Question

I need help with some health code:

 var maxHealth : int = 100;
 var currentHealth : int = 100;
 function Update () {
     if(currentHealth < 0) {
         currentHealth = 0;
     }
     if(currentHealth > maxHealth) {
         currentHealth = 0;
     }
     if(maxHeath < 1) {
         maxHealth = 1;
     }
     if(currentHealth < 0) {
         Application.LoadLevel ("Gameover");
     }
 }
 function OnGUI() {
     if(GUI.Button ( Rect ( 150, 10, 100, 35) , "Health")) 
 }
 To me: it looks fine To Unity: 2 errors
 The errors are:
 Assets/PlayerHealth.js(19,1): BCE0044: expecting }, found ''.
 Assets/PlayerHealth.js(18,63): BCE0043: Unexpected token: }.

Help please?

You aren't doing anything after that if(GUI.Button... !! You need something to happen in response to the if condition - or if you don't care and just want a button on screen drop the if( and add a ; on the end.

 function OnGUI() {
     if(GUI.Button ( Rect ( 150, 10, 100, 35) , "Health"))  {
         //Do something if the button is pressed
     }
 }

i have a script you could use, except it doesnt have game over:

 using UnityEngine;
     using System.Collections;
     
     public class PlayerHealth : MonoBehaviour {
             public int maxHealth = 100;
             public int curHealth = 100;
         
             public float healthBarLength;
     
         // Use this for initialization
         void Start () {
             healthBarLength = Screen.width / 2;
         }
         
         // Update is called once per frame
         void Update () {
             AddjustCurrentHealth(0);
         }
         
         void OnGUI() {
             GUI.Box(new Rect(10, 10, healthBarLength, 20), curHealth + "/" + maxHealth);
         }
         
         public void AddjustCurrentHealth(int adj) {
             curHealth += adj;
             
             if(curHealth < 1)
                 curHealth = 1;
             
             if(curHealth > maxHealth)
                 curHealth = maxHealth;
             
             if(maxHealth < 1)
                 maxHealth = 1;
             
             healthBarLength = (Screen.width / 2) * (curHealth / (float)maxHealth);
         }
     }
