[SOLVED] Physics.RaycastNonAlloc allocating memory ?!

[G3R1]

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”.

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.
Thank’s.

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