Spire Systems Ability Cooldown System is a Blueprint-only ability-use foundation for Unreal Engine 5.8.

Add reusable ability cooldowns, charges, resource costs, resource restoration, global cooldown behavior, availability states, and HUD feedback without building a larger ability framework from scratch.

Ability activation is centralized through a unified TryUseAbility flow. The included demo supports keyboard activation and clickable HUD ability buttons while demonstrating cooldown timing, charge consumption and refill, resource use, Ready / On CD feedback, personal and global cooldown states, and unavailable-charge dimming.

The system also demonstrates cooldown interaction behavior, including PowerSurge resetting Dash and Heal reducing Shield cooldown.

An OnAbilityUsed event and confirmed bridge data provide optional integration with Spire Systems Status Effect System Lite. Neither product requires the other.

Ability Cooldown System is intentionally focused on ability availability and cooldown management. It does not provide a complete combat system, projectile framework, RPG skill tree, inventory, save/load system, multiplayer ability framework, stat system, Gameplay Ability System replacement, automatic status-effect processing, health feedback, or death/respawn system.
