Attack

Play 0x01, client → server.

play · 0x01 · serverbound (client → server)

Sent when the player attacks (left-clicks) an entity with numeric entityId. The server checks reach and validity, then applies damage. This replaces the attack case of Interact; it usually comes with a Swing.

Sent by the client, read by the server. Listen for it with client.on("Attack", (data) => …) on the receiving side.

Fields
