This works amazing, thanks man. For anyone who can be interested, I modified the for to this so the last one can fill all the empty space: float columnCount = 0; float rowCount = 0; for (int i = 0; i < rectChildren.Count; i++) { rowCount = i / columns; columnCount = i % columns; if(fitType == FitType.WIDTH || fitType == FitType.HEIGHT) { var rest = (rows * columns) - i; if (i == rectChildren.Count - 1 && rest > 0) { cellSize.x *= rest; columnCount /= rest; } } var item = rectChildren[i]; var xPos = (cellSize.x * columnCount) + (spacing.x * columnCount) + padding.left; var yPos = (cellSize.y * rowCount) + (spacing.y * rowCount) + padding.top; SetChildAlongAxis(item, 0, xPos, cellSize.x); SetChildAlongAxis(item, 1, yPos, cellSize.y); } Also someone write the script and put it on github so yall don't need to pause and copy for the eternity. github.com/IkeThermite/GameDevGuide-CustomTabsAndFlexibleGrid/blob/master/Custom%20Tabs%20and%20Flexible%20Grid/Assets/Scripts/FlexibleGridLayout.cs

For anyone having trouble with spacing causing overflow with more than a 3x3 grid: float cellWidth = (parentWidth / (float)columns) - ((spacing.x / (float)columns) * 2).... Should be: float cellWidth = (parentWidth / (float)columns) - ((spacing.x / (float)columns) * (colums - 1)).... Same for height. Thanks for the great video, keep it up!

is this true? did someone actually made a grid layout tutorial that is actually usefull!?

Hey, there are very few KZfaqrs who make advanced tutorials so please continue making these videos even when I think I already know everything about the topic I still learn something new from your videos.

When picking a font, read the font license VERY carefully to avoid copyright issues. I'm pretty sure Unity embeds fonts into the game, and most font licenses don't allow that.

Honestly, it's so refreshing to see someone finally talk about these things. As a UI designer myself, it always seems as these topics just fall flat for most smaller/middle-sized projects.

You go so fast dude! I cannot follow without pausing every second. Also share the scripts where possible. Awesome stuff

This channel is so informative and fun to watch at the same time, much more than other Unity tutorial channels I've seen. You definitely deserve more subscribers and attention. Keep it going, your videos are amazing and they help me with my Unity projects, thank you!

So you are telling me i just found this amazing guy who can code AND explain to me how it is done? No leaving out extra steps. Love it

For dynamic or flexible grid I always combine a vertical layout group and filled it with horizontal layout groups for the rows and then every horizontal layout group contains the "cell" elements of the current row. You could also achieve a dynamic grid by using the existing grid layout and update the cell size property in code depending on the total grid width / height. But still nice to how a custom layout group can be implemented and bookmarked for later.

I love how you explain what you're doing without making us watch hours of typing and debugging like many other Unity tutorials. Brilliant, right to the point, and right at my level of expertise. Subscribed, and thanks.

This video is a gold mine to learn, thank you.

You just simplified every future UI pain. Flexbox did the same for web development.

This is lit. Thank you for taking the time to show and explain such things, we all agree that the default Grid system is lacking some basic features. Cheers!

I usually don't comment videos. I was already subscribed to you but finding this video looking for a dynamic grid made me activate notifications and comment this. THIS IS AWESOME. Thank you very much!

As someone who usually abhors UI work in Unity, this channel is absolutely brilliant. Thank you for this!

(cellWidth

I cannot thank you enough for this. I was totally frustrated by the default grid component, but was too lazy to build an alternative.

I'm so happy I found your channel! There are very very few informative and high quality UI Unity tutorials like yours on the internet. Thank you for sharing the knowledge.

That's crazy how Unity doesn't have such useful thing out of the box. Thanks a lot!

This script saved my butt when trying to make a grid of n x n size. Thank you so much

This is incredible! Hands down the best tutorial about Unity UI I've ever seen, even general purpose UI implementation. Plus sharing the script itself is very generous of you, it's a must have asset. Subbed&Liked!

Thanks for making a great series of clear, factual and enjoyable videos. I'd love to see something covering best practices for interfacing your game's logic, variables etc to the UI.

How have I never seen this channel before?? You have some amazing videos that are very explanatory, concise, and easy to understand. Please continue making videos!

The only Unity channel that is based on real practices.

To people who are having overflowing issues with spacing, change the lines where you set cellWidth and cellHeight with these. Parentheses are very imporant here. float cellWidth = (parentWidth / columns) - (spacing.x / ((float)columns / (columns - 1))) - (padding.left / (float)columns) - (padding.right / (float)columns); float cellHeight = (parentHeight / rows) - (spacing.y / ((float)rows / (rows - 1))) - (padding.top / (float)rows) - (padding.bottom / (float)rows);

This is the best Unity tutorial I've ever seen for so many reasons. Instant subscribe

I love the venom anytime grid layouts are mentioned.

Thank you. I think this'll give me most of what I need to make my website simulator!

The best channel for unity tutoral with Brackeys

I'm speechless. This is amazing!! Incredible work bro.

OMG there is someone better than Brackeys. U R My new FAVOURITE KZfaqR!!!!!

For anyone needing the fixedWidth and fixedHeight I added this: // fixed width if (fitType == FitType.FixedWidth) { // calculated columns based on width and spacing float width = rectTransform.rect.width; colums = Mathf.FloorToInt((width + spacing.x) / (cellSize.x + spacing.x)); rows = Mathf.CeilToInt(transform.childCount / colums); } // fixed height if (fitType == FitType.FixedHeight) { // calculated rows based on height and spacing float height = rectTransform.rect.height; rows = Mathf.FloorToInt((height + spacing.y) / (cellSize.y + spacing.y)); colums = Mathf.CeilToInt(transform.childCount / rows); }

Hi! For enabling/disabling you can just do: panels[i].gameObject.setActive(i == panelIndex); instead of using if/else

I LOVE your channel!!! You always have exactly what I need!! I've watched every one of your videos now, and they're all just incredible! You deserve more subscribers, I wish there were more videos to watch!

I should check the comments earlier. Was sure something wrong, but still spent a hour trying to understand the logic, as I was sure in great videos like these there are no mistakes.

Thank you SO much for your videos. Unity UI has always been very frustrating for me, and you make it so much easier!

Really good video! Deff the best channel for UI/UX related topics by far

Wow, what an amazing tutorial! So educational, well-made, and perfectly paced. Thank you so much!!

This is great. I never knew I needed something like this until you mentioned it in the discord the other day. Thanks!

I’m an Unreal user all the way but your video was still so dang good and useful. Thank you! Unfortunately now KZfaq keeps suggesting Unity videos. Lol :/

Very good code, and really brings to question why Unity, 4 years later, still has the same stale grid layout component.

Super useful Matt! Smooth and clear as always! As the name suggests it is really flexible :D

Is there any way you can post the code on github?

Thanks for this awesome tutorial, now I am getting some confident and scale UI designs to the next level by programmatically.

I found your channel just recently and I love it

This is excellent work.

Love it! Grids are so important, and your tutorial is so great. Thanks man!

Yes! I've always dabbled in trying to customize the grid layout group component because of its potential for functionality (despite being lackluster in what it offers initially). Really hope Unity doesn't overhaul it too much in the future.

Really love your channel, every video is so exciting and helpful. Thanks for all the tutorials.

Where you multiplied cellSize.x / columns * 2 and cellSize.y / rows * 2 ,you can replace the literal 2 with (columns - 1) or (rows - 1) to fix the code for all capacities ie: cellSize.x = parentWidth / cols - spacing.x / cols * (cols - 1) - (float)padding.left / cols - (float)padding.right / cols; cellSize.y = parentHeight / rows - spacing.y / rows * (rows - 1) - (float)padding.top / rows - (float)padding.bottom / rows; Also, most of the brackets (except the ones I've added) don't do anything, because of the order of operations and commutative laws of multiplication and division. I understand you adding them anyway, as a safe practice from a logical standpoint. Amazing tutorial series, though! This helped a ton!

Informative and in depth tutorial on a specific topic.Thanks.

This is so super helpful!

I've been waiting for this video for a long time!

So, urm, I'm curious: are you aware that you are the best unity tutorial channel ever?

Every video is even more impressive as the previous one !! :)

Simply awesome. Sourcecode will be great.

Just wondering where you got the tab script at 9:01 from? I looked at the tabs video but i couldn’t find it. Thanks

Really useful tutorial. Thank you!!

Keep doing tutorials! It's very informative and your code is example of good code for me :)

It felt a little cathartic when you took a jab at the grid layout in the last video. After seeing that in this video as a UI/UX person I had to sub. One question though: Does this Flexible grid work with a content size fitter?

Great videos, my only complaint is not being able to see what components are on the parent objects before you get started. Also did I miss the creation of the "Tab" Script? - I saw TabGroup and TabButton. Assuming you made one off camera? Maybe one day you could do some tutorials for World Space canvas scripts xD

Hey man, this is great! I'll definitely use it to design my UI from now on. I already have a half-baked dynamic grid system, but it's only for dynamically initializing an inventory in a scroll rect. I can see that your solution can be easily adapted to that. Keep up the good work man! I love your tutorials!

one of the best channels ever

you should post more, you are so good dude, i learned a lot from you, thanks 🥇

The idea is good because it looks like professional game ui system. The issues is that there are many files and we do not lnow where to find there.

The biggest problem with the Default Grid Layout is that it assigns a fixed size for each child element and by doing so it creates major resolution scaling problems, especially when the aspect ratio changes. This works very well around the problem and scales accordingly to all aspect ratios and resolutions.

They should take this and make it the new standard layout group.

Great content mate, hope to see more UI stuff in the future ❤

This is amazing bro. Thank you :)

Why is it so hard to find advanced tutorials/guides like this? There are million of beginner tutorials but no advanced stuff. Really depressing

if anyone has problems with understanding and work of cellWidth and cellHeight I think this version will be better: cellWidth = (parent.width - (spacing.x * ((float)columns - 1)) - padding.left - padding.right) / (float)columns; you first get sum of all sizes and then divide it in columns count.

Thanks, It came in handy for my current project.

I would love to see a video on how to make those buttons and how to outline them like you did

This is amazing. Thanks for the great work

Cool vid. For the project I'm working on I went for a 3D type menu system that navigates like a point and click adventure. Though at first I was using a typical 2d tabbed grid Ui. It was slow and boring to navigate, The 3D menu made things so much more fluid, fast and fun to navigate. If you are going to make a game with lots to do like my project. Might as well make the menus/inventory fun to open up. That the issue I have with lots of AAA games the menus are slow and boring to navigate and for most open world games you spend to much time in them.

Great explanation, will use this in one of my future games

Excellent! Keep it up Matt!

I would love it if you could make a vud on crating Fallout/Skyui esque list inventories, with a 3d preview.

If anyone needs this to work with a content size fitter take a look at doing something like the following below the rest of the code described in the video. This is just a draft and needs expanding on to fully work with the different configurations of the component, but it should give you a good base to work from - if (GetComponent() != null) { var totalMinWidth = (rectChildren.Count * (cellSize.x + spacing.x)) + padding.left + padding.right; var totalMinHeight = (rectChildren.Count * (cellSize.y + spacing.y)) + padding.top + padding.bottom; SetLayoutInputForAxis(totalMinWidth, -1, -1, 0); SetLayoutInputForAxis(totalMinHeight, -1, -1, 1); }

feels high quality

Absolute top notch video! Thank you so much!

I only want to say thanks for all this such amazing job are you doing. ❤️

Every single video on this channel makes you doubt that unity guys know what they're doing.

This is an amazing tutorial, nice work!

Your videos are awesome mate! Thank you!

Loads of thanks for this video

I added this so it works in a vertical scrollview: if(fitType == FitType.FixedColumns) { rectTransform.sizeDelta = new Vector2(rectTransform.sizeDelta.x, (cellSize.y * (float)rows) + (spacing.y * (float)rows) - spacing.y); }

Thanks! This is really neat solution! I've (tried) to create something similar, but it wasn't nearly as clean - and I think I just used grid layout group + script that modified grid child sizes...

I love You, You saved my protect.

Great Tut. Thank you so much for teaching this.

WOW!!!!! this is very useful .thank you GDG~

Awesome tutorial, thank you very much!

This is awesome buddy 🤩

Great Found what I was looking for.

fantastic tutorial, thank you

great tutorial, exactly what I am looking for. I wonder if you have plans to add a scrollview to the custom grid layout, which would be extremely useful.

What sprites did you use around 3:30? Looks like you had a bunch of simple 2d sprites that would be good for UI. Was that an asset pack you could recommend or did you make them yourself?

Could you add the source code? I can't get this quite right...

That looks so cool!
