STEALTH COMBAT PROTOTYPE

A stealth-combat game prototype, where you sneak around to kill enemies, and if they spot you, you can run away and hide or try to fight them head on.

By building on top of Unreal's Perception System, I implemented distance and space-based detection using C++, so the enemies have different thresholds with which they detect you quicker.

Built in Unreal Engine 5 C++ using Gameplay Ability System (GAS)

Made for Florida Interactive Entertainment Academy

Tech Design 3 Final Project

The sounds detected by the enemies set an increase in the Awareness Meter instantly, while the Sight detection gradually increments it.

Both of them use a dynamic percentage based threshold.

Player Detection Behavior

Inside the Tick function, set the Awareness amount based on the Gain Rate or Decay Rate, as well as if they have a line of sight or are being alerted by the Coward enemy.

The game uses a hybrid of Behavior Trees and Finite State Machines, where the decorators dictate the branches that the enemies can access, each one representing a different state.
