Gameplay Over Simulation
Physics in arcade games serves gameplay, not scientific accuracy. We believe the best physics implementations are those that feel right to players, even when they deviate from real-world behavior.
This principle guides every decision we make. When realistic physics creates frustration, we adjust. When simplified physics serves the game better, we simplify. The player's experience always takes priority.
Performance as a Feature
Smooth, consistent frame rates aren't just technical requirements—they're essential to good game feel. Players can perceive frame time variations that disrupt their sense of control and timing.
We treat performance optimization as integral to physics design rather than an afterthought. Systems are built efficient from the start, ensuring impressive visuals never compromise responsiveness.
Predictability Builds Mastery
Players need to understand cause and effect in physics systems. When interactions behave consistently, players can develop skills and strategies. Random or chaotic behavior frustrates skill development.
Our implementations prioritize deterministic results where possible and ensure physics behavior follows logical rules players can learn, even if unconsciously.
Maintainable Solutions
Physics systems need to evolve with games. We build implementations that development teams can understand, modify, and extend without specialized knowledge.
Clear documentation, sensible code organization, and understandable parameters ensure physics doesn't become a black box that only external specialists can touch.
Why This Methodology Works
These principles emerged from years of solving real physics challenges in arcade game development. Each reflects lessons learned from projects where pure simulation approaches failed to serve gameplay needs.
By focusing on the player experience rather than physical accuracy, we create systems that accomplish what matters most—making games more enjoyable to play. The technical sophistication exists to serve this goal, not for its own sake.
Our Implementation Framework
Every project follows a structured approach that ensures thorough understanding, careful implementation, and sustainable results. Each phase builds on previous work while remaining adaptable to project-specific needs.
Discovery & Analysis
We begin by thoroughly understanding your game's requirements and constraints. What platforms need to be supported? What gameplay experiences are most important? Where are current physics implementations falling short?
This phase involves playing the game, reviewing technical documentation, and discussing priorities with the development team. We identify specific challenges and opportunities that physics work can address.
System Design
Based on discovery findings, we design physics systems tailored to your specific needs. This includes selecting appropriate algorithms, planning performance budgets, and defining parameter structures.
Design decisions balance technical requirements with practical constraints. We consider maintainability, scalability, and how systems will integrate with existing code. Detailed specifications ensure alignment before implementation begins.
Core Implementation
Physics systems are built according to design specifications, with regular check-ins to demonstrate progress and gather feedback. We work collaboratively with your team, explaining our approach and answering questions.
Implementation prioritizes getting core functionality working correctly before adding complexity. This approach allows early testing and ensures a solid foundation for advanced features.
Parameter Tuning
With systems functional, we focus on making physics feel right. This iterative process involves adjusting parameters, testing gameplay, and refining behavior based on feedback.
Tuning continues until physics interactions meet quality standards and serve gameplay goals. We document the reasoning behind parameter choices to guide future adjustments.
Performance Optimization
Once behavior meets expectations, we optimize for performance. Profiling identifies bottlenecks, and targeted improvements ensure smooth operation across all target platforms.
Optimization maintains physics quality while improving efficiency. We verify that optimizations don't introduce new issues or change gameplay feel in unwanted ways.
Documentation & Transfer
Comprehensive documentation explains how systems work, what parameters control, and how to extend functionality. We provide examples demonstrating common modifications.
Knowledge transfer sessions ensure your team can maintain and evolve physics systems independently. We share the reasoning behind design decisions and highlight potential pitfalls to avoid.
Grounded in Proven Principles
While our approach prioritizes gameplay over simulation, it's built on solid understanding of physics and computer science fundamentals. We apply established algorithms and best practices adapted for game development contexts.
Physics Fundamentals
Our team understands Newtonian mechanics, rigid body dynamics, and collision response theory. This knowledge informs our implementations even when we deliberately deviate from pure simulation.
Knowing the rules helps us break them appropriately for gameplay purposes while avoiding physically implausible behavior that breaks immersion.
Computational Methods
We use established numerical integration methods, spatial partitioning algorithms, and optimization techniques from computer graphics and physics simulation research.
These proven approaches provide reliable foundations that we customize for specific arcade game requirements and performance constraints.
Game Development Standards
Our implementations follow industry best practices for game code architecture, performance profiling, and cross-platform development.
We stay current with evolving standards and techniques, incorporating lessons from the broader game development community into our methodology.
Quality Assurance & Testing
Every implementation undergoes thorough testing to verify correctness and performance. We use automated tests to catch regressions and ensure behavior remains consistent across code changes.
Platform-specific testing validates that physics works correctly on all target hardware. Performance profiling identifies any bottlenecks before they become problems in production.
This rigorous approach to quality ensures implementations are reliable and maintainable, reducing the likelihood of physics-related bugs reaching players.
Common Physics Implementation Challenges
Many arcade game projects encounter similar obstacles when implementing physics. Understanding these common challenges helps explain why specialized expertise makes a difference.
Off-the-Shelf Physics Engines
General-purpose physics engines prioritize simulation accuracy, which often conflicts with arcade gameplay needs. Their default behaviors may feel too realistic—objects take too long to settle, collisions respond too softly, or interactions lack the snappy feel arcade games require.
While these engines can be configured for better arcade feel, doing so requires deep understanding of their internals. Teams often struggle with inadequate documentation and parameter spaces that weren't designed for arcade use cases.
Simplified Custom Solutions
Teams building their own basic physics from scratch often underestimate the complexity involved. What starts as simple collision detection becomes a maintenance burden as edge cases accumulate and bugs prove difficult to fix.
Without physics expertise, custom implementations may use inefficient algorithms or miss important details like proper collision response. The result is physics that feels off or performs poorly, requiring extensive iteration to improve.
Performance Bottlenecks
Physics calculations can easily become performance bottlenecks if not carefully optimized. Naive collision detection algorithms scale poorly with object count. Particle systems can overwhelm processors if not designed with performance in mind from the start.
By the time performance problems become apparent, significant code may be built on inefficient foundations. Fixing these issues often requires substantial refactoring that delays project timelines.
Lack of Tuning Knowledge
Even when physics systems work correctly from a technical standpoint, they may not feel right during gameplay. Tuning physics for good game feel requires understanding how different parameters interact and affect player perception.
Without this expertise, teams spend excessive time in trial-and-error iteration. Parameters are adjusted without clear understanding of their effects, leading to improvements in one area that create problems elsewhere.
Our Solution to These Challenges
Physics Lab exists specifically to address these common implementation obstacles. We bring specialized knowledge that helps projects avoid typical pitfalls and reach quality physics faster. Our methodology evolved from encountering and solving these exact challenges across numerous projects.
What Makes Our Approach Unique
Arcade-Specific Focus
Unlike general physics solutions, our methodology specifically targets arcade game requirements. We understand that arcade physics needs to be responsive, predictable, and satisfying rather than perfectly accurate.
This specialized focus means we already know which shortcuts work well for arcade contexts and which aspects require precision. Projects benefit from this accumulated knowledge rather than rediscovering it through trial and error.
Practical Performance Engineering
We design physics systems with performance budgets from the outset. Rather than implementing features and hoping they'll run fast enough, we consider efficiency at every design stage.
Our approach balances visual impressiveness with technical constraints. We know how to allocate processing power to maximize perceived quality while maintaining smooth frame rates across target hardware.
Parameter-Driven Design
Our implementations expose meaningful parameters that let developers adjust behavior without modifying code. These aren't just raw physics constants—they're intuitive controls that map to game design concerns.
Well-designed parameters accelerate iteration and empower game designers to tune physics feel themselves. Documentation explains what each parameter affects in gameplay terms, not just technical ones.
Knowledge Transfer Priority
We view our role as building capability within client teams, not creating dependency on external experts. Every implementation includes thorough documentation and explanation of our reasoning.
By the time projects conclude, development teams understand their physics systems well enough to maintain and extend them independently. This approach provides better long-term value than delivering opaque solutions.

Realistic Expectations
Success in physics implementation isn't about achieving perfect numbers across all metrics. Different projects have different priorities, and some trade-offs are necessary.
For example, a game targeting mobile platforms might prioritize performance efficiency over maximum visual complexity. A competitive fighting game might emphasize deterministic behavior over natural-looking secondary motion.
We work with teams to establish appropriate success criteria based on their specific context, then track progress toward those goals throughout implementation. This ensures effort focuses on improvements that matter most to each project.
