Enemy Detection Area
I got an enemy that follows the player and explodes on impact (Creeper from MineCraft). Now the problem is that he follows the player as soon as the game starts, I want him to only follow the player when the player is close to him. I tried to use an invisible box for the detection area but it didn't work. I get no errors, and I get no "detected!" print.
var target : Transform;
var moveSpeed = 5;
var rotationSpeed = 5;
var myTransform : Transform;
var Detect : boolean = false;
function Awake()
{
myTransform = transform;
}
function Start()
{
target = GameObject.FindWithTag("Player").transform;
}
function OnTriggerEnter(other : Collider)
{
if (other.tag == "Player")
{
Detect = true;
print ("detected!");
}
}
function Update () {
if (Detect == true)
{
myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
}
}
also, If you got some other method I can use other than collision, please tell me.
Just compare your distance to the player distance each frame. If you want to be slightly more efficient, you can use distance squared.
function Update () {
if ((target.transform.positon - transform.position).sqrMagnitude < someDistanceSquared)
Detect = true;
if (Detect)
{
myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
}
}
Thanks for the method, but I still need a certain area, because if the Player is above the Enemy he will still be detected, I don't want that. Also I need the flexibility of the area box so I can make things like laser traps and such. So I will be happy if someone knows how to make the area box method work.
Usually this problem is caused by neither object having a rigidbody. Either the game object with the collider or the target has to have a Rigidbody.
if the Player is above the Enemy he will still be detected
I guess if he is on a different level.
You could use a linecast between the enemy and the player to check if there is any collider in between, if so it means the enemy cannot see the player.
