[@SpringDavid]

Hey, for anyone new to godot using a newer version (like me), in case it looks like the code isnt working after some moment in the video, try to check if the code hasnt changed how some things are called. Heres some examples: -"export" is written as "@export" now -"InputMap.get_action_list" became "InputMap.action_get_events" -"scancode" now is "keycode" (yes it applies to "get_scancode_string" too) -"is_action_just_pressed" didnt change name (at least not in the version I'm using)

[@koresaliva]

Appreciated!

[@maks-yn5xg]

also, if your interact input accepts physical input (like "E"), you have to scan for physcal keycode, like so: keyname = OS.get_keycode_string(action.physical_keycode)

[@TheRetroMax]

Another thing, if you guys are trying to set the path following platform in the tween_property it's not "unit_offset" anymore, it's "progress_ratio"

[@binyot5505]

@@maks-yn5xg for some reason it shows just "[]" instead of the key "E"

[@maks-yn5xg]

@@binyot5505 probably they changed it again in godot 4.2, so maybe look into change log for anything about inputs

@@GaryParkin Can you please explain what you mean by making the interact key return to the player?

[@GaryParkin]

@@NagiDev The code in get_prompt around 3:20 where you use InputMap.action_get_events(prompt_action). I can get the key by using InputMap.action_get_events( actions ), but OS.get_scancode_string is no longer valid. It doesn't connect to any variable coming from InputMap. I have a question pending in the forms. The closest I've gotten is var actions = InputMap.get_actions().find(prompt_action)

One of the best paced video tutorials I've ever seen. Thank you for respecting the viewers time. It allows people like me who used other engines to quickly pickup what the new function names, general behaviors, and workflows are without having to lug through all the zero-to-hero overhead the docs and other tutorials do. Even with the tutorial being for Godot 3, its taken less time to translate it to Godot 4 than it would to listen to most others drone on about its principles, long wind up jokes, and uncut clicking and loading.

Very useful video, keep the good work. One aspect in Godot and in 3d I'm personally struggling of is light, in particular interior light. I find very difficult set the enviroment light and in case of rooms the interior light.

what do you think about 3D in godot ! I like games like puppet combo games or fear to fathom do you think godot can handle this type of games ! many say it will lag and bad performance so i really want to know what do you think ! your tutorials are really helpful keep up

[@NagiDev]

Looking at the gameplay of fear to fathom, I don't think you'll have any problem making a game like it. The only aspect I've seen Godot struggle in is handling a huge number of physics objects (pretty rare case for most game projects) and even that can be solved by using low level languages to handle those parts. So, yeah, go ahead and give Godot a try! You would have a lot of fun ;)

I've changed some of the strings / nodes etc. so you may need to update to your own project or to match the ones used by Nagi in the tutorial; hope this helps. Thanks to Nagi for a great tutorial and the humour, this was the only code I was able to get to work with a few tweaks, while trying to learn Godot 4, first week trying the engine or game making for that matter :D haven't been able to get the platform working in 4 yet as tween code needs updating, sure I'll figure it out. All thanks to Nagi (www.youtube.com/@NagiDev) for his tutorial, I just updated for Godot 4 ####Interactable .gd - script extends StaticBody3D class_name Interactable signal interacted(body) #prompt message i.e. keymapping to press @export var prompt_message = "Interact" #Keymapping (Input mapping, project settings) @export var prompt_action = "Interact" func get_prompt(): var key_name = "" for action in InputMap.action_get_events(prompt_action): if action is InputEventKey: key_name = OS.get_keycode_string(action.keycode) return prompt_message + " [" + key_name + "]" func interact(body): #Print to console for debugging - optional # print(body.name, " Interacted!") emit_signal("interacted", body) ####Doors.gd - script extends Node3D @export var open = false var playback = null func _ready(): playback = $AnimationTree.get("parameters/playback") func toggle_door(_body): open = !open if open: playback.travel("DoorOpen") else: playback.travel("DoorClose") ####InteractRayCast3D - script extends RayCast3D @onready var prompt = $Prompt func _ready(): add_exception(owner) func _physics_process(_delta): prompt.text = "" if is_colliding(): var detected = get_collider() if detected is Interactable: prompt.text = detected.name prompt.text = detected.get_prompt() if Input.is_action_just_pressed(detected.prompt_action): detected.interact(owner) Note there are some compatibility updates required for 4.0 like updating 'extends nodes' to what you may have used, updating player.gd e.g. removing move_and_slide() arguments and updated functions. I'd created my own code at first but struggled with getting doors to work using alternative methods (different types of doors than the ones used in this tutorial but close enough for this guide to work with updates and without using bones.

Another issue I have is that the character still moves when the dialogue is displayed, don't know why. Could you help me with that?

[@NagiDev]

Hey! The prompt message not showing the key in Godot 4 is probably because you set the input map to use physical keys (which is default in 4). You will have to edit Interactable.gd script to have: for action in InputMap.action_get_events(prompt_action): if action is InputEventKey: key_name = action.as_text_physical_keycode() As for the character still moving, there could be a number of reasons.
