Motorsport Showdown

I've been recently developing a mobile title using Unreal Engine. Motorsport Showdown is a genre-blending mobile game that combines endless runner gameplay, personnel management, and car customization, all wrapped in the thrill of motorsport.

 

I've developed the entire project solo, without using almost any third-party assets. I coded all gameplay in C++, rigged and animated every animation, modeled, textured, and built all assets and shaders, designed the UI, and even self-produced most of the game's audio.

The following video is a short demo of some of the progress I've made in my development. This is still Pre-Alpha content.

Project Breakdown

Seamless Interaction Systems Between Mechanics and Vehicles

As of recent, the project's architecture contains over 30 custom C++ classes. One unique class I'd like to highlight that's the backbone behind the seamless interaction systems around the vehicles inside the garages, is the VehicleDataAsset.

This class derives from the Data Asset class and contains properties you would expect such as a vehicles name, skeletal meshes, and an animation blueprint.

But I've also implemented a Task Sequence section which specifies the sequence of actions a mechanic must complete for a given task on a vehicle. I devised this to be part of the VehicleDataAsset since not all cars follow the same sequence of actions to complete the same task (i.e. Some Engines are under the hood while some lay under the trunk).

This section then works in conjunction with the Mechanic class to execute a wide variety of interactions between the Mechanic and a Vehicle allowing for the transfer in ownership of VehicleComponents and synced animations.

Class Requirements:

  • Editable within engine

  • Easily referenceable in other classes

  • Not an actor that is spawned into the world

  • Concise property list

Vehicles

Since a portion of the game revolves around repairing NPC cars as well as customizing player cars, I designed a custom VehicleRig which would allow for components to be attached to various sockets and allow for seamless animations when mechanics are tasked with removing them from the vehicle. While considered hero assets for this project I built the vehicle assets to be as performant as possible without sacrificing fidelity since the target platform will be mobile. The example below comprises of 45k tris.

Dynamic Character Customization

The project also contains mechanic randomization to offer a diverse set of characters for players to choose from to work in the garages. Customization include gender, race, hair and eye color, as well as randomization of currently 12 different outfits. The system also links the relative UI portrait to each 3D mechanic. All assets including 3D models and a UI characters were self produced.
