Game Developer Made PUBG-Style Battle Royale In C++ From Scratch

Since April of this year, Game Developer Rishi Khanna has been building a battle royale game from scratch, writing over 40,000 lines of C++ code within the Unreal Engine ecosystem, and has gathered some materials to showcase the progress made so far and to share insights from this journey.

This Battle Royale Game project includes all the classic battle royale mechanics – joining lobbies, aircraft drops, loot pickups, moving to safe zones, and, ultimately, surviving to be the last squad standing. Taking on a large and complex project like this required Rishi Khanna to constantly focus on optimizing, decoupling, and rigorously testing each feature to ensure a robust final prototype with minimal issues and zero game-breaking bugs.

This project allowed the developer to gain a deep understanding of Unreal Engine's Replication System. With optimization as a top priority, he focused on minimizing data transmission across the network to reduce latency, ensuring smooth gameplay without compromising on quality. Additionally, Rishi Khanna implemented Lag Compensation techniques, such as Server-Side Rewind and Client-Side Prediction. The result is a fully functional game prototype with a complete game loop.

Here are the key features and mechanics of this game:

• Replicated Weapon Mechanics
• Inventory System
• Armour
• Hitbox-based Weighted Damage
• Grenade, Smoke Grenade
• Vaulting
• Solo, Duo, Trio, Squad
• Knock Player
• Revive Player
• Eliminate Enemy and Team
• Win/Lose Match
• Death Box
• Server Side Rewind
• Client Side Prediction
• Blue Zone, Safe Zone
• Randomly generated Zone and Flight Path
• Zone Damage and Effects
• Weighted Random based Loot Generation
• Jump from Aircraft
• Skydive, Falling
• Parachute, Glide
• MiniMap and FullMap Widgets
• Steam SDK
• Create, Join, Configure Sessions
