In this Endless Runner UE5 tutorial, I build a complete in-game currency system where the player can collect coins and see the count update on the HUD. I start by grabbing a simple coin FBX, importing it into the project, and then I quickly tweak the material by pushing a bit of emissive so the coin looks brighter and pops in gameplay. After that, I create a clean “Base Currency” actor blueprint with a mesh, a sphere overlap for pickup detection, and a Rotating Movement Component so the coin spins automatically on the Z axis without extra manual tick logic. Then I wire the pickup into the GameMode using a Blueprint Interface function called Add Currency (integer value). The big win here is I don’t need a hard reference—on overlap I just verify it’s the player, call the interface on the GameMode, add the value, and destroy the coin. For spawning, I add a Spawn Coin event in the Flow BP, randomize lane (0–2) and length (5–10), and place coins in a continuous line with a fixed gap. Finally, I fix the “coins going through platforms” issue by doing a line trace to find the surface height and snapping the coin to spawn about 50 units above the hit point. I finish by duplicating UI elements in my Main HUD and updating the coin text every time a coin is collected (with minimum digits set to 2 for a clean 00-style display).
