A beginner needing help moving the character

Hi, I am new to Godot. I'm trying to learn how to create a character that moves in the scene but failed. So I'm looking for help here.

So far I've tried:

1) I read the tutorial here, followed every step, copy and pasted all the codes but it doesn't work. https://docs.godotengine.org/en/stable/tutorials/2d/2d_movement.html#introduction

2) I opened "Hexagonal Game" sample project, copied the code to my own project exactly as it is, but it still doesn't work.

Here is a screenshot of my code, copied from "Hexagonal Game" sample project exactly as it is.

I'm not sure what went wrong. Any help would be awesome!

It's probably because you didn't set your inputs in Project/Project Settings/Input Map The spelling has to be the same as the code.

Thank you, it works now!

Great!
