touch unity code example
Example: touch gameobject in unity
using UnityEngine; using System.Collections; public class RaycastTest : MonoBehaviour { Vector3 touchPosWorld; //Change me to change the touch phase used. TouchPhase touchPhase = TouchPhase.Ended; void Update() { //We check if we have more than one touch happening. //We also check if the first touches phase is Ended (that the finger was lifted) if (Input.touchCount > 0 && Input.GetTouch(0).phase == touchPhase) { //We transform the touch position into word space from screen space and store it. touchPosWorld = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position); Vector2 touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y); //We now raycast with this information. If we have hit something we can process it. RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward); if (hitInformation.collider != null) { //We should have hit something with a 2D Physics collider! GameObject touchedObject = hitInformation.transform.gameObject; //touchedObject should be the object someone touched. Debug.Log("Touched " + touchedObject.transform.name); } } } }
