Amazing tutorials so far. The engine is becoming way easier to explore on my own now.

[@dightrox]

Omg I'm so glad I found this. I was trying to make a game right into unreal, but this is so much easier and user friendly and you just make it SO easy to understand and follow along. I'm only on the 2nd video and I feel confident and want to learn more! THANK YOU!! for the time you put into these vids to help others. WE APPRECIATE YOU!!!

[@zzzzzzzzzzzzzzzzzzzzz-z1n]

FIRST LETS GOOOO! Your tutorials helped me get into Godot, now I'm 3 years into it and have learned so much, now I just have to finish a game, lol.

[@thejoeblowshow]

Yes! There are some, like you, sir, who are "natural born teachers." Thank you for such a fantastic and easy to follow tutorial series.

[@captainclamboat]

Okay, after this second lesson I'm grinning. It's exciting to see the technical stuff turn into physics objects! Looking forward to the rest of this series!

[@ZealotPara]

This is a lot of fun! Before watching the next tutorial, I wanted to play around more with what I learned here, and I even figured out on my own how to add proper collision to prism shapes! It's so satisfying seeing them fall and land in a natural looking way for their shape. I just randomly today decided I wanted to learn game dev, which I've never considered before because I never thought I was smart enough, but this tutorial series has been amazing so far. Thank you for sharing your knowledge!

[@ClintCarlson]

Amazing teaching. I've been doing other tutorials but love this series highlighting the little tips and hints along the way. thank you!

[@hipojoe]

Thank you so very much! I am using Godot based on your videos to create a terrain generator for my work. SO MUCH EASIER (and nicer) than making my own engine, which I have been doing for years!

[@mavinpo]

Dude. I struggled learning c# coding for unity to make games. It was a real turn off. Your videos are so user friendly and showcase how EASY Godot is, it's really inspirational to make games again. Live the series so far. Please don't stop. You're a good teacher.

[@Here_is_Waldo]

You can use Godot's built-in language. It's very similar to Python and is much easier to use compared to C# for someone who has never done any programming.

[@WeirdBrainGoo]

This tutorial series seems great for kids and teens who want to learn game development. I like your style of teaching, making sure everything is clear and easy to follow along. Personally I think calling it the box's boundary sounds more intuitive than force field, but maybe that's just me. I tried what happens if you try to enter the scene as a child of itself, at least in Godot 4 you just get a warning and it won't let you do that. :P

[@Ghostpants446]

Holy crap man you're such a good teacher thank you!

[@eisenspanigel67]

Thats so simple. Nice.

[@aulusdeek]

You also can save the Block as a .res file and drag it from the FileSystem Dock on the Node3D Root Node.

[@timothyn4699]

that grouping "don't allow selection of child nodes" is handy 12:37

[@NobleAbsinthe]

I'm at 19:53 what would be the issue if we made Rigidbody3D a child of a 3D scene node like in level 1. We make a new scene, start with 3D node and then have the Rigidbody3D as a child. As we can see it already is in the menu, so why do we start the root node as a RigidBody3D? I think it would semantically be the same...

[@profcelsofontes]

the mesh menu (top center) + create trimesh static body options is the fastest way to add collision

[@lagpostg.r.y9955]

I BEEN TRYING TO FIGURE OUT HOW TO MAKE AOLID GROUND FOR A LONG TIME THANK YOU SO MUCH

[@VivianAblivian]

There's some stuff in here that helped me fix some very basic but very annoying problems I've been having with making 2D games in Godot. For example: I didn't know that "Group Selected Nodes" button was a thing, or rather, I knew it was there I just never bothered to figure out what it does.

[@sporeolegy]

Wow! coming from unreal, godot 4 seems so much more intuitive and not at as clunky.

[@TextoAmarillo]

Thanks 💙

[@martinchudoba6945]

Fantastic

[@DenBlackburn]

Ive also come from Blander and ive used blenders own gameengine but blender hove not worked on the game engine for a lot of years now, you can try UPBGE a branch of blender that adds more to the game engine, but this GODOT has me very interested, thanks for the starters guide, it speeds up things knowing where to look for object properties and so on.

[@quintinwood4397]

If you drag a scene from your file dock directly in your node tree, it will instantiate it.

[@Shiromaru.]

u r legend, thx a lot

[@tuxedoblackfoot]

22:30 This feels like a challenge. Put a scene inside itself.

[@byucknahthered3914]

May I give a suggestion? You mentioned you are a High School teacher, right? I am assuming when teaching a class you show how to do something then provide an exercise so that students can practice what they just learned. I mention this because one of the more well known Godot tutorials for 2d games does this. They teach you how to use the features then give you an exercise, asking you to pause the video and try on your own as best you can, then when you un-pause they quickly go through the process which reinforces if you understood the steps -or- so you can see where you might have messed up. Early on this stuff is super simple but as things get more complex it's kinda handy to have exercises. For example, you could have made an exercise saying "Go ahead and try to make a new scene for another falling object, but this time try to make a sphere instead of a cube and add it to the level scene. Pause the video now and go ahead and try." which would give the viewers a chance to try and put what they just learned to the test but also changing it ever so slightly (Sphere instead of Cube) so they have to experiment a little while not fully alienating what they have been taught. Just my two bits of criticism, the videos are awesome and very well done/educational but I think giving exercises at the end of each lesson might help cement how to do things in a persons head.

[@f3b]

Again, amazing tutorial, very UpToDate to the current version. I was wondering is there a possibility to automatically match the collision size into the mesh itself ?

[@Stark_Ibrahim]

I want to learn how to change the player's path when I move the mouse. Can you do a lesson?❤

[@NandaRiziq]

awesome tutorials! just wondering will you be making 2d godot 4.x tutorial soon? i want to learn 2d in godot but i dont know if your godot 3.5 tutorial knowledge is transferable to godot 4

[@BornCG]

A lot (most) of the knowledge from my previous Godot 3.5 tutorial series is transferable, though they changed the names of a few nodes, and some GDScript code has changed slightly, enough to be a barrier to people just starting out programming unfortunately.

[@BornCG]

Thanks! ☺️. .. this course, my full time teaching, and life, are going to keep me busy through to the new year (there are 24 more lessons to edit and post, 26 in all) .. there will be another course after this one ... I have barely just started thinking about that at this point. 🤷🏼‍♂️🙃

[@lukeomatik]

Low effort question: since I don't know what is the correct definition of `scene` in godot context (i will look at it asap), not considering the re-usability of the assets, what is the difference between (A) creating the "falling cube" in another scene then link it to the main scene (like you did) and (B) creating a RigidBody3D with MeshInstance3D & CollisionShape3D directly into the main scene ? and again: not considering the re-usability of the falling cube asset

[@inyagi3107]

Hi at 6:46 you click the drop down arrow but for me nothing comes up :(

[@majesticchicken3213]

Finally❤

[@davestomper3428]

This is a great series I really like the attentions to every little detail one question for you is if I am making a 3d platformer scrolling can I just attach the Light node to the camera Then position the way I want my light and let it follow the light throughout the game?? this way I am done with lighting unless I need a special light color or something.

[@BornCG]

You could, though directional lights extend automatically through the entire world already, like a sun.

[@departuream1440]

For the floor, why did you choose a cube instead of a world boundary collider and plane mesh?

[@samvisser9408]

Hi, great video! I'm having problems playing a scene though - whenever i try to i get a pop-up saying: could not start subprocess(es)! Any ideas on how to fix this?

[@thatcardiologist3874]

So I've played around with both Unity and Godot, learning the basics of each. I'm kind of torn between the two though.. I love Godot's clean interface and it seems a lot less cluttered than Unity's. However, some things seem unnecessarily complex in Godot. For example, you have to create a StaticBody3d, a CollisionObject3d, and a MeshInstance3d all to create a simple cube.. In Unity you just add a cube. Even adding a color to the cube seems oddly complex. The coding also seems more complex in Godot. For instance if you want to detect if the mouse touches a gameObject in Unity, there is a built in function and it's super easy. However, despite making numerous google searches on how to do it in Godot, I still don't know how to do it.... Which should I choose???

[@AeroAndZero]

It depends on what are you targeting in the future. For example, if you want to work in a AAA company with a big team then you should definitely learn Unity as it has industry level tools. However, if you want to make a living out of being a indie game dev then you are free to choose godot as it will cut down many costs. Learning both's basics will definitely be useful in the future. I would recommend trying out both as you are just a beginner. Try to make a simple project in both and see which one works out for you :)

[@ravenanne1734]

I know this is a month old, but some people may still see this so I wanted to clarfy, the way he does it here is more complicated than usual! There are shortcuts already built in Godot that he doesn't mention, probably to avoid confusing people. You can just make a shape using a MeshInstance3D and there's a button at the top middle of the viewport called "Mesh" that lets you give it a collision shape automatically, and a StaticBody3D if that's the option you pick. It's automatically the shape and size you need it to be so it's really convenient. It's designed to be modular; if everything is made up of smaller things, it's easier to customise and mess around with. I'm not sure exactly what you mean by "detect if the mouse touches a gameObject" but it probably does exist in Godot, just under an awkward name. The main problem I've had with Godot so far is that because it's so new, the resources are scarce. The stuff exists, just not described how you might like, and with keywords that won't show up when searching for your specific problem. I've personally been finding vaguely related things, learning them, asking Chatgpt for more information, and then seeing how that pans out.

[@jacobthomas1688]

for some reason, the boxmesh isn't appearing. I added the meshinstace3d node and chose boxmesh properly but nothing happened

[@kantinero37]

Whats the difference of change a meshinstance3d scale via its resource or the transform at inspector window? or is the same?

[@MrXlee1967]

With "CollisionShape3D" can I not just link it to a mesh and it auto resize to the mesh? is there a way of doing this? thank you

[@davidterry1801]

Hi! I don't know if you are still taking questions on a 3 month old video, but I noticed that with the CollisionShape3D, you can scale the size of the box either by changing the size of the shape as you showed, but also by using the transform section lower down in the inspector to adjust the scale. They seem to arrive at the same result, but is there a difference between the two?

[@izuna9815]

my directional3dlight has a warning it says "A light's scale does not affect the actual visual size of light", I'm pretty sure that I followed your amazing tutorial correctly, but what do I do to remove this?

[@StacieButler-h1n]

When I play the current scene after adding the floor (around time stamp 14:20), it is just gray and empty. It doesn't look like yours. :(

[@Strivarn]

Change your camera position

[@noob0168]

Why can't I create collision same size with the mesh there is an error to it

[@learningconfe]

shadows are not supported when using the gl compatibility backend yet support will be added in future release in godot any help withe would help

[@TheDerekCrosson]

Anyone know what camera position and rotation I should use to see the floor? Currently I have: Position: 2, 0, 5 Rotation: 45, 0, 0 Scale: 1, 1, 1

[@tinyrandomthings]

what is the idea behind having separated collision shape and the object/the shape?

[@BornCG]

Modularity. The collision shape is a component that appears in different types of objects: static bodies, character bodies, rigid bodies, etc.

[@tinyrandomthings]

Oh, got it. That will make the code base much more efficient and neat. Different shapes may just have the same collision mechanism.

[@tinyrandomthings]

Appreciate, sir!

[@Rock_yeah]

Something that i noticed is that theres no random factor its always fall the same way

[@Bomba_Game]

27:24 its an actuall smooth quarts slab

[@what-err0rs]

The collision isnt allowing me to resize it. (Please make its scale uniform error) after typing the # on the axis and also manually moving it and typing it on the axis. Still an error

[@what-err0rs]

Im not making a platform fighter anyway, but I'd like to have a ground to walk on XD

[@PaintedCrow-tu7up]

so for some reason my block is falling but it wont tumble or interact with anything else. i just have a stack of shapes that shouldnt be able to stack. what am i missing cuz i followed your instructions to the letter.

[@jackthemunch123]

i had the same issue but look at your attachments and check and make sure that collision shape 3d is the child of the floor not meshindtance

[@digniii9477]

the option "new boxmesh" doesn´t appear for me

[@diggiilife8596]

i am having an issue and i cant figure out how to fix it, when ever i set the mesh of the MeshInstance3D to the cube it becomes REALLY huge, unworkably huge, and Godot says its 1x1x1, i dont know what to do

[@mannylight4280]

zoom out. it starts you pretty close up

[@diggiilife8596]

@mannylight4280 I did, but I had to increase camera speed, which wasn't fast enough to easily move

[@louptreize]

thx for videos, why don't you resize the staticbody3d directly instead of resizing mesh then collision (for the floor for example) ?

[@BornCG]

That's correct! In fact, way least in prior versions of Godot, scaling the physics body directly would cause issues apparently.

[@TheTrue_Burger]

How would I make this in first person? btw, I love your tutorials!

[@mrtwinky0v034]

wish i found this. the older version that was made 4yrs ago was so hard for me to follow becouse thay changed every thing

[@jackthemunch123]

i need help with something, when i drop the cubes in the scene they just go through the floor like it’s not there

[@thecupcakehey1608]

Do the cubes also have a collision node?

[@Glimmer11]

Could anyone explain to me why we need to create a new scene to add gravity to object?

[@BornCG]

You make each object as its own scene so that you can make instances of it (copies), not so that gravity can be added to each one.

[@Stoodknight]

why does my block keep falling through the floor?

[@ningyi5727]

why not a plane mesh?

[@BornCG]

Later in this project our level will be made of blocks that are easy to ‘paint’, so I just kept it simple and consistent in this earlier lesson. You could use a plain mesh with a block collision shape with its top just matching the plain.

[@Mythikal13]

made two cubes fall, this is huge guys
