Can't get touch position in variable?
I am new in unity trying to get touch position but having error this line:
Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
here is my code:
using UnityEngine;
using System.Collections;
public class enemy : MonoBehaviour {
// Update is called once per frame
void Update () {
Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
Vector2 touchPos = new Vector2(wp.x, wp.y);
transform.position = touchPos;
}
}
Error: Index out of bounds.
if your problem solved by the answer just accept so that it can be useful for others too..

Firstly check if there are any touches before you access the Touches array.
So the code becomes:
public class enemy : MonoBehaviour {
// Update is called once per frame
void Update () {
if(Input.touchCount > 0) {
Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
Vector2 touchPos = new Vector2(wp.x, wp.y);
transform.position = touchPos;
}
}
}
Set position like this:
transform.position = new Vector3(touchPos.x, touchPos.y);
Touch events wont work in editor. You have to test them on device itself.
yeah i didnt know that... Thanks a lot... i already have done this... tested on device
