Overview

WCGASAttributeDefinition is a Data Asset that defines gameplay attributes for the Wonderscape Creations GAS Ally plugin. It allows designers to create new attributes without writing any C++ code, making attribute creation a fully designer-driven workflow. Each definition is automatically registered at game startup and mapped to a slot in the WCGASAttributePool (Attribute_00 through Attribute_149).

Creating an Attribute Definition

Using the Wonderscape GAS Ally Menu

Open the Content Browser
Right-click in any folder where you want to create the asset
Navigate to: Wonderscape GAS Ally > Attributes > Attribute Definition
Give your new asset a descriptive name (e.g., DA_Health, DA_Stamina, DA_Mana)
Double-click the asset to open it and configure its properties

How Attribute Definitions Work

Registration Flow

Project Settings Configuration
- Navigate to: Edit → Project Settings → Plugins → WC GAS Ally
- Your Attribute Definition assets are added to the Attribute Definitions array
- By default, bAutoRegisterAttributes = true
Automatic Registration at Game Startup
- The WCGASAttributeRegistry subsystem initializes when the Game Instance starts
- Loads all Attribute Definitions from Project Settings
- Validates each definition (checks for duplicates, missing required fields)
- Assigns each attribute a unique slot (0-149) in the WCGASAttributePool
- Creates lookup maps for fast access by Tag, Name, GUID, or Slot
Runtime Access
- Blueprint/C++ Code: Access attributes via FGameplayTag (e.g., Attribute.Vital.Health)
- Gameplay Effects: Target attributes using their Gameplay Tags
- Execution Calculations: Capture attributes using the registry
- Regeneration System: Automatically applies regen/degen based on definitions
