Third Person Melee Combat Lock-on

Unity Engine

Hello, just been writing a script in Javascript for a lock on system.

Trying to get the system to be similar to Zelda. So when I press a button the player looks at the nearest enemy and always faces them while the “lock-on” button is held down.

Right now the closest enemy is being determined but the problem is when I hold down “T” the player just jitters rather than looking straight at the enemy…

#pragma strict
/*=================
  Lock-on to Enemy
=================*/

var targeting : boolean = false; 

var enemyLocations : GameObject[];
var closest : GameObject;

function Update() {
    
    if(Input.GetKeyDown(KeyCode.T)) // If " T " is held down.
    {       
    	Debug.Log("FindingClosestEnemy"); 
    	FindClosestEnemy(); // Run this function
    	Debug.Log(closest);
    	
    	if (targeting == false) 
    		{
   	 		targeting = true; // Targetting becomes true
   	 		}
    }
    
    if(Input.GetKeyUp(KeyCode.T))
    {
    	targeting = false; // When " T " comes back up, targetting becomes false.
    }
    	
    if(targeting == true)
    {
    	LockOn(); // Lock-on when targetting becomes true;
    } 
}

function FindClosestEnemy() : GameObject {
enemyLocations = GameObject.FindGameObjectsWithTag("Enemy"); 	// Find all game objects with tag Enemy
var distance = Mathf.Infinity; 
var position = transform.position; 

    for (var go : GameObject in enemyLocations) // Go through all enemy tags and find the nearest one.
        { 
            var diff = (go.transform.position - position);
            var curDistance = diff.sqrMagnitude; 
 
    		if (curDistance < distance) 
            	{
                closest = go; 
                distance = curDistance;
                }      
        }
        
    
}

function LockOn() {
    transform.LookAt(closest.transform); // Look at the closest enemy.
    Debug.Log("looking at closest"); 
}

Got a Rigidbody on your player? Turning on the interpolation could solve your problem.

If not, I’d probably just write that part myself. Get the vector pointing at the target (Or just let an empty gameobject look at it), and then use lerp or slerp to slowly interpolate between current rotation and target rotation.
