already printing it out a few lines later. Looks like it was just a cut-and-paste error.
