Question by Facepalm · Jan 28, 2012 at 06:32 AM · javascriptreferenceinterfaceabstract

Some JavaScript questions

Since I never had close contact with javascript I would like to clarify some aspects:

  1. Whenever I'm assigning new instance of an object to a variable does the previous object is deleted as it happens in java (with help of garbage collector)?

  2. Can I declare a class as abstract one and there are interfaces in javascript? If the answer is yes then give me a little example, please. Just to see its syntax..

If you want good documentation, and interfaces and abstract classes, you should use C# ins$$anonymous$$d of javascript. Co$$anonymous$$g from a java background, C# will be more familiar to you, and there is much more documentation and knowledge out there about C# than there is about UnityScript. The Javascript implementation that is used in Unity is unique, so the only places where there is any information about it are Unity-specific.

  1. I am not 100% sure here, I haven't really dived into the UnityScript engine as of yet, but in Javascript and Actionscript 3 (both of which are based off of the ECMA Script standard), objects which have no references to them (orphaned variabled) are removed (or queued for removal) by the garbage collector; so I assume that it is the same here with UnityScript.

  2. As syclamoth stated, UnityScript is a unique version of Javascript (though it is closest to using the ECMA Script 4 standard -- the same on that Actionscript 3.0 uses). You can create interfaces though, and it is pretty much exactly the same as in Java. Here is a quick interface example for UnityScript:

public interface MyInterface{
   function GetMyName():String;
}

To implement the interface you also do it like in Java:

class MyClass inplements MyInterface{
   public function GetMyName():String{
     return "BetaWar";
   }
}

Hopefully that helps.
