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!

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 YouTube 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.

[iakobs]

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

[chumptree]

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

[veylore]

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

[pietraderdetective]

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

[doogiedog]

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.

[mingle-hk]

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

[Vexatious]

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!

[CalmProto]

Entertaining and informative. Thank you.

[Justine-justin]

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

[antoniowagner]

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)))

[hrgamedev]

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?

[Nebular_Games]

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

[rendcycle]

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

[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

[ericwood]

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.

[hakimsmaili]

Can you give us an explanation of how to save the data, for example, the status of the player, the number of coins collected, or anything else

[andrejmaimakov]
