UAttributeSet::PostAttributeChange

function GameplayAbilities Since unknown

#include "AttributeSet.h"

Access: public Specifiers: virtual

Description

Called just after any modification has changed an attribute's current value. Use this to react to the new value, for example broadcasting a UI update or checking for death when Health hits zero.

Caveats & Gotchas

• By the time this runs the change is already applied; you can't cancel or clamp it here, only respond (use PreAttributeChange for clamping).
• Fires for every attribute on the set, so most overrides start by checking Attribute == GetXAttribute() before acting.
