Unity-飞⾏射击实例的代码
花了⼀天的时间，照着官⽅的说明将spaceshoot这个DEMO撸了⼀遍，实现了⼀个简单飞⾏射击游戏应有的⼩功能，本想着⽤这个组件把这个游戏做成⼀个联⽹的，⽆奈只能实现飞机运动之间的同步，其余部分画⾯都是不同步的。等经过进⼀步的学习之后我会再把这个DEMO 进⾏完善。
接下来就分析⼀下这个DEMO的各个游戏对象与组件的关系。
1.场景：这个飞⾏射击游戏只有需要⼀个场景，⼀张⽤图⽚来做背景的星空图，⼀些粒⼦效果来模拟星星。
2.游戏对象：1.1玩家飞机：⽤WASD来进⾏控制，移动有范围限制，⿏标左键开⽕，撞到⼦弹，陨⽯，敌机会爆炸并附带⾳效；
1.2 陨⽯：在玩家上⽅随机⽣成并向下移动并具有旋转，离开边界范围会⾃动销毁，被⼦弹击中会爆炸，撞击到玩家飞机会爆炸并附带⾳效 1.3 敌机：在玩家上⽅随机⽣成并向下移动，并且可以开⽕，被⼦弹击中会爆炸，与玩家飞机相撞会爆炸，超出边界范围会销毁
1.4 ⼦弹：可以由玩家和敌机⽣成，在Z轴上具有⼀定的速度，遇见玩家，陨⽯，敌机，进⾏爆炸并附带⾳效，超过⽣命周期会销毁
3.UI界⾯：需要⼀个计分板，玩家死亡后的结束游戏提⽰，和按R重新开始提⽰
脚本：
3.1玩家控制脚本
3.2敌对物体移动与旋转位置随机化脚本using UnityEngine;using System.Collections;using UnityEngine.Networking;[System.Serializable]public class Boundary { public float xMin,zMin,xMax,zMax;//这是设定玩家运动的边界范围}public class playercontroller : MonoBehaviour { public float speed;//移动速度 public Boundary boundary;//边界 public float tilt = 4;//旋转速度 public float fireRate = 0.2f;//开或延迟 public GameObject shot;//⼦弹对象 public Transform shotspawn;//⼦弹⽣成地点 private float nextfire = 0;//开⽕间隔 // U this for initialization void Update () { //if (isLocalPlayer) { if (Input.GetButton ("Fire1") && Time.time > nextfire) {//按下⿏标左键并且时间⼤于开⽕间隔 nextfire = Time.time + fireRate;//更新最近开⽕时间 Instantiate (shot, shotspawn.position, ation); //⽣成⼦弹对象 GetComponent<AudioSource> ().Play ();//播放射击⾳效 } //} } // Update is called once per frame void FixedUpdate () { //if (isLocalPlayer) { float moveHorizontal = Input.GetAxis ("Horizontal");//获得⽔平输⼊值 float moveVertical = Input.G
etAxis ("Vertical");//获得竖直⽅向上的输⼊值 Vector3 movement = new Vector3 (moveHorizontal, 0, moveVertical);//定义⼀个三维变量⽤于储存玩家进⾏的移动操作 Rigidbody rb = GetComponent<Rigidbody> (); if (rb != null ) { rb.velocity = movement * speed;//设定刚体在某⽅向上的速度 rb.position = new Vector3 (Mathf.Clamp (rb.position.x, boundary.xMin, boundary.xMax), 0, Mathf.Clamp (rb.position.z, boundary.zMin, boundary. rb.rotation = Quaternion.Euler (0, 0, rb.velocity.x * -tilt);//计算旋转，因为Z 轴上的旋转逆时针为正值，所以假设向左移动，X 轴上的速度为负值，这时 } } //}}
