Question by OfficialLupaz · Feb 20, 2017 at 07:44 AM · transformvector3aifloatcompiler

Argument `#1' cannot convert `float' expression to type `UnityEngine.Vector3 ?

i'm trying to make an Advanced AI script but i'm getting the following errors: Assets/Scripts/AI/AvancedAI.cs(38,24): error CS1503: Argument #1' cannot convert float' expression to type UnityEngine.Vector3' Assets/Scripts/AI/AvancedAI.cs(38,24): error CS1503: Argument #1' cannot convert float' expression to type UnityEngine.Vector3' using UnityEngine;

 public class AvancedAI : MonoBehaviour {
 
     public int health = 100;
     public float viewRange = 25f;
     public float attackRange = 5f;
 
     public bool isChasing = false;
 
     private UnityEngine.AI.NavMeshAgent agent;
     private Transform playerTransform;
 
     private void Start()
     {
         agent = GetComponent<UnityEngine.AI.NavMeshAgent> ();
     }
 
     private void Update()
     {
         Ray ray = new Ray (transform.position, Vector3.forward);
         RaycastHit hitInfo;
 
         if (Physics.Raycast (ray, out hitInfo, viewRange)) 
         {
             if (hitInfo.collider.tag == "Player") 
             {
                 if (isChasing == false) 
                 {
                     playerTransform = hitInfo.collider.GetComponent<Transform> ();
                     isChasing = true;
                 }
             }
         }
 
         if (Physics.Raycast (viewRange, out hitInfo, attackRange))
 
         Debug.DrawRay (ray.origin, ray.direction * viewRange, Color.red);
 
         if (isChasing == true) 
         {
             agent.SetDestination (playerTransform.position);
         }
     }
 }
 

What did i do wrong?

I think the problem is with the second raycast first argument viewRange. You should change it to ray.
