Version Parity & Physics History

Patch History & Physics Engine Timeline

Track major Box2D physics calibrations, WebGL / HTML5 engine modernization milestones, and character balance adjustments from 2010 through 2026.

v1.95

HTML5 WebGL Physics Modernization & 60 FPS Sub-Stepping

2026-03-12

Optimized the modern WebAssembly/WebGL physics pipeline with enhanced 60 FPS sub-stepping precision, eliminating quantum collision tunneling through high-speed thin walls.

Key Physics & Engine Adjustments:
Box2D Continuous Collision Detectionphysics fix

Implemented Continuous Collision Detection (CCD) for all projectile harpoons and thin high-velocity wheel axles, stopping riders clipping through solid floors.

Wheelchair Guy Rocket Stabilizationbuff

Increased thruster vector angle damping by 12%, allowing easier rotational micro-adjustments during long horizontal glides.

Finish Line Trigger Hitboxphysics fix

Fixed an edge-case where decapitated heads moving above 40 m/s would occasionally fail to register victory on thin finish flags.

v1.90

Flash Deprecation & Total Jerkface WebGL Engine Migration

2020-12-28

Complete architectural migration from Adobe Flash to standalone modern JavaScript / WebGL / Canvas by Jim Bonacci, preserving 100% of classic Box2D physics parity.

Key Physics & Engine Adjustments:
Core Engine Pipelineengine port

Re-engineered the entire client runtime in native JavaScript / HTML5 Canvas with custom Box2D integration, guaranteeing perpetual browser playability.

Ragdoll Blood Decal Persistencebuff

Increased maximum on-screen blood particle count by 300% without framerate degradation due to GPU hardware acceleration.

Pogostick Guy Spring Recoilphysics fix

Calibrated spring compression constants to match original ActionScript 3.0 frame rate timing precisely.

v1.82

Helicopter Guy Rotor Dynamics & Hitbox Optimization

2016-08-15

Refined the aerodynamic lift curves and rotor collision geometry for Helicopter Guy, alongside mobile cross-play compatibility updates.

Key Physics & Engine Adjustments:
Helicopter Guy Rotor Blade Durabilitynerf

Rotor blades now break under 1,800 N of shear force instead of 2,400 N when striking concrete ceiling blocks.

Moped Couple Nitrous Boost Durationbuff

Extended continuous nitrous burn time from 3.0 seconds to 3.8 seconds before pressure depletion.

v1.75

Lawnmower Guy & Multi-Limb Shredder Update

2014-04-10

Introduced Lawnmower Guy featuring dynamic rotating underbody blades capable of slicing organic matter and minor debris into physical gibs.

Key Physics & Engine Adjustments:
Lawnmower Guy Cutting Deckbuff

Added high-speed rotating blade fixture with kinetic ragdoll severance triggers.

Irresponsible Mom Articulated Trailer Jointphysics fix

Strengthened the distance joint tether between bicycle frame and baby carrier to avoid spontaneous snapping on minor bumps.

v1.50

Effective Shopper & Explorer Guy Minecart Expansion

2012-09-02

Added heavy mobility vehicles expanding tactical playstyles with massive kinetic momentum and rail-riding adherence.

Key Physics & Engine Adjustments:
Effective Shopper Basketbuff

Grocery items inside the wire basket now possess dynamic physical collision masks that absorb forward projectile damage.

Explorer Guy Minecart Magnetic Clampbuff

Implemented magnetic wheel flange adherence allowing inverted loop-de-loops without falling from rails.

v1.00

Happy Wheels Flash Launch by Jim Bonacci

2010-06-04

The initial public release of Happy Wheels on TotalJerkface.com, introducing Wheelchair Guy, Segway Guy, and the revolutionary user level editor.

Key Physics & Engine Adjustments:
Initial Releaseengine port

Launched with Box2D ragdoll dismemberment physics, community level sharing, and 4 original playable characters.
