Solved How can I give an effect on an area range

I have been working on a plugin but I have the doubt, If I have a command "/test" for example, and I want the player to put "/test", grant "regeneration" or some enchantment, to each player near the in 5 blocks for example, how could I do this in my plugin? , or if I can at least do it.

 

Foreach all the online players then check if he is 5 blocks nearby.

 

Some example?

 

or if you want to give effect in a square you can youse this code:

PHP:

public function onMove(PlayerMoveEvent $event){
        $nextPos = $event->getTo()->asVector3();
        $x = $nextPos->getX();
        $z = $nextPos->getZ();
        if ($x1 /*first X*/ > $x2 /*second X */){
            if ($z1 /*first Z*/ > $z2 /*second Z*/){
                if ($x1 > $x and $x < $x2){
                    if ($z1 > $z and $z < $z2){
                        //add effect...
                    }
                }
            }else{//Z1 < Z2
                if ($x1 > $x and $x < $x2){
                    if ($z1 < $z and $z > $z2){
                        //add effect...
                    }
                }
            }
        }else{//X1 < X2 or X1 = X2
            if ($z1 /*first Z*/ > $z2 /*second Z*/){
                if ($x1 < $x and $x > $x2){
                    if ($z1 > $z and $z < $z2){
                        //add effect...
                    }
                }
            }else{//Z1 < Z2
                if ($x1 < $x and $x > $x2){
                    if ($z1 < $z and $z > $z2){
                        //add effect...
                    }
                }
            }
        }
    }

 

PHP:

$player = Player;
foreach($player->getServer()->getOnlinePlayers() as $onlinePlayer) {
    if($player->distance($onlinePlayer->asVector3()) <= 5) {
        $onlinePlayer->addEffect(new EffectInstance(Effect::getEffect(Effect::REGENERATION)));
    }
}


 

its laggy for server, its not best way

 

Oh How can I avoid lag?

 

It won't lag

 

its laggy on lower vps :L

 

just befor add effect check if player dosnt have that effect, and then give it to player, its better

 

No, it isn't. Check it by yourself.

 

i dont have vps with 128mb ram, please check it your self please, ik its laggy

 

And how can I add time to the effect?

 

Hello @Znightmare123 ,

PHP:

$GodWeedZao =
new EffectInstance(Effect::getEffect(Effect::NAME), TIME* 20, 1, true);
//NAME => name of effect
//TIME => time to add effect in player
$player->addEffect($GodWeedZao);
