Class joining bug/undocumented feature

[WhiteDragon]

This is the code I am executing:

-whitedragon_system

PHP Code:

new TStaticVar("Movement").join("whitedragon_system_movement");
new Movement("NormalMovement").join("whitedragon_system_movement_normal");
this.movement = new NormalMovement().construct(); 


whitedragon_system_movement

PHP Code:

public function construct() {
  echo("----------");
  echo(this.joinedclasses);
  echo(this.getfunctions());
  for(f : this.getfunctions())
    echo(f SPC f.scope);
  echo("----------");
  return this;
} 


whitedragon_system_movement_normal

PHP Code:

public function construct() {
  echo("movement_normal");
  return this;
} 


The code that you see in whitedragon_system_movement is some debugging code to see exactly what functions exist and what is getting over written.

I get the following output:

That's handful, so I'll sum it up for you:

• echo(this.getfunctions()) echos "construct" twice.
• The loop echos "construct" once.
• It doesn't finish the block of code (there are no ending dashes echoed).

This behavior is getting so weird, I had no idea what was going on.
Even speculation would be helpful.

Thank you.

Your object creation syntax is horrible, please do it properly just in the interest of eliminating all possibilities in error.

And having two construct echoed is not surprising.
Its possible to do <classname>::<functionname>(); if two classes have same function.

I would highly suggest avoiding situations where functions overwrite like that.

PHP Code:

function thefunction() {
  temp.var = new TStaticVar("Movement");
  temp.var.join("whitedragon_system_movement");
  temp.var = new Movement("NormalMovement");
  temp.var.join("whitedragon_system_movement_normal");
  this.movement = new NormalMovement();
  this.movement.construct();
}
