UnityEngine.Texture does not contain a definition for 'color'

I keep getting an UnityEngine.Texture does not contain a definition for 'color' error and a UnityEngine.Texture does not contain a definition for 'text' error for the lines in the startGame() and endGame() methods and i'm not sure how to fix it. I didn't see any errors pop up while he was typing the code in the video.

gameStateText.color = Color.clear; and gameStateText.color = Color.white; and gameStateText.text = "Game Over";

are the three problem lines, specifically the .color and .text part.

in the GameState script

using UnityEngine;
using System.Collections;
using UnityEngine.UI;


public class GameState : MonoBehaviour {

    private bool gameStarted = false;

    [SerializeField]
    private Texture gameStateText;

    [SerializeField]
    private GameObject player;

    [SerializeField]
    private BirdMovement birdMovement;

    [SerializeField]
    private FollowCamera followCamera;

    private float restartDelay = 3f;

    private float restartTimer;

    private PlayerMovement playerMovement;

    private PlayerHealth playerHealth;

    // Use this for initialization
    void Start () {
        Cursor.visible = false;

        playerMovement = player.GetComponent<PlayerMovement> ();
        playerHealth = player.GetComponent<PlayerHealth> ();

        // Prevent the player from moving at the start of the game
        playerMovement.enabled = false;

        //Prevent the bird from moving at the start of the game
        birdMovement.enabled = false;

        //Prevent the follow camera from moving to its game position
        followCamera.enabled = false;
    }


    // Update is called once per frame
    void Update () {
        // If the game is not started and the player presses the space bar...
        if(gameStarted == false && Input.GetKeyUp (KeyCode.Space)){

            //... start the game.
            StartGame();
        }
        // If the player is no longer alive...
        if(playerHealth.alive == false){
            //...end the game...
            EndGame();

            //...increment a timer to count up to restarting...
            restartTimer = restartTimer + Time.deltaTime;

            //...and if it reaches the restart delay...
            if(restartTimer >= restartDelay){

                //...then reload the currently loaded level.
                Application.LoadLevel(Application.loadedLevel);
            }
        }
    }

    private void StartGame(){
        //Set the game state
        gameStarted = true;

        //Remove the start text
        gameStateText.color = Color.clear;

        //Allow the player to move
        playerMovement.enabled = true;

        //Allow the bird to move
        birdMovement.enabled = true;

        //Allow the camera to move
        followCamera.enabled = true;
    }

    private void EndGame(){
        //Set the game state
        gameStarted = false;

        // Show the game over text
        gameStateText.color = Color.white;
        gameStateText.text = "Game Over";

        //Remove the player from the game
        player.SetActive (false);
    }
}

I just realized that monoDevelop autocorrect my variable

[SerializedField]
private Text gameStateText;

To:

[SerializedField]
private Texture gameStateText;

It's supposed to be a Text and not a Texture.

I'm glad you figured it out! Thanks for sharing the answer, too. :)

Oops yeah I did the same thing.
