Overview

This coding challenge aims to separate the deterministic battle simulation packed into a separate simulation library from the Unreal Engine simulation viewer, which can be used to replay the battle outcome using the simulation library.

Unreal Engine Project

The Unreal Engine project is split into 2 logical modules:

• ArenaSimulation - simulation implementation
• ArenaVisualization - simulation viewer

The simulation outcome can be viewed directly on the project default map or in the UE log under the LogSimulation category. Grid size, balls amount, attack radius/cooldown, and visualization tick time are hardcoded to not waste time on configuration that never be used by anyone. But they can still be changed by tweaking code constants.

Simulation Library Project

The RawSimulation directory contains a Visual Studio solution as a proof of concept for separated simulation development. It's a Windows console application with a simulation outcome logged to standard output.

Pre-Requisites

• Visual Studio 2022
• Unreal Engine 5.4.4

Known Issues

• Grid size value should be even due to the limitation of standard UE checkered grid rendering material usage
• Rarely balls can intersect with a grid due to some bug
