unity基础开发----常用代码鼠标滑动，触摸事件

判断鼠标向左还是向右滑动

private var first = Vector2.zero;
private var second = Vector2.zero;
function Update () {
}
function OnGUI () {
if(Event.current.type == EventType.MouseDown){//记录鼠标按下的位置
first = Event.current.mousePosition ;
}
if(Event.current.type == EventType.MouseDrag){//记录鼠标拖动的位置
second = Event.current.mousePosition ;
if(second.xfirst.x){//拖动的位置的x坐标比按下的位置的x坐标大时,响应向右事件
print("right");
}
first = second;
}
}

屏幕触摸事件， 移动物体代码

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public float speed = 0.1F;
    void Update() {
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
            Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
            transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);
        }
    }
}
