using EntityDamage to set a knockback

Hey, today I wanted to see if this is a way that I can actually make this function work. Would actually doing this work? I dont have a server to test this on so thats why I am asking i want to get it done by the time I get a test server. Thanks also what does the “z” do? I just set it the same to the x cause I heard they are the same thanks heres my code:

PHP:

class Main extends PluginBase implements Listener{

  public function onEnable() {
     $this->getServer()->getPluginManager()->registerEvents($this,$this);      
  }

  $mot = new Vector3($this->motionX, $this->motionY, $this->motionZ);
 
  $mot->x = 0.3;
  $mot->y = 0.5;
  $mot->z = 0.3;//UNSURE OF THIS HELP?
 
  public function onDamage(EntityDamageEvent $daddy) {
    if($daddy instanceof EntityDamagebyEntityEvent){
      $event-setMotion($mot);
    }
  }
}


 

Naming the event daddy and then using event anyways won’t work. Also setMotion isn’t what you want, you want setKnockback (setMotion is only availible for Entities anyways. Also your $mot variable declaration is out of scope.

PHP:

class Main extends PluginBase implements Listener{

  public function onEnable() {
     $this->getServer()->getPluginManager()->registerEvents($this,$this);     
  }

  public function onDamage(EntityDamageByEntitiyEvent $daddy) {
      $daddy->setKnockback(0.5);
  }
}


 

I made that exact plugin a couple weeks ago but I want to use setMotion so that I can change the x and y values diffrently. Can you help me find a way?

 

If you want to use setMotion it has to look like this:

PHP:

class Main extends PluginBase implements Listener{

  public function onEnable() {
     $this->getServer()->getPluginManager()->registerEvents($this,$this);   
  }

  public function onDamage(EntityDamageByEntitiyEvent $daddy) {
      $daddy->getEntitiy()->setMotion(new Vector3(0.3,0.5,0.3));
  }
}


 

Oh okay, now I understand. Thanks dude!
