最近写了一个跑酷游戏,总结下里面的知识点:O(∩_∩)O~
using UnityEngine; using System.Collections; public class Demo : MonoBehaviour { public Vector3 lastMonseDown; /// <summary> /// 判断手指触摸的方向 /// </summary> /// <returns></returns> TouchDir GetTouchDir() { //记录第一次手指点击的坐标点 if (Input.GetMouseButtonDown(0)) { lastMonseDown = Input.mousePosition; } //UICamera.hoveredObject防止NGUI点击穿透问题 if (Input.GetMouseButtonUp(0) && UICamera.hoveredObject == null) { //结束坐标-开始坐标 Vector3 mouseUp = Input.mousePosition; Vector3 touchOffset = mouseUp - lastMonseDown; //滑动超过50像素,算一次正确的滑动 if (Mathf.Abs(touchOffset.x) > 50 || Mathf.Abs(touchOffset.y) > 50) { if (Mathf.Abs(touchOffset.x) > Mathf.Abs(touchOffset.y) && touchOffset.x > 0) { return TouchDir.Right; } else if (Mathf.Abs(touchOffset.x) > Mathf.Abs(touchOffset.y) && touchOffset.x < 0) { return TouchDir.Left; } else if (Mathf.Abs(touchOffset.x) < Mathf.Abs(touchOffset.y) && touchOffset.y > 0) { return TouchDir.Top; } else if (Mathf.Abs(touchOffset.x) < Mathf.Abs(touchOffset.y) && touchOffset.y < 0) { return TouchDir.Bottom; } } else { return TouchDir.None; } } return TouchDir.None; } } /// <summary> /// 触摸的方向 /// </summary> public enum TouchDir { None, Left, Right, Top, Bottom }
