NetworkEvent
NetworkEvent is used for sending and receiving data between the server and client. This is particularly useful when you need to synchronize information or trigger cross-side operations.
Sending Data
To send data, use the sendData method:
d.ts
sendData(channel: string, data: Internal.CompoundTag_): void;Parameters:
channel: A string that identifies the data channel. The receiving end will use this name to listen for data.data: A CompoundTag type containing the data to be transmitted.
Example: Sending data about the player's main hand item to the server when the player types in the chat:
js
PlayerEvents.chat(event => {
const { player } = event
const mainHandItem = player.getMainHandItem();
player.sendData('item_sync', { item: mainHandItem.getId() })
})Receiving Data
To receive data, use the NetworkEvents.dataReceived event:
js
const ItemStack = Java.loadClass('net.minecraft.world.item.ItemStack')
NetworkEvents.dataReceived('item_sync', event => {
const itemId = event.data.get('item')
const item = new ItemStack(itemId)
Client.gameRenderer.displayItemActivation(item)
})This example demonstrates how to receive data on the 'item_sync' channel on the client side and display the corresponding item.
Important Considerations
- Ensure that the sending and receiving sides use the same channel name.
- Data transmission should be as concise as possible, only sending necessary information.
- When handling received data, consider cases where the data might not exist or could be in an incorrect format.
By effectively using NetworkEvent, you can implement complex cross-side interaction features.
