Overview

Third-person ability system prototype built in Unreal Engine — focused on C++ gameplay systems architecture and Blueprint integration.

How to evaluate (40 seconds)

• Press 1 → single projectile fires, hits golem, health bar drops
• Press 1 again immediately → slot dims, cooldown visible in HUD
• Press 2 → burst fires 3 projectiles in a spread pattern
• Press 1 then 2 quickly → both cooldowns run independently
• Focus fire on one golem → health depletes, golem disappears

What this demonstrates

• Ability system: UObject instancing per slot, per-slot independent cooldowns, Blueprint-tunable via subclassing
• Interface-based damage: IDamageable UINTERFACE — projectile has no dependency on any specific enemy class
• Event-driven HUD: FOnSlotChanged delegate drives slot updates — component has no knowledge of the HUD
• Projectile abilities: two distinct behaviors (single + burst) sharing the same projectile base class

Controls

• Move: WASD
• Look: Mouse
• Slot 0 (Single Projectile): 1
• Slot 1 (Burst): 2
• Quit: Escape
