the spawn log caught it at once: two archers took 11 and 12, and the goblins that followed started again at 12, then the knight landed on 13. the counter moved by one per card while a card can summon several. two objects sharing a global id are one object to the client - getGameObjectIndex finds the first and reuses it - so the duplicates never became objects, never got models, and left the client and the server holding different sets, which no checksum can survive. |

scroll-server
A server for the scroll client (Clash Royale 2.0.1306, iOS). Takes a real
client from TCP connect to the lobby: login, own home data, chests, card
upgrades, the shop.
Requirements
- Rust 1.75+
- PostgreSQL 16
Running
createdb scroll
cargo run --release -p scroll-server
Listens on 0.0.0.0:9339, the port the client hardcodes. The schema is created
on first boot. DATABASE_URL defaults to postgres:///scroll.
On macOS a Homebrew cluster may need LC_ALL=C to start at all.
That runs everything in one process. For real isolation, SCROLL_MODE=supervised
makes it spawn the three services as child processes and restart any that dies,
with backoff:
SCROLL_MODE=supervised ./target/release/scroll-server
They can also be started by hand, in any order:
cargo run --release -p auth-service
cargo run --release -p game-service
cargo run --release -p gateway
Checking it without a phone
scroll-probe speaks the same protocol and prints the decoded lobby:
cargo run --release -p gateway --bin scroll-probe -- 127.0.0.1:9339
Flags: --claim-free-chest, --buy-chest <name>, --desync. Pass an account
and pass token to reconnect as an existing player:
scroll-probe 127.0.0.1:9339 0 1 <passtoken>.
Pointing a client at it
The client hardcodes game.clashroyaleapp.com. Patch that string in the binary
inside the ipa to your machine's address, keeping the 23 byte slot NUL padded so
nothing around it moves.

Shop
config/shop.json lists what the server sells, as Name#count:
{
"offers": [
{ "id": 1, "give": "Gold#1000" },
{ "id": 5, "give": "chest:Gold#1" },
{ "id": 7, "give": "Diamonds#500", "cost": "Gold#20000" }
]
}
Names resolve against the csv tables. cost is optional; without it the server
charges the same price the client computes from the game data.
