"Identifier Expected" error?

Question

using UnityEngine;
using System.Collections;

public class Sword : MonoBehaviour {

var totalhealth = 100;

    function OnTriggerEnter(other : Collider){
        if(other.tag == "angelic_sword_02"){
            totalhealth -= 50;
        }
    }

    function Update(){
        if(totalhealth <= 0){
            Destroy(gameObject);
        }
    }
}

I get an "Identifier Expected" in the script where it says in the line

function OnTriggerEnter(other : Collider) {

Any help please?

@JeroenVannevel: It's partially C#. Unity supports multiple extension languages. It looks like code from two examples, using two languages, mixed together. — Eric J., May 08 '15 at 01:24
@EricJ. I see, some bastard child of C# then. Is `var` allowed to define a field? — Jeroen Vannevel, May 08 '15 at 01:25
It's C# compiled with Mono. Not sure which version of C# is supported. — Eric J., May 08 '15 at 01:31

You are using incorrect syntax for a C# method. Unity supports multiple languages for user code. Perhaps you copied an example from a different language?

function OnTriggerEnter(other : Collider){
    if(other.tag == "angelic_sword_02"){
        totalhealth -= 50;
    }
}

Should be closer to

public void OnTriggerEnter(Collider other){
    if(other.tag == "angelic_sword_02"){
        totalhealth -= 50;
    }
}

Thank you! That helped me out, and I guess I'm not that good at scripting yet, and I'm still studying both C# and Javascript, so I tend to mix both of them up. But now I'm getting a new error for "var". I forgot what you put there instead. I know it's not "function" because that's Javascript.... right? You put "void' instead...right? – thebandgeekgamer May 08 '15 at 01:35

We all start somewhere. It does look a lot like JavaScript. Just change `var` to `int`. – Eric J. May 08 '15 at 01:37

I finally figured it out. And I have no more compiler errors anymore.

using UnityEngine;
using System.Collections;

public class Sword : MonoBehaviour {

public float totalhealth = 100;

public void OnTriggerEnter(Collider other){
    if(other.tag == "angelic_sword_02"){
        totalhealth -= 50;
    }
}

void Update(){
    if(totalhealth <= 0){
        Destroy(gameObject);
    }
}
}

@EricJ thank you for helping me out. :)
