A lot of errors in C# touch support script.

Unity Engine
1

I made a touch handler and there are quite a few errors. Im new to Unity and i have no idea what i did wrong so please explain. Also i never used c# before. I normally use c++ or c.

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) ){
        Ray ray = GetComponent<Camera>().ScreenPointToRay (Input.mousePosition);

        if(Physics.Raycast(ray,out hit,TouchInputMask)) {
        GameObject recipient = hit.transform.gameObject;

        if(Input.GetMouseButtonDown(0)){
        recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver);

        }
        if(Input.GetMouseButtonUp(0)){
        recipient.SendMessage("OnTouchEnded",hit.point,SendMessageOptions.DontRequireReceiver);

        }
        if(Input.GetMouseButton(0)){
        recipient.SendMessage("OnTouchStationary",hit.point,SendMessageOptions.DontRequireReceiver);

        }
        if(Input.GetMouseButtonUp(0)){
        recipient.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);

        }

        }
        }
        #endif

        foreach (Touch touch in Input.touches) {
            Ray ray = GetComponent<Camera>().ScreenPointToRay (touch.position);

            if(Physics.Raycast(ray,out hit,TouchInputMask)){
                GameObject recipient = hit.transform.gameObject;

                if(touch.phase == TouchPhase.Began){
                    recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver);

                }
                if(touch.phase == TouchPhase.Ended){
                    recipient.SendMessage("OnTouchEnded",hit.point,SendMessageOptions.DontRequireReceiver);

                }
                if(touch.phase == TouchPhase.Stationary){
                    recipient.SendMessage("OnTouchStationary",hit.point,SendMessageOptions.DontRequireReceiver);

                }
                if(touch.phase == TouchPhase.Canceled ){
                    recipient.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);

                }

            }
    }
}
}

Errors:

Hi @Moustache-Spy

didn’t read your code completely, but at least the first error you get, is just what it says, that you don’t have LayerMask variable called “TouchInputMask” you have it in lowercase:

public LayerMask touchInputMask;

and

if(Physics.Raycast(ray,out hit,TouchInputMask))

which should be

if(Physics.Raycast(ray,out hit, touchInputMask))  // with lowercase t
