On player changes block

Hello guys,

I’m trying to execute some code each time a player moves from one block to another, only horizontally (if x or z changes). So I came up with this but it’s not working as I expected. Is there any mistake in this or does it come from the following operations (in which case I’ll take care of) ?

@Listener
public void onPlayerMove(DisplaceEntityEvent event, @First Player player)
{
    if (event.getFromTransform().getLocation().getBlockPosition().getX() == event.getToTransform().getLocation().getBlockPosition().getX() && 
            event.getFromTransform().getLocation().getBlockPosition().getZ() == event.getToTransform().getLocation().getBlockPosition().getZ())
    {
        return;
    }
    Location<World> loc = player.getLocation();
    
    // and then do some stuff
}

This only works if player moves vertically I think…Nevermind…

I would change DisplaceEntityEvent to DisplaceEntityEvent.TargetPlayer

and .getBlockPosition().getX() to .getBlockX() and so on

Not a bad idea. I did so but the problem is still there.

After getting the location, I test wether the player enters (or leaves) a special zone, if so I send him a message. And here it’s as if the message is always “one block too late”.

Any idea ? :confused:

I’m not sure. I guess it would depend on how you’re storing the information for that zone.

Well it works when I remove the first if so I assume the problem does not come from the “is inside zone” testing.

Shouldn’t that be event.getToTransform()? Otherwise the location will be where the player was and not where their going.

Oh yeah you’re right ! Thanks !

That solved my problem… well partially but the other part is probably due to the rest of my code. I’ll search by myself :wink:

Another question that is a bit related. In a totally different context, is it possible to, how could I say, like reduce the frequency at which the DiplaceEntityEvent is called (only for this listener of course, not globally) ?

I did that with a Hashtable<UUID, Date> lastChecks but is there a short and easy “built-in” way ?

I’m not aware of a built in way, you’ll have to handle that yourself.

Ok, thanks anyway !
