Examples with Snapshot buildcraft.builders.snapshot.Snapshot used on opensource projects

Example 6 with Snapshot

use of buildcraft.builders.snapshot.Snapshot in project BuildCraft by BuildCraft.

the class TileElectronicLibrary method writePayload.

// How networking works here:
// down:
// 1. server sends NET_DOWN with snapshot to clients
// 2. clients add snapshot to their local database
// up:
// 1. server sends empty NET_UP to clients
// 2. client who have selected snapshot sends NET_UP with it back to server
// 3. server adds snapshot to its database
