在unity3D，点击触摸=？ [英] In unity3D, Click = Touch?

问题描述

我想在我的游戏对象的2D检测点击/触摸事件。

I want to detect click/touch event on my gameObject 2D.

这是我的代码：

void Update()
{
   if (Input.touchCount > 0)
   {
     Debug.Log("Touch");
   }
}

的debug.log（触摸）; 不会当我点击屏幕或我的游戏对象显示

Debug.Log("Touch"); does not show when I click on screen or my gameObject.

推荐答案

简答题：是的，触摸可与 Input.GetMouseButtonDown（）

Short answer: yes, touch may be handled with Input.GetMouseButtonDown().

• <处理p> Input.GetMouseButtonDown（）， Input.mousePosition 和相关职能的工作在触摸屏上自来水（这是种奇怪，但欢迎）。如果没有多点触控游戏，这是保持在编辑器中游戏运作良好，同时仍保持触摸输入的设备的好方法结果

  虽然这是很好的测试，我相信 Input.GetTouch （）应在生产代码中使用。

• Input.GetMouseButtonDown(), Input.mousePosition, and associated functions work as tap on the touch screen (which is kind of odd, but welcome). If you don't have a multi-touch game, this is a good way to keep the in-editor game functioning well while still keeping touch input for devices.

  Though it is good for testing, I believe Input.GetTouch() should be used in production code.

有趣的方法是增加触控操作，以 OnMouseUp（ ） / onmousedown事件（）事件：

Interesting approach is to add touch handling to OnMouseUp()/OnMouseDown() event:

//  OnTouchDown.cs
//  Allows "OnMouseDown()" events to work on the iPhone.
//  Attach to the main camera.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class OnTouchDown : MonoBehaviour {
    void Update () {
        // Code for OnMouseDown in the iPhone. Unquote to test.
        RaycastHit hit = new RaycastHit();
        for (int i = 0; i < Input.touchCount; ++i)
            if (Input.GetTouch(i).phase.Equals(TouchPhase.Began)) {
                // Construct a ray from the current touch coordinates
                Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
                if (Physics.Raycast(ray, out hit))
                    hit.transform.gameObject.SendMessage("OnMouseDown");
            }
    }
}
