onTap

With tap on a certain block is not the subject of a certain (not coal for e.g) will be written in chat "tap whith the coal." How to do it ?

you can use PlayerInteractEvent.

Learn PHP ._.

PHP:

public function onTap(PlayerInteractEvent $event){
if(!$event->getBlock() === Block::/*block*/){
//CODE
}
}

And here php? So I just do not understand. It is as though a PM API is .-. And about the PM API then ask apparently cancelled ?

no, i know you can check if it is, but if you know PHP You would write ! (not equal to) it's PHP.

I tried to do it, but it did not and that's why I asked here ... I'm not a great programmer and a novice.

You're comparing object with an integer wont work always will return false!
fix

PHP:

if(!$event->getBlock->getId() === Block::/* block *.)


Learn PHP yourself.

Why don't you simply use !== ?
