Structural Physics

structural-physics

Structural validation and damage systems for Three.js building games. Use when implementing building stability (Fortnite/Rust/Valheim style), damage propagation, cascading collapse, or realistic physics simulation. Supports arcade, heuristic, and realistic physics modes.

Structural Physics

Stability validation and damage systems for building mechanics.

Quick Start

import { HeuristicValidator } from './​scripts/​heuristic-validator.js';
import { DamageSystem } from './​scripts/​damage-propagation.js';

// Rust/​Valheim style stability
const validator = new HeuristicValidator({ mode: 'heuristic' });
validator.addPiece(piece);
const result = validator.validatePlacement(newPiece);
// result: { valid: true, stability: 0.85, supports: [...] }

// Damage and collapse
const damage = new DamageSystem(validator);
damage.applyDamage(piece, 50, 'physical');
damage.applyExplosiveDamage(position, 100, 10); // radius damage

Reference

See references/​structural-physics-advanced.md for:

  • Physics mode comparison (arcade vs heuristic vs realistic)
  • Material properties and decay rates
  • Damage state thresholds
  • Cascade mechanics

Scripts

  • scripts/​heuristic-validator.js - Fast validation (Fortnite/​Rust/​Valheim modes)
  • scripts/​stability-optimizer.js - Caching and batch updates for large structures
  • scripts/​damage-propagation.js - Damage states, fire spread, cascading collapse
  • scripts/​physics-engine-lite.js - Optional realistic stress/​strain simulation

Physics Modes

  • Arcade (Fortnite): Connectivity only, instant collapse, best for combat
  • Heuristic (Rust/​Valheim): Stability %, predictable rules, best for survival
  • Realistic: Full stress/​strain, computationally expensive, best for engineering sims
