Cause: Client-side prediction cache not clearing.
Fix: Update to v1.3.4 which includes OnDespawned RPC callback fix. Alternatively, manually call NetworkServer.Destroy(gameObject, 0.5f).
Version 1.3.4 | Unity Engine | Multiplayer (STP/Loopback)
In the crowded ecosystem of Unity assets, finding a robust, production-ready template for multiplayer survival games remains a daunting challenge. Enter the Multiplayer STP Survival Template PRO v1.3.4 — a comprehensive framework designed to leapfrog months of boilerplate networking code and focus directly on what makes survival games tick: resource management, environmental threats, and social interaction.

This article provides an exhaustive technical and design overview of version 1.3.4, analyzing its core architecture, new features, and practical implementation strategies.
The Multiplayer STP Survival Template PRO is a comprehensive starting framework designed for developers building online survival games. This template provides a ready-to-play foundation, handling the complex backend logic required for multiplayer survival mechanics so developers can focus on content creation and game design.

The terrain is divided into 256x256 meter chunks. v1.3.4 introduces:
| Problem | Solution |
|---------|----------|
| Player not spawning | Check NetworkManager → Player Prefab and Spawn Info |
| Items not syncing | Ensure prefab is in Registered Spawnable Prefabs |
| Building ghost flickers | Adjust NetworkTransform.sendInterval to 0.05 |
| AI doesn’t move | Bake NavMesh in scene (Window → AI → NavMesh) |
| Host sees double HUD | Disable local player HUD for host client (template has check) | Version 1
The "STP" in the asset name refers to State Transfer Protocol (or, in some contexts, Sequential Tick Propagation). Unlike traditional authoritative server models (like Mirror or Photon) that rely on frequent RPCs (Remote Procedure Calls), STP optimizes bandwidth by batching state changes into compressed delta snapshots.
Key STP Characteristics in v1.3.4:
For survival games, where hundreds of resources (trees, rocks, animals) exist on a map, STP reduces bandwidth usage by approximately 60-70% compared to traditional UNET or raw Socket solutions.
