Harvesting System
Universal Foliage Detection
Proximity-based detection for HISM, ISM, SMC, and PCG foliage. Automatically swaps mesh instances to harvestable actors on approach.
Universal Damage Pipeline
Works with native UE damage (
ApplyDamage, ApplyPointDamage, ApplyRadialDamage), GAS Gameplay Effect Executions, or fully custom damage systems via direct notification.Multi-Stage Harvesting
Configurable harvest stages with loot table rolls at each stage, remnant/stump placement after depletion, and per-node respawn timing.
Loot Tables (No Item Dependency)
The plugin rolls loot and fires events with a payload array — it never handles items directly. Integrate with any inventory system via Blueprint events or delegate binding.
Save / Load
Full harvested node state persistence via
UHarvestSaveSubsystem. Save slot management, async save/load, and node restoration with configurable counts.Biome System
Procedural Biome Spawning
Place
ABiomeVolumeActor, assign a UBiomeDefinition data asset, press Play. Instances spawn procedurally based on density, slope, and noise rules — immediately harvestable.Exclusion Volumes
Block biome spawning in specific areas — roads, buildings, water, and hand-placed trees. Supports Box or Sphere shapes with per-biome or global exclusion.
Seasonal Biomes
Season mask per biome definition (Spring/Summer/Autumn/Winter). Call
SetSeason() on UBiomeSeasonManager to trigger automatic biome clear and respawn with transition effects.Ambient VFX & Audio
Per-biome Niagara VFX, looping audio, and Wind Material Parameter Collection integration for fully atmospheric biome environments.
Damage Pipeline Modes
| Mode | Use When |
|---|---|
| NativeAllDamage | Standard UE projects using any of the ApplyDamage variants |
| NativeAnyDamage | Projects using only UGameplayStatics::ApplyDamage |
| GAS | Call NotifyGASDamage() from your Gameplay Effect Execution class |
| Custom | Call NotifyHarvestDamageEvent() directly from any custom system |
| None | Scripted depletion only via ForceHarvest() — no automatic pipeline |
Core Classes & API Reference
| Class / Asset | Purpose |
|---|---|
| AWCHarvestableActor | Base harvestable actor. Swap target — HISM/ISM/SMC/PCG instances become this on player approach. Handles stage progression, loot rolls, and depletion. |
| UHarvestSaveSubsystem | World subsystem for harvest state persistence. Async save/load per slot. Restores depleted and staged node states on load. |
| UHarvestDetectionComponent | Lives on the player pawn. Proximity detection, swap triggering, range configuration. |
| UHarvestNodeDefinition | Data asset per foliage type. Health, stages, loot table reference, remnant mesh, respawn time, VFX/audio per stage. |
| ABiomeVolumeActor | Place in level, assign a UBiomeDefinition. Procedurally spawns harvestable foliage instances at runtime based on density and slope rules. |
| UBiomeDefinition | Data asset: node types, density, slope range, season mask, exclusion layer, Niagara VFX, looping audio, wind MPC. |
| UBiomeSeasonManager | World subsystem. Call SetSeason() to trigger biome clear and seasonal respawn with transition effects. |
| ABiomeExclusionVolume | Block biome spawning within a Box or Sphere volume. Supports per-biome or global exclusion. |
