Aoediminishingreturns

Based on game build 722832 | Last updated: 2026-04-28

Overview​

Aoediminishingreturns manages diminishing return multipliers for area-of-effect (AOE) damage calculations. It wraps the SourceModifierList utility to track per-source modifiers that combine multiplicatively. This component is typically added to entities that deal AOE damage to prevent stacking exploits from multiple sources.

Usage example​

local inst = CreateEntity()
inst:AddComponent("aoediminishingreturns")

-- Add a modifier from a specific source entity
inst.components.aoediminishingreturns.mult:SetModifier(source_entity, 0.5, "fire_damage")

-- Get the combined multiplier value
local effective_mult = inst.components.aoediminishingreturns.mult:Get()

-- Modifiers are automatically reset when component is removed
inst:RemoveComponent("aoediminishingreturns")
