How to get objects with a specific component and store them in an array?

So, i made this code to switch weapons, and all i'm trying to do is get how much weapons the player has, so i know how to set the array, and then, put all weapons into the array, however, how do i get the objects with the "WeaponFire" component? So that i don't need to set the array length before running the game, because i wont always have the same number of weapons.

BTW, this is not an FPS, nor a TPS, it is a car combat game.

Code:

Code (JavaScript):

1. #pragma strict
2.  
3. var currentWeapon = 0;
4. var Weapons : WeaponFire[];
5.  
6. function getSelectedWeapon() : WeaponFire
7.     {
8.     return Weapons[currentWeapon];
9.     }
10.  
11.  
12. function Start()
13.     {
14.    
15.     if (currentWeapon >= Weapons.length) currentWeapon = Weapons.length-1;
16.    
17.     for (var i=0; i<Weapons.length; i++)
18.         DisableWeapon(Weapons[i]);
19.    
20.     SelectWeapon(Weapons[currentWeapon]);
21.     }
22.  
23.  
24. function Update () {
25.    
26.     if (Input.GetKeyDown(KeyCode.PageUp))
27.         SwitchWeapon(-1);
28.        
29.     if (Input.GetKeyDown(KeyCode.PageDown))
30.         SwitchWeapon(1);
31. }
32.  
33. function SwitchWeapon (iDir : int)
34.     {
35.     if (Weapons.length < 2) return;
36.    
37.     // Desactivar coche previo
38.    
39.     DisableWeapon(Weapons[currentWeapon]);
40.        
41.     // Seleccionar coche nuevo
42.    
43.     currentWeapon += Mathf.Sign(iDir);
44.     if (currentWeapon < 0) currentWeapon = Weapons.length-1;
45.     else if (currentWeapon >= Weapons.length) currentWeapon = 0;
46.    
47.     SelectWeapon(Weapons[currentWeapon]);
48.     }
49.    
50.    
51. // Desactivar el coche dado. No depende de variables globales.
52.    
53. function DisableWeapon(Weapon : WeaponFire)
54.     {
55.     Weapon.weaponSelected = false;
56.     }
57.  
58.    
59. // Selecciona el coche dado. Lo activa y obtiene sus componentes.
60.  
61. function SelectWeapon(Weapon : WeaponFire)
62.     {
63.     Weapon.weaponSelected = true;
64.     }
65.  
66.

Uhm, that's not it, i'm trying to create an array of all objects that contain a specific component, and not trying to get a component from one single object.

 

You can use

Code (CSharp):

1. MyComponent[] myComponents = GameObject.FindObjectsOfType<MyComponent>();

It's a slow function though, so best to only use it at load time, not every frame

 

Sorry to ask, but, how do i do that with Javascript? And, no problem being slow for this script, as it is just for switching weapons.

Any way to use that with my corrent script, or i will have to re-write all of it?

 

http://docs.unity3d.com/ScriptReference/Object.FindObjectsOfType.html : Scripting Reference, toggle between languages using the buttons upper-right in the page

 

Thank you all guys, i'll fiddle with this and see what i can get.

 

I ended up creating a very different setup for dynamic weapons, i simply created an empty and i attach all weapons to this empty, the script then counts how many child objects this empty has, and sets the array based on this. If anyone is having trouble with a similar issue, i'll elave the code here:

Code (JavaScript):

1.     #pragma strict
2.    
3.     var currentWeapon = 0;
4.    
5.     function Awake(){
6.         SelectWeapon(0);
7.     }
8.    
9.     function Update(){
10.     var maxWeapons : int = transform.childCount - 1;
11.    
12.     if(Input.GetAxis("Mouse ScrollWheel") > 0){
13.         if(currentWeapon + 1 <= maxWeapons){
14.             currentWeapon++;
15.         }
16.         else{
17.             currentWeapon = 0;
18.         }
19.         SelectWeapon(currentWeapon);
20.     }
21.     else if (Input.GetAxis("Mouse ScrollWheel") < 0){
22.         if(currentWeapon - 1 >= 0){
23.             currentWeapon--;
24.         }
25.         else{
26.             currentWeapon = maxWeapons;
27.         }
28.         SelectWeapon(currentWeapon);
29.     }
30.    
31.     if(currentWeapon == maxWeapons + 1){
32.         currentWeapon = 0;
33.     }
34.     if(currentWeapon == -1){
35.         currentWeapon = maxWeapons;
36.     }
37. }
38.  
39. function SelectWeapon (index : int){
40.     for (var i = 0; i < transform.childCount; i++){
41.  
42.         if (i == index){
43.             transform.GetChild(i).gameObject.GetComponent(WeaponFire).weaponSelected = true;
44.         }
45.         else{
46.             transform.GetChild(i).gameObject.GetComponent(WeaponFire).weaponSelected = false;
47.         }
48.     }
49. }
