Setting the server name (On F3 screen)

[SeseMueller]

Reproduction

I entered any playground and pressed F3. On the third line, it says "null" for the server brand/name.

This can however be solved quite easily:

The server name can be set i.E. to "Valence".

fn init_clients(
    mut clients: Query<
        (
            &mut EntityLayerId,
            &mut VisibleChunkLayer,
            &mut VisibleEntityLayers,
            &mut Position,
            &mut GameMode,
            &mut Client,
        ),
        Added<Client>,
    >,
    layers: Query<Entity, (With<ChunkLayer>, With<EntityLayer>)>,
) {
    for (
        mut layer_id,
        mut visible_chunk_layer,
        mut visible_entity_layers,
        mut pos,
        mut game_mode,
        mut client
    ) in &mut clients
    {
        let layer = layers.single();

        layer_id.0 = layer;
        visible_chunk_layer.0 = layer;
        visible_entity_layers.0.insert(layer);
        pos.set([0.0, SPAWN_Y as f64 + 1.0, 0.0]);
        *game_mode = GameMode::Creative;

        // The payload is a &[u8] whose first byte is the length of the string 
        // followed by the string itself.
        let payload = [7, b'V', b'a', b'l', b'e', b'n', b'c', b'e'];

        client.send_custom_payload(ident!("minecraft:brand"), &payload);
    }
}

The send_custom_payload function with channel "minecraft:brand" can set the server name to any payload.

Now what

The question is whether this should be set at all/ be turned into a plugin/ etc.

I'd be glad to turn it into a tiny plugin.

I'd make an extension trait for this and put it in crates/valence_server/src/brand.rs.

pub trait SetBrand {
    fn set_brand(&mut self, brand: &str);
}

impl<T> SetBrand for T where T: WritePacket { ... }
