I'm building a mobile welding simulation game called "Arc & Spark: Welder's Journey" in Unity. CORE FEATURES NEEDED: - Realistic welding arc physics and visual effects - Touch/mouse controls for torch positioning and angle - Weld bead generation that responds to player technique - Heat simulation affecting metal appearance - Pass/fail evaluation based on weld quality metrics TECHNICAL REQUIREMENTS: - Support for iOS and Android - Optimized for mobile performance - Modular code architecture for adding new welding processes (SMAW, MIG, TIG) - Save/load system for player progression - In-app purchase integration ready Please provide: 1. Recommended Unity project structure with folders/namespaces 2. Core class architecture (managers, controllers, data models) 3. Initial setup instructions for a new Unity project 4. Recommended Unity packages/assets for particle effects and physics Do not write full implementation yet - just architecture and setup.

Now let's implement the core welding simulation mechanics for Unity. WELDING BEHAVIOR TO SIMULATE: - Arc length affects heat input (closer = hotter) - Travel speed affects bead width (slower = wider) - Torch angle affects penetration and bead shape - Heat accumulation causes metal to glow (black → red → orange → white) - Puddle formation and solidification behind torch - Defects: undercut (too fast), excessive buildup (too slow), porosity (bad technique) CONTROLS: - Touch/drag to move torch position (X, Y coordinates) - Tilt device or second finger to control torch angle - Trigger button (screen button) to maintain arc EVALUATION METRICS: - Bead width consistency (measure variance) - Travel speed consistency - Arc length consistency - Penetration depth (simulated based on heat/time) - Visual defects detected Please provide: 1. WeldingPhysicsController.cs - handles real-time welding calculations 2. WeldBeadGenerator.cs - creates visual weld bead as player works 3. HeatSimulation.cs - manages temperature zones and visual effects 4. WeldEvaluator.cs - grades weld quality after completion Include detailed comments explaining the welding science behind each calculation.

I'll implement the core welding simulation mechanics with detailed welding science explanations. Let me start by creating the required classes:
