Survival Game Framework is a complete, production-ready C++ plugin that provides all core systems needed to build a survival game. Data-driven architecture - just fill in DataTables with your items, recipes, and buildings. No C++ coding required!

📖 Documentation and HOW TO | 💬 Discord Support |

🏗️ Hybrid Building System (v1.1.0)

• HISM-based placement for static buildings — supports 50,000+ elements vs ~2,000 with Actors

• ~90% draw call reduction and ~80% memory savings for large bases

• Automatic routing: static pieces (walls, floors, foundations) use HISM, interactive (doors, storage, stations) spawn as Actors

• Full network replication via Multicast RPCs using deterministic IDs (FName + int32, not component pointers)

• Save/Load support for all building instances (compact format: Transform + BuildingID + Health)

• Nanite-ready — automatic support when meshes have Nanite enabled

🌲 Foliage Harvesting System (v1.2.0)

• Harvest trees, rocks, bushes painted with UE5 Foliage Tool — no Actor conversion needed

• Per-instance health tracking with lazy allocation (zero overhead for untouched foliage)

• Mesh Mapping: connect any foliage mesh to a ResourceID from your DataTable (multiple variants → same resource)

• Auto-discovery of all ISM/HISM/FoliageISM components at BeginPlay

• Tool requirement validation (Axe for trees, Pickaxe for rocks, etc.) with bonus drops

• Scale-to-zero hiding with configurable respawn timers

• Network-safe Multicasts using ResourceID + InstanceIndex for reliable cross-client sync

• Save/Load: only damaged/depleted instances stored (minimal save data)

🎒 Inventory System

• Configurable inventory size and hotbar slots

• Item stacking with customizable max stack sizes

• Weight system with encumbrance effects

• Full multiplayer replication

• Blueprint events for easy UI integration

🔨 Crafting System

• Multi-ingredient recipes defined in DataTables

• Crafting station requirements (Workbench, Forge, etc.)

• Timed crafting with progress events

• Recipe unlocking and progression

• Automatic ingredient validation

🏠 Building System

• Grid-based placement with configurable grid size

• Snap points for connecting building pieces

• Preview ghost with valid/invalid visualization

• Building categories: Foundations, Walls, Roofs, Furniture
