In Part 18 of my Unreal Engine 5.1 Endless Runner series, I add moving obstacles—specifically moving cars—so the level feels more alive and reactive. I’m using the free Vehicle Variety Pack from the Unreal Marketplace (the regular one, not the Volume pack), and I also show the workaround if you’re on UE 5.0/5.1/5.2 where the asset doesn’t show as compatible: enable “Show all projects” and add it using version 4.27. After importing, I pick a couple meshes (Sports Car and Hatchback), but the same setup works for any moving obstacle, not just vehicles. I create a child blueprint from BP_Obstacle (like BP_Car1), set up the mesh scale/rotation, and build two box collisions: a small one for the actual hit/death, and a larger trigger that starts the movement when the player overlaps it. For the movement, I use a Timeline and a simple Lerp on the X location, using an Arrow component as the target reference. When the Timeline finishes, I delay a bit and destroy the actor, and I also mention where a “Play Sound Attached” fits if you want vehicle audio. Finally, I hook spawning into BP_Floor with a “Spawn Cars / Spawn Moving Obstacles” function, using a Floor Count variable in the GameMode plus randomness to control frequency. As an optional extra, I also create stationary vehicle variants and spawn them as alternatives so the obstacle variety stays interesting.
