Health UI Display

Question

I'm setting up the UI to the health code

 void OnGUI() {
         GUI.Label(new Rect(10, 10, 700, 40), "Health" + GetComponent<Health> Health);
 
     }

This is a separate script

 #pragma strict
 
 var MaxHealth = 100;
 var Health : int;
 
 function Start ()
 {
     Health = MaxHealth;
 }
 
 function ApplyDammage (TheDammage : int)
 {
     Health -= TheDammage;
     
     if(Health <= 0)
     {
         Dead();
     }
 }
 
 function Dead()
 {
     RespawnMenuV2.playerIsDead = true; //VERY IMPORTANT! This line was added in tutorial number 19. If you haven't reached that tutorial yet, go ahead and remove it.
     Debug.Log("Player Died");
 }
 
 function RespawnStats ()
 {
     Health = MaxHealth;
 }

But there's an error : error CS1525: Unexpected symbol `Health' How can I fix that?

You are missing a '.' in your GUI.Label before your variable Health. That line of code should be:

 GUI.Label(new Rect(10, 10, 700, 40), "Health" + gameObject.GetComponent<Health>().Health);

Also just to make sure, you do know you are using a JS script (Health Script) and a C# script (The one where you are displaying the Health).

And also its better to cache the component reference rather than using GetComponent() every single frame.

You can also add a GUIText, you should put this script onto your player, then put the Health text as a variable: Such as this

var HealthCounter : GUIText;

function OnGUI () { HealthCounter.text = "Health: " + Health.ToString(); }
