Question

I am looking at Should I use multiple classes for game? – Robert Pitt’s answer.

interface Weapons {

    public function Fire();

}

class Colt implements Weapons {

    function Fire() {
        echo 'Fire!';
    }

}

abstract class Human implements Colt
{

}

class Sniper extends Human
{
    public function __construct()
    {

    }



}

On the “Human” am I perhaps to implement the “Weapons” rather then Colt, and then on the “Sniper” initialize the Right weapon class?

class Sniper extends Human
{
public $weapon;

    public function __construct($weapon)
    {
    $this->weapon = new $weapon;  
    }


$this->weapon->fire();


}

Or something like that? I am confused of how it works..

EXAMPLE 1

class A {
public $class;

__construct() {
$this->class = new $class;
}

hello() {
$this->class->hello();
}
}

class B {
public function hello() {
echo 'hi';
}
}

It’s up to you, how will you design your classes.

If I would be a game programmer, I’d probably use something like (it’s a working minigame!)

<?php
class Fight {
     public $weapon;
     public $name;
     public function __construct($weapon, $name)
     {
        $this->name = $name;
        $this->weapon = new $weapon;
     }
     public function fire($person) {
         $this->weapon->fire($person);
     }
     public function changeWeapon($weapon) {
        $this->weapon = new $weapon;
     }
}

class Sniper extends Fight {   }
class Terrorist extends Fight {   }

class MauserSniper {
     function fire($person) {
         echo "Firing $person->name! Miss! Your rifle is damaged<br />";
     }
}

class AK47 {
     function fire($person) {
         echo "Firing $person->name! Hit with AK47!<br />";
     }
}


class SteyrSSG {
     function fire($person) {
         echo "Firing $person->name! Hit!<br />";
     }
}

$sniper1 = new Sniper("MauserSniper", "Martin");
$sniper2 = new Sniper("SteyrSSG", "Daniel");
$terrorist = new Terrorist("AK47", "Mike");
$sniper1->fire($sniper2); //we'll miss this one.
$sniper1->changeWeapon("SteyrSSG");
$sniper1->fire($sniper2); //hit!
$terrorist->fire($sniper1);
