A simple project for learning Gameplay Ability System. Everything is implemented with C++ only. There is only a small amount of functionalities happening in this sample. This is the bare minimum of what GAS supports:
- A AbilitySystemComponent is granted with a GameplayAbility through GiveAbility, which effectively returns a handle to the ability granted.
- A AbilitySystemComponent issues an ability through TryActivateAbility with the handle it retains.
- ActivateAbility function from the GameplayAbility is triggered. This issues an AbilityTask to play montage.
- The AbilityTask starts the montage and subscribes to the callback when an event with specific GameplayTags is sent to the AbilitySystemComponent.
- An AnimNotify sends the above event to the AbilitySystemComponent, which gets propogated to the callback the AbilityTask provides.
- Through the callback above, the GameplayAbility can then apply some GameplayEffect through ApplyGameplayEffectSpecToTarget. Simultaneously, some GameplayCues could be triggered through K2_ExecuteGameplayCueWithParams.
- The GameplayEffect applied from the previous step invokes GameplayEffectExecutionCalculation to run the effect calculation logic.
- Eventually, AttributeSet applies the actual effect using the results calculated above. This happens inside PostGameplayEffectExecute
