[Unity3D]做个小Demo学习Input.touches

学不如做，下面用一个简单的Demo展示的Input.touches各项字段，有图有真相。

本项目已发布到Github，地址在（https://github.com/bitzhuwei/AndroidTouchDemo）。

制作Demo

很简单，只需拉一个Text，然后添加一个脚本。

脚本如下。

using UnityEngine;
using System.Collections;

public class DisplayTouchInfo : MonoBehaviour {

    private UnityEngine.UI.Text lblInfo;

    // Use this for initialization
    void Start () {
        this.lblInfo = this.GetComponent<UnityEngine.UI.Text>();
    }
    
    // Update is called once per frame
    void Update () {
        var builder = new System.Text.StringBuilder();
        builder.AppendLine("touch info:");
        builder.AppendLine(string.Format("deltaTime:{0}", Time.deltaTime));
        builder.AppendLine(string.Format("touchCount:{0}", Input.touchCount));
        builder.AppendLine("i, fingerId, position, rawPosition, deltaPosition, deltaTime, phase, tapCount");
        for (int i = 0; i < Input.touches.Length; i++)
        {
            var touch = Input.touches[i];
            builder.AppendFormat("[{0}]:{1},{2},{3},{4},{5},{6},{7}", i, touch.fingerId, touch.position, touch.rawPosition, touch.deltaPosition, touch.deltaTime, touch.phase, touch.tapCount);
            builder.AppendLine();
        }
        this.lblInfo.text = builder.ToString();
    }
}

使用

注意，必须发布到Android手机上才有效，PC貌似不搭理Input.touchs。
