Setting Up Your Obby Generator Foundation
Creating an obby generator requires a solid understanding of scripting fundamentals and modular design principles. Start by establishing a main script that will handle the generation logic, typically placed in ServerScriptService for security and performance reasons.
Your generator needs three core components: a parts library containing pre-built obstacle sections, a spawning system that places these sections in sequence, and a cleanup mechanism to remove old sections and prevent memory issues.
Building Your Obstacle Library
Design individual obstacle modules as separate models in ReplicatedStorage or ServerStorage. Each module should be self-contained with consistent dimensions – typically 50×50 studs works well for most obby sections. Include various difficulty levels like basic jumps, moving platforms, spinning obstacles, and timed challenges.
Store these modules in a folder structure organized by difficulty or theme. This makes it easier to randomly select appropriate obstacles based on player progress or specific generation rules you want to implement.
Implementing the Generation Algorithm
Use a simple loop-based system that continuously spawns new sections ahead of the player. Track the player’s position and generate new obstacles when they reach certain checkpoints. A basic algorithm might look like checking if the player is within 100 studs of the last generated section, then spawning the next one.
Implement random selection from your obstacle library using math.random(), but consider weighting the selection based on difficulty progression. Early sections should favor easier obstacles, while later sections can include more challenging combinations.
Managing Performance and Cleanup
Set up automatic cleanup to remove obstacles that are far behind the player – usually anything more than 200-300 studs back. This prevents the game from becoming laggy as the obby extends infinitely.
Use efficient spawning techniques like cloning pre-made models rather than creating parts from scratch each time. Store references to spawned sections in a table so you can easily track and remove them when needed.
Adding Polish and Variation
Include checkpoint systems every 10-15 sections to prevent frustrating restarts. Add visual variety by randomizing colors, materials, or decorative elements even when using the same base obstacle designs.
Consider implementing difficulty scaling where obstacles become progressively more challenging, or add special mechanics like power-ups, speed boosts, or temporary invincibility to keep gameplay engaging throughout the infinite generation.

TL;DR
Build an obby generator using modular obstacle sections, spawning algorithms, and cleanup systems. Create a library of pre-made obstacles, implement random selection with difficulty scaling, and manage performance through automatic cleanup of distant sections.
