The Sky Breaker | FORTRESS

ENGINE / RENDERING

Unreal Engine 5.3.2

The third-person action runtime is built with Unreal Engine 5.3.2. The Windows renderer is configured for DirectX 12 and Shader Model 6, with Lumen dynamic global illumination and reflections, plus Virtual Shadow Maps.

GAMEPLAY ARCHITECTURE

C++ · Blueprint · Actor Components

Core gameplay is implemented in C++, while Blueprints connect assets and tune parameters. Cheongryong separates decision-making, flight movement, combat and lightning into Actor Components. UPROPERTY and UFUNCTION expose editable values and callable interfaces; delegates report action stages and completion results.

BOSS ARTIFICIAL INTELLIGENCE

Behavior Tree · Blackboard

Cheongryong's AIController runs an authored Behavior Tree and Blackboard. C++ Tasks, Decorators and Services coordinate attacks and patrols, synchronizing phase and flight state through Blackboard keys. Phase-dependent weights and independent cooldowns govern attack selection, with explicit handling for interruption and external control.

PROCEDURAL ANIMATION

Animation Blueprint · Trail Controllers

Cheongryong's elongated body uses an Animation Blueprint that routes a Local Reference Pose through three Trail Controllers. The body, tail and whiskers follow the head's movement, separating flight control from the skeleton's secondary motion.

COMBAT / TELEGRAPHING

Line Traces · Overlap Queries · Damage

Cheongryong's lightning samples the ground with a line trace and reuses the telegraphed impact coordinates for the strike. Collision volumes and damage handling are separate from presentation, with pending warnings and strikes cleaned up on interruption or death. Fire breath reuses the existing projectile collision and damage path.

VERSION CONTROL

Perforce · Shared Asset Workflow

The team uses Perforce to manage C++ source alongside Unreal assets such as Blueprints, maps and animations. Checkouts and changelists track changes, while personal workspaces and shared assets are kept distinct to reduce conflicts and accidental overwrites of binary assets.

DEVELOPMENT VALIDATION

Unreal Automation · Editor · PIE / SIE

Development Editor builds and Blueprint compilation form the baseline validation workflow. Cheongryong includes C++ Automation Tests for seeded action selection, action lifecycle and circular flight paths. Headless Editor checks and PIE/SIE sessions validate saved-asset loading and runtime behavior in separate steps.
