Godot 3.5: Let's Build a 2D Platformer!: Part 25 (Keys & Doors!)

[@Grobusck]

Dude you are my little brothers high school teacher! I used your videos in high school too! It’s so cool that my little brother know you and I had no idea you taught in my city!

[@heartbreakandmotorjive1867]

I left one of your playlist running all night while I slept. I woke up and decided to subscribe. When I hit subscribe, it gave me an error even though the ui showed it worked. And when I hit notifications, it gave me another error. Don't worry, I restarted the KZbin app and went back to your channel and it worked. I've never had that happen before, but I thought it was interesting after watching you script in Gadot in for hours. 😂😂😂 Great content! I started making a game in blender about 13 years ago and then life happened. After watching your simple 3d game in Gadot tutorial I'm thinking of revisiting it. You're a great teacher! Thank you for sharing your knowledge. I'm going to download Gadot and start messing around with it.

[@veylore]

you taught me 3d and are now teaching me how to learn godot, cant thank u enough for ur vids over the years

[@BornCG]

That's awesome!

[@Sakura-c5r]

​​@@BornCGIs this the last part of this game making, or there is still other parts left

[@doogiedog48]

I couldn't get the teleport line of code to work in Godot 3.5.3 where the player was assigned the new coordinates of the other door until I used this line of code player.position = target.global_position. Great tutorial Colin. This is the best tutorial out there for learning the engine.

[@iakobs]

man, I'm coding doors and keys in my godot 3d game JUST NOW 😂😂😂 the timing!

[@pietraderdetective8953]

Your Godot videos are super awesome! Definitely gonna binge watch while code along.

[@mingle-h4k]

I have to confess this is the easiest tutorial about godot, event it is about godot 3.5 or even earlier, for me to learn godot 4.3, it still feels so smooth. thanks colin, after watching your tutorial, I had deciced to donate some dollars to buy you a cup of coffee for your great work, but it tell me I cannot donate from my area (China Mainland),, sorry for that. hope you can continue to do more tutorial for godot, really you helped a lot for us

[@chumptree]

Please do a tutorial on save and load! I'm having difficulty learning it and u make things so easy to understand!

[@Vexatious00111000]

Thanks colin! I feel like I have enough experience in Godot now to make my own features and mechanics. Would love to see more tutorials though!

[@Justine-justin]

Pretty cool, makes you think of all the time it takes to make a game.

[@CalmProto]

Entertaining and informative. Thank you.

[@antoniowagner8914]

Another great video. I also wish you a great 2023.

[@irayala]

interested in how to save progress in the game. are you planning a lesson on this topic? before that, I didn't understand the programming language in Godot at all. and he didn't know how to program. but after watching your training videos, I began to understand how it works. thank you for your work)))

[@ThatElfNerd]

Progress saving is definitely something I would like to learn as well, but considering that the tutorial series is completely built on making one, singular level, I don't know if that will be covered. As it is, I had to use tutorials from others, as well as experimenting with my own code in order to not only make multiple levels, but also level selection screens, and a code that recognizes individual worlds and levels. That's why it's always good to look up tutorials from other sources, and also check Godot forums. Sometimes you find things from one source that another source might not have talked about.

[@irayala]

@@ThatElfNerd , yes, I also watch other authors, but there is so little detail and clear on KZbin. I figured out a little about saving, I can save an array with different data and now I need to apply this knowledge to a game with several levels. here's the catch. but nothing, I think there are a lot of new and interesting things ahead))

[@EggsToMe]

Hey! I really love your tutorials, and i want to know if you will make more 3D Godot tutorials with the new version, they helped me a lot with making my games :D

[@BornCG]

Stay tuned! 🤩

[@rendcycle]

Hoping you will release tutorials for Godot 4. :-)

[@ericwood1185]

Hello Colin I finally finished all your tutorials and now I'm trying to add levels 2 an more how do I have everything carry over to my new scenes ? Please do a video tutorial if it's not easy to do ,thanks Eric.

[@Nebular_Games1234]

Great tutorials, can you make one about load and save. If you could that would be amazing!

[@hr78gamedev]

Hi, First of all THANKS for your excellent tutorials. I hope this is not an old questions, but could you do a mini tutorial on converting the project of this tutorials serie for Godot 4 , when it will be released as Stable?

[@zixuntan0417]

Thanks so much man!

[@andrejmaimakov8438]

oh nice a Video again, one thing, could you pleas make a second level and show us how we add everyting from the first one, i tried it but it all ended up a faliur and so im asking you to explain it in a Video, it would be verry halpfull, btw. i love your Videos and like how you are explaining it. 😀

[@muajin]

Hello! I tried to bring up the project in godot 4 but getting an error with velocity. Any way to fix that? net says to delete the error line, but can't identity which one that is.

[@richardodell3062]

not sure why but with Godot 3.5.1 var player creates errors but if you say var player = Vector2() then it works

[@QqQq-bf8bd]

i made 3d game in godot 3.5.1 and export apk, but not working in mobile. splash screen open and app has been stopped, 2d game working properly but 3d game not working in mobile (snapdragon, adreno) ,i will try single cube and camera but same result. please help what i do

[@ireneahlberg7491]

Great tutorial as always! But ... at about 1:33:00, when you add "player.set_collision_layer_bit(0,true)" in teleportState 3, I get hurt by an enemy being outside the door. Seems logical since I am vulnerable the moment I get visible. Moving the line to teleportState 4, gave the enemy time to move on and worked perfectly. I hope it's not cause I missed something in the code.

[@basiladeeb]

I have a question. How did you learn to do all of this? Is there a book maybe or a YT channel that helped you? And when you are stuck, what do you do?

[@BornCG]

I'm a high-school computer Science teacher and was a computer summer camp manager for years, so having a background in programming fundamentals has definitely helped, as all languages share many of the same concepts, but Godot's official documentation, online forums and tutorials and videos are all good places to pull from.

[@basiladeeb]

@@BornCG Thank you for sharing what you know with the rest of us.

[@shalanijayasuriya1873]

Sir my when I created the door my character is behind the door when playing the game, how do i make the player appear in front of the door ?

[@BornCG]

In your node stack, put the Steve player node below the doors. Nodes lower down in the stack draw later, therefore on top.

[@shalanijayasuriya1873]

Thank you so much very helpful video 🙏

[@Mr-Moka]

broo how to add video in intro game

[@fatimaanimation]

I did every thing the same and checked them many times even repeated them but still cant pass to the other door, sometimes steve appear from somewhere else randomly thet even not related to the door, sometimes he open the door and go to the other door but steve cant 'appear' literally he froze and disappeared, cant move, there is just shooting fire nothing else, I don't know what's wrong with it, but I'm sure 100% that I did everything the same

[@jameswong9756]

Strange. The Door can't detect the Key, Steve is carrying

[@jameswong9756]

The Key did not disappear from the HUD after it was used to unlock the Door.

[@rremnar]

This is just my opinion; but in your key code, how is it that you can assign a node to a node path? They are 2 different types. Since you are originally type casting the variable to a node path, it shouldn't be possible to assign it a reference to an actual node. What I am guessing is that the node path is a memory reference itself, thus allowing your little hack to be possible. IMO, that is just bad. Wouldn't it be better to move your HUD scene into the autoload in project settings, thus making it accessible every where? Though if you do change your HUD, scene to scene, you'd have to rename it. Or , if you don't want to do that, just create an additional variable to hold the node reference. Assigning a object reference to a variable of the same name, also seems bad. Just because you can get away with it in GDScript doesn't mean you should put bad concepts into practice. I bet you won't be able to do this in other languages like C# or C++. export(NodePath) var HudPath onready var HudNode = get_node(HudPath)

[@caiofernando]

As I understand, the program doesn't assign a node path type to the variable, it assigns the node path type to the exported inspector field. What he does is possible because the variable hud is still dynamic despite the type assigned to the export field. You can check this by assigning a NodePath type to the hud variable itself. It will return an error if you do so. You can't do what he did in C# or C++ because they are statically typing languages, but GDScript is conceived as a dynamically typed language by nature, so this is not a hack, it's a feature of GDScript.

[@ThatElfNerd]

I have to ask: Is there going to be a tutorial in the future on how to make hint blocks or hint zones where when a player interacts with it, it'll give them information on their next step? I've had people play my game who didn't know that wall jumping was a feature in my game until I told them, as they had gotten stuck on a level where you HAVE to wall jump in order to proceed. I imagine a similar issue could happen if I decide to introduce keys in my game, and the players make it to the door, not realizing that they were supposed to look for a key.

[@BornCG]

Godot 4 is coming up quick, so I am planning to start a new tutorial mini series project for that. A hint could pop up if you enter an area.. it could make a label or perhaps a secondary HUD with a label become visible, and then when you leave leave the area it could become invisible again. From the knowledge you've gained from the existing tutorials, I'm sure you can do it! 🙂👍

[@giantfrogstudios839]

Why did this series suddenly stop?

[@BornCG]

As I talked about in this video, the keys and doors mechanism was the last promised feature from the outset of this tutorial series. Also: Godot 4 was released, which brings a lot of changes. It's time to move on to the next project! (coming soon-ish)

[@MikeMcRoberts]

@@BornCG Cool!

[@iJokeOfficial]

please , a multiplayer game tutorial ?!.

[@LandBeyond]

You did all that stuff for the Key to make the HUD inside the key not being forced to a certain HUD, but then forced the texture of the key from "Key" and not have the "hud" manage in case the hud is different. Should have just called a function inside "Hud" with a bool. So it could manager internal variables and what texture, instead of making your "Key" know all this and if you change your "Hud" you have to have a specific variable and texture. Your hud couldn't alter the key texture.

[@BloohGameDev]

Hey sir, can you make a toturail on how to Pass Data Between Scenes in Godot

Sorry again, but please help, @export(NodePath) @onready var hud = get_node(hud) wont work in godot 4 i tried everything the error is Annotation "@export" requires at most 0 arguments, but 1 were given.

[@samuraihoedown4761]

In Godot 4 I was never able to get this to work exactly as described in the video (I got the export to work, but never the key texture switching from it). I setup the export like this: @export_node_path("CanvasLayer") var hud @onready var _hud = get_node(hud) Since I couldn't get the texture switching to work via the export node path, I removed the line that should have done that under func _onKey_body_entered(body): _hud.keytexture = load("res://ASSETS/objects/hudKey_yellow.png") Instead I created a new function on the HUD to do the switching there based on the hasKey variable: func load_key(): if hasKey: $Panel/Key.texture = load("res://ASSETS/objects/hudKey_yellow.png") else: $Panel/Key.texture = load("res://ASSETS/objects/hudKey_yellow_empty.png") I then have load_key() being checked here: func _physics_process(delta): load_key() On the Key, as part of func _on_Key_body_entered(body):, I have this line to update hasKey variable on the HUD: _hud.hasKey = true
