FW GAS System

Version 1.0 | Category: Gameplay | Loading Phase: PreDefault | Dependencies: GameplayAbilities, ModularGameplay, GameFeatures, EnhancedInput

An integrated Gameplay Ability System framework providing a complete foundation for ability-driven gameplay. FWGASSystem wraps Unreal's GAS with opinionated components for ability granting, input binding, combo systems, ability queuing, modular gameplay actors, and GameFeature actions -- reducing boilerplate and accelerating development.

Key Features

  • Streamlined ASC setup. UFWAbilitySystemComponent auto-grants abilities, attributes, effects, and ability sets from editor-configurable arrays. No manual initialization code required.
  • EnhancedInput binding. UFWAbilityInputBindingComponent bridges GAS ability activation with UE5's Enhanced Input system. Bind abilities to Input Actions with configurable trigger events.
  • Combo system. UFWComboManagerComponent with FWComboWindowNotifyState and FWTriggerComboNotify anim notifies enable montage-driven combo chains with network replication.
  • Ability queuing. UFWAbilityQueueComponent with FWAbilityQueueNotifyState allows players to queue the next ability during an active animation window.
  • Data-driven ability sets. UFWAbilitySet DataAssets bundle abilities, attributes, effects, and owned tags for bulk granting and removal with handle-based lifecycle management.
  • Modular gameplay actors. Pre-built base classes (AFWModularCharacter, AFWModularPlayerState, etc.) with IGameFrameworkInitStateInterface support for modular game feature integration.
  • GameFeature actions. UFWGameFeatureAction_AddAbilities, UFWGameFeatureAction_AddAnimLayers, UFWGameFeatureAction_AddInputMappingContext for clean feature-driven content injection.
  • Core component abstraction. UFWGASCoreComponent provides a unified event surface for attribute changes, ability lifecycle, effect tracking, cooldowns, and death -- abstracting away ASC owner/avatar complexity.
  • Built-in attribute set. UFWAttributeSet ships with Health, Stamina, Mana (each with Max and RegenRate), plus Damage and StaminaDamage meta attributes.
  • Effect containers. FFWGameplayEffectContainer and FFWGameplayEffectContainerSpec simplify targeting and effect application patterns.
