I wrote this script from a tutorial, which helps with touch.Inputs. The problem is, the raycasts are 3d, but my game is 2D. I tried different ways to convert the raycasts in the script to 2d, but nothing have worked.
Can someone tell me how to need to be converted?
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class TouchInput : MonoBehaviour {
public LayerMask touchInputMask;
private List<GameObject> touchList = new List<GameObject>();
private GameObject[] touchesOld;
private RaycastHit hit;
// Update is called once per frame
void Update () {
#if UNITY_EDITOR
if(Input.GetMouseButton(0) || Input.GetMouseButtonDown(0) || Input.GetMouseButtonUp(0)) {
touchesOld = new GameObject[touchList.Count];
touchList.CopyTo(touchesOld);
touchList.Clear();
Ray ray = GetComponent<Camera>().ScreenPointToRay(Input.mousePosition);
if(Physics.Raycast(ray,out hit,touchInputMask)) {
GameObject recipient = hit.transform.gameObject;
touchList.Add(recipient);
if(Input.GetMouseButtonDown(0)) {
recipient.SendMessage("OnTouchDown", hit.point, SendMessageOptions.DontRequireReceiver);
} if(Input.GetMouseButtonDown(0)) {
recipient.SendMessage("OnTouchUp", hit.point, SendMessageOptions.DontRequireReceiver);
} if(Input.GetMouseButtonUp(0)) {
recipient.SendMessage("OnTouchStay", hit.point, SendMessageOptions.DontRequireReceiver);
}
}
foreach (GameObject g in touchesOld) {
if(!touchList.Contains(g)) {
g.SendMessage("OnTouchExit", hit.point, SendMessageOptions.DontRequireReceiver);
}
}
}
#endif
}
}
