Can someone explain how this is done please? I'm trying to do melee combat for my game and I have animated my sword to swing. I've never used this before and have no idea how to implement it and the api isn't very helpful.

I have added an empty object and a box collider around the blade of the sword. I've added it as a child of the sword and have ticked Is Trigger. This is the script I have so far.

function OnTriggerEnter ( other : Collider )

{

    if ( other.tag == "Enemy" ) // or what ever you want to identify the object

    {

        other.GetComponent("EnemyHealth1").AdjustCurrentHealth(-10);

        Debug.Log("Enemy Hit!!");

    }

}

But it doesn't seem to be doing anything.

This is the script for the health and AdjustCurrentHealth

var hp:float; // health value, 0..maxHp

var maxHp:float; 

var healthBarWidth:int = 20;

var myHealthBar:GameObject;

private var myHb:GameObject;

var posX:float;

var posY:float;

var show: float = 0;       // health bar appears when show > 0

var duration: float = 0.6; // health bar vanishes for duration seconds



function Start () {

  myHb = Instantiate(myHealthBar, transform.position, transform.rotation);



}



function AdjustCurrentHealth(adj : int) {

   hp += adj;

}



function Update () {

  if (show>0){

    myHb.guiTexture.color.a = show; // variable show controls the bar alpha

    show -= Time.deltaTime/duration; // fades out health bar unless show is recharged

    myHb.transform.position = Camera.main.WorldToViewportPoint(transform.position);

    myHb.transform.position.x -= posX;

    myHb.transform.position.y -= posY;

  //  myHb.transform.localScale = Vector3.zero; // <- this does nothing

    var healthPercent:float = Mathf.Clamp(hp / maxHp, 0, 1);

    myHb.guiTexture.pixelInset = Rect (0.02, -0.09, healthBarWidth * healthPercent, 5);

  }

}

The health script is attached to my enemy and the melee attached the the empty game object with the box collider.
