Turrets; Error CS0161 C#

[greg1992]

Hiya all, making my own turret system as we speak however i’m getting a rather annoying error, i know part of my code is contradicting something.

“Assets/Standard Assets/New Folder/TurretScript.cs(62,21): error CS0161: `TurretScript.FindClosestEnemy()': not all code paths return a value”

using UnityEngine;

using System.Collections;

 

public class TurretScript : MonoBehaviour {

    

    

	
public Transform Bullet;
	
public Transform Enemy;
	

public int cost;

public float Radius;
    
	
		
		
		
   
    
	



 
    

 

    // Use this for initialization

    void Start () {
		
    

    }

    

    // Update is called once per frame

    void Update () {
	
}
	
	void OnTriggerEnter(Collider collider)
	{
		if(collider.gameObject.tag=="Enemy")
		{
			Debug.Log ("EnemyIsWorking");
		FindClosestEnemy();
		}
	}
	
	 GameObject FindClosestEnemy() {
        GameObject[] gos;
        gos = GameObject.FindGameObjectsWithTag("Enemy");
        GameObject closest = null;
        float distance = Mathf.Infinity;
        Vector3 position = transform.position;
        foreach (GameObject go in gos) {
            Vector3 diff = go.transform.position - position;
            float curDistance = diff.sqrMagnitude;
            if (curDistance < distance) {
                closest = go;
                distance = curDistance;
            }
        }
       LookAtTarget();
    }
	
    
	void LookAtTarget()
	{
	Transform.rotation = Quaternion.identity;
		
	}
	
	
	
}

Add:

return closest;

After calling: ‘LookAtTarget();’ inside FindClosestEnemy();

You have wrote a function that returns a value - it must do so.

Note:

Looking at your code it looks as if you don’t need that return value since you do not set it.

If that is the case, simply change ‘GameObject’ to ‘void’ in the return type definition at the function name line.

void FindClosestEnemy()

instead of

GameObject FindClosestEnemy()

This way, you don’t need to return the value (and ditch my first suggestion).
