Everyone told me that the scriptable objects are pretty hard to learn. But as always you made it much easier to understand and implement. You are life saver, man. Thanks
They are basically models. Don't know why unity gave them a different name and treated them as a new feature. It's baked into c# (and any other OO languages)
Can you explain how this would be used in a game? You can't go writing a new method for every single card you want to display. How do you reference the SO in code?
@@Kathayne636late comment, but you can always at least go with a switch case of the name of the card. So switch (name"): Case "Minions": doMinionFunction(); Break;
aha whoa. What great timing, I just started working on a card game prototype & never knew how to use Scriptable Objects, now I am debating if I should use this or JSON... or both!? 😦 THANKS BRACKEYS!
I love how quick you teach a subject. I see other tutorials on subjects like this that people spend an hour teaching. I am usually not looking to spend an hour learning a new piece of Unity, unless it really deserves it. But what you get across in under 9 minutes is perfect! Keep the videos coming.
I'm not sure what version of C# you're using but string interpolation is really useful for showing #s as text. You can do stuff like: Text.text = $"{numberVariable}"; You can even add stuff like :F2 after the number value or variable name to specify decimal places. It makes forming strings that have placeholder variables in them really nice looking. For example: Debug.Log($"{itemName} costs ${itemCost:F2}." as opposed to a bunch of concatenation or the old style where you include variables as parameters to some function.
This is by far the best scriptable object video I've ever seen. I wasn't convinced I needed to use scriptable objects in my project but this completely changed my mind. This is a masterclass in visual explanation as well at technical. I love this.

This tutorial works (**finally**) but the solution to a persistent error I was getting was to make extensions lowercase. Autocorrect or Autocomplete affected code in VS Code by changing "nameText.text" into "nameText.Text," and was changing "artworkImage.sprite" into "artworkImage.Sprite." Then Unity wasn't compiling as a result of the autocorrect/autocomplete changes. Thank you for setting me on the right track with this! I did not want to have to hard-code literally everything just to get a few cards to show up on my screen.
I wonder how this is affected by the new ECS scripting system. And how well would it be to use structs in scriptable objects when making new guns and such?
Wow i watched soooo many tutorials and couldnt understand then stumbled upon this video and guess what i understood. i wish u came back to youtube you really helped me a lot.
I like to imagine that the people over at Blizzard watched this and said "Why didn't we think of that?" and immediately went hard at work to changing their setup of the game xD
Captain obvious here - they already have even more advanced setup of how they store card info. In fact the card designers are provided with tools of their own to edit card data without ever getting involved with Unity (game part)
I know it was a joke and you will comment with "took it too seriously", that's why started with "Captain obvious here" implying I know it was meant to be as joke. Still shared the info since it fits in well with the video.
Thank you so much. I have been trying to learn about SerializableObjects for a few days now and this is the best thing ever! Clear and concise. Thank you!
I've just watched two videos about Scriptable Objects, including the official 1 hour long Unity video on their website, and they both just hurt my brain. You explained this so well, I'm going to be checking out the rest of your videos for sure. Thanks!

Yeah... Thank you very much for the information. It looks like everyone talking about Scriptable Objects take the "lazy" approach of plugging the reference for the object assets manually directly in the inspector. What about if the card is created at run-time and you don't have the possibility to drag and drop that asset in? Can you reference an Scriptable Object from the assets folder (without using the Resources.Load, since Unity discourages its use)?
Hey Gerardo! I am just after the same thing, if you can change the object attributes runtime based on user input. Lets say change the artwork based on the user input. Have you figured it out?
Same thing here. Even with using Resource.Load I can't figure out the correct type for loading the created assets. Resources.Load("xyz.asset"); would come naturally to me, but there is no type Script allowed.
Dude, you honestly helped me so much. For two hours straight I tried to create a scriptable object (using code instead of the unityUI). This is way more convenient.
Great start for 2018! ScriptableObjects are saints sent from Unity heaven! I use SO's to keep information about weapons, weapon lists, weapon attachments, ammunition, sounds, configuration setups, localization (very basic though), powerups. But the best thing is I have float variables that I can easily change to change how e.g. a weapon handles its recoil. I highly recommend watching Ryan Hipples Unite Austin 2017 talk (link: ruclips.net/video/raQ3iHhE_Kk/видео.html)!
Yep great for own organization, and even better to allow artists and designers to add and change content themselves while you're busy adding new features or smashing those bugs =)
How do you store and assign values like sounds that would normally be components? Brackeys only shows how to assign child gameObjects, not components :|
You simply declare in your ScriptableObject an AudioSource property for example. Unity will correctly display default components in the editor, and you can even write your own editor override to serialize custom components likeyou wish. But not sure I understand well your problem honestly so sorry if that does not answer your question, feel free to ask again..
But how would i make it that each card does something special on the board, like edwin damaging all enemie cards when he is played but tirion destroying a random card
Excellent video, thanks! I had watched the Unity made tutorial on scriptable objects a couple of times and followed that, getting a few pieces I understood. But now after watching your video, I actually understand scriptable objects instead of just getting components working without the needed knowledge to adapt it to my development needs, and your video is like 10x shorter!
I love Scriptable Objects ! I watched a video about those from the Unite Austin 2017 conferences. And it was awesome. Gave me so much idea to work with Scriptable Objects. So now, I'm just waiting for the Unity 2018 releases with C# Jobs, ECS in Scripts and some more stuffs to be fully operational !
Can you please make a tutorial on Easy Save or perhaps make a script or tutorial about how to save your games! By the way,thanks for helping i always support the brackeys team!
Been looking at a lot of camera tutorials for Unity, this is so far the best by far. You explain things well, and the camera mechanics are more advanced and better coded.
Hello, Is there a way to put the ScriptableObject in Array? Instead of manually assigning ScriptableObjects in the screen how about you get a randomizer and those ScriptableObjects in the array and let the randomizer choose?
Make an abstract class of "CardEffect", Give CardEffect an abstract method of ActivateEffect( ); Create all the Effects you want, as sub-classes (extend to CardEffect), then define the ActivateEffect( ) method for each different sub-class Add the CardEffect class into the Card like he did for cardName, damage, health, and etc, as a variable Then just drag and drop in whatever CardEffect sub-class you require for your various ScriptableObjects, like he did for the different Sprite images for the card --- If the above doesn't make sense, lookup how to use abstract classes, and everything will begin to make sense.
Would be cool if he expanded upon this and showed us how to add cards to a deck and then once you purchase the deck with ingame currency or real money you click it and it randomly picks 3 cards based on rng....
Should be easy to figure out. A deck of cards is just going to be a List of cards. Pick 3 cards- just random range between 0 and deck length 3 times, being sure to remove the picked card from the List each draw.
Perfect timing on this for me. I was just looking into scriptable objects the other day and I wasn't sure if I had fully understood them. I definitely do now! I'll be using these for the shop in my current project. Thanks for the great video!
The biggest difference is that prefabs also have transform and gameobject data on them which is not needed if the object is only used to store persistent data. ScriptableObjects are created just for that purpose and have alot less overhead. Also, if you change a scriptable objects parameters during runtime. The changes will be saved and not lost when you exit play mode and that is very helpfull for designers
Great guide thank you so much, really taught me a lot as a noob to unity, I have 1 question however, at 8:08 you mention that you can easily update these scriptable objects while the game is running, because you are just swapping out simple informaton. I can see this to be true myself, as I can drag and drop a new scriptable object into the field in the editor while the game is running, and I can see it update instantly. (Using OnValidate() ) My question is, how can I achieve this with script, so that I do not have to drag and drop? I would like to create a UI button that the user (who does not have editor access) can click, and have the object updated to show a new image. I am sure this is very simple to achieve, but as a total noob I have been having some real trouble finding the proper syntax to write this. I would be very grateful for any help you or anyone reading this can provide, thanks again for the great vid!!
I am not the best in programming, but maybe just saving the Transform of a object in an variable. An progress you can handle, what i can think of: 1. In an rpg you save the complete number of quests in a variable and the number of completed quests also in one an use simple math to calculate the percentage, or 2. you use an array of zones -> you go trough one and the counter for passed zones goes up. All in all i think it is not that difficult. Bit in terms of the boat i cant help you, im to bad for this
1. Create a plane for the water, trigger collider. 2. Create a boat out of very primitive objects, and add a rigidbody. 3. Write a script, that estimates the how much of the boat's bulk is under the water (in cubic meters), and add force to the boat scaling with the estimated bulk. 4. Adjust rigidbody mass, drag, angular drag and the force you add, and maybe add a little randomized force. Here u have a boat.
László Juhász so, basically you'll still need to create a script for every card that has some unique properties? I thought that maybe scriptableObjects had a better way of handling it but thanks!
Creating a class for each unique card is not recommeneded and will probably won't work well as you add more cards in the future. Instead try to create classes for effects and reuse them on cards (like drawing, dealing damage, healing and so on)
Is it really that many though? yes some cards really do have unique effect that only they can use and no other card can but when you think about it it's only small portion of the cards, most cards are using the same effect and even cards with more than one effect you can just have a queue of effects that will execute in order
+Mikhail Chetverkin You are trying to solve a problem that has nothing to do with ScriptableObjects. A ScriptableObject holds information that is relevant to its GameObjects implementation behavior. That is it. What you want the GameObject to do beyond that point (of what is can do within its lifetime) depends on what you give it. Create all the UniqueProperty sub-classes you need, then... Give each Card the ability to hold a List and define the call requirements of this --- Again the ScriptableObject will not only allow you to inject this behavior into the Object at runtime, but also edit the injection of data within the Unity Editor.
It's so fucking cool. I've been trying to investigate what the heck is that before but everything was so messed up, but in this video you made it as clear as possible. THANK YOU MAN
Yes there is. You use Start for when the Game Starts. However you can create a Script that extends from the Editor to Update it when the information changes.
To save data I use Binary Formatting. Here's a quick run through on the MS website: msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.binary.binaryformatter(v=vs.110).aspx
That is not true, you can modify data in SO at runtime and those changes will remain even after you finish the runtime ie. it will override data you filled in the editor.
Is there a way to create saved data for all platforms using a Unity script rather than having to save a different way depending on the platform? Example: Windows 10, PS4, WebGL ...
What do you mean a "normal Object"?, you mean a prefab? Or maybe an Abstract sub-class? What ScriptableObjects is trying to make simple is a design pattern known as Dependency Injection. "The goal of the dependency injection technique is to remove this dependency by separating the usage from the creation of the object. This reduces the amount of required boilerplate code and improves flexibility." - Google Search: goal of dependency injection If you want to use other coding models to achieve your goal, you're welcome to do so, but keep in mind you are using Unity. It makes the most sense to use ScriptableObjects, because it streamlines the development, version control, and overall management of your games data objects. --- If you still don't get it then I suggest you try to create a game that uses a large amount of items(and create different version of these items). Do it without SerializedObjects, then do a version utilizing this tool. You will quickly understand why Scriptable Objects are essential to anyone working in Unity.
I think what the question is asking here is, in the way that he used this Card class (Object) in this video he could've also just created a class that inherits from nothing that stores primitive values. Stored the actual values like name, etc. In a json file and loaded them at runtime. But the benefit of scriptable objects here is the editor helping do all the setup.
Nicely Done! i love learning from you. you motivate me, I was going to shift to web due to recession in game dev field in my country but i am staying because of you. Because i know game dev is Awesome!!!!

Brackey, I know you hear this a lot but I can *NOT* emphasis how valuable your videos are.
Hey can you make a video about how to optimize a Game for mobile devices (Canvas Scaler)?!

I recommend Unite Austin's video about writing high performance C# scripts - ruclips.net/video/tGmnZdY5Y-E/видео.html

Thanks brackeys
This tutorial works (**finally**) but the solution to a persistent error I was getting was to make extensions lowercase.
Autocorrect or Autocomplete affected code in VS Code by changing "nameText.text" into "nameText.Text," and was changing "artworkImage.sprite" into "artworkImage.Sprite."
Then Unity wasn't compiling as a result of the autocorrect/autocomplete changes.
Thank you for setting me on the right track with this! I did not want to have to hard-code literally everything just to get a few cards to show up on my screen.
I wonder how this is affected by the new ECS scripting system.
And how well would it be to use structs in scriptable objects when making new guns and such?
Wow i watched soooo many tutorials and couldnt understand then stumbled upon this video and guess what i understood. i wish u came back to youtube you really helped me a lot.
7:30 music starts playing. It scared the shi* outa me.
Very nice, looked at a few scriptable object tutorials but this makes it easy to understand
I like to imagine that the people over at Blizzard watched this and said "Why didn't we think of that?" and immediately went hard at work to changing their setup of the game xD
Captain obvious here - they already have even more advanced setup of how they store card info. In fact the card designers are provided with tools of their own to edit card data without ever getting involved with Unity (game part)
You took a joke too seriously
I know it was a joke and you will comment with "took it too seriously", that's why started with "Captain obvious here" implying I know it was meant to be as joke.
Still shared the info since it fits in well with the video.
Gotta give the thumbs up to Parveen on this one. The cap'n is right all around.
You forgot to mention that Ben Brode is laughing hard while copying the script. Lol
Thank you so much. I have been trying to learn about SerializableObjects for a few days now and this is the best thing ever! Clear and concise. Thank you!
I would like to hear about implementing complex skill interaction logic rather than just basics on organizing data members.
I've just watched two videos about Scriptable Objects, including the official 1 hour long Unity video on their website, and they both just hurt my brain. You explained this so well, I'm going to be checking out the rest of your videos for sure. Thanks!
Yeah... Thank you very much for the information. It looks like everyone talking about Scriptable Objects take the "lazy" approach of plugging the reference for the object assets manually directly in the inspector. What about if the card is created at run-time and you don't have the possibility to drag and drop that asset in? Can you reference an Scriptable Object from the assets folder (without using the Resources.Load, since Unity discourages its use)?
Hey Gerardo!
I am just after the same thing, if you can change the object attributes runtime based on user input. Lets say change the artwork based on the user input.
Have you figured it out?
Same thing here. Even with using Resource.Load I can't figure out the correct type for loading the created assets. Resources.Load("xyz.asset"); would come naturally to me, but there is no type Script allowed.
Dude, you honestly helped me so much. For two hours straight I tried to create a scriptable object (using code instead of the unityUI). This is way more convenient.
Great start for 2018! ScriptableObjects are saints sent from Unity heaven!
I use SO's to keep information about weapons, weapon lists, weapon attachments, ammunition, sounds, configuration setups, localization (very basic though), powerups.
But the best thing is I have float variables that I can easily change to change how e.g. a weapon handles its recoil. I highly recommend watching Ryan Hipples Unite Austin 2017 talk (link: ruclips.net/video/raQ3iHhE_Kk/видео.html)!
Yep great for own organization, and even better to allow artists and designers to add and change content themselves while you're busy adding new features or smashing those bugs =)
How do you store and assign values like sounds that would normally be components? Brackeys only shows how to assign child gameObjects, not components :|
You simply declare in your ScriptableObject an AudioSource property for example. Unity will correctly display default components in the editor, and you can even write your own editor override to serialize custom components likeyou wish. But not sure I understand well your problem honestly so sorry if that does not answer your question, feel free to ask again..
Eu Jeen It's simply much faster
Thanks a lot for sharing this Unite talk. * opens scriptable third eye *
Someone give this man a medal.
But how would i make it that each card does something special on the board, like edwin damaging all enemie cards when he is played but tirion destroying a random card
Excellent video, thanks! I had watched the Unity made tutorial on scriptable objects a couple of times and followed that, getting a few pieces I understood. But now after watching your video, I actually understand scriptable objects instead of just getting components working without the needed knowledge to adapt it to my development needs, and your video is like 10x shorter!
thanks M8
I love Scriptable Objects ! I watched a video about those from the Unite Austin 2017 conferences. And it was awesome. Gave me so much idea to work with Scriptable Objects. So now, I'm just waiting for the Unity 2018 releases with C# Jobs, ECS in Scripts and some more stuffs to be fully operational !
Can you please make a tutorial on Easy Save or perhaps make a script or tutorial about how to save your games! By the way,thanks for helping i always support the brackeys team!
Been looking at a lot of camera tutorials for Unity, this is so far the best by far. You explain things well, and the camera mechanics are more advanced and better coded.
Hello, Is there a way to put the ScriptableObject in Array? Instead of manually assigning ScriptableObjects in the screen how about you get a randomizer and those ScriptableObjects in the array and let the randomizer choose?
Did you figure it out?
A classic tutorial from a classic channel in game development.
How would you do to execute different things for each Card?
Make an abstract class of "CardEffect", Give CardEffect an abstract method of ActivateEffect( );
Create all the Effects you want, as sub-classes (extend to CardEffect), then define the ActivateEffect( ) method for each different sub-class
Add the CardEffect class into the Card like he did for cardName, damage, health, and etc, as a variable
Then just drag and drop in whatever CardEffect sub-class you require for your various ScriptableObjects, like he did for the different Sprite images for the card
---
If the above doesn't make sense, lookup how to use abstract classes, and everything will begin to make sense.
@@kserra9112 i know its been 7 months but thank you this helped me a lot
I love Scriptable Objects! It's crazy how this video comes out around the time I'm looking up more info on SO!
Would be cool if he expanded upon this and showed us how to add cards to a deck and then once you purchase the deck with ingame currency or real money you click it and it randomly picks 3 cards based on rng....
Should be easy to figure out. A deck of cards is just going to be a List of cards. Pick 3 cards- just random range between 0 and deck length 3 times, being sure to remove the picked card from the List each draw.
Perfect timing on this for me. I was just looking into scriptable objects the other day and I wasn't sure if I had fully understood them. I definitely do now! I'll be using these for the shop in my current project. Thanks for the great video!
What's the difference between this and making a prefab for each card and changing its values in the prefabs?
Leonardo Gomes he answered your question in the first 16 seconds
prenom nom He didn't really answer it. Why this may cause errors or is incovenient?
The biggest difference is that prefabs also have transform and gameobject data on them which is not needed if the object is only used to store persistent data. ScriptableObjects are created just for that purpose and have alot less overhead.
Also, if you change a scriptable objects parameters during runtime. The changes will be saved and not lost when you exit play mode and that is very helpfull for designers
Haim David Thanks!
Thanks a lot for the explanation!
i don't normally like youtube videos, even if i like them. Brackeys is an exception. Always with quality content. so helpful
Great guide thank you so much, really taught me a lot as a noob to unity, I have 1 question however, at 8:08 you mention that you can easily update these scriptable objects while the game is running, because you are just swapping out simple informaton.
I can see this to be true myself, as I can drag and drop a new scriptable object into the field in the editor while the game is running, and I can see it update instantly. (Using OnValidate() )
My question is, how can I achieve this with script, so that I do not have to drag and drop?
I would like to create a UI button that the user (who does not have editor access) can click, and have the object updated to show a new image. I am sure this is very simple to achieve, but as a total noob I have been having some real trouble finding the proper syntax to write this. I would be very grateful for any help you or anyone reading this can provide, thanks again for the great vid!!
Did you figure this out already?
@@suldra915 Did you in turn figure this out?
Wow, I was just learning about scriptable objects and you made a video about it only 2 years ago! What a coincidence!
can i please use those "aww" sounds at the beginning in a game
I am just finding out about this and am absolutely mind blown. I feel just...enlightened
How do you recreate the mechanics of a boat in Unity? And can you show us a easy way to save things like positions and the progress in the game!
I am not the best in programming, but maybe just saving the Transform of a object in an variable. An progress you can handle, what i can think of:
1. In an rpg you save the complete number of quests in a variable and the number of completed quests also in one an use simple math to calculate the percentage, or
2. you use an array of zones -> you go trough one and the counter for passed zones goes up.
All in all i think it is not that difficult. Bit in terms of the boat i cant help you, im to bad for this
Emil Nilsson There are good tutorials for boats/water online. There are also some free packages you can download and see how they did it
I'd suggest you look into PlayerPrefs in Unity. It's far from elegant, but it's a great & super-simple way to save game progress!
1. Create a plane for the water, trigger collider. 2. Create a boat out of very primitive objects, and add a rigidbody. 3. Write a script, that estimates the how much of the boat's bulk is under the water (in cubic meters), and add force to the boat scaling with the estimated bulk. 4. Adjust rigidbody mass, drag, angular drag and the force you add, and maybe add a little randomized force. Here u have a boat.
I think everyone will be happy to see more tutorials/examples about scripting objects!
But what about unique properties of each card? How would you implement it with scriptableObjects?
László Juhász so, basically you'll still need to create a script for every card that has some unique properties? I thought that maybe scriptableObjects had a better way of handling it but thanks!
Creating a class for each unique card is not recommeneded and will probably won't work well as you add more cards in the future. Instead try to create classes for effects and reuse them on cards (like drawing, dealing damage, healing and so on)
I thought about that already but still, look at the hearthstone, there are so many cards that have unique effects that you can't really reuse
Is it really that many though? yes some cards really do have unique effect that only they can use and no other card can but when you think about it it's only small portion of the cards, most cards are using the same effect and even cards with more than one effect you can just have a queue of effects that will execute in order
+Mikhail Chetverkin You are trying to solve a problem that has nothing to do with ScriptableObjects.
A ScriptableObject holds information that is relevant to its GameObjects implementation behavior. That is it.
What you want the GameObject to do beyond that point (of what is can do within its lifetime) depends on what you give it.
Create all the UniqueProperty sub-classes you need, then...
Give each Card the ability to hold a List and define the call requirements of this
---
Again the ScriptableObject will not only allow you to inject this behavior into the Object at runtime, but also edit the injection of data within the Unity Editor.
It's so fucking cool. I've been trying to investigate what the heck is that before but everything was so messed up, but in this video you made it as clear as possible. THANK YOU MAN
Would it be possible to display the information about the card in the editor as well? Not just when you run the game
MegaMiley (I'm just commenting to get updated on the answer)
Yes there is.
You use Start for when the Game Starts. However you can create a Script that extends from the Editor to Update it when the information changes.
Editor Script ;)
MegaMiley just add "[ExecuteInEditMode]" above your class : docs.unity3d.com/ScriptReference/ExecuteInEditMode.html
Or the "OnValidate" method as I say in an another comment ^^
best scriptable objects tutorial
Can you make save games using ScriptableObjects?
Ok thanks :)
No, you can't. you're not able to modify the data at runtime
To save data I use Binary Formatting.
Here's a quick run through on the MS website: msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.binary.binaryformatter(v=vs.110).aspx
That is not true, you can modify data in SO at runtime and those changes will remain even after you finish the runtime ie. it will override data you filled in the editor.
Is there a way to create saved data for all platforms using a Unity script rather than having to save a different way depending on the platform? Example: Windows 10, PS4, WebGL ...
Now THAT, is how to make a tutorial. Complete from concept/UI to usage at runtime. Brackeys == theBaddestGuyInTown
I don't really understand how these differ from normal Objects.
What do you mean a "normal Object"?, you mean a prefab? Or maybe an Abstract sub-class?
What ScriptableObjects is trying to make simple is a design pattern known as Dependency Injection.
"The goal of the dependency injection technique is to remove this dependency by separating the usage from the creation of the object. This reduces the amount of required boilerplate code and improves flexibility." - Google Search: goal of dependency injection
If you want to use other coding models to achieve your goal, you're welcome to do so, but keep in mind you are using Unity. It makes the most sense to use ScriptableObjects, because it streamlines the development, version control, and overall management of your games data objects.
---
If you still don't get it then I suggest you try to create a game that uses a large amount of items(and create different version of these items). Do it without SerializedObjects, then do a version utilizing this tool. You will quickly understand why Scriptable Objects are essential to anyone working in Unity.
I think what the question is asking here is, in the way that he used this Card class (Object) in this video he could've also just created a class that inherits from nothing that stores primitive values. Stored the actual values like name, etc. In a json file and loaded them at runtime. But the benefit of scriptable objects here is the editor helping do all the setup.
Nicely Done! i love learning from you. you motivate me, I was going to shift to web due to recession in game dev field in my country but i am staying because of you. Because i know game dev is Awesome!!!!
2 + 2 is 4 minus 1 that's 3 quick maths

I said babe, the mans no't' ho't'
Everyday man's on the code, smoke script
See your C in the IDE, that C is a ukers
When a ting went void void void, you man were public
This is overpowered!!! Thank you for gifting us with this beautiful knowledge!!!
Lol, literally every variable he makes is public 🤣
Excellent video, vero pro. I was looking for a good explanation of ScriptableObjects, now it's done. Good job !
To be honest I am a pure rookie/newbie in the gaming field, it happens at times I wanna give up on this you know it's quite overwhelming the amount of info I need to digest to keep up. But thanks to You, Sebastian and other cool guys I can keep Up. You're a great TEACHER. If some days You wanna open a virtual Academy for gaming enlist me
An excellent tutorial. Easy to follow. One of the best explanations I've seen on the topic of scriptable objects. 👍
I just came to say that *this* is the video that explained SO's to me. I am teaching myself unity; I last programmed about 28 years ago, before OOP! heh. Your vid was simple concise and well articulated. Awesome job, thank you.
