How Input Settings Works ?

[raphael2228]

Hi, can you explain how the input mapping system works? I'm trying to implement it on my own project. But there's nothing displayed in game and when I quit I get this error "Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetUserSettings_ReturnValue". Node: Branch Graph: CreateInputMapping Function: Create Input Mapping Blueprint: BFL_UI"

Hi! Can you share some screenshots please? Is it this branch on this function that cause this issue?

Are you sure you added the Player Mappable Key Settings ?

Sorry I really don't see where the problem is. If it's on your end I'm not sure I can really help.

I finally found the problem. I didn't have the associated option checked. in new projects it's probably checked by default. but not if it comes from unreal engine 4 initially.

Oh, I should have thought of that. Sorry. But you managed to find the issue and fix it, so it's all good. Let me know if you have any other questions, and I hope your experience with my project will be great 👍

after check, the get enhanced input user settings returns nothing if I test it with a “print string”, unlike your demo.

Are you sure you have these settings in Project Settings>Input?

yes, the buttons work without a problem. i can move, open a menu. that's why i don't understand.
