godot-FirstPersonStarter VS dialogic

I was rewriting gdscript to c# from godot-firstPersonStarter, but i can't move. I checked value of Velocity and it's not equal to zero, like MoveAndSlide function don't work.

Copied an fps boilerplate: https://github.com/Whimfoome/godot-FirstPersonStarter. And then added my character, ran it and its already struggling? Is this expected? or is Godot still only for 2D?

I used the First Person Starter template by Whimfoome, wich is very nice and work independently of keyboard layout.

Curious if this technique is already implemented here https://github.com/Whimfoome/godot-FirstPersonStarter

I made this game for the SAAM Arcade Game Jam- I used this controller to get me started: https://godotengine.org/asset-library/asset/424 It was much more difficult than I realized. The game is quite simple as-is but it still took me a long time to understand even basic concepts about game design. Overall, it made me more excited for future jams and I feel as though I have a decent base to grow from.

For some context, I'm an experienced (~10 years) programmer starting to dabble in game development. I'm learning to build various systems to gain experience and understanding, and recently I was interested in developing a dialogue system with an editor similar to what Dialogic provides.

Use something like Dialogic or (personal recommendation) Dialog Manager.

I used a Godot plugin called "Dialogic" to create it, still working on the themes and assets, so most changes made are cosmetic.

There are two great dialogue systems available for Godot, Godot Dialogue Manager, which is geared more towards writing things in a script, and Dialogic with a nice user interface, that is more artist-friendly (though direct script editing is also available). It also has more features (at least in the new version, which is currently under development for the upcoming Godot 4 and might not be suitable for production).

Here you go. You should try RC3 with this. https://github.com/coppolaemilio/dialogic/commits/main

Dialogic 2.0 is supposed to be Godot 4 ready (according to github https://github.com/coppolaemilio/dialogic)

For your second question, try looking at existing add-ons like Dialogic either for a ready to use implementation or as inspiration for how to code your own.
