Overview

WCGASAbsorptionData is a Data Asset that defines absorption rules for the Wonderscape Creations GAS Ally plugin. It allows designers to configure how actors convert blocked effects into counter-effects without writing any C++ code, enabling fully designer-driven absorption mechanics. When an actor with immunity blocks an incoming GameplayEffect, the absorption system checks these rules to potentially apply a beneficial counter-effect.

Creating an Absorption Data Asset

Using the Editor

1. Open the Content Browser
2. Right-click in any folder where you want to create the asset
3. Navigate to: Miscellaneous > Data Asset
4. Select WCGASAbsorptionData from the class picker
5. Give your new asset a descriptive name (e.g., DA_FireDemonAbsorption, DA_IceElementalAbsorption, DA_VampireAbsorption)
6. Double-click the asset to open it and configure its properties

Registration Flow

1. Component Configuration
   • Add WCGASResistanceComponent to your actor
   • Assign your Absorption Data asset to the AbsorptionData property
2. Automatic Binding at Initialization
   • When the Resistance Component initializes, it checks for absorption rules
   • If rules exist, it binds to the ASC's OnImmunityBlockGameplayEffectDelegate
   • This delegate fires whenever an effect is blocked due to immunity
3. Runtime Processing
   • When immunity blocks an effect, the callback evaluates absorption rules
   • Hierarchical tag matching finds the best rule for the blocked effect
   • The absorption effect is looked up via StatusEffectSubsystem::GetEffectClassByTag()
   • Magnitude is extracted, multiplied, and applied via SetByCaller
