ERROR, playerMovement is a TYPE but variable is expected ?

don't know why I'm getting this error

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class GameState : MonoBehaviour {

private bool gameStarted = false; 
[SerializeField]
private Text gameStateText;
[SerializeField]
private GameObject player;
[SerializeField]
private BirdMovement birdMovement;
[SerializeField]
private FollowCamara followCamera;
private float restarDelay = 3f;
private float restartTimer;

// HAS TO DO WITH THIS VARAIBLE PLAYERMOVEMNT.//////////////////////////////////////////// private PlayerMovement playerMovement ; private PlayerHealth playerHealth;

// Use this for initialization
void Start () {
    Cursor.visible = false;
    PlayerMovement = player.GetComponent<PlayerMovement> ();
    PlayerHealth = player.GetComponent<PlayerHealth> ();

    // prevent th epalyer from moving at the sart of the game 
    playerMovement.enabled = false;
    birdMovement.enabled = false;
    followCamera.enabled = false;


}

// Update is called once per frame
void Update () {
    // if game not stared and keysAPCE IS PRESS UP 
    if (gameStarted == false && Input.GetKeyUp (KeyCode.Space)) {

        StartGame();

    }

    if (playerHealth.alive == false) {
        // end the game...

        EndGame();

        // incremt a timer p trestaring
        restartTimer = restartTimer + Time.deltaTime;

        // .. and if reaches the restat delay...
        if (restartTimer >= restarDelay) {

                //...then reload the currently loaded level.
                SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        }

    }
}

private void StartGame() {
    gameStarted = true;
    gameStateText.color = Color.clear;
    playerMovement.enabled = true;
    birdMovement.enabled = true;
    followCamera.enabled = true;
}
private void EndGame() {
    gameStarted = false;

    gameStateText.color = Color.white;
    gameStateText.text = "Game Over!";

    player.SetActive (false);
}

You have some problems your code should look like this:

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

public class GameState : MonoBehaviour {

private bool gameStarted =  false;
[SerializeField]
private Text 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>();
    playerMovement.enabled = false;
    birdMovement.enabled = false;
    followCamera.enabled = false;

}

// Update is called once per frame
void Update () {
    if (gameStarted == false && Input.GetKeyUp (KeyCode.Space))
    {
        StartGame();
    }
    if (playerHealth.alive == false)
    {
        EndGame();
        restartTimer = restartTimer + Time.deltaTime;

        if (restartTimer >= restartDelay)
        {
            SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
        }
    }
}

private void StartGame() {

    gameStarted = true;
    gameStateText.color = Color.clear;
    playerMovement.enabled = true;
    birdMovement.enabled = true;
    followCamera.enabled = true;  //This line is missing entirely from your code
}
private void EndGame()
{
    gameStarted = false;

    gameStateText.color = Color.white;

    gameStateText.text = "Game Over!";
    player.SetActive(false);
}

}

When you are assigning the PlayerMovement and the PlayerHealth components to the playerMovement and playerHealth variables in the Start () method, you are capitalizing the variables.
