Crazy Tractor's Infinite Level System
In Crazy Tractor, the wild, chaotic fun wouldn’t be possible without one of our most crucial behind-the-scenes systems: the Infinite Grid. This clever bit of tech makes sure our world feels massive and alive—without ever actually needing to be infinite.
At the heart of it is a looping tile system that follows the player around. Instead of endlessly generating new land, we shift existing tiles around the player based on their position. This approach keeps performance tight and visuals seamless, which is essential for a fast-paced, arcade-style game like Crazy Tractor.
This system does much more than just manage where the grass goes. It:
Handles veggie respawns and enemy placements dynamically through a custom tile updater.
Uses special spawn points that move with the outer rows to prevent "pop-in" when the camera zooms out.
Organises each cell into up to 10 individual graphic layers, giving us full control over how the world looks and feels.
From subtle things like skid marks and dirt trails, to chaotic effects like sheep explosions, every visual detail blends in thanks to this structure.
Integrates particles and environmental effects into specific layers so they visually sit inside the world, not just float on top of it.
This system is a core part of Crazy Tractor’s magic. Without it, the game would feel stitched together—lacking the charm and polish we’re proud of.
What You'll Learn
Over the next five lessons, we’ll break this system down step-by-step:
Grid Data Structures – How to set up and manage a reusable grid of tiles.
GameObject Positioning – Placing tiles and objects relative to the player.
Simulating Infinite Worlds – Moving and wrapping tiles around the player.
Efficient Tile Updating – Refreshing only the tiles that need it.
Grid Extensions – Custom spawns, layered graphics, and visual polish.
By the end, you’ll understand not only how to build your own looping world system—but how to shape it into something dynamic and beautiful, just like in Crazy Tractor.
Let’s get into it.
