In Part 9 of my Unreal Engine 5 endless runner series, I build an advanced spawning system where obstacles and platforms spawn pattern-wise instead of being totally random in the lanes. I start by fixing a small but important visual issue: at the beginning the player can see the start of the road, so I just shift the road a bit backward to hide that seam and make the run feel cleaner. After that, I set up a proper data-driven workflow using an Enum and a Struct. I create an “Objects to Spawn” enum (Obstacle, Platform, None), then a “Lane Spawn Struct” with Lane 1/2/3 values. In the GameMode, I store an array of these structs as my spawn patterns, so I can define combos like obstacle+platform+empty, single obstacle, single platform, mixed patterns, or even all lanes empty. In Blueprints, I pick a random pattern index, break the struct, shuffle the lane values so nothing is permanently bound to a specific lane, then loop through each lane and use a switch on enum to spawn the correct object (or nothing). Finally, I also mention keeping platform collisions simple (like using a basic box) so the game runs smoothly.
