Hi, i’ve tried to convert this c# script to javascript but i couldn’t i’d be very happy if u helped me :slight_smile:

this is the code

using UnityEngine; 
using System.Collections; 
using System.Collections.Generic; 

public class DropList : MonoBehaviour 
{ 
    public class GuiListItem
    { 
        public bool BigBool; 
        public string BigString; 
        public GuiListItem(bool myBool, string myString) 
        { 
            BigBool= myBool; 
            BigString= myString; 
        } 
        private List<GuiListItem> MyListOfStuff;
    }
}

You should remove the spaces in the code to make it easier to read.

As I think you learn better when you do it yourself, I won’t translate the code, but here are some rules :

  • you don’t have the using …; in javascript
  • javascript is by default a class inherited from Monobehaviour, you don’t need to declare it. However, it’s good to know that inheritance declaration is done with extends, not :.
  • variables declarations. Private by default in C#, they are public in javascript. they are declared that way : C# [access level] [scope (static, const, local)] [type] [name]; JS [access level][scope] var [name] : [type]. Note that this comes from my experience, that’s probably not the name people give them.
  • to declare a function, begin with function and end with :[return type], if there is any.

This conversion isn’t trivial, because uses List and class declaration. I didn’t test this, but from other cases I think it should be written this way:

import System.Collections.Generic.List;

class GuiListItem { 
    var BigBool: boolean; 
    var BigString: String ; 
    function GuiListItem(myBool: boolean, myString: String){ 
        BigBool= myBool; 
        BigString= myString; 
    } 
}

// I suppose MyListOfStuff isn't part of the GuiListItem class, since it's a list
// of GuiListItem, thus I moved it out of the class declaration. If I'm right,
// declare and initialize this list in your code like this:
private var MyListOfStuff: List.<GuiListItem> = new List.<GuiListItem>;

As @Berenger said, in UnityScript you don’t need the using lines and the script class declaration - the compiler adds them internally. Only System.Collections.Generic.List must be declared with import, because it’s not automatically included.
