Find the packet in Minecraft's source code. Minecraft's packets are in the `net/minecraft/network/protocol/<state>` directory. The state for your packet is usually `game`. -2. Add a new file in the [`packets/<state>`](./src/packets/game) directory with the snake_cased version of the name Minecraft uses. -3. Copy the code from a similar packet and change the struct name. -4. Add the fields from Minecraft's source code from either the read or write methods. -If it's a `varint`, use `#[var] pub <name>: i32` (or u32 if it makes more sense). -If it's a `varlong`, use `#[var] pub <name>: i64` (or u64). -If it's a byte, use i8 or u8. -Etc.. You can look at [wiki.vg](https://wiki.vg/Protocol) if you're not sure about how a packet is structured, but be aware that wiki.vg uses different names for most things. -5. Add the packet to the `mod.rs` file in the same directory. You will have to look at [wiki.vg](https://wiki.vg/Protocol) to determine the packet id here. -6. That's it!
