enemy spawning when dead
i am using the fps tutorial AI script. i whant to spawn the robot back after a certan amount of time how can i do it?
fps tutorial AI : 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;
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 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("shoot", 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["shoot"].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 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;
}
