    [RELEASED] FGear Vehicle Physics (v1.0)

    hi,

    FGear is a custom vehicle physics solution that helps you build arcade or semi-arcade style racing games. It is mostly focused on 4 wheel cars but multi axle setups are also possible. The library consists of a core module and some extra components that were used while making the demos/example project.


    MarketPlace : Available Here


    Available Demos :
    *Controls for Pc Demos: Arrow keys + Space for handbrake + R for reset

    Disclaimer: The red sports car model in the track/sandbox demo is not included in the package or the example project.




    Here is the core feature list:

    Core features:
    • Desktop or mobile.
    • Adjustable integration steps.
    • Simplified pacejka, pacejka96 and MF6.1 tire model options.
    • 3D wheel support(multiple raycasts).
    • Simple engine model with a torque curve.
    • Configurable auto/sequential/manual(h-pattern) transmissions.
    • Open, locked or limited slip differentials.
    • Ackerman steering, toe and camber.
    • Adjustable torque and brake distribution of axles.
    • Simple spring/damper suspensions with preload option.
    • Multi axle setup support.
    • AeroDynamics component for drag and downforce effects.
    • Standard input manager with keyboard,joystick and wheel+shifter support.
    • Driving aids like abs, asr, esp and anti roll bars.
    • Detailed telemetry ui.
    • Various sample setups and demos.
    In addition to the core features we will prepare a couple sample scenes and for these there will be some extra features available like:

    Extras:
    • Adjustable 3rd person camera.
    • Sample visual&sound effects like engine, skid and muzzle effects.
    • Mobile input demo.
    • Custom collider component for separating collision from inertia.

    For more information you can visit https://fgearvp.wordpress.com

    TODO for next release
    • Bug fixes
    • Network replication
    • Runtime modification demo
    • Benchmark map

    KNOWN ISSUES
    • The unit of suspension preload is wrong in documentation(it says percentage but it is in meters)
    • Preload calculation has a bug that reduces ride height as preload increases
    • Highly damped suspensions may not behave correctly
    • Gear change speeds are not recalculated when you change gear ratios in runtime

    Any feedback is welcome.

        unfortunately the included cars will not be game ready models, basic models like unreal's sample vehicles.
        the car models in the touring demo are not included.

          But will this get updates or then be abandoned like other similar ones already on the marketplace and not mantained anymore?

            FGear 1.0 was released for unity in January and we released two more updates until now, it will be similar for the unreal version. If we do not hit some technical limitation/problem wall, we will add all the features listed in the first post. In the long run we will continue improving the core library, fixing bugs etc. but we do not want to spend time on gameplay specific features like enter/exit vehicle or headlights etc. so the feature list may not expand a lot but we will try to keep the core features solid and stable.

              first screen, the core physics port is nearly complete but we still have much work to do.

                Can it be used without the need for c++?

                  it will be a plugin so you can both use c++ or blueprint.

                        hi, fgear supports multi axle setups but tracked vehicles have different mechanics so the initial version will not support that.
                        we continuously improve the library so we will consider adding this feature in the future releases.

                          i'm super interested into this one, i've been waiting for a long time for a proper car physics in ue4.

                          Subbed on YT & this thread so i wont miss a thing.

                          Don't forget to make it replicated for multiplayer games.

                            the initial release will not be replicated(it does not mean that you can not make a multiplayer game), this is planned for the first update after initial release.
