Question 1

How do I integrate librg with ENet?

Accepted Answer

Check the example-enet.c file in the code/apps folder, which shows how to set up buffer handling and event callbacks. You'll need to manage ENet connections and pass data buffers to librg for entity synchronization.

Question 2

librg vs Photon: which is better for indie games?

Accepted Answer

librg is a lightweight middleware for C/C++ giving full control over networking and serialization, while Photon is a managed service with higher-level features but less flexibility. Choose librg for custom engines; Photon for rapid prototyping in engines like Unity.

Question 3

Can librg handle large-scale MMOs?

Accepted Answer

Yes, its area-of-interest management and chunk-based querying optimize bandwidth for many entities, but you'll need to implement scaling features like sharding or load balancing yourself, as librg focuses only on entity visibility.

Question 4

What's the best serialization library to use with librg?

Accepted Answer

The README suggests protobuf, flatbuffers, or msgpack—choose based on performance needs. For example, flatbuffers is great for zero-copy deserialization, but you must handle integration and data schema management independently.

Question 5

How does librg deal with network lag or prediction?

Accepted Answer

librg doesn't include lag compensation or client-side prediction; it's solely for entity synchronization. You'll need to implement these game logic aspects separately, which adds complexity for fast-paced games.

Question 6

Is there a C++ wrapper or binding for librg?

Accepted Answer

No, librg is written in pure C99, so you can use it directly in C++ projects, but there are no official high-level wrappers. You'll need to manage C-style APIs and potential manual memory management.
