Hello guys, welcome back to Part 12 of my Unreal Engine 5.1 Endless Runner tutorial series. In this video, I focus on adding proper mobile touch inputs so your runner controls feel right on phones, not just on keyboard. I start by creating a new Input Action called "Touch_IA" inside the Inputs folder, then I map it inside "IMC_RunnerDefault" using the "Touch1" key binding. After that, everything happens inside "BP_RunnerCharacter" where I set up the logic to track when touch is started, triggered, and completed. The main idea is simple: I store the touch start and touch end positions as Vector2D variables, then I calculate the swipe distance and direction. I use a threshold (length > 100) so tiny finger movement doesn’t accidentally fire actions, and I compare X vs Y movement to decide if the player swiped left/right (lane change) or up/down (jump/slide). Finally, I show the important Project Settings tweaks—enable “Use Mouse for Touch” for easy testing on PC, and clear the “Default Touch Interface” so it doesn’t interfere. Once that’s done, you can press play and the touch controls work cleanly.
