Fires when an entity is removed (for example, potentially unloaded, or removed after being killed).

// Script by WavePlayz

import { system, world } from "@minecraft/server";

// Subscribe to the entityRemove event, which is triggered when an entity is removed from the world
world.afterEvents.entityRemove.subscribe((eventData) => {
// Extract the type ID of the removed entity from the event data
const { typeId } = eventData;

// Send a message to all players in the world indicating that an entity of the given type has been removed
world.sendMessage(`Entity ${typeId} got removed`);
});

/*
Explanation:
This script listens for the `entityRemove` event, which occurs when an entity is removed from the Minecraft world.

- **Event Subscription**:
The `world.afterEvents.entityRemove.subscribe` method registers a callback function to handle the event whenever an entity is removed.

- **Extracting Entity Type**:
The `typeId` property from the `eventData` object contains the identifier of the removed entity's type.

- **Sending a Message**:
The script constructs a message indicating which type of entity was removed and sends this message to all players in the world using `world.sendMessage`.

Usage:
When an entity is removed (e.g., due to despawning, being killed, or otherwise removed), this script will automatically notify all players in the game with a message stating the type of the removed entity.
*/

This event fires when an entity is spawned.

// Script by WavePlayz

import { world } from "@minecraft/server";

// Subscribe to the gameRuleChange event, which is triggered when a game rule is updated
world.afterEvents.gameRuleChange.subscribe((eventData) => {
// Extract the game rule name and its new value from the event data
const { rule, value } = eventData;

// Send a message to all players in the world indicating that a game rule has been updated
world.sendMessage(`Gamerule ${rule} updated to ${value}`);
});

/*
Explanation:
This script listens for the `gameRuleChange` event, which occurs when a game rule is modified in Minecraft.

- **Event Subscription**:
The `world.afterEvents.gameRuleChange.subscribe` method registers a callback function to handle the event whenever a game rule changes.

- **Extracting Information**:
- `rule` provides the name of the game rule that was changed.
- `value` indicates the new value of the game rule.

- **Sending Notification**:
- The script constructs a message that includes the name of the updated game rule and its new value, then sends this message to all players in the world using `world.sendMessage`.

Usage:
When a game rule is changed, this script automatically notifies all players with a message that includes the name of the updated game rule and its new value. This is useful for tracking changes to game rules and keeping players informed about the current game settings.
*/

This event is fired after an explosion occurs.

import { world } from "@minecraft/server";

// Subscribe to the ExplosionAfterEvent
const explosionSubscription = world.afterEvents.explosion.subscribe((event) => {

if (event.source) {
console.log(`Explosion source: ${event.source.typeId}`);
} else {
console.log(`Explosion source: None`);
}

const impactedBlocks = event.getImpactedBlocks();
console.log(`Impacted blocks: ${JSON.stringify(impactedBlocks)}`);

// ... Later in your code, when you want to unsubscribe
world.afterEvents.explosion.unsubscribe(explosionSubscription);

This event fires when a world.gameRules property has changed.

This event fires when a chargeable item completes charging.

// Script by WavePlayz

import { world } from "@minecraft/server";

// Subscribe to the itemCompleteUse event, which is triggered when a player completes using an item
world.afterEvents.itemCompleteUse.subscribe((eventData) => {
// Extract the player who used the item and the item stack from the event data
const { source, itemStack } = eventData;

// Construct a message indicating the player's name and the type of item they used
world.sendMessage(
`Player ${source.name} completed use of item (${itemStack.typeId})`
);
});

/*
Explanation:
This script listens for the `itemCompleteUse` event, which occurs when a player finishes using an item in Minecraft.

- **Event Subscription**:
The `world.afterEvents.itemCompleteUse.subscribe` method registers a callback function to handle the event whenever an item use is completed.

- **Extracting Information**:
- `source` represents the player who used the item.
- `itemStack` provides details about the item stack, including its type ID.

- **Sending Notification**:
- The script constructs a message that includes the player's name and the type ID of the item they used. This message is then sent to all players in the world using `world.sendMessage`.

Usage:
When a player completes using an item (such as consuming a potion or using a tool), this script sends a notification to all players in the game, indicating which player used which item. This can be useful for tracking item usage or for general game management.

When the event is triggered:
- It retrieves the player who hit the block (`source`) and the location where the block was hit (`hitVector`).
- It formats the location coordinates and constructs a message with the player's name and coordinates.
- It then sends this message to all players in the world, so everyone knows who hit a block and where.
