[SOLVED] Physics.RaycastNonAlloc allocating memory ?!

Question

Hi,

I just found out that I can use Physics.RaycastNonAlloc to prevent memory allocation. I am using a script to manage the input in my game and everything works fine except for allocating memory each time a mouse or touch input is made. The thing is that I can't find a single script even in Unity's documentation on how to use Physics.RaycastNonAlloc, so if someone could help me I'd be grateful. I just need to convert this script using Physic.RaycastNonAlloc and not Physics.Raycast to execute a function in my game.

Here is the script I am using now :

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class TouchInput : MonoBehaviour {
 
     // Singleton     
     private  static TouchInput instance;      
 
     // Construct     
     private TouchInput() {}      
 
     //  Instance     
     public static TouchInput Instance {         
         get {             
             if (instance == null)
                 instance = GameObject.FindObjectOfType (typeof(TouchInput)) as TouchInput;             
             return instance;         
         }  
     }
 
     public LayerMask touchInputMask;
     private RaycastHit hit;
 
     Ray ray;
     GameObject recipient;
 
     public delegate void OnClickEvent(GameObject g);
     public event OnClickEvent OnTouchDown;
 
 
     void Update () 
     {
 
         #if UNITY_EDITOR
         if (GameControl.control.GetComponent<GamePlay>().isPlaying) 
         {
             if (Input.GetMouseButton(0) || Input.GetMouseButtonDown(0) || Input.GetMouseButtonUp(0) )
             {
                 ray = GetComponent<Camera> ().ScreenPointToRay (Input.mousePosition);
 
                 if (Physics.Raycast (ray, out hit, touchInputMask))
                 {
                     recipient = hit.transform.gameObject;
                 }
                 if (Input.GetMouseButtonDown(0))
                 {
                     OnTouchDown(recipient);
                 }
             }
         }
 
         #endif
 
         if (GameControl.control.GetComponent<GamePlay>().isPlaying) 
         {
             if (Input.touchCount > 0)
             {
                 foreach (Touch touch in Input.touches)
                 {
                     ray = GetComponent<Camera> ().ScreenPointToRay (touch.position);
 
                     if (Physics.Raycast (ray, out hit, touchInputMask))
                     {
                         recipient = hit.transform.gameObject;
                     }
                     if (touch.phase == TouchPhase.Began) 
                     {
                         OnTouchDown (recipient);
                     }
                 }
             }
         }
     }
 }

You can also see the image below to see how much memory is this script allocating each time I click over the object which has the same layer as "touchInputMask". alt text

If you need more information I can share it with you.

Thank you, Gerald.

I found out by myself (maybe I'm not using it right) how to use Physics.RaycastNonAlloc. The strange thing is that Physics.RaycastNonAlloc is allocating memory even more than Physics.Raycast. I am pasting the codes I am using again so you can have a look:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 public class TouchInput : MonoBehaviour {
 
     // Singleton     
     private  static TouchInput instance;      
 
     // Construct     
     private TouchInput() {}      
 
     //  Instance     
     public static TouchInput Instance {         
         get {             
             if (instance == null)
                 instance = GameObject.FindObjectOfType (typeof(TouchInput)) as TouchInput;             
             return instance;         
         }  
     }
 
     public LayerMask touchInputMask;
     private RaycastHit hit;
 
     private RaycastHit[] results;
 
     string tagName = "TouchInput";
 
     Ray ray;
     GameObject recipient;
 
     public delegate void OnClickEvent(GameObject g);
     public event OnClickEvent OnTouchDown;
 
     void Start()
     {
         results = new RaycastHit[255];
     }
 
     void Update () 
     {
 
         #if UNITY_EDITOR
         if (GameControl.control.GetComponent<GamePlay>().isPlaying) 
         {
             if (Input.GetMouseButton(0) || Input.GetMouseButtonDown(0) || Input.GetMouseButtonUp(0) )
             {
                 ray = GetComponent<Camera> ().ScreenPointToRay (Input.mousePosition);
 
                 if(Physics.RaycastNonAlloc(ray, results, touchInputMask) > 0)
                 {
                     /*foreach(RaycastHit hit in results)
                     {
                         if(hit.collider != null)
                         {
                         //recipient = hit.transform.gameObject;
                         }
                     }*/
                 }
                     
                 /*if (Physics.Raycast (ray, out hit, touchInputMask))
                 {
                     recipient = hit.transform.gameObject;
                 }*/
                 if (Input.GetMouseButtonDown(0))
                 {
                     OnTouchDown(recipient);
                 }
             }
         }
 
         #endif
 
         /*if (GameControl.control.GetComponent<GamePlay>().isPlaying) 
         {
             if (Input.touchCount > 0)
             {
                 ray = GetComponent<Camera> ().ScreenPointToRay (Input.GetTouch(0).position);
 
                 if (Physics.Raycast (ray, out hit, touchInputMask))
                 {
                     recipient = hit.transform.gameObject;
                 }
                 if (Input.GetTouch(0).phase == TouchPhase.Began) 
                 {
                     OnTouchDown (recipient);
                 }
             }
         }*/
     }
 }

I hope someone from Unity can have an answer for this cause nodody seems to care about this forum and the questions that are being asked here. :P Thank's.

I've you try this int nbHits = Physics.RaycastNonAlloc(ray, results, touchInputMask) ; for(int i=0;i
