Setting & Querying Cooldowns

C++ 
HotbarComponent->SetSlotCooldown(SlotIndex, CooldownDuration);

float Remaining = HotbarComponent->GetSlotCooldownRemaining(SlotIndex);
float Total     = HotbarComponent->GetSlotCooldownTime(SlotIndex);

float Progress = (Total > 0.f)
    ? 1.0f - (Remaining / Total)
    : 1.0f;
Blueprint Nodes:
  • Set Slot Cooldown
  • Get Slot Cooldown Remaining
  • Get Slot Cooldown Time
You can convert these to a 0–1 progress value and drive a radial or bar overlay in your UI.

Enabling Cooldown Ticking

Call once (BP or C++):
  • Blueprint: Start Cooldown Ticking
  • C++: HotbarComponent->StartCooldownTicking();
