Hey guys, welcome back to part 3 of my Unreal Engine 5.1 Endless Runner series. In this video I focus on one of the most important systems for an endless runner: the floor tiles, and how to make them auto-generate forever while you play. I start by creating a new Actor blueprint called BP_Floor, then I set up the components properly (Cube, Arrow, and Box Collision — added separately, not parented). From there I dial in the transforms (like scaling the cube to 10, 10, 0.5 and pushing the Arrow to X=500) and set the Box Collision to overlap only with the Pawn, so it can trigger the next tile spawn at the right time. After that, I jump into BP_RunnerGameMode and build the core logic with functions like Add Floor and Extend Floor. I store the attach transform in a Floor Attach Point variable, keep spawned tiles in a Floor Tiles array, and use a loop on Begin Play to spawn an initial batch (I usually keep Number of Tiles between 10 and 20 — I picked 15). I also show how to create a quick floor material using the textures from the link, apply it to the cube, and rotate the tile 90 degrees on Z. Finally, I fix a weird slowdown bug by changing the Addition node value from 1 to 2 in Extend Floor, and you’ll see the floor generating smoothly as the character runs.
