What exactly does sendBlockChange() do?

Pretty straightforward question. Can someone please explain to me in a way that an idiot (me! =D) could understand? Thanks!

 

It sends a block change to the client which didn't happen, in other words fakes a block change.

 

Then should the client see the block change but no one else will?

 

yes

 

That is nice for invisible jails and such

 

I tried doing an onPlayerInteract() and an if statement to check if the event was a Block Right-click, then

event.getPlayer().sendBlockChange(event.getClickedBlock().getLocation, 7, (byte) 0)

But when I right-clicked a block, nothing happened. Am I just incompetent?

 

Did you register the event?

 

Yes, I registered onPlayerInteract()

 

No idea then. Could we check out the source code?

 

Yup, here ya go:

Code:

public void onPlayerInteract(PlayerInteractEvent event){
    if(event.getType() == RIGHT_CLICK_BLOCK){
        event.getPlayer().sendBlockChange(event.getClickedBlock().getLocation(), 7, (byte) 0);
    }
}

That's it.

 

As far as I can see, there is no Event.Type of RIGHT_CLICK_BLOCK. I use the same event for a different cause and I determine the players action like this:

Code:

@Override
public void onPlayerInteract(PlayerInteractEvent event){
  if( event.getAction() == Action.RIGHT_CLICK_BLOCK ){
    doSomething();
  }
}

event.getType() will probably return ENTITY_INTERACT.

 

That's it! zeff has definitely got the answer there. The type will return Event.Type.PLAYER_INTERACT.

 

Sorry, I meant to type Action.RIGHT_CLICK_BLOCK after event.getType(). I typed that outside of an IDE, so I messed that one up.

Anyway, it still doesn't work. Should I be sending it a Block instead of a Location?

 

Can you post your entire source? Are you sure you registered your event with the PluginManager?

 

It's because you are using event.getType(), which does return an Event.Type-constant (PLAYER_INTERACT) and NOT the action of the PlayerInteract-event. Test Action.RIGHT_CLICK_BLOCK against event.getAction().

 

That is what I did. I messed up when I typed that code, so here it is again:

Code:

    public void onPlayerInteract(PlayerInteractEvent event){
        if(event.getAction() == Action.RIGHT_CLICK_BLOCK){
            event.getPlayer().sendBlockChange(event.getClickedBlock().getLocation(), 7, (byte) 0);
        }
    }

And inside the main class:

Code:

    private final NPCTestPL pl = new NPCTestPL(this);
    public void onEnable(){
        PluginManager pm = this.getServer().getPluginManager();
        pm.registerEvent(Event.Type.PLAYER_INTERACT, pl, Event.Priority.Normal, this);
    }

It's called NPCTest because that was the original point of that project for about 5 minutes, then I decided to try this.
