[Tutorial] Creating your own custom border limit and border message

This tutorial is for all the plugin developers out there that like to keep their server as custom as it can get.

I'm going to explain to you how you can create your own border limit and message.

An example;

Code:java

 @EventHandler
public void onMove(PlayerMoveEvent e)
{
Player p = e.getPlayer();
if (e.getTo().getX() > 3000 || e.getTo().getX() < -3000 || e.getTo().getZ() > 3000 || e.getTo().getZ() < -3000)
{
e.setTo(e.getFrom());
p.sendMessage("You wandered out too far!");
}
 
}

Explained;

The plugin disallows the player to walk past X: 3000, X: -3000, Z: 3000, Z:-3000

Broken down;

Code:java

if (e.getTo().getX() > <intXOfChoice> 

The plugin is checking if the X location is greater than the number of which you will declare to ensure the player cannot walk any further. If the X location is greater than the number, then;

Code:java

e.setTo(e.getFrom());

The player is teleported back to where they originally were, and therefore a border is created.

When the player is teleported back, you can add in a custom message for them by simply sending them a message of your choice like I showed you in the example.

If you have any questions, let me know and I'll try my best to answer them.

 

So with this, is it from the spawnpoint or coords?

 

The event checks the players' X and Y co-ods.

 

• p.sendMessage(p.sendMessage("You wandered out too far!");
• Shouldn't that be just
  p.sendMessage("You wandered out too far!");
  
  

 

Okey, good to know, will make sure the spawnpoint of my server is at 0

 

Yeah, didn't mean to do that, fixed.

 

You'll want to do much more for a true border plugin. See WorldBorder.

• Boats?
• Minecarts?
• Enderpearls?
• Nether portals?
• Using a scheduled task instead of the move event is also an option to reduce lag.

 

Hmmm, they will be some problems... But every problem has a fix, I'll work on these asap.
