Why am I getting this error message?
I'm getting this message in the unity console window: ArgumentException: Index out of bounds. UnityEngine.Input.GetTouch (Int32 index) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/InputBindings.gen.cs:619) TouchTest2.Update () (at Assets/TouchTest2.cs:18)
This is my code in Microsoft visual studio: using System.Collections; using System.Collections.Generic; using UnityEngine;
public class TouchTest2 : MonoBehaviour {
Ray ray;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void Update()
{
if (Input.touchCount > 0 || Input.GetTouch(0).phase == TouchPhase.Began)
{
ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
Debug.DrawRay(ray.origin, ray.direction * 20);
if (Physics.Raycast(ray, Mathf.Infinity))
{
Debug.Log("Hit Something");
}
}
}
}
The if statement should be:
if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) {
//...
}
In this setup, if Input.touchCount is less than or equal to zero ( Input.touchCount > 0 is false) then the second condition is never evaluated.
With the OR operator, this is not the case. It's looking for a 0th touch input when there is none.
