小游戏＜别让箱子掉下来＞

一些无关紧要的话:

最近心血来潮,想研究下LayaBox,因为我感觉H5是将来的趋势.而Unity对网页的支持始终不那么理想.

于是我变身小白从头开始,网上各种查资料,下载安装包,搭建环境,很顺利的就让LayaBox的案例小游戏运行起来了.

是的,就是我下面要讲的这个游戏<别让箱子掉下来>;研究了几天LayaBox,发现它很多地方其实和Unity有类似的地方,然后我突然发现

这个小游戏有点意思,决定用Unity实现一次,于是就有了这篇文章

上面的都是废话,入正题,先看游戏效果=====>

大致分析下这个游戏==>主要功能可以分为3个模块

1.箱子下落; 2.发射子弹; 3.碰撞检测; 至于其他比如击中显示粒子,不必在意,我也是胡乱做的,没有美感

好,先上代码

//箱子代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class Box : MonoBehaviour
{private GamePlay gp;//粒子private ParticleSystem ps;// Start is called before the first frame updatevoid Start(){gp = GameObject.Find("Canvas").GetComponent();ps = transform.GetChild(0).GetComponent();ps.gameObject.SetActive(false);}private void OnCollisionEnter2D(Collision2D collision){//检测到是底部if (collision.gameObject.name == "DownCheck"){OnDownCheck();}//检测到是子弹else if (collision.gameObject.name == "bullet"){Destroy(collision.gameObject);OnHitBullet();}}void OnDownCheck(){Destroy(gameObject);gp.UpdateMiss();}void OnHitBullet(){Rigidbody2D r2d = transform.GetComponent();int r = Random.Range(0, 5);//给box一个向上的力if (r <2)//五分之二的几率箱子向上弹{r2d.AddForce(Vector2.up * 500);}else//击碎箱子{r2d.gravityScale = 0;ps.transform.SetParent(transform.parent);ps.gameObject.SetActive(true);ps.Play();transform.GetComponent().color = new Color(1, 1, 1, 0);gp.UpdateScore();Destroy(gameObject, 1.25f);}}
}


子弹代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Bullet : MonoBehaviour
{// Start is called before the first frame updatevoid Start(){//添加一个2d刚体Rigidbody2D rig = gameObject.AddComponent();//去掉重力rig.gravityScale = 0;//添加一个向上的力*系数rig.AddForce(Vector2.up * 500);}private void Update(){//子弹超出屏幕自动销毁if (transform.localPosition.y > Screen.height + 200){Destroy(this.gameObject);}}}


主逻辑

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class GamePlay : MonoBehaviour
{//文本显示public Text Txt_score, Txt_miss, Txt_begin;//预制体public Box box;public Bullet bullet;//节点由于存放生成的子弹和箱子public Transform bulletRoot, boxRoot;//箱子下落时差标志float _boxCreateFps = 0;//得分,错过记录int _scroe, _miss;// Start is called before the first frame updatevoid Start(){}// Update is called once per framevoid Update(){//鼠标左键发射if (Input.GetMouseButtonDown(0)){Txt_begin.text = "";Vector3 pos = Input.mousePosition;pos = Camera.main.ScreenToWorldPoint(pos);CreateBullet(pos);}//每隔1.25秒生成一个箱子_boxCreateFps += Time.deltaTime;if (_boxCreateFps >= 1.25f){_boxCreateFps = 0;//随机箱子的x坐标float rand_x = Random.Range((Screen.width / -2) + 250, (Screen.width / 2) - 250);Vector3 pos = new Vector3(rand_x, Screen.height + 110, 0);CreateBox(pos);}}//创建子弹void CreateBullet(Vector3 pos){GameObject go = Instantiate(bullet.gameObject) as GameObject;go.transform.SetParent(bulletRoot);go.transform.position = pos;go.transform.localPosition = new Vector3(go.transform.localPosition.x, go.transform.localPosition.y, 0);go.transform.localScale = Vector3.one;go.name = "bullet";}//创建箱子void CreateBox(Vector3 pos){GameObject go = Instantiate(box.gameObject) as GameObject;go.transform.SetParent(boxRoot);go.transform.localPosition = pos;go.transform.localPosition = new Vector3(go.transform.localPosition.x, go.transform.localPosition.y, 0);float r = Random.Range(1, 2.5f);go.transform.localScale = new Vector3(r, r, 1);}//更新得分public void UpdateScore(){_scroe += 1;Txt_score.text = "击中:" + _scroe;}//更新错过public void UpdateMiss(){_miss += 1;Txt_miss.text = "错过:" + _miss;}}

需要注意:

box之间不需要碰撞,需要在设置里边剔除,不懂的可以自行百度
