public static Touch GetTouch (int index);

描述

返回表示特定触摸状态的对象。(不分配临时变量)。

GetTouch 返回一个 Touch 结构。 例如,Touch 可以随压力返回。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public float speed = 0.1F; void Update() { if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) { // Get movement of the finger since last frame Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;

// Move object across XY plane transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0); } } }

另一个示例:

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject projectile; public GameObject clone; void Update() { for (int i = 0; i < Input.touchCount; ++i) { if (Input.GetTouch(i).phase == TouchPhase.Began) clone = Instantiate(projectile, transform.position, transform.rotation) as GameObject; } } }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public GameObject particle; void Update() { for (int i = 0; i < Input.touchCount; ++i) { if (Input.GetTouch(i).phase == TouchPhase.Began) { // Construct a ray from the current touch coordinates Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position); // Create a particle if hit if (Physics.Raycast(ray)) Instantiate(particle, transform.position, transform.rotation); } } } }
