Making AI attack (My Script Attached)

Questions & Answers
1

Hello I’m trying to make my AI attack me and take damage off me. My script is below. Where would I begin in making this happen.

EnemyAtk.js

var giveUpThreshold = 20; // distance beyond which AI gives up
var attackRepeatTime = 1; // delay between attacks when within range
 
private var chasing = false;
private var attackTime = Time.time;
 
var myTransform : Transform; //current transform data of this enemy
 
function Awake()
{
    myTransform = transform; //cache transform data for easy access/preformance
}
 
function Start()
{
     target = GameObject.FindWithTag("Player").transform; //target the player
}
 
function Update () {
 
    // check distance to target every frame:
    var distance = (target.position - myTransform.position).magnitude;
 
    if (chasing) {
 
        //rotate to look at the player
        myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
        Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
 
        //move towards the player
        myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
 
        // give up, if too far away from target:
        if (distance > giveUpThreshold) {
            chasing = false;
        }
 
        // attack, if close enough, and if time is OK:
        if (distance < attackThreshold && Time.time > attackTime) {
            // Attack! (call whatever attack function you like here)

            attackTime = Time.time + attackRepeatTime;
        }
   
    } 
    
    else {
        // not currently chasing.
 
        // start chasing if target comes close enough
        if (distance < chaseThreshold) {
            chasing = true;
        }
    }
}

and my player Health Script is attached below.

// JavaScript
var enemyHealth : int = 100;
var backgroundTexture : Texture;
var foregroundTexture : Texture;
var frameTexture : Texture;

var healthWidth: int = 199;
var healthHeight: int = 30;

var healthMarginLeft: int = 41;
var healthMarginTop: int = 38;

var frameWidth : int = 266;
var frameHeight: int = 65;

var frameMarginLeft : int = 10;
var frameMarginTop: int = 10;

function OnGUI () {

    GUI.DrawTexture( Rect(frameMarginLeft,frameMarginTop, frameMarginLeft + frameWidth, frameMarginTop + frameHeight), backgroundTexture, ScaleMode.ScaleToFit, true, 0 );
    
    GUI.DrawTexture( Rect(healthMarginLeft,healthMarginTop,healthWidth + healthMarginLeft, healthHeight), foregroundTexture, ScaleMode.ScaleAndCrop, true, 0 );
    
    GUI.DrawTexture( Rect(frameMarginLeft,frameMarginTop, frameMarginLeft + frameWidth,frameMarginTop + frameHeight), frameTexture, ScaleMode.ScaleToFit, true, 0 );

}

I was thinking of adding something to do with the collision to the enemy’s attack script but I’ve only just started learning coding and not sure about how I would code it, I know the idea of what I want to do like Collision>Enemy=attack>player health goes down -3 but how would I make that happen and what sort of tutorial will help me?

Google/YouTube BurgZergArcade hack and slash.

Try changing this

// Attack! (call whatever attack function you like here)

to something like this

pcvitals = target.GameObject.GetComponent<Player_Vitals>();
pcvitals.AdjustCurHealth(5);

where you have a Class called Player_Vitals attached to your player that has fuction AdjustCurHealth that takes an integer and reduces player health. This is just an example. Get that working and then expand it to include animations, game state mechanic checks (like mobIsNotStunned, mobIsNotDisarmed, etc).
