Moving a GameObject (camera) forward and backward along a series of points (C#).

Questions & Answers

Hello Answerers!

N.B. I am a noob at scripting & coding, my sincerest apologies.

I have a series of locations that I have specified with gameobjects, I have a simple system whereby I move the camera to a specific location thus:

using UnityEngine;
using System.Collections;

public class MoveCameraTo1 : MonoBehaviour {

	void OnMouseDown() {
		Camera.main.transform.position = GameObject.Find("pos1").transform.position;
		Debug.Log("we're going to Pos1!");
	}

However, I would also like to move the camera forward or backward along this series (formed of pos1,2,3 etc.). Should I be using an array or list, or way-points or something of that nature? I have also seen scripts that try to find the closest object of a type, but seeing as these points will be equally spaced, I think that would be more troublesome, wouldn’t it?

Thanks in advance to anyone who can help!

EDIT!
I have been trying to use this, setting the positions to enemies:

using UnityEngine;
using System.Collections;

public class Get : MonoBehaviour {
	Transform GetClosestEnemy(Transform[] enemies)
    {
        Transform tMin = null;
        float minDist = Mathf.Infinity;
        Vector3 currentPos = transform.position;
        foreach (Transform t in enemies)
        {
            float dist = Vector3.Distance(t.position, currentPos);
            if (dist < minDist)
            {
                tMin = t;
                minDist = dist;
            }
        }
        return tMin;
    }
	void OnMouseDown() {
		Camera.main.transform.position = Get.transform.position;
		Debug.Log("we're going forward!");

}}

But I have likely borked it up; I dont know what tMin is or how to refer to Get in my OnMouseDown function (is it even a function? I just don’t know anymore).

EDIT2!
Here is the functional code I spliced:

Transform[] pointlist = new Transform[3];

void Start()
{
    for (int n=0; n < pointlist.Length; ++n)
    {
        pointlist[n] = GameObject.Find("pos"+(n+1)).transform;
    }
}
Transform GetPoint(Transform[] Places)
{
    Transform tMin = null;
    float minDist = Mathf.Infinity;
    Vector3 currentPos = transform.position;
    foreach (Transform t in pointlist)
    {
        float dist = Vector3.Distance(t.position, currentPos);
        if (dist < minDist)
        {
            tMin = t;
            minDist = dist;
        }
    }
    return tMin;
}
void OnMouseDown() {
	Camera.main.transform.position = GetPoint(pointlist).position;
	Debug.Log("We're going forward!");

}

You don’t need to refer to the class name since you’re already in a method of the class. You just have to call the GetClosestEnemy function and get the position out of the transform it returns. I guess first you have to get an array of enemy transforms to pick one from. You can do this either by having a public field in your Get class that is a Transform array that you could assign transforms to in the editor or you could get them programmatically from the scene using GameObject.FindGameObjectsWithTag or something like that and then either change the GetClosestEnemy function to accomodate an array of GameObjects instead of Transforms or convert the array to one of Transforms. After you have the array of transforms you call the function like:

Camera.main.transform.position = GetClosestEnemy(ENEMIES_ARRAY_GOES_HERE).position;
