Enemy Collisions

Questions & Answers
1

I created an enemy script to move towards the player when in range. However, when i try colliding with the enemy, the character controller (player) goes right through the enemy as if there is no collider on the enemy. I have a feeling the transform.Translate is causing this problem. Is their a better way of moving the enemy toward the player, or a way to fix this collision problem?

var lookAtTarget : Transform;

var runningspeed : int;

var range : int;

var damp : float;

var disable = true;



function Awake()

{

	if (!lookAtTarget)

	{

		lookAtTarget = GameObject.FindWithTag("Player").transform;

		ENEMY_HEALTH = 10;

	}

}



function Update() 

{	

if(lookAtTarget && CanAttackTarget())

	{

		var rotate = Quaternion.LookRotation(lookAtTarget.transform.position - transform.position);

		transform.rotation = Quaternion.Slerp(transform.rotation, rotate, Time.deltaTime * damp); 

		transform.Translate (0,0,runningspeed*Time.deltaTime);

		//transform.position += transform.forward*runningspeed*Time.deltaTime;

	}

	

}



function CanAttackTarget()

{

	//check if in range

	if(Vector3.Distance(transform.position, lookAtTarget.position) > range || Vector3.Distance(transform.position, lookAtTarget.position) < 2 )

	{	

	

		return false;

	}

		

	var hit : RaycastHit;

 	 if(Physics.Linecast(transform.position, lookAtTarget.position, hit))

	{

	

		if(hit.collider.gameObject.tag == "Player")

		{

			//Debug.Log("iseeu");

			return true;

		}

		else

		{

	        //Debug.Log("I see ");

			return false;

		

		}

		//Debug.DrawRay(transform.position, transform.position-lookAtTarget.position t, Color.blue);

	}

	

	return true;

	

}



function OnCollisionEnter (hit : Collision)

{



	if(hit.gameObject.tag == "Player")

	{

		Debug.Log("HITHIT");

	}

Your player is fine. You should try adding a character controller to your enemy. Then you need to get the CC from your enemy to be able to move him around.

var target : Transform;  //the p`layer
var enemy : Transform;   //the enemy
var speed : float = 10;  // well...the speed
        
function Update(){
      enemy.LookAt(target);  // the NPC looks at the player
      // Here you access the Character Controller component and move your NPC with SimpleMove() giving the speed and the direction(forward).
      //As the NPC is looking at you, forward is in your direction.
      enemy.GetComponent(CharacterController).SimpleMove(speed*follower.forward);
      animation.Play("Walk"); //You play the animation if you have one
              }
            }

Now they should naturaly collide just like your character

I found the solution thanks to everyones advice/help. Here is the fixed script incase anyone was having the same problem. Instead of puting a box collider on my enemy, i just added a character controller and attached this script:

var lookAtTarget : Transform;
var runningspeed : int;
var range : int;
var damp : float;
var disable = true;


function Awake()
{
	if (!lookAtTarget)
	{
		lookAtTarget = GameObject.FindWithTag("Player").transform;
		ENEMY_HEALTH = 10;
	}
}

function Update() 
{	
if(lookAtTarget && CanAttackTarget())

	{		
        GetComponent(CharacterController).SimpleMove(runningspeed*transform.forward);	
	}	
}

function CanAttackTarget(){

	if(Vector3.Distance(transform.position, lookAtTarget.position) > range || Vector3.Distance(transform.position, lookAtTarget.position) < 2 )
	{	
		return false;
	}	

	var hit : RaycastHit;

 	 if(Physics.Linecast(transform.position, lookAtTarget.position, hit))
	{
		if(hit.collider.gameObject.tag == "Player")

		{
			GetComponent(SmoothLookAt).enabled = true;
			return true;
		}
		else
		{
	                GetComponent(SmoothLookAt).enabled = false;
		        return false;
		}
	}
	return true;
}

function OnCollisionEnter (hit : Collision){
	if(hit.gameObject.tag == "Player")
	{
		Debug.Log("HITHIT");
	}
}
