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

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
