I have been banging my against the wall for a few days now.
Unreal doesnt have out of the box true menu navigation for WASD keys.
There are no tutorials online about it, I asked the Epic Dev communities, Discords etc.
No one knew how I could handle my Menu Navigation using WASD keys.
People kept telling me to move on but I didnt want my players to have to use the Arrow keys to navigate.
The other day the power went out so I HAD to take a break. I fell asleep and dreamt a solution. I immediately wrote it down on my notepad on my phone. The next day I sat down and wrote the code the way I saw it in my dream and BLAMMO it worked!
It is VERY messy, I am cleaning it up but I finally got WASD menu navigation with keyboard.
Woohoo!
Now I am going to work on a nice turning animation and a small slide when you are running full tilt in one direction and then turn suddenly.
Then I need to code that to work properly.
Then its on to Melee combat!
