Directions.. Need help

Okay, so I'm trying to make a border plugin where if a player tries to walk out of the border it knocks them away from it. How can I get the direction that the player is facing in and how do I get the opposite of that..

Player::getDirection()

You could take a look at LeetBorder...

No I couldn't, that teleports players back, it doesn't knockback

Using Player::getDirection() is bad practice as you are statically accessing the Player. Instead you should use $event->getPlayer()->getDirection();

That is an example...

To knock a player a player to his back, use $player->getDirectionVector();

PHP:

// on border event
 $player->setMotion($player->getDirectionVector()->multiply(-2));



Yes, it was an example. But he gave an incorrect example.

But everyone knows what he means?

I don't see a problem with me correcting him. He should've just done it the right way.

I also use $player it reprents the same as Player - objects.

You need to get the player from the event...

No you don't. Also, Player::functionName is just a way of showing a function. I believe getDirection cannot be statically used on Player object.

Also, nobody said it has to be $event->getPlayer()...

Sorry, I'm getting things mixed up with the MiNET API . I thought he was saying to use it statically, that's why I was correcting him.

Undefined variable $event. Who gives the wrong examples? Please go and check what Player::getDirection() means. I am pointing on the function getDirection() in the Player class. Doesn't matter what player event, $event->getPlayer() returns a Player.

If you knew where to put event then it would work

You don't "put event" somewhere.
