How to get the Distance, Collision and Direction for each game object in my list?

Question

So, I've a list with a game objects and I'm very uncertan about how to get the distance, collistion, direction for each of them. It is sutable to use the SphereCast, to cover my needs, becouse I know it is only class functions that can do it for me. I wrote the code to accomplish the task, but its grabbing the data just for 1 game object in my list, insted of all of them, I wish to grab data from all game object in my list. Any ideas to change the code or approaches?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class example : MonoBehaviour {
    
     RaycastHit hit;
     
     Vector3 direction;
         
     public static  List<float> sphereCast = new List<float>();
     
     void Update() {
         CharacterController charCtrl = GetComponent<CharacterController>();
         foreach(GameObject g in xmlreaderUnityObject.unityGameObjectsToCDP)
         {
             Vector3 p1 = g.transform.position;
             if (Physics.SphereCast(p1, charCtrl.height / 2, g.transform.forward, out hit,1))    
             { 
                 float distance = 0;
                 float angleBetween = 0;
                 float contact = 0; 
                 if(hit.collider.enabled)
                 {
                     direction = hit.transform.position - p1;
                     angleBetween = Vector3.Angle(g.transform.forward, direction);
                     contact = 1;
                     distance =  hit.distance;
                 }
                 print("Distance: "+ distance + " Collision: " + contact + " Direction: " + angleBetween + " hit point: "
                         +hit.point + " player position: " + p1);
                     
                 sphereCast.Add(contact);
                 sphereCast.Add(distance);
                 sphereCast.Add(angleBetween);
             }
         }
         
     }
 }

Please use Physics.OverlapSphere() instead, because it returns array of colliders instead of only one argument (RaycastHit) returned by Physics.SphereCast. Please refer to http://docs.unity3d.com/Documentation/ScriptReference/Physics.OverlapSphere.html

the Physics.OverlapSphere just returns an array with all colliders touching or inside the sphere. But, I need to return distance, collistion, direction for each of game objects in my array.

that is why I used the Physics.SphereCast

[code=CSharp] //Just assign these references however you need to. Either at run time, or in the inspector, or whatever suits your needs. //Use an angle_range of 2 - 30 for best results. A value of 2 being directly in front of the entity. Increasing this value //increases the entity's peripheral vision. Using 0 is not recommended. The value will most likely never equal 0.

 Transform entity;
 Vector3 object_position;
 [Range(2, 30)]
 float angle_range = 30f;
 [Range (0.5f, 5f]
 float min_allowed_distance = 3f;
 
 float angle = Vector3.Angle(entity.forward, object_position - entity.position);
 //Debug.Log("Object Angle: " + angle);
 if (Mathf.Abs(angle) < angle_range)
 {
      print("Object in front of the entity: " + angle);
       if (distance < min_allowed_distance)
       {
            //Execute your next commands/methods here.
       }
 }

[/code]
