A source compiler for Blitz3D programs
BLTZNXT

Blitz3D Code,
Compiled Native

Write programs in classic BlitzBASIC syntax. BLTZNXT transpiles your .bb files to C++17 and compiles them to fast native Windows executables using MinGW and SDL3.

Why BLTZNXT?

Everything you need to compile .bb programs

BLTZNXT is a complete Blitz3D compiler pipeline: lexer, parser, C++17 emitter, and a MinGW+SDL3 build step — all in one blitzcc.exe.

Lightning Fast

Compiled to native code for maximum performance. Your games run at blazing speeds with minimal overhead.

Modern BASIC

Clean, intuitive syntax inspired by classic BlitzBASIC but with modern language features and type safety.

Audio Engine

SDL3-powered audio: WAV loading, multi-channel playback, looping, volume/pan/pitch control, music tracks, and 3D positional sound stubs.

Full 2D Graphics

The complete Blitz3D 2D API: window & buffer management, color & drawing primitives, text & TrueType fonts, image loading, animation, pixel buffer access, and collision helpers.

Windows Native

Compiles to standalone Windows executables via MinGW64. Only SDL3.dll is required at runtime — no interpreter, no VM, no overhead.

Open Source

Fully open source on GitHub. Actively developed milestone by milestone. Contributions, bug reports, and feedback are welcome.

Windowed Scaling

BLTZNXT extension: Graphics w, h, 0, 5 opens a resizable window at 2× your logical resolution. Maximise or drag — SDL3 scales the content automatically with letterboxing. Game coordinates never change.

Planned

3D Engine

Full 3D scene graph: mesh loading, textures, brushes, entities, camera, lights, sprites and terrain. The heart of the original Blitz3D experience. Milestones 47–65.

Planned

Collision & Animation

Sphere, box and mesh collision with sliding response, entity picking, keyframe animation and playback control. Milestones 66–70.

Future

Type Methods

Attach functions directly to Type declarations. Call methods on instances with the familiar dot syntax — gentle OOP that stays true to the Blitz3D spirit.

Future

Function Overloading

Define multiple versions of a function with different parameter signatures. The compiler picks the right one automatically — no name mangling visible to the programmer.

Simple & Intuitive

Classic BlitzBASIC syntax that just works

Write familiar .bb programs. BLTZNXT compiles them to native executables — no changes to your existing Blitz3D code needed.
