Hyperblood Overdrive Engine Features

Core Architecture

Base Framework:

• Built atop GZDoom 4.x core for modern compatibility and UDMF map format.

• Incorporates a Build-like sector/voxel handler adapted from EDuke32’s sector system, allowing full 2.5D editing freedom with room-over-room and destructible geometry.

Scripting Languages:

• ZScript and CON hybrid system — allows importing of both .CON (from Build) and .ZSC (from GZDoom) to support mixed modding workflows.

• New HBScript (Hyperblood Script): a meta-layer that lets you write logic in CON-style syntax but compiles to ZScript internally.

🏗️ Rendering & Level Geometry

True Room-Over-Room (TROR)

• Full stacked sector and transparent portal rendering, backported from EDuke32.

• Allows vertical overlapping rooms, layered maps, and elevators — all compatible with GZDoom lighting and 3D floors.

Build ART Format Support

• Native loading of .ART tilesets for textures and sprites.

• ARTs are automatically converted to GZDoom material definitions (TEXTURES lumps) at runtime.

Dark Forces WAX Support

• Supports .WAX animated sprites from Dark Forces, allowing custom sprite-based actors with frame scripting and hitbox data.

• Optional conversion to MD3 or voxel entities for modern rendering.

🧱 Object & Actor System

Voxel and Model Hybrid System:

• .KVX, .VOX, .MD3, and .OBJ models supported simultaneously.

• Custom shading styles: “RetroFlat”, “BuildSmooth”, and “ModernPhong”.

Destructible Environments:

• Build-like wall and sprite destruction with physics fragments.

• Integrated debris management system for performance-friendly gibbing.

🔫 Combat & Physics Layer

HitScan+Projectile Fusion:

• Projectiles simulate Build’s “fast ray with sprite body” and GZDoom’s accurate physics.

• Dual system allows both retro instant hits and modern ballistic modes.

Dynamic Limb Damage:

• Based on ZScript’s actor damage states but expanded to include Build-like limb gibs (separate body parts, similar to Blood/Shadow Warrior).

🌆 Environmental Systems

Lighting & Effects:

• Combines GZDoom’s dynamic lighting with EDuke32’s sector lighting logic (shade tables).

• Real-time reflections and animated texture warping.

Liquid and Sky Layers:

• Multi-depth water using TROR — swimmable with reflection layers.

• Parallax skyboxes with optional Build-style tile skies.

🎵 Audio & Interactivity

Audio Engine:

• MIDI, OGG, and tracker (MOD/XM/S3M) support.

• Environmental reverb zones (Build’s reverb sector effect recreated).

Interactivity:

• Classic Build-style usable objects (switches, doors, cameras).

• Advanced GZDoom ACS triggers, now callable via .CON functions.
