Devlog: how crossplay actually works now

Devraj · GameplayJul 4, 202611 min read

Java and Bedrock players share lobbies, ladders and chat. Getting there took a proxy rewrite and a lot of humility.

The short version: we stopped trying to make Bedrock behave like Java and started translating intent instead of packets.

What broke first

Inventory. Always inventory. Bedrock and Java disagree about when a slot is authoritative, and our old proxy took Java as truth, which meant Bedrock players lost items on every kit swap.

This is a long technical post. If you just want to know whether your friend on Switch can play with you: yes, same IP, port 19132.
