This video shows you how to make a simple Ability System for all kinds of games in Unity. The system can be expanded easily and it allows you to change abilities in run time.
Thank you so much this is actually the best video on UA-cam for this exact topic. Been pulling my hair out a few days now within 90% of an rpg alpha and no idea how I was gonna do abilities!!!
Great content, and fantastic format. You show everything, explain it, and you do it quickly while highlighting important things with editing. Great work. Good luck with your future, and thank you for the video!
it makes more sense I think to make the Ability class abstract as you can never have just an, ability and it would allow you to declare abstract method for activate and startCooldown which is cleaner than declaring an empty method implementation and would be overriden the same way; besides that great video ! keep up the good work
I never thought that scriptable object can inherit from base class. This is amazing solution. Before i had ability scriptable objects with 30+ varibles (most of them unused for particular ability). P.S. Im impressed with editing and video quality for your small channel, for sure keep it up.
This is really good way of doing ability system. I am so thankful that this kind of stuff is available for free. I will also create similar system for passive abilities, that don't need activations or cooldowns.
Find das System sehr gelungen und versuche es gerade anzupassen. Hab vorhin "How To Make Your Game Feel Better" reingespült bekommen, auch ein Top Video - man erkennt den Twist in deiner Stimme tho. Ich habe absoluten Respekt für sowohl die Knowledge, deine Englischkenntnisse und dann auch noch die Qualität und das Arrangement deiner Videos. Alles auf den Punkt, kompakt und professioneller als die meisten anderen Tutorials die man so findet. Würde ich als gegeben hinnehmen, guter UA-cam-Kanal eben, aber wenn man dann noch das jung anmutende Alter in Betracht zieht.. ich bin mir selbst ja zu Schade, diesen Kommentar auf englisch zu verfassen.. Hochachtung, danke für die Videos, weiter so :)
If you change a variable value on runtime it stays that way because it is a scriptable object. Having to redo my skill system because I didn't know that. this is a great video
If I want to use a function inherited from the MonoBehaviour class in script DashAblity, do I need to change it to create a variable on the Field to receive a value that is a ScriptableObject?
I figured out how to do everything up to the actual dash ability script with the new input system. Any ideas on how to make the dash ability script work with the new input system? having a lot of trouble
Will there be an error if you remove [CreateAssetMenu] after making the scriptable object? I havent gotten one yet but I want to avoid major errors before hand...
I'm very new to coding and unity in general ,so I know this question might be dumb.So my question is how do I add animations specifically for this type of an ability and does this type of ability apply to making projectiles just with some minor changes to the code?
great video! but how does it work exactly? why would a class that inherits from ScriptableObjects behave like a Monobehavior? (be able to use methods like Update())
I'm very thankful for your video! However, I am having an issue. Whenever I get into my dash ability script, a red squiggle appears under normalized. It says bool does not contain definition for normalized. Is there a way to write this dash ability not using the normalized function? we used a verticalMovement bool using key presses
Thanks! The problem is that you have to convert the bool vertical Movement into a Vector, so you can normalize it. Normalizing is quite important so the dash has the same amount of speed in every direction. I don't know how your code works with a bool as your input but you should be able to turn your input in a vector.
This is an incredible and concise video, it swiftly and correctly explains concepts that many beginning game designers struggle to comprehend. Great job, glad I found the channel.
Thank you! I would create a shield ability by just instantiating (Object.Instatiate) a shield game object where ever you want it to be. And for raycasts the same thing. Just create a raycast and save its hit data as a variable and do what ever you want.
Don't know if you'll ever see this, but how would I go about giving the player multiple swappable abilities? My plan is to make a menu where they can choose their abilities and then hit an apply button that sets their abilities to the ones they selected. Any help is appreciated, thanks.
Awesome tutorial but I’ve been wondering can you visualize the cooldown? And also can you make the ability follow your mouse and not the direction that your character is moving?
Yes, it's possible to visualize the cooldown. The AbilityHolder could have a reference to an UI Slider. On Update the Slider value can be set to cooldownTime / ability.cooldownTime. If the dash should go in direction of the cursor, the ability needs to get movement.directionToMouse(for example) instead of movement.movementInput. Hope that answered your questions :D
Fantastic Video but what if you want to create, lets say, 100 abilities. You will have to create each cooldown/active time for each and everyone, right? Is there a workaround for this issue?
If you are expecting cooldown/active time to be roughly the same for all or most abilities, you can set default values for those variables in the ability script. Or maybe another solution is to keep a static class holding the cooldown/activetime as different constants and have the SO pull the values from that when empty... that way you can group cooldowns into different "default" values instead of being stuck with just one
Just straight up doesn't work for me. I'm doing a platformer so maybe that's why, but when I click the assigned key, it doesn't do anything, even when I turn the velocity up.
Im trying to get this to work with Unity's new third person controller, but the dashability script doesnt seem to be referencing the script for Unitys movement... Any suggestions? also very nice video man im subbed
I sadly can't help with that because I don't know anything about the third person controller. But I hope you find a solution! And thanks for the sub :D
Would you expand it by putting more and more Ability holder on the player or using a list? If using a list, how would you do that? I tried it but it doesnt work for me
Not that it matters anymore, but if you wanted multiple buttons to work for multiple abilities, you could just add other abilities and have them keyed differently. Having the key check in the update is just for simplicity sake. The way I implement multiple abilities is that I can only really use one ability at a time so I just have a UI way to switch them out. Right clicking on a new spell or using a button to bring up a menu where you can click the one you want to use. It will make it so the ability you choose is in the ability variable and therefore uses its functions.
The downside to this system is you are going to make as many CS files as you have abilities... sort of. Any unique ability needs to have a new CS file while any similar abilities but with augments can just adopt those changes. So for instance a dash with y movement could just be setup through the movementInput. I like how simple this system is but it's a bit.
For small games, sure it can be annoying to have these many scripts. But for something bigger, it's better to have separate scripts because what if you eventually decide to have effects unique to your dash? What if there's a very specific particle that is emitted, or some other shader effect made specifically for dashing? Maybe when you dash, you want to have some invincibility frames too. Having abilities decoupled from other systems would be much better for scalability.
While it's great for inspiration, I will rather analyze and design my requirements. The only thing I see reason for a SO is, that you can set it an Icon - visual representation. Otherwise I see a static class, or an xml for data seems better to me. Now thinking....
You probably don't have a movementInput variable or you just typed it incorrectly. The error cs1061 appears when you try to access something like a function or variable that doesn't exist.
Tie it into the animation time if I’m understanding correctly. So instead of ability duration having a hard set amount of time, you could say if my animation is finished then the ability is finished now start cooldown. But if the animation is not finished wait to start cooldown until animation finished.
Do you mean when you write ScriptableObject after the "Ability : "? Probably your Unity project files haven't loaded in correctly. If you are using VS Code, you may have to wait for a bit until your project name is shown in the bottom left corner in VS Code. Then the project files are loaded and VS Code can recognize what you are writing. But if you don't use VS Code or that doesn't work for you, I sadly don't know how to solve the problem.
I would not modify the AbilityHolder but rather add multiple AbilityHolder Components on the same gameobject. But it would be possible to modify the script to manage multiple abilities. If you really want that, you could make a list of abilities, cooldowns and so on. And In the Update function you would have to loop through the hole list and manage all ability specific variables.
@@ThePro-ng4yt That's right, you take the cooldowns/active time from the ScriptableObject and create an Ability[] array and put your ScriptableObjects in there.
If i wanna give my player multiple abilities, do I have to give him multiple AbilityHolder-Scripts or can I somehow combine it in one big AbilityHolder-Script?
@@timberdev thats the way i have done it Right now. One of my skills is shooting a Fire Ball. I am instantiating the Fire Ball throuh script like in your dash script. The Best way to handle its behaviour is through a second script attached to the fireball prefab, Right?
The script can't access the whole player movement script? That's weird. Maybe you are trying to access a private variable in the script. Then you just have to make it public.
if you can skip GetComponent, then it'll be great tutorial, but currently you allow newcomers to learn some bad habits alongside with new practices of scriptable objects
Yeah, it's certainly not the cleanest approach possible but It's not that easy to find a workaround for GetComponent. You could pass a component to the ability instead of just the gameObject. This would avoid the GetComponent part. But the tutorial is mainly about the basic scriptable object ability system. I'm unsure if it is the best way of implementing changable abilities. But for me this is the best way I found. If you have an idea to improve this, please let me know. I would love to learn more :D
@@timberdev usually you know which classes will use abilities and what abilities can potentially use, so you can cache component in ability_user class and make GetComponent func or propety etc. Also, passing "this" instead of gameobject. So ability class can get it by asking user.GetComponent() or kinda like. Even if your abilities can be used by multiple classed, it's better them inherit from same AbilityUser class or IUseAbilities interface which contains functions/properties or kinda like. It's can go very complex, but for this lvl of tutorial it will be enough for AbilityUser script to have public cached component as B&B solution.
I have a feeling this kid lives down the street from Brackeys

Hey, thanks for the tutorial! How would you go about having multiple hotkeys for multiple spells at the same time, using the AbilityHolder script?

Can you please show how to make a damaging ability, like shooting homing missiles when a key is pressed
Thanks to you
But, if more than two entities has the same reference to the ability scriptable, Are both getting the velocity boost?
Good Video
How is it possible that your ball moves at linear speed when in the FixedUpdate of PlayerMovement you are constantly adding to the velocity?

Verdammt gut und Informativ.
Holy Shit. Just clicked on a newer Video and the Voice just flashed me xD
hi! how can Instantiate an object that follow enemy im having problem about "transform does not exits in current context"
I will use this! :D
great video! but how does it work exactly?
why would a class that inherits from ScriptableObjects behave like a Monobehavior? (be able to use methods like Update())
Wow, that switch case with input inside will lead to huge spaghetti code.
Tried setting state to cooldown as default but it always switched to active automaticly, which is so odd
Can you show a show how to make a movement script, your player's movement looks so smooth
I'm very thankful for your video! However, I am having an issue. Whenever I get into my dash ability script, a red squiggle appears under normalized.
