How to Develop an Endless Runner Game in Unreal Engine 

Here are the key steps to develop an endless runner game in Unreal Engine:

Laying the Foundation of Game’s Mechanics 

Establishing the foundation for game mechanics should be the priority, as it sets the stage for the entire game development. It involves determining the core gameplay loop, including the player’s character, which will run automatically, and the preliminary interaction, which involves jumping, sliding, or shifting sideways to circumvent obstacles. 

Fast-paced action and continuous gameplay are the key aspects that endless runner games captivate players with. Game developers make use of Unreal Engine’s Blueprint visual scripting system and C++ to create high-performance game mechanics. The process involves implementing obstacle interaction, character movement, and progressive difficulty scaling, ensuring an engaging, immersive, and seamless gaming experience.

Example: “Tron RUN/r”

“Tron RUN/r” is one of the examples of Endless Runner games developed with Unreal Engine 4. Here’s how the very game used Unreal Engine to be highly interactive and immersive:

• Employed Blueprints and created smooth and highly responsive character controls.
• Leveraged Unreal’s physics engine, ensuring smart handling of fast-paced dodging and obstacle interactions.
• Implemented real-time lighting and reflections and fitted the neon aesthetic of the Tron universe.
• Helped in performance optimizations to ensure smooth gameplay at high speeds.

Constructing the Game Universe 

Constructing a visually stunning and immersive game universe requires a detailed setting and background design that captivates players. The process begins by ascertaining the theme, whether it’s urban, futuristic, or fantastical, and then letting it navigate the narrative and visual elements. 

Game developers leverage Unreal Engine’s robust rendering engine, including features such as Nanite for detailed environment creation and Lumen for dynamic lighting. They use Quixel Megascans and custom 3D assets, allowing them to create a visually appealing and highly engaging game universe.  

Unreal Engine allows them to create immersive landscapes that evolve as the player progresses. Game developers can implement various atmospheric effects, such as weather changes and lighting, to enrich the game environment.

Example: “Supermoves”

Utilizing Unreal Engine 5, “Supermoves” creates a vibrant parkour-based universe, enabling players to perform different moves, including flipping and wall running in diverse environments. Here’s how Supermoves leveraged Unreal Engine’s competencies to stand out:

• Leveraged Lumen Global Illumination to create dynamic lighting capable of reacting realistically to movement.
• Utilized Nanite Virtualized Geometry, ensuring highly detailed cityscapes without affecting performance.
• Employed procedural tools to create varied environments that feel fresh every run.
• Ensured seamless integration of physics-based interactions like wall-running and flipping.

Creating the Game Environment 

Creating a well-crafted game environment requires enriched game art and experience. Game developers, in this phase, develop detailed environments, ensuring the game delivers an interactive and immersive gameplay experience. Using Unreal Engine’s Level Designer and procedural generation techniques, game developers create varied and dynamic environment settings. 

Furthermore, leveraging landscape tools and material shaders ensures high-performance, optimized levels capable of running smoothly across platforms.

Example: “Ghostrunner”

Ghostrunner, integrating fast-paced action with a compelling narrative, enhances the overall gameplay experience, showcasing Unreal Engine’s versatility. Here’s how the game used the power of Unreal Engine:

• Used PBR (Physically-Based Rendering) for realistic metallic surfaces in a cyberpunk world.
• Integrated real-time reflections and ray tracing to enhance immersion.
• Leveraged highly detailed 3D assets like efficient LOD (Level of Detail) management without performance loss. 
• Ensured seamless transitions between levels using streaming technologies.

Implementing the Player Character 

Implementing the player character in an Endless Runner game includes designing animations, physics, and controls. It ensures seamless transitions between actions, such as running, jumping, sliding, and dodging obstacles. Game developers configure intuitive controls and mechanics to create a responsive and enjoyable player experience. 

Leveraging the competencies of Unreal Engine’s Character Movement Component, they enable smooth running, jumping, sliding, and dodging mechanics. In terms of mobile games, game experts tend to implement touch controls and gestures, fostering a seamless experience across devices.

Example: “BPM: Bullets Per Minute”

It’s a roguelike rhythmic first-person shooter game developed by Awe Interactive. This game integrates a Valkyrie character and has its actions synchronized to a rhythm, showcasing Unreal Engine’s competencies to handle complex character mechanics. Here’s how the game made use of Unreal Engine: 

• Employed inverse kinematics (IK) and animation blending for fluid character movements.
• Ensured easy implementation of character customization and power-ups.
• Allowed motion-captured animations to make character movement way more realistic.
• Offered Blueprint scripting, minimizing coding complexity while tweaking mechanics.

Character Models and Animations

Character models and animations are crucial in Endless Runner game.
