Networking (Native)

Native worlds do not use the web multiplayer stack. They use Unreal's own networking — dedicated servers, actor replication, RPCs — and HELIX adds thin wrappers that make identity, tickets, and authoritative value checks ergonomic inside that model.

What HELIX wraps

• Instance tickets → connection. Players arrive with a platform-issued Instance Ticket; the HELIX wrapper verifies it during Unreal's login/connection handshake so only authorized players join.
• Identity on the server. Replicated player state is tied to the HELIX Player identity, not a raw connection — so Helix.* calls on the server know who they're for.
• Authoritative value checks. Helpers to keep wallet/inventory/ownership decisions on the server, mirroring the item execution tiers.

The model

Use Unreal replication as you normally would:

• Server is authoritative; clients send input/RPCs.
• Movement and cosmetic state replicate via Unreal's replication graph.
• Value-bearing actions (grant item, charge LIX, award reward) go through the server-side Platform API, never a client RPC you trust blindly.

// server-side authoritative grant, same Platform API as web
void AArenaGameMode::AwardWin(const FHelixPlayer& Player)
{
    UHelix::Get()->Inventory()->ConsumeAndGrant(/* atomic, idempotent */);
}

Scale

Native dedicated servers scale through Unreal's standard tooling and HELIX's hosting. Large-map, high-population worlds are a primary reason to choose Native over Web.
