[REQUIRED] A simple infinite level generator

I have a simple Minecraft- like game made by Filly-the-owl https://forums.unrealengine.com/showthread.php?108251-Free-Tiny-Blueprint-Minecraft-Clone-Source In it there is a level generator which makes a platform of cubes. I want to make this platform generate when the player reaches the end of the platform . I had put a torus at the player’s feet which when end overlap would set the level gen bool but it did not work. Any ideas how to make an infinite level generator/checker like Minecraft, Minetest ? Basic C++ also accepted. :smiley:
