Setting An AI Routine
Hey, Guys!
So, I'm Learning Unity, so I'm having a hard time.
You know, I'm trying to program a simple rotine for my enemy bots, it's like this.
If the enemy doesn't spot the enemy, he'll just walk in a point a, then to the point b, just patroling, thinking about his robot life.
He'll walk to the point A, wait for 3 seconds, go to the point B, wait for more 3 seconds, back to the point A, and so on.
And if he's seeing the player, he'll pursuit him.
Anyway, i'm using NavMesh, to try to make that big boy walk around.
I just don't have a clue how to script this, could you help me?
Sorry for my english, I'm from Brazil
Put this on your Bot, create some empty gameobjects for you waypoints, however many you want, fill in the fields in the inspector, make sure you Bot has a character controller on it, then move your player towards the Bot and he, or she should attack .. Not tested ..
Hope this helps.
#pragma strict
var waypoint : Transform[]; // The amount of Waypoint you want
var patrolSpeed : float = 3; // The walking speed between Waypoints
var loop : boolean = true; // Do you want to keep repeating the Waypoints
var player : Transform; // Referance to the Player
var dampingLook = 6.0; // How slowly to turn
var pauseDuration : float = 0; // How long to pause at a Waypoint
var attackRange = 10; // Range to start the attack
var attackSpeed = 5.0; // Speed to attack
var attackLook = 10.0; // How fast to turn when attacking
private var distanceToPlayer : int; // Distance from the enemy to the Player
private var curTime : float;
private var currentWaypoint : int = 0;
private var character : CharacterController;
private var gravity : float = 2.0;
private var attacking : boolean = false;
function Awake(){
}
function Start(){
character = GetComponent(CharacterController);
}
function Update(){
distanceToPlayer = Vector3.Distance(player.position, transform.position); // Distance between the enemy and the Player
if(distanceToPlayer < attackRange){
attacking = true;
attack();
}else{
attacking = false;
}
if(currentWaypoint < waypoint.length && !attacking){
patrol();
}else{
if(loop && !attacking){
currentWaypoint=0;
}
}
}
function patrol(){
var target : Vector3 = waypoint[currentWaypoint].position;
target.y = transform.position.y; // Keep waypoint at character's height
var moveDirection : Vector3 = target - transform.position;
if(moveDirection.magnitude < 0.5){
if (curTime == 0)
curTime = Time.time; // Pause over the Waypoint
if ((Time.time - curTime) >= pauseDuration){
currentWaypoint++;
curTime = 0;
}
}else{
// Look at and dampen the rotation
var rotation = Quaternion.LookRotation(target - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * dampingLook);
character.Move(moveDirection.normalized * patrolSpeed * Time.deltaTime);
}
}
function attack(){
// Attack the Player
// Rotate to face the Player
var lookPos = player.position - transform.position;
lookPos.y = 0;
var rotation = Quaternion.LookRotation(lookPos);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * attackLook);
// Move towards the Player
var target : Vector3 = player.position;
var moveDirection : Vector3 = target - transform.position;
moveDirection.y = 0; // Stop the character running up off the floor to match the Players Y axis
moveDirection.y -= gravity; // Add gravity so the he always stays on the ground
character.Move(moveDirection.normalized * attackSpeed * Time.deltaTime);
}
I've tested that, is working well, but, it's not facing the target, in that case, the waypoints
Thanks for the help, It's working ok, but, I'm having problems about collisions. I've attached a Sphere collider in the bot's sword, then, if that sphere collides with the player, then the player loses a point of HP, but the collision is not working, and I Hell don't know why!!
that's the AI script so far:
var waypoint : Transform[]; // The amount of Waypoint you want
var patrolSpeed : float = 3; // The walking speed between Waypoints
var loop : boolean = true; // Do you want to keep repeating the Waypoints
var player : Transform; // Referance to the Player
var dampingLook = 6.0; // How slowly to turn
var pauseDuration : float = 0; // How long to pause at a Waypoint
var attackRange = 10; // Range to start the attack
var attackSpeed = 5.0; // Speed to attack
var attackLook = 10.0; // How fast to turn when attacking
var AtkSpeed = 1;
private var distanceToPlayer : int; // Distance from the enemy to the Player
private var curTime : float;
private var currentWaypoint : int = 0;
private var character : CharacterController;
private var gravity : float = 2.0;
private var attacking : boolean = false;
private var isattacking : boolean = false;
function Awake(){
}
function Start(){
character = GetComponent(CharacterController);
animation["attack"].speed = AtkSpeed;
animation["attack"].layer = 1;
}
function Update(){
distanceToPlayer = Vector3.Distance(player.position, transform.position); // Distance between the enemy and the Player
if(distanceToPlayer < attackRange){
attacking = true;
attack();
}else{
attacking = false;
}
if(currentWaypoint < waypoint.length && !attacking){
patrol();
}else{
if(loop && !attacking){
currentWaypoint=0;
}
}
}
function patrol(){
var target : Vector3 = waypoint[currentWaypoint].position;
target.y = transform.position.y; // Keep waypoint at character's height
var moveDirection : Vector3 = target - transform.position;
if(moveDirection.magnitude < 0.5){
if (curTime == 0) {
curTime = Time.time; // Pause over the Waypoint
animation.Play("idle");
}
if ((Time.time - curTime) >= pauseDuration){
currentWaypoint++;
curTime = 0;
}
}else{
// Look at and dampen the rotation
var rotation = Quaternion.LookRotation(target - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * dampingLook);
character.Move(moveDirection.normalized * patrolSpeed * Time.deltaTime);
animation.Play("walk");
}
}
function attack(){
// Attack the Player
if (distanceToPlayer <= 1) {
animation.Play("attack");
}
else {
animation.Stop("attack");
}
// Rotate to face the Player
var lookPos = player.position - transform.position;
lookPos.y = 0;
var rotation = Quaternion.LookRotation(lookPos);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * attackLook);
// Move towards the Player
var target : Vector3 = player.position;
var moveDirection : Vector3 = target - transform.position;
moveDirection.y = 0; // Stop the character running up off the floor to match the Players Y axis
moveDirection.y -= gravity; // Add gravity so the he always stays on the ground
character.Move(moveDirection.normalized * attackSpeed * Time.deltaTime);
animation.Play("run");
}
And that's is the script that I've made for the sphere collider:
var Life = 3;
function OnCollisionEnter(theCollision : Collision){
if(theCollision.gameObject.tag=="Player") {
Life -= 1;
}
}
function Update () {
print ("Health :" +Life); }
I'm really having problems to learn about collisions and triggers =/
