Common Ability Set

What is Ability Set?

Gameplay Ability Sets allow you define a set of abilities and effects which are given to the target ASC, I use these to apply the default generic abilities a player has, and default generic effects each player will have. These can also be used for things like perks, etc. The other benefit is, they can be added and removed via a simple handle.

How does Common GAS apply the ability set?

In Common GAS, the method of granting this ability set to player-controlled character is adding this in their ACharacters->ACommonModularCharacter blueprint character class CDO under CommonGAS->Character->Abilities->AbilitySets

In c++, you can get a reference to UCommonAbilitySet and calling GiveToAbilitySystem() where you need to give it a valid UAbilitySystemComponent reference so it can add it to

UPROPERTY(ReplicatedUsing=OnRep_ActivateAbilities, BlueprintReadOnly, Category = "Abilities")
FGameplayAbilitySpecContainer ActivatableAbilities;

for Default Character Abilities, Default Gameplay Effects will be added to FActiveGameplayEffectHandle and Default Attribute Set will be added using AbilitySystemComponent's AddAttributeSetSubobject()
