Issues with .link()

[Twinny]

Hey guys,

I'm trying to use .link() in a script i'm working on. I would assume it would work like this,

PHP Code:

function onCreated() {
  this.number = 5;
  temp.clone = this.number;
  temp.clone = 10;
  printf("this.number = %i", this.number); //Outputs 5
  printf("temp.clone = %i", temp.clone); //Outputs 10
  echo("--------");
  temp.link = this.number.link();
  printf("temp.link = %i", temp.link); //Outputs 5
  temp.link = 20;
  printf("this.number = %i", this.number); //Outputs 5 -- Expected 20?
  printf("temp.clone = %i", temp.clone);  //Ouputs 10
  printf("temp.link = %i", temp.link);  //Outputs 20
} 


I also tried a different example,

PHP Code:

function onCreated() {
  this.num1 = 1;
  this.num2 = 2;
  this.array = {this.num1.link(), this.num2.link()};
  printf("Pre-Change: %s", this.array);
  
  for (i=0; i<2; i++)
    this.array[i] = 20;
  
  printf("Post-Change: %s", this.array);
  
  echo("this.num1 = " @ this.num1);
  echo("this.num2 = " @ this.num2);
}

Pre-Change: 1,2
Post-Change: 20,20
this.num1 = 1
this.num2 = 2 


This was tested on Testbed.

I would have thought temp.link = this.number.link(); would make temp.link reference this.number rather than copying the object but the output shows opposite.

Is .link() supposed to be returning a reference or is it providing another use?

As per Stefan,

Assignments are always resolving links, the link() function is more
for passing complex variables to functions

He suggested TStaticVars which could get around my array issue like this,

PHP Code:

function onCreated() {
  temp.obj1 = new TStaticVar();
  temp.obj1.num = 1;
  
  temp.obj2 = new TStaticVar();
  temp.obj2.num = 2;
  
  temp.array = {temp.obj1, temp.obj2};
  temp.array[0].num = 5;
  echo(temp.array[0].num); //Outputs 5
  echo(temp.obj1.num); //Outputs 5

  temp.obj1.destroy();
  temp.obj2.destroy();
} 


It works but is definitely not what I had desired.
