Question

I am making a game, and came to the part to implement character abilities on the server-side.

So I have an array to hold all character abilities:

$abils = array();

And a class for them:

class Abil{
    private $timing;
    private $func;

    public function __construct($time, $func){
        global $abils;
        $this->timing = $time;
        $this->func = $func;
        array_push($abils,$this);
    }

    public function trigger($time,$params){
        if(preg_match('/^'.$this->timing.'$/',$time)) $this->func($params);
    }
}

$time is the “timing” of the ability, as RegEx. For example, \d\d-0 would be the start of anyone’s turn.
$func is a function to run when the ability is used.

When a certain “timing” is reached (for example, the start of someone’s turn), a global triggerAll() function would be used to trigger all abilities of that timing:

function triggerAll($time,$params = NULL){
    global $abils;
    foreach($abils as $abil) $abil->trigger($time,$params);
}

But then, when triggerAll is called, a fatal error is generated:
Fatal error: Call to undefined method Abil::func()

I suspect this is due to $func not being a METHOD but a PROPERTY which holds a function. Any workarounds?

Answer 1

Found a workaround: call_user_func

call_user_func($this->func,$params);

instead of

$this->func($params);
