unity3d 射弹基础案例代码分析

Posted 2020-08-22

 1 #pragma strict
 2 import UnityEngine.UI;
 3 
 4 function Start () {
 5     
 6 }
 7 var speed : int = 5;
 8 var newobject : Transform;
 9 var sdshu : int = 0;
10 var xmshu : int = 0;
11 
12 
13 function Update () {
14     //yidong
15     var x : float = Input.GetAxis("Horizontal")*Time.deltaTime*speed;
16     var z : float = Input.GetAxis("Vertical")*Time.deltaTime*speed;
17     if (Input.GetKey(KeyCode.H)){
18         transform.Translate(0,5*Time.deltaTime,0);
19     }
20     if (Input.GetKey(KeyCode.N)){
21         transform.Translate(0,-5*Time.deltaTime,0);
22     }
23     transform.Translate(x,0,z);
24     //print (x);
25     //kaihuo
26     if (Input.GetButtonDown("Fire1")){
27         var n : Transform = Instantiate(newobject,transform.position,transform.rotation);
28         var fwd : Vector3 = transform.TransformDirection(Vector3.forward);
29         n.GetComponent(Rigidbody).AddForce(fwd*3000);
30         sdshu++;
31         gameObject.Find("Canvas/wenzi").GetComponent(Text).text="射弹数：" +sdshu+  "  消灭数：" + xmshu;
32 
33     }
34     //xuanzhuan
35     if (Input.GetKey(KeyCode.Q)){
36         transform.Rotate(0,-25*Time.deltaTime,0,Space.Self);
37     }
38     if(Input.GetKey(KeyCode.E)){
39         transform.Rotate(0,25*Time.deltaTime,0,Space.Self);
40     }
41     if (Input.GetKey(KeyCode.Z)){
42         transform.Rotate(-25*Time.deltaTime,0,0,Space.Self);
43     }
44     if (Input.GetKey(KeyCode.C)){
45         transform.Rotate(25*Time.deltaTime,0,0,Space.Self);
46     }
47     
48 }

这是射击脚本。

 1 function Start () {
 2     
 3 }
 4 var sd : int;
 5 var xm : int;
 6 function Update () {
 7     if(gameObject.transform.position.y<0){
 8         xm = gameObject.Find("Camera").GetComponent(sheji).xmshu++;
 9         sd = gameObject.Find("Camera").GetComponent(sheji).sdshu;
10         gameObject.Find("Canvas/wenzi").GetComponent(Text).text="射弹数：" +sd+  "  消灭数：" + xm;
11         if (xm > 20){
12             gameObject.Find("Canvas/wenzi").GetComponent(Text).text="恭喜过关！";
13             gameObject.Find("Camera").GetComponent(sheji).enabled=false;
14             gameObject.Find("dimian").GetComponent(restar).enabled=true;
15         }
16         Destroy(gameObject);
17     }
18     
19 }

这是检查脚本。

 1 #pragma strict
 2 @script RequireComponent(Audiosource)
 3 import UnityEngine.SceneManagement ;
 4 
 5 function OnGUI(){
 6     var audio: AudioSource = GetComponent.<AudioSource>();
 7     if(GUI.Button(Rect(180,100,60,30),"退 出")){
 8         Application.Quit();
 9     }
10     if(GUI.Button(Rect(280,100,60,30),"重新开始")){
11         SceneManager.LoadScene(SceneManager.GetActiveScene().name);
12     }
13     if(GUI.Button(Rect(10,160,100,50),"paly"))
14         audio.Play();
15     if(GUI.Button(Rect(10,220,100,50),"Pause"))
16         audio.Pause();
17     if(GUI.Button(Rect(10,280,100,50),"Stop"))
18         audio.Stop();
19 }

这是重启脚本，

var audio: AudioSource = GetComponent.<AudioSource>();可以不设置变量audio，   GetComponent.<AudioSource>().Pause();这样使用。

1 #pragma strict
2 import UnityEngine.UI;
3 
4 function OnCollisionEnter(){
5     gameObject.Find("Canvas/wenzi").GetComponent(Text).text = "大玉螺旋丸！";
6     gameObject.Find("Point light").GetComponent(Light).enabled = false;
7     gameObject.Find("Spotlight").GetComponent(Light).enabled = false;
8     Destroy(gameObject);
9 }

这是碰撞检测脚本。

1 #pragma strict
2 
3 function  OnGUI(){
4     if(GUI.Button(Rect(180,400,60,30),"开始游戏")){
5         Application.Quit();
6     }
7 }

这里说明下按钮的使用代码。SceneManager.LoadScene(SceneManager.GetActiveScene().name);可以在loadScene实参直接使用“场景名字“。
