Hi everyone, I got a little issue with an enemy I recently created. Im using almost the same code that I use for my other enemies, but this one seems not to be working, cuz I cannot damage the enemy.
Here is the code
var speed = 3.0;
var rotationSpeed = 5.0;
var shootRange = 15.0;
var attackRange = 30.0;
var shootAngle = 4.0;
var dontComeCloserRange = 5.0;
var delayShootTime = 0.35;
var pickNextWaypointDistance = 2.0;
var target : Transform;
public var health=100;
private var lastShot = -10.0;
// Make sure there is always a character controller
@script RequireComponent (CharacterController)
function Start () {
// Auto setup player as target through tags
if (target == null GameObject.FindWithTag("Player"))
target = GameObject.FindWithTag("Player").transform;
Patrol();
}
function Update(){
if(health<=0)
Dead();
}
function Patrol ()
{
var curWayPoint = AutoWayPoint.FindClosest(transform.position);
while (true)
{
var waypointPosition = curWayPoint.transform.position;
// Are we close to a waypoint? -> pick the next one!
if (Vector3.Distance(waypointPosition, transform.position) < pickNextWaypointDistance)
curWayPoint = PickNextWaypoint (curWayPoint);
// Attack the player and wait until
// - player is killed
// - player is out of sight
if (CanSeeTarget ())
yield StartCoroutine("AttackPlayer");
// Move towards our target
MoveTowards(waypointPosition);
yield;
}
}
function CanSeeTarget () : boolean
{
if (Vector3.Distance(transform.position, target.position) > attackRange)
return false;
var hit : RaycastHit;
if (Physics.Linecast (transform.position, target.position, hit))
return hit.transform == target;
return false;
}
function Shoot ()
{
// Start shoot animation
animation.CrossFade("Explotion", 0.3);
// Wait until half the animation has played
yield WaitForSeconds(delayShootTime);
// Fire gun
// BroadcastMessage("Fire");
// Wait for the rest of the animation to finish
yield WaitForSeconds(animation["Explotion"].length - delayShootTime);
}
function AttackPlayer ()
{
var lastVisiblePlayerPosition = target.position;
while (true)
{
if (CanSeeTarget ())
{
// Target is dead - stop hunting
if (target == null)
return;
// Target is too far away - give up
var distance = Vector3.Distance(transform.position, target.position);
if (distance > shootRange * 3)
return;
lastVisiblePlayerPosition = target.position;
if (distance > dontComeCloserRange)
MoveTowards (lastVisiblePlayerPosition);
else
RotateTowards(lastVisiblePlayerPosition);
var forward = transform.TransformDirection(Vector3.forward);
var targetDirection = lastVisiblePlayerPosition - transform.position;
targetDirection.y = 0;
var angle = Vector3.Angle(targetDirection, forward);
// Start shooting if close and play is in sight
if (distance < shootRange angle < shootAngle)
yield StartCoroutine("Shoot");
}
else
{
yield StartCoroutine("SearchPlayer", lastVisiblePlayerPosition);
// Player not visible anymore - stop attacking
if (!CanSeeTarget ())
return;
}
yield;
}
}
function SearchPlayer (position : Vector3)
{
// Run towards the player but after 3 seconds timeout and go back to Patroling
var timeout = 3.0;
while (timeout > 0.0)
{
MoveTowards(position);
// We found the player
if (CanSeeTarget ())
return;
timeout -= Time.deltaTime;
yield;
}
}
function RotateTowards (position : Vector3)
{
SendMessage("SetSpeed", 0.0);
var direction = position - transform.position;
direction.y = 0;
if (direction.magnitude < 0.1)
return;
// Rotate towards the target
transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(direction), rotationSpeed * Time.deltaTime);
transform.eulerAngles = Vector3(0, transform.eulerAngles.y, 0);
}
function MoveTowards (position : Vector3)
{
var direction = position - transform.position;
direction.y = 0;
if (direction.magnitude < 0.5)
{
SendMessage("SetSpeed", 0.0);
return;
}
// Rotate towards the target
transform.rotation = Quaternion.Slerp (transform.rotation, Quaternion.LookRotation(direction), rotationSpeed * Time.deltaTime);
transform.eulerAngles = Vector3(0, transform.eulerAngles.y, 0);
// Modify speed so we slow down when we are not facing the target
var forward = transform.TransformDirection(Vector3.forward);
var speedModifier = Vector3.Dot(forward, direction.normalized);
speedModifier = Mathf.Clamp01(speedModifier);
// Move the character
direction = forward * speed * speedModifier;
GetComponent (CharacterController).SimpleMove(direction);
SendMessage("SetSpeed", speed * speedModifier, SendMessageOptions.DontRequireReceiver);
}
function Damage(damage:float){
health-=damage;
}
function Dead(){
Destroy (gameObject, 1);
}
function PickNextWaypoint (currentWaypoint : AutoWayPoint)
{
// We want to find the waypoint where the character has to turn the least
// The direction in which we are walking
var forward = transform.TransformDirection(Vector3.forward);
// The closer two vectors, the larger the dot product will be.
var best = currentWaypoint;
var bestDot = -10.0;
for (var cur : AutoWayPoint in currentWaypoint.connected)
{
var direction = Vector3.Normalize(cur.transform.position - transform.position);
var dot = Vector3.Dot(direction, forward);
if (dot > bestDot cur != currentWaypoint)
{
bestDot = dot;
best = cur;
}
}
return best;
}
And here’s the function that deals the damage
var beenHit=false;
function OnTriggerEnter (hit :Collider){
if (hit.gameObject.tag=="Sword"&beenHit==false){
beenHit=true;
gameObject.SendMessageUpwards("Damage",25);
yield WaitForSeconds(0.4);
beenHit=false;
}
For some reason, I cannot understand, the variable beenHit never enables, but with the same script in the other enemies, I got no issue.
Why could this be happening?
