I’m a beginner so forgive me but can someone explain why the index of an enum value would ever be needed if enum values are constant and hard coded? When would I ever not reference it by name? Also follow up question: wouldn’t directly setting the integer value (do you even call it the index?) functionally turn your enum into a dictionary of constants? Edit: kind of realizing the nature of my question is really just what use the integer values have? This video is immensely helpful but it only contains an example of using enums as mini state machines and I can’t help but feel there’s more to them, possibly?

I LOVE YOU

Thank you! simple and to the point.

You saved my evening. I can't use the start in scripting 😓 but my cells generator has a new brick. Thanks

Third option is the only viable one if you're loading in and out of the same scene (eg: intro and game, from an infinite runner), otherwise you run into a circular reference null error. If you still want to use PackedScene - which is very handy and artist-driven - just do: SceneSwitcher.switch_scene(next_scene.resource_path) #next_scene is a PackedScene variable, @export it so you can define it in the editor

Thank you so much.

Thanks! Very helpful

How I can use it together with CanvasLayer? I need to have health bar fixed at the screen, but it crashes with *Invalid set index 'value' (on base: 'null instance') with value of type 'int'*..

Hi Brett! I saw your game website and saw myself in you. Just wanted to say I'm already a big fan and I hope you someday return to this channel! You seem really cool.

I finally understood enums thanks to you

Great tutorial! However I've been experiencing problems when I was making my platformer game and every time I try to press the key I assigned the sound in a jumping function, the whole project crashes.

didn't work :(

Thank you for the tutorial man. However I noticed this recommended method by Godot official using SceneSwitcher introduces like 1sec delay in my case. I am testing it on my main land, and when player enters a house, i want to show the interior. if i use this: get_tree().call_deferred("change_scene_to_packed", door_scene) the scene switch itself has no delay and new scene got rendered in no time. But using SceneSwitcher.switch_scene("res://scenes/house_interior.tscn") there is like 1 sec delay. Does anyone have any idea why is it the case?

I really like your click game... and your teaching style..

yes Sir...

Thank You for showing this. You mad it informative and easy to get

Bonus points for teaching me about Ctrl+D

Will you make videos again? You are very good with explaining

I already saw somewhere "%0.2f" % damage when trying to round and and stringify the value, buy IDK why that works for 2 decimals.

this is so unbelievably helpful! i almost gave up coding several times just becuz i couldn't figure out how to make imputs and or change the Y/X axis :P

1:30 here Im running at 2800 fps xD lets learn how to max it

Hello good video, but im getting the error message that the root HealthLabel and HealthBar don't exist while they do in my code any idea how to fix this?

Thanks a lot once again, Brett! I really appreciate these natural, down-to-earth walk-throughs! They're clearly very well thought-out, fluid and informative. I'm keeping my eye on new material you produce on Godot going forwards! 🙂

kinda messy but great info, thanks

You know a tutorial is good when it gets straight to the point, and is less than 5 minutes long.

A good thing about doing it this way, is that you can expand the list - *backwards*. That is, imagine you have firetype double and triple, and only later decide to have a single-shot fire type too; you can put it in the enum list, *before* the double, and because everything is using the enum, it breaks nothing at all. You can also do things like have an enum and an array at the top of your file that are in parity, and use the enum as an index for the array, so that you can always just quick-access the correct array element from another class no matter whether you've changed things. I found that really useful when making some temporary debugging tools.

i was missing the ""_to_file" in that line, ty!

this is the sort of tutorial ive been looking for. too many are "just copy paste my stuff" cause they only show snippets of code without context, or just dump all their code into a two-three files

I'm inspired every more inspired to use Godot for all of my games

I care about computers and phones too all of my games going to be for PC and Android and iPhone I'm not publishing to console

I like open source because of I don't have to pay anything to use Godot that is why I chose Godot

Thank you so much! I've been Googling all over and couldn't find what I needed: my _process() wasn't being called after changing scene, and I couldn't figure why. It turned out that I'd completely misunderstand that the association between scenes and scripts is completely manual - so I hadn't got my script attached to the scene, hence why _process() wasn't being called. Such a simple thing, but hard to grasp without watching a thorough walk-through like yours. Cheers! 🙂

Thanks

Very inspiring - thank you! And... good luck!

Thank you very much for this - I really appreciate your thoroughness in going through how the workspace UI is constructed. I've been very, very confused by the interface. My big issue was understanding the hierarchy of the various panes. On the top-left is the current Scene, but I really couldn't figure where the parent tree of this was. When opening one of the demo sample games, I closed the scene and then it looks as though I'd deleted everything - so I couldn't then understand why the game still seemed to run! I really hadn't figured out that the 'res' list was effectively this top level in the tree; I assumed that resources were just artefacts to be referenced in the main project - and didn't expect them to form part of the hierarchy. Thank you!

this is useful for non game stuff too

Thanks, this was useful!

Thanks Dear

I found enum a few days back, using it for game state, really needed to know how to access it globally across scenes - thanks. I now know class_name :)

Super simple and to the point. Got a UI progress bar in less than 5 minutes! Thanks a ton for this tutorial!

The Thinkpad + PopOS is classic 😂

Do i need to download 750megabites of something i forgot every time i want to export a game?

Wow this is enormously helpful, I've spent a couple hours trying to rig together some janky progress bar behavior with polygon2d shapes when this is an option 🤣😭 Thanks for the tutorial!

Thanks for this tutorial. I was using change_to_packed_scene before but I decided to update to the call_deferred method. I still wanted to use PackedScenes, though, so I modified the code a bit. Here's how I did it if anyone is interested (so far it works just fine): func switch_scene(pscene: PackedScene) -> void: call_deferred("_deferred_switch_scene", pscene.resource_path) # pscene.resource_path grabs the path to the provided PackedScene and returns a string func _deferred_switch_scene(scene_path: String) -> void: current_scene.free() var new_scene = ResourceLoader.load(scene_path) current_scene = new_scene.instantiate() get_tree().root.add_child(current_scene) get_tree().current_scene = current_scene

Thank you so much for this video! It helped a lot :)

I'm anchored from a professional game dev trying to make my own personal project, and my biggest personal problem is distraction, so the "ruthless focus" point makes so much sense to me. I'm confident in my skills, but my time management is in the dumps. Watching YT vids with food, finishing vids, getting asked out of the room for a chore, dealing with getting DMS and responding, posting content, distraction by media when looking for music or anything else on the internet. Though I don't play many games in recent years, I watch too much content on YT of people playing games instead. It even leaks into my full time job efforts too. It's brutal. I end up taking out time I could have put from my personal project into job work so the job work is done on time 😅

How change text into int at Label?

Quite a good job.

I started learning godot and counting time was the wall i hit, i looked for scripts similar to what i wanted but timers there were in code and were more complex, i coudnt also find any explanation in my native language(not english) i stopped learning for like half a month but it turned out that i was idiot and there was a timer node that wasn't so complex. Thanks for this video, it set me back on track.
