[UE5] Learn Unreal Engine's GAS in 14.65 minutes 🤓

Hey there! Here's a quick guide covering everything you need to know to get started with Unreal Engine's Gameplay Ability System (GAS).
I know my first few videos are rough (I was still learning Unreal/GAS), so to make it up to you all, I decided to condense them into a short, effective tutorial that covers the core concepts under 15 minutes.
I put a lot of effort into organizing the content as well as editing the video, so I hope you all find this helpful!
I'm currently working on a rogue-like tower-defense game that makes heavy use of GAS, so if ya'll are interested, I might make a devlog to cover some of the systems and abilities I built for it.

I highly recomend to watch this video since it is very well explained in a step by step manner. I have watched a lot of other tutorials in this subject but I learned only from this one.

Keep it up! This is the greatest example video of GAS on the youtube! I can say that, because I watched almost all of them unfortunetly... You are giving great example cases in a simplied enviroment which is the best way to teach anything. I hope you cover all the over overlooked aspects of the GAS!

"Target Tags Gameplay Effect Component" is now "Grant Tags to Target Actor"

This is pretty great, you condensed a lot of information in just a short while. A lot better than some of the other videos on GAS out there that take a thousand years to cover only a tiny slice of info on it.

In 5.4.1 the BP_FirstPersonCharacter no longer has a weapon variable. It also seems "Target Tags Gameplay Effect Component" has been renamed to "Grant Tags to Target Actor". I'm a newb so could be wrong but a simple fix for the first problem seems to be instead when building the GA_ShootRifle class, use a "Get Component by Class (BP_Weapon_Component)" which you can then get the projectile offset off of. Thanks much for the video!

Very good content! I would like to see how to deal with more complex effects, such as asynchronous effects or effects that perform a function at the start and end of the targets. Example An ability that creates a projectile, which, when hit, applies a slow effect for X seconds and after completion, creates an explosion in the area that leaves enemies stunned. Example 2 An item that cancel slow or stun effects, or reduce % of negative effects

Great Video! Although I wonder if it would be better to use an Interface or GameplayTags instead when Casting or the GetAbilitySystemComponent node is used? 🤔

@sami444L Ай бұрын

Underrated

@pimeine Ай бұрын

Very nice! I have a question remaining, if we want to activate an ability by tag for a primary weapon but have multiple weapons using this same tag, how should we differentiate them? With multiple unique tag based on weapons or is there a short cut? Thank you!

At 5:20, can you have gameplay effects that last for a set number of turns? or is it always a float value of seconds?

@henrybottomsworth Ай бұрын

i cant get the attribute to show up in the drop down list when trying to add a modifier to my gameplay effect. help! nevermind, you have to put this in the uproperty, "Meta = (AllowPrivateAccess = true)" also if you are not using the FPS template you should watch Umbral Studio video on how to make your own enhanced input Input Mapping Context and Input Actions.

How is it in replication terms? Do i still need to use Events such as Run on Server, Multicast etc? So whats the workflow for a full proper multiplayer game? Im not sure if i need it tbh, i was doing it the old fashioned way.

If the Target Actor has the DefaultSceneRoot as its root component instead of the StaticMesh component, the 'Auto Attach to Owner' toggle on the GameplayCue doesn't work. I am on 5.4.

@noname_2108 Ай бұрын

This is actually logical as you don’t move the root when applying rigid body physics to static mesh. I’m sure you can attach the effect manually by overriding some gameplaycues functions.

Awesome tutorial!! I was wondering, if I wanted the Dummy cube to die when it hits 0 HP, what would be the best way of doing that? Obviously I can check every Tick if Get Gameplay Attribute Value is

@umbral_studios 9 күн бұрын

Yes! You can bind an "on change" function to an attribute like this: AbilitySystemComponent->GetGameplayAttributeValueChangeDelegate(AttributeSet->GetHealthAttribute()).AddUObject( this, &YOURCLASS::OnHealthChangedInternal ); where: - OnHealthChangedInternal is defined as void OnHealthChangedInternal(const FOnAttributeChangeData& Data); - AttributeSet is defined by doing auto AttributeSet = AbilitySystemComponent->GetSet();

@notsospy 9 күн бұрын

@@umbral_studios Wow, thanks for the quick reply!! that's interesting! Actually, I was reading up on PostGameplayEffectExecute which might also be useful for this - basically after a gameplay effect triggers a value change, I can check whether the new value is

@notsospy 9 күн бұрын

On second thought, I can probably just define a BlueprintNative function in C++ and implement it in BP like this - UFUNCTION(BlueprintNativeEvent, BlueprintCallable) void OnDeath();

@notsospy 9 күн бұрын

@@umbral_studios Okay so I was able to solve this rather simply! I created a `BaseActor` class which just implements UFUNCTION(BlueprintNativeEvent, BlueprintCallable) void OnDeath(); and set my Dummy cube base class to BaseActor. I then override OnDeath in the Dummy cube BP and do whatever I want to happen when the cube reaches 0 HP (for testing - print string and destroy actor) Then in PostGameplayEffectExecute I check whether health is OnDeath(); } This is just for testing purposes of course, the code is pretty 👎For one I would probably create a IKillable interface instead of a base class, so that it doesn't matter what I attach it to (Actor, Pawn, Character, etc.) But anyways - it works great! And I can do most of the actual logic in BP!

hold on a second, I thought to enable GAS you had to go through some C++ compiling. DId Epic actually made it native in blueprint at some point? no documentation as usual from them. EDIT: actually nevermind, there's still C++ compiling you do afterward, still a good video
