Tank Battle — Multi-Enemy AI System

A third-person tank shooter built entirely in Unreal Engine 5 C++, featuring multi-enemy AI with NavMesh pathfinding, spatial audio, particle FX, a full health/damage system, and custom respawn logic.

Overview

Tank Battle is a fully C++-driven 3rd-person shooter that demonstrates core gameplay programming skills: AI enemies that pursue and attack the player, a damage/health model, particle and audio feedback, and a respawn system — all without relying on Blueprint logic for the core systems.

AI System

Enemy tanks use UE5's NavMesh system for pathfinding and a simple behavior tree-style logic to switch between patrol, chase, and attack states. Each enemy detects the player via line-of-sight checks and adjusts its movement speed and targeting accordingly.

NavMesh-based movement with dynamic obstacle avoidance
State machine: Idle → Patrol → Chase → Attack
Line-of-sight detection using UE5 ray casts
Multiple simultaneous enemies with independent AI instances

Core Systems Built

Custom C++ health and damage component — modular and reusable across actors
Projectile system with collision detection and impact force
Spatial audio — volume and panning tied to enemy distance and direction
Particle FX on hit, explosion on death
Respawn system with configurable delay and spawn point selection
Custom player input controller using UE5 Enhanced Input

What I Learned

This project deepened my understanding of UE5's component architecture and how to structure large gameplay systems cleanly in C++. Separating health, damage, and movement into reusable components made iteration much faster and the codebase easier to reason about.
