Lerp coroutine not executing

Questions & Answers

I’m trying to slide an element to a new position. When ‘changeState’ executes, it starts the ‘elementSlide’ coroutine, but nothing happens. I’ve tried writing the coroutine a few different ways, but have ended up with the same problem.

using UnityEngine;
using System.Collections;

public class MindManager : MonoBehaviour {

	//Variable to determine if the layer is active
	public bool currentlyActive = true;

	//Variable to determine if the layer is available
	public bool currentlyAvailable = true;

	//
	[System.Serializable]
	public struct bgPosScale
	{
		public float xpos;
		public float ypos;
		public float scaleFactor;
	}

	public bgPosScale[] bgOffset = new bgPosScale[3]; 

	public GameObject bgTarget;
	public float bgScale;
	public float transTime = 100f;

	//Enumerate the subsections of the Mind layer
	public enum SUBSTATE : int {TOP =0, HEAD = 1, LEFT = 2, RIGHT = 3,};

	public SUBSTATE subState = SUBSTATE.TOP;

	public void Start()
	{

	}

	public void changeState(int toState)
	{

		if (toState != (int)subState) //Only transition if state is not currently active
		{
			Vector3 startPos = bgTarget.transform.position;//Store BG element's current position
			Vector3 newPos = new Vector3(bgOffset[toState].xpos, bgOffset[toState].ypos,0);//Grab the desired position

			subState = (SUBSTATE)toState; //Set desired state to active state

			elementSlide(bgTarget, startPos, newPos, transTime); //Initiate coroutine


			//bgTarget.transform.position = new Vector3 (bgOffset[toState].xpos, bgOffset[toState].ypos,0);
			//bgTarget.transform.localScale = new Vector3(bgScale*bgOffset[toState].scaleFactor,bgScale*bgOffset[toState].scaleFactor,0);
		}
	
	}

	public IEnumerator elementSlide (GameObject target, Vector3 startPos, Vector3 newPos, float time)
	{
		float timePassed = 0f;

		while (timePassed < time) {
			target.transform.position = Vector3.Lerp (startPos, newPos, (timePassed / time));
			timePassed += Time.deltaTime;
			yield return null;
		}
	}

You start a coroutine using StartCoroutine, so:

StartCoroutine(elementSlide(bgTarget, startPos, newPos, transTime));
