Effects when killing a partner

How can I make a player kill a member of his team have effects?
can you help me. Here is my code!
public function onDeathEffect(PlayerDeathEvent $event){
$jugador = $event->getEntity();
$mapa = $jugador->getLevel()->getFolderName();
if(in_array($mapa,$this->arenas))
{
$event->setDeathMessage("");
if($event->getEntity()->getLastDamageCause() instanceof EntityDamageByEntityEvent)
{
$asassin = $event->getEntity()->getLastDamageCause()->getDamager();
$config = new Config($this->getDataFolder() . "/config.yml", Config::YAML);
if($config->get($mapa . "PlayTime") != null)
{
if($config->get($mapa . "PlayTime") > 779)
{
$event->setCancelled();
}
if ((strpos($jugador->getNameTag(), "§l§6ANONYMAUS") !== false) && (strpos($event->getDamager()->getNameTag(), "§l§6ANONYMAUS") !== false)) {
$event->setCancelled();
$asassin->sendMessage("§aHas Matado A Un Inocente");
$nause = Effect::getEffect(9);
$natus = Effect::getEffect(18);
$nause->setVisible(true);
$natus->setVisible(true);
$nause->setAmplifier(1);
$natus->setAmplifier(1);
$nause->setDuration(100);
$natus->setDuration(100);
$asassin->addEffect($nause);
$asassin->addEffect($natus);
$assassin->getInventory()->clearAll();
}
elseif ((strpos($jugador->getNameTag(), "§f§l§6ANONYMAUS§f§6") !== false) && (strpos($event->getDamager()->getNameTag(), "§f§l§6ANONYMAUS§f§6") !== false)) {
$event->setCancelled();
} } } } }

 

Elaborate please!

 

Use PHP tags to format code, i can barely read what is in there :/

 

Yeah, they are there for a reason

 

So do you want an effect that plays when a player teamkills their teammate? We need to know How do you define teams first though

 

Ok here ill do it for you:

Give me some time to properly organise and read your code then ill try and see what i can do

PHP:

public function onDeathEffect(PlayerDeathEvent $event){
$jugador = $event->getEntity();
$mapa = $jugador->getLevel()->getFolderName();
if(in_array($mapa,$this->arenas))
{
$event->setDeathMessage("");
if($event->getEntity()->getLastDamageCause() instanceof EntityDamageByEntityEvent)
{
$asassin = $event->getEntity()->getLastDamageCause()->getDamager();
$config = new Config($this->getDataFolder() . "/config.yml", Config::YAML);
if($config->get($mapa . "PlayTime") != null)
{
if($config->get($mapa . "PlayTime") > 779)
{
$event->setCancelled();
}
if ((strpos($jugador->getNameTag(), "§l§6ANONYMAUS") !== false) && (strpos($event->getDamager()->getNameTag(), "§l§6ANONYMAUS") !== false)) {
$event->setCancelled();
$asassin->sendMessage("§aHas Matado A Un Inocente");
$nause = Effect::getEffect(9);
$natus = Effect::getEffect(18);
$nause->setVisible(true);
$natus->setVisible(true);
$nause->setAmplifier(1);
$natus->setAmplifier(1);
$nause->setDuration(100);
$natus->setDuration(100);
$asassin->addEffect($nause);
$asassin->addEffect($natus);
$assassin->getInventory()->clearAll();
}
elseif ((strpos($jugador->getNameTag(), "§f§l§6ANONYMAUS§f§6") !== false) && (strpos($event->getDamager()->getNameTag(), "§f§l§6ANONYMAUS§f§6") !== false)) {
$event->setCancelled();
} } } } }

Edit: Oh crap its spanish this will take some time
