C# Coding - Game Fix

We have this code, which is code of a game. It has been written in C# using Unity 3D. Requirements: 1) Fix Code in order to run game successfully 2) Display "GAME OVER" when Ball (Game object) falls below Y-value of " -4" . 3) Show Button for Restart Game. --- Its a very basic fix, so we have a One-hour budget. using UnityEngine; using [login to view URL]; public class playerScript : MonoBehaviour { public float speed; //do I need this line? public GUIText countText; public GUIText winText; private int count; public GUIText restartText; public GUIText gameOverText; private bool gameOver; // THIS LINE OF CODE HAS BEEN RECENTLY ADD private bool restart; // THIS LINE OF CODE HAS BEEN RECENTLY ADD void Start () { gameOver = false;// THIS LINE OF CODE HAS BEEN RECENTLY ADD restart = false;// THIS LINE OF CODE HAS BEEN RECENTLY ADD [login to view URL] = "";// THIS LINE OF CODE HAS BEEN RECENTLY ADD [login to view URL] = ""; //text will not show at the beggining of the game. count = 0; setCountText (); [login to view URL] = ""; [login to view URL] = ""; } /*void Update () // This is code added. { // This is code added. if (restart) { // This is code added. // This is code added. if ([login to view URL] (KeyCode.R) // This is code added. { [login to view URL] ([login to view URL]);// This line of code restarts the game. } } } public void GameOver () // THIS LINE OF CODE HAS BEEN RECENTLY ADD { [login to view URL] = "GameOver!"; // THIS LINE OF CODE HAS BEEN RECENTLY ADD gameOver = true; // THIS LINE OF CODE HAS BEEN RECENTLY ADD }// THIS LINE OF CODE HAS BEEN RECENTLY ADD */ void FixedUpdate () { float moveHorizontal = [login to view URL]("Horizontal"); float moveVertical = [login to view URL] ("Vertical"); Vector3 movement =new Vector3(moveHorizontal, 0.0f, moveVertical); [login to view URL](movement); } void OnTriggerEnter(Collider other) { if ([login to view URL] == "pickUp") { [login to view URL] (false); count = count + 1; setCountText (); } } void setCountText () { [login to view URL] = "Count: " + [login to view URL](); if (count >= 35) [login to view URL] = "You Win!"; GameObject player = [login to view URL]("player"); if([login to view URL]>=-1) [login to view URL] = "You lose!"; } /*void update(){ float y; GameObject player = [login to view URL]("player"); if(count==1) { //[login to view URL] = "game over!"; //player.transform.position.y<-1 } }*/ }
