NOTICE: If you're having trouble seeing your tiles, ensure your sprite renderers alpha are set to 255. Sometimes it defaults to 0. Part 2 has been released: kzfaq.info/get/bejne/nJugoJVq3s7FhKc.html It includes additional functionality like unique tile logic, game flow, unit moving and attacking! Did you enjoy the video? Let me know so I can continue making helpful content!

Even the simplest tasks seem impossible if you don't know how unity works, it's like looking at the flying board for a plane

For the offset bool you could use: (x + y) % 2 == 1

All that in under 9 minutes! Tutorials are on par with the best on YT. Thanks.

This is a great video! You were able to communicate in such a way that I was able to understand what you were doing and how the code works.

Few minutes into the video and I already knew that this is an instant like and a sub

Most understandable grid tutorial ever! Thank you! I had problems with activating hilight object, and solved it with adding hilight color field into "Tile Script", and empty "backupColor" variable, that saves renderer color on mouse collision enter.

These tutorials are really clear, concise and you also explain some of the principle behind the code instead of just saying "type the code that I am typing and it will do what you want". I am subscribing. This tutorial is giving me an idea to make a small game for my portfolio, thanks a lot.

Instead of casting _width and _height to floats, you can divide them by 2f, it will result in a float.

The visual studio text is too small, pretty difficult to read. Other than that pretty good tutorial.

Imagine not liking this video... perfect video! Short, clear, easy to follow. Keep going!

Thank you for this wonderful tutorial! I was wondering why my colors didn't alternate after I added the sprite renderer and isOffset boolean, turns out my colors were all transparent! Make sure to check whether your Alpha value is at 255 to avoid the same problem I had :')

I looked for any sort of video tutorial, blog post, etc explaining this in 2020. Thank you so much!

The Cameraposition based on the size of your grid was what I needed!

Clear, concise instruction without fast forwarding to a speed no realistic human could follow. Probably(why lie? you definitely are) one of the top three cleanest and most efficient coders for Unity tutorials on KZfaq.

Thanks for the tutorial, was very cleary and for non english speacker it was very simply to understand you without subtitles.

This is a magnificent tutorial, thanks champ!

Absolutely brilliant tutorial, thank you very much for your work!

Personally, I think storing the grid in a data structure such as a two-dimensinal array is nice to work with. To extend this, if we had a three-dimensional array we could store layers of grids, that could represent house floors, underground floors, etc.

Very nice video: clear, informative and easy to understand. Thank you!

Watching this at 50% speed but wish you could pause 2-3 seconds after you swapping the screen, so I have time stopping the video and finish typing :-) But anyway, your videos are very helpful, so thanks for your effort!

Would look forward to more board game type of videos!

Would you be able to give an example of how to use the GetTileAtPosition function? Just to do something like displaying that tiles name to a debug menu or change a clicked tile to a different color?

You should mix in some devlogs that will be sooo cool.

Great video, really taught me a lot of stuff in a short time.

instead of centering the camera on the gird i wrote: Instantiate(_tileprefab, new Vector2(x - 4.5f, y - 4.5f), Quaternion.identity); its alot easier and if it doesnt line up properly then you need to play around with" 4.5f"

you're my fav tilemap guy right now!!

Thank you for your tutorial, that's a nice way to create a grid.

Ty so much dude.

Great video! straight to the point.

Great video! I followed the whole thing and duplicated it perfectly on my end. However, when I run it, I find that the tiles are not visible to the camera. The green colors do not show up. However, I can tell that the core functionality still works because the highlight comes up as I move my mouse around. I'm using Unit 2020.3.29, maybe that's why? :) Thanks for the tutorial!

Much love for this!

Thank you alot. Im learn how to make a game rn, this guide help me alot

When instantiating your dictionary it may be good practice to pass in the capacity (width * height in this case) of it as to not consume more memory than necessary whenever the dictionary needs to resize its capacity as you add more tiles. It may be also be worth to consider using a 2d array if you are nit picky about performance and memory as you don't have to save a key for each tile. I would only suggest this if you plan to make a giant array however, may not be necessary or even optimal for small projects.

@Tarodev Thank you brother, I learn so much from you.

You saved me tons of hours of work!

wow it in detail works! Very good job

Hi I'm just getting started with Unity, I'm sure I've messed up something simple. Whenever I call the Tile.Init(Bool) function all of the tiles are positioned in the one spot and the color doesn't change. Any help would be appreciated.

Would you mind explaining why you prefered to self-create a Grid system instead of using the actual Unity Grid and Tilemap system? I'll be really glad if you do so because I've already seen another youTuber's take on Grid as well (CodeMonkey's) and both of you decide to create your own versions instead of using Unity's. Is there a reason for that? Thanks in advance!

Hey, so this is a great tutorial and I was wondering if you could clarify the _renderer.color = isOffset ? _offsetColor : _baseColor; Is that just an if/else statement written in a single line? _renderer.color = (if ifOffset is True, _offsetColor, else _baseColor)?

fast, clever video, amazing!

You deserve more subs thank you for the tutorial.

For anyone who can get the highlight to appear change the layer for the Highlight 2D object to 1.

Aren't these 'OnMouse' methods actually a raycast? I guess that for huge grids it would be more performant to create a single raycast from the mouse position and check what's colliding instead of a script for each tile. Anyways, I love your content. I'm recomending your videos to a noob friend of mine who is starting with Unity. He's super motivated thanks to your videos! :)

Instead of moving the camera I instantiated my tiles as my gridManager's childs and moved my grid manager to -_height/2 , -_length/2. This way tiles are still starting from the position 0,0 relative to their parents.

If anybody has invincible tiles, dont forget to change where you change the color the saturation.

Very useful tutorial! thank you very much

Great video! I'm following along, but for some reason the Init function is making all the tiles not visible to the camera. I'm not sure how to fix this. I'm on 2021.2.7f1 if that matters.

Thanks for this. This was super good and simple

the new brackeys is looking good.

Saw your video in reddit, decided to sub, will be back today and get this tutorial going, thanks for this!

Very good tutorial!

Can somebody help me? I've done everything the master said in the video character to character. After adding the code to change the color of the tiles, the tiles stopped appearing and yes my sprite renderer was not turned off.

How would you go about creating an outline around each grid cell instead of coloring each grid cell like you did in this example? I tried adding in an Outline component but this did not work.

Hi, I am getting an error like this can any one please Help me? UnassignedReferenceException: The variable _renderer of Tile has not been assigned. You probably need to assign the _renderer variable of the Tile script in the inspector.

best easy board ever

lol this is the first tutorial I see naming a spwned object so it never occured to me that was possible

This is very useful, thank you!

Any ide why none of the tiles show a color? I can see the outline of them when I click on them, but the base color and offset color are not showing up when I click play.

rly good video man

FACTS!!!!!! Thank you so much man, you're the best!!!!!!!!!

哇哦，太酷了bro，非常感谢你的教程👍

Amazing!TYSM!!!

It’s not working.. I’m gettin a singular tile not the full grid

Completely agree. Aweso video

You can use Manhattan distance for the checkboard pattern: (x+y)%2

Thank you so much!

Level up your boolean game! In calculating the offset one might want to use (x%2) ^ (y%2). This is the xor operator and it is true, if both values are different, so 1 ^ 0 == true and 0 ^ 1 == true and false otherwise.

Nice tutorial

hey, i am having trouble trying to shrink it down. i want to make it all 10x smaller, so x=1 y=1 is now x=0.1 y=0.1 do you know how i could do this?

Hello, Just wondering how the GetTileAtPosition function is supposed to be used? Every way I have tried to use it, it has returned a null value and never a tile.

Awesome tutorial man, you just got a new subscriber :) I have a question for you, how different would be the process of achieving this, but in 3d? i.e Final fantasy tactics or Vandal hearts, in which the world is isometric 3d and you can rotate the camera in 4 angles?

Thankyou for this

Feel like I'm kind of falling at the first hurdle here, I don't have the option to make a 2D object. I thought it might be something about Unity's weird multiple render pipelines but no matter if I use URP or specific 2D, nope, still no 2D objects?

Hey! Is this system incompatible with the inbuilt Tilemap/Grid system of unity? Fx. You're making a custom Tile class, while there already exists one in the Tilemap package of unity.

Thanks, good video :)

Can this work with Hexagon tiles? Your video is very helpful

My tiles are invisible, any idea why? I can see that they are created in the scene but they have no color in neither game/scene

For me, the tiles are being instantiated 1 pixel apart rather than the size of the tile, which in my case is 75. "var spawnedTile = Instantiate(tilePrefab, new Vector2(x, y), Quaternion.identity);"

i don't know what fails, but i can't put my tile prefab into the grid manager, as he does at 1:28 i would appreciate some help

This was helpful, but not well explained. This would show you how to do it, but not why you're doing things, along with it being very fast between transitions. Things such as the spawnedTile section - I knew what was happening as I have messed around with grids in GMS2, but if I hadn't I wouldn't know whats going on. I didn't really learn what any of the functions did, so I spent time googling most steps to understand what I was writing.

Wondering if you could zoom in more on these tutorials because watching them on mobile is quite a pain!

amazing

Nice tutorial, thank you :) However, I have face the problem in the highlight section as the highlight color doesn't show up at all when I place my mouse to the tiles. Do you have any advice to fix it? Ps: My tiles are "Sprite Image" instead of "Color" and it seems like my Unity doesn't have the option "2D -> Sprite -> S̶q̶u̶a̶r̶e̶" for some reason...

What are the different ways to highlight tiles in Unity? What if I need to cast a shadow under object I am going to put? How to highlight tiles that are already occupied and those that are free?

Thank you sooo mch

What's the difference between this and the grid component

Hey there, I'm new on unity programming and I was trying to follow the turotial but for some reason the "Init" in 5:07 gives me an error... I copied everything from the code correctly, I don't know what could be wrong...

things worked fine :O . Though my tiles keep dissapearing visually. They are there! just, not visible :/

Why is the Value data type in the dictionary the Tile Class, not the GameObject?

Hi everyone and Tarodev, I love to use events like OnMouseEnter etc. but can you tell me if there is any performance difference between onmouseenter-exit and raycast system? I love to use both of them. Which one should we choose?

I have a problem with the camera the width is fine but the height go beyond the boundaries of my camera and I have no clue how to fix it

Thanks alot.

is it possible to use a tile set this way tell it to grab certain tiles from a tile set to do a random generated grid map

Hey! Thanks for the tutorial! How would you do this method with a flat-top hexagonal grid?

Good pace! The video is a bit blurry, hard to see the code on my screen.

Isn't it kinda redundant to create grid when tilemap itself is already a grid ? It contains methods for specific tiles, tilemap size, etc ?

Hey for the offset you could have done "(x + y) % 2 == 0"

Like it very much

will it lag if i put too many lines of code in the tile prefab
