JS pass array by value and not reference

Unity Engine
1

Ok so I am trying to send an array to multiple game objects, but when they get it they get it by reference.

This is the basic code;

public var MyTime : Array = new Array( Vector3(0,0,0));

GNPC[i].SendMessage("Data", MyTime);

function Data(X : Array){
	MyTime=X;
}

I am trying to make some kind of ghost which moves exactly as you do, I save X and Y for Horizontal Vertical axes while Z is time. (just if you are trying to figure out why I want to send the message)

You should never use the Array class; it’s slow and untyped. Use built-in arrays or generic Lists. In this case you don’t appear to need an array at all, but if you did, you can use System.Array.Copy for built-in arrays in order to make a copy. Also, use lowercase for variable names; uppercase is for classes and methods.

Thanks for the tip about the variable names.
An array is that slow? I ask because it was the easiest solution I thought.

From what I asked I also found the method slice(0); which makes a new array :slight_smile:

MyTime=X.slice(0);

I will start using lowercase variables and will look into Lists

There’s no reason to use it. It’s slower, has fewer features, and is more difficult to use if you’re using #pragma strict (which you really should be) since you have to cast to the correct type.
