How to use generics in unity javascript

This is some code based on http://unity3d.com/support/documentation/Manual/MonoUpgradeDetails.html and http://msdn.microsoft.com/en-us/library/y52x03h2.aspx
It showcases the use of generics in unity js.

Code (csharp):

1.  
2. import System.Collections.Generic;
3.  
4. function Start ()
5. {
6.     var list : List.<String>;
7.     list = new List.<String>();
8.     //Capacity is the number of elements that the List<T> can store before resizing is required
9.     //Count is the number of elements that are actually in the List<T>.
10.     Debug.Log("list capacity is " +list.Capacity);
11.     Debug.Log("list count is " +list.Count);
12.     Debug.Log("Adding 4 entries");
13.    
14.     list.Add("Generics");
15.     list.Add(" work");
16.     list.Add(" in");
17.     list.Add(" js");
18.     list.Add(" too.");
19.    
20.     Debug.Log("Note that now capacity is bigger than count");
21.  
22.     Debug.Log("list capacity is " +list.Capacity);
23.     Debug.Log("list count is " +list.Count);
24.    
25.     //js cannot have foreach but can use for in
26.     var sentence:String;
27.  
28.     for( var word:String in list)
29.     {
30.         sentence +=word;
31.     }
32.     Debug.Log(sentence);
33.     Debug.Log("list.Contains(\"generics\") is " + list.Contains("generics"));
34.     Debug.Log("list.Insert(5, \" Unity js rocks !\");" +" inserts a new item at the end of the list");
35.     list.Insert(5, " Unity js rocks !");
36.     Debug.Log("Let's check it");
37.     sentence = "";
38.    
39.     for( var word:String in list)
40.     {
41.        sentence +=word;
42.     }
43.     //For more methods of List check out http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx
44.     //Or google c sharp List
45.    
46.  
47. }

 

Thanks for this it is very helpful

 

Code (csharp):

1.  
2.     list.Add("Generics");
3.     list.Add(" created");
4.     list.Add(" in");
5.     list.Add(" C#");
6.     list.Add(" etc.");
7.     list.Add(" can");
8.     list.Add(" be");
9.     list.Add(" accessed");
10.     list.Add(" by");
11.     list.Add(" js");
12.     list.Add(" (us)");
13.     list.Add(" too.");
14.  

FTFY

 

You didn't "fix" anything though.

Not relevant with the topic specifically, but can anyone tell me why i should use java script rather than c# ?
Does it make a difference on mobile platforms or something?

 

By and large it's personal preference.

 

Really, please don't start that up here, it's been discussed to death and back.

Hi,

obliviux : If you also feel like sharing some bits of code that demonstrate how to use .NET features in unityscript ( or js ), please do so, we all need as much help as possible.

NPSF3000 :

Eric5h5: FTFY has a double meaning... ( Those evil C# coders again )...

Aubergine : Indeed, it is more about personal preference IMHO too.

 

thanks for this. It really helped me with getting WatchVar in DebugConsole work https://gist.github.com/darktable/1412228

 

Hi,
Looks really useful, thanks for sharing.
