LogicBattle::isEndConditionMatched, transcribed: the battle is over when end_counter is positive, when either king is dead, when tick/20 seconds reach MatchLength + OvertimeSeconds, or - once past MatchLength - when the crowns differ. the divisor is the 0x66666667/2^35 multiply in the client, which is a divide by twenty, so the battle runs at 20 ticks a second. crowns come from LogicSummoner::getStars: three when the enemy king is down, otherwise two minus the enemy princess towers still standing, which is exactly what leader_towers holds. BattleRegistry keeps the LogicGameMode we built for each account and advances it on the tick the client reports in its turn message, so the server now tracks the clock, the crowns and whether the battle is over, and drops the session when the player goes home. the two isSummoner guards in the overtime branch are left out: they only fire for an object that is not a summoner, which a king tower always is. |

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.
