Greg hooks showcase
The gregFramework repo ships GregShowcaseMod at mods/GregShowcaseMod/. It demonstrates the public API only:
GregEventDispatcher.On/Once/OnCancelable/UnregisterAllGregHookName.Create(GregDomain.*, "Action")GregPayload.Get<T>/GregPayload.Dumpfor anonymous payloads
Canonical hook strings
Runtime names look like greg.<DOMAIN>.<Action>. Always build them with GregHookName.Create — do not concatenate raw strings in mods.
Registry
greg_hooks.json at the gregFramework repository root is the canonical catalog (description, payloadSchema, strategy, optional legacy). A copy is emitted next to FrikaModdingFramework.dll for GregCompatBridge legacy resolution.
Authoritative documentation: greg hooks registry (IL2CPP) — regeneration script, whitelist, and Harmony deduplication rules.
FFI bridge and greg.* emission
DataCenterModLoader.EventDispatcher emits greg.* events through GregHookIntegration for the same gameplay moments as the Rust FFI event ids (money, cables, customers, save/load, etc.), even when the FFI bridge is not connected.
Payload access patterns
Pattern A — dynamic (anonymous types from compiler):
private static void OnCoinChanged(object payload)
{
dynamic p = payload;
float delta = (float)p.coinChangeAmount;
float balance = (float)p.newBalance;
MelonLogger.Msg($"Δ={delta} → {balance}");
}
Pattern B — GregPayload (reflection, case-insensitive property names):
private static void OnReputationChanged(object payload)
{
var amount = GregPayload.Get<float>(payload, "amount");
var rep = GregPayload.Get<float>(payload, "reputation");
MelonLogger.Msg($"Reputation: {amount} → {rep}");
}
Pattern C — typed record (when you define a shared contract in your mod or core):
// public record PlayerMoneyPayload(float CoinChangeAmount, float NewBalance, bool WithoutSound, bool Accepted);
// if (payload is PlayerMoneyPayload p) { ... }
Use GregPayload.Dump(payload) for one-line debug strings.
Prefix hooks and cancellation
Hooks that run before the original method (Harmony Prefix) can call GregEventDispatcher.InvokeCancelable(hookName, payload). Mods register GregEventDispatcher.OnCancelable(hookName, p => bool, modId); if any handler returns false, the integration can skip the original (e.g. Player.UpdateCoin). Der Showcase nutzt GregNativeEventHooks.PlayerCoinChanged (greg.PLAYER.CoinChanged).
Showcase: enable blockNegativeTransactions in content/modconfig.json to register a veto on large negative coinChangeAmount values.
Configuration
Edit content/modconfig.json next to the built DLL (defaults are copied from the repo). Keys include logPlayerEvents, logNetworkEvents, blockNegativeTransactions, reputationWarningThreshold.
