var attack : int = 5;
var nextAttack : int = 0;

function Update () {

playerDist = Vector3.Distance(transform.position , player.position);

if(playerDist <= attackDist){

transform.LookAt(player);
animation.CrossFade (“attack”);

Attack();

return;

}

if(playerDist <= seekplayerDist){

transform.LookAt(player);
transform.position += transform.forward * speed * Time.deltaTime;
animation.CrossFade (“run”);

} else {

animation.CrossFade (“idle”);

}

}

function Attack (){

var attackRate : int = 5;
var nextAttack : int = 0;

attackStrenght = weaponDamage + strenght;
damage = (opponentAC) - (attackStrenght);
weaponDamage = Random.Range(1.0, 6.0);

if (Time.time > nextAttack) {

nextAttack = Time.time + attackRate;
//playerStats.health += damage;
}

Use Code tags…

I only found that you missed a } at the end.

Maybe seperate your { } on different lines if you have problems… I use this as habit now a days. Its easier to see what bracket matches the other.

Example:

public class MyClass
{
	public void SomeMethod()
	{
		if(IsSomethingHappening())
		{
			//Do something
		}
	}

	private bool IsSomethingHappening()
	{
		return true;
	}
}

var attack : int = 5;
var nextAttack : int = 0;

function Update () {
	playerDist = Vector3.Distance(transform.position , player.position);

	if(playerDist <= attackDist) {
		transform.LookAt(player);
		animation.CrossFade ("attack");
		Attack();
		return;
	}

	if(playerDist <= seekplayerDist) {
		transform.LookAt(player);
		transform.position += transform.forward * speed * Time.deltaTime;
		animation.CrossFade ("run");
	} else {
		animation.CrossFade ("idle");
	}
}


function Attack () {
	var attackRate : int = 5;
	var nextAttack : int = 0;

	attackStrength = weaponDamage + attackStrength;
	damage = (opponentAC) - (attackStrength);
	weaponDamage = Random.Range(1.0f, 6.0f);

	if (Time.time > nextAttack) {

		nextAttack = Time.time + attackRate;
		//playerStats.health += damage;
	}
} // <--- You missed this bracket.

Hi ks9109,

You are missing a } at the end of your script.

The last } is closing the if statement, and Attack() is left open.

ks9109,

It’s hard to provide help without seeing the full code, but those errors are because you don’t have the variables defined within their relative scope.

when you say that you mean like

var player
var attackDist
etc…
right Ezro

}

}
