Short Description:

Lightweight UDP send/receive for Blueprints and C++ with string helpers, socket error events and live byte counters.

Long Description:

QuickUDP makes datagram networking effortless. One component handles sending and receiving UDP packets with game-thread Blueprint events, so you can talk to game servers, IoT devices or local tools without touching sockets.

Drop the QuickUDP component on any actor, open a send or receive socket with one call, and bind OnReceivedBytes or OnReceivedString. Datagrams arrive on the game thread ready to use, socket errors surface as Blueprint events instead of silent failures, and live byte counters make throughput visible while you tune. String helpers cover the common text-protocol cases so you never manually convert buffers.

UDP is the right tool for high-rate, loss-tolerant traffic: position beacons and telemetry, LAN discovery pings, OSC-style creative-tool control, lightweight sensor and IoT feeds, or quick device-to-editor debugging channels. QuickUDP keeps all of that a few nodes away from any Blueprint.

QuickUDP is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- Send and receive UDP from Blueprints or C++

- String send/receive helpers alongside raw bytes

- Socket error events and live byte counters

- IsSendOpen/IsReceiveOpen state queries

- Hex, Base64 and endpoint-parsing utility nodes

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
