Overview

WCGASDamageResistanceRules is a Data Asset that defines how different damage types are mitigated by armor and resistance attributes. It allows designers to create damage mitigation systems without writing any C++ code, making damage calculation a fully designer-driven workflow. Each rules asset can be configured for different combat contexts (PvE vs PvP) and supports multiple damage types with flexible mitigation formulas.

Creating a Damage Resistance Rules Asset

Using the Wonderscape GAS Ally Menu

1. Open the Content Browser
2. Right-click in any folder where you want to create the asset
3. Navigate to: Wonderscape GAS Ally > Damage > Damage Resistance Rules
4. Give your new asset a descriptive name (e.g., DRR_Default, DRR_PvP, DRR_PvE)
5. Double-click the asset to open it and configure its properties

How Damage Resistance Rules Work

Integration Flow

1. Project Settings Configuration
   • Navigate to: Edit → Project Settings → Plugins → WC GAS Ally
   • Set your Default Damage Resistance Rules asset in the DamageResistanceRules field
   • Optional: Configure context-specific rules in ContextSpecificRules (e.g., PvE, PvP)
   • Set PvPContextTag if using PvP-specific rules
2. Gameplay Effect Setup
   • Create an Instant Gameplay Effect for damage
   • Add Executions section → Set to WCGASExecCalc_DamageResist class
   • Add Gameplay Tags:
     • Required: Damage type tag (e.g., Damage.Type.Fire)
     • Optional: Combat.Context.PvP for PvP-specific rules
   • Configure SetByCaller with tag Data.Damage (or custom prefix from Project Settings)
3. Runtime Mitigation Calculation
   • When damage is applied, the execution calculation:
     • Detects the damage type from the Gameplay Effect's tags
     • Determines combat context (Default/PvE/PvP) based on tags or custom logic
     • Loads the appropriate Damage Resistance Rules asset
     • Queries the target's armor/resistance attribute values
     • Applies armor mitigation formula (if configured)
     • Applies resistance mitigation formula to armor-mitigated damage (if configured)
     • Returns final mitigated damage value
4. Damage Application

   • Blueprint example:

     FGameplayEffectSpecHandle SpecHandle = MakeOutgoingGameplayEffectSpec(DamageEffectClass, 1.0f);

     AssignTagSetByCallerMagnitude(SpecHandle, "Data.Damage", 100.0f);

     ApplyGameplayEffectSpecToTarget(SpecHandle, TargetASC);
