On the top (Event BeginPlay) for the “Enable Input” function I’m able to define a controller. But this seems to be not possible for “Get Gamepad Left Thumbstick Y-Axis” etc. on the bottom. How do I define which gamepad input is selected for those?
Found the solution and am posting here if anybody runs into the same problem:
You’ve got to tell the engine that there are multiple players (I thought this was automatic, since 1 controller was recognized automatically)
→ this can be solved by creating local players in the Level Blueprint:
then you can duplicate the first actor in the map and assign an other controller number to it (I had 0 for the first one and 1 for the second one) - and it works.
This video showed how to do the setup pictured above:
