⏳ Delays

Use the delay(ticks, () -> { ... }) function to delay execution.

• 1 second = 20 ticks

delay(40, () => {
  msg($player, "This message appears after a 2 seconds delay.");
});

📦 Importing Java Classes

You can import external classes using the import keyword with quotes:

import "org.bukkit.Bukkit";
import "org.bukkit.entity.LivingEntity";
import "net.kyori.adventure.text.Component";
import "com.comphenix.protocol.ProtocolLibrary";

❌ Cancelling The Event

You can cancel the current event using:

cancelEvent();

💬 Messaging and Logging

log(String message);

↺ Casting

Exactly how it works in Java.

Type1 item = (Type2) item2;

📌 Best Practices

• Use delay() for animations or delayed feedback.

• Always check isCustom() before modifying custom items or blocks.

• Log actions with log() during debugging.

• Use cancelEvent() to prevent default behavior when handling interactions.

Example code

Replace near custom blocks.

cancelEvent(); // Cancel the event to prevent further processing

var location = $player.getLocation();
var count = 0;

// Iterate through all blocks in a 10x10x10 cube around the player and check isCustom(block) == true
for (var x = -5; x <= 5; x++) {
  for (var y = -5; y <= 5; y++) {
    for (var z = -5; z <= 5; z++) {
      var block = location.getWorld().getBlockAt(location.getBlockX() + x, location.getBlockY() + y, location.getBlockZ() + z);
      if (isCustom(block)) {
        msg($player, "Found a custom block at " + block.getLocation().toString());
        placeBlock(block, "minecraft:stone");
        count++;
      }
    }
  }
}

// Send a message to the player indicating that the script has finished running
msg($player, "Replaced " + count + " custom blocks with stone blocks.");
