This ease my testing so much, thx. I am surprised this is not available with basic installation really useful to easily create in game test, worked as a charm. I tried at first but got a bunch of errors (Missing PhysX, win32 instead of win64, created for UE4 not UE5).
When looking here and there, they suggested using a bunch of timers, events and connections to do in game testing. Might not be the recommended way to test in game but for now, I am sold to the key pressed approach using your file.
To be honest that was one of the simplest things I solved so far with my unreal usage. (Work with Unreal 5.3 2023-12-15) Thx again!
