My game is a 2D RTS, and I was wondering if anyone knew of a good tutorial for Unity, or if someone well-versed in the syntax of it could tell me what I could have done wrong.

So, I have my camera object, and my player object, both tagged. The player object just has a sprite on it, and is set to rigidbody. The script goes as follows:

using UnityEngine;
using System.Collections;

public class AIsciript : MonoBehaviour
{
private bool thisIsPlayer = true;
private GameObject objPlayer;
private GameObject objCamera;

//input variables (variables used to process and handle input)
private Vector3 inputRotation;
private Vector3 inputMovement;

//identity variables (variables specific to the game object)
public float moveSpeed = 100f;

// calculation variables (variables used for calculation)
private Vector3 tempVector;
private Vector3 tempVector2;

// Use this for initialization
void Start()
{
    objPlayer = (GameObject)GameObject.FindWithTag("Player");
    objCamera = (GameObject)GameObject.FindWithTag("MainCamera");
    if (gameObject.tag == "Player")
    {
        thisIsPlayer = true;
    }
}

// Update is called once per frame
void Update()
{
    FindInput();
    ProcessMovement();
    if (thisIsPlayer == true)
    {
        HandleCamera();
    }
}

void FindInput()
{
    if (thisIsPlayer == true)
    {
        FindPlayerInput();
    }
    else
    {
        FindAIInput();
    }
}
void FindPlayerInput()
{
    //find vector to move
    inputMovement = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

    //find vector to the mouse
    tempVector2 = new Vector3(Screen.width * 0.5f, 0, Screen.height * 0.5f);

    // the position of the middle of the screen
    tempVector = Input.mousePosition;

    // find the position of the mouse on screen
    tempVector.z = tempVector.y;

    tempVector.y = 0;
    Debug.Log(tempVector);
    inputRotation = tempVector - tempVector2;
}
void FindAIInput()
{

}
void ProcessMovement()
{
    rigidbody.AddForce(inputMovement.normalized * moveSpeed * Time.deltaTime);
    objPlayer.transform.rotation = Quaternion.LookRotation(inputRotation);
    objPlayer.transform.eulerAngles = new Vector3(0, transform.eulerAngles.y + 180, 0);
    objPlayer.transform.position = new Vector3(transform.position.x, 0, transform.position.z);
}
void HandleCamera()
{
    objCamera.transform.position = new Vector3(transform.position.x, 15, transform.position.z);
    objCamera.transform.eulerAngles = new Vector3(90, 0, 0);
}
}

I just figured I would post the code just in case, but I figure it's probably not the issue, as I tried to force it to move in Start() and nothing happened.
