Simple Gravity Example — Blitz3d Code

Applies gravity to a cube.

Graphics3D 800,600
cube = CreateCube()
PositionEntity cube,0,10,0
ySpeed = 0
gravity = 0.01

While Not KeyDown(1)
	ySpeed = ySpeed + gravity
	MoveEntity cube,0,ySpeed,0
	If EntityY(cube) > 0 Then
		PositionEntity cube,0,0,0
		ySpeed = 0
	End If
	RenderWorld

Blitz3d Language Guide

Blitz3D is a legacy, beginner-friendly programming language and IDE for 2D and 3D game development, using a BASIC-style syntax with built-in graphics, sound, and input handling.

Primary Use Cases

▸2D and 3D PC games
▸Educational programming exercises
▸Prototyping game mechanics quickly
▸Interactive demos and simulations
▸Hobbyist and indie game projects

Notable Features

▸BASIC-style syntax for ease of use
▸Built-in 2D and 3D graphics support
▸Integrated sound and music handling
▸Simple input handling for keyboard, mouse, and joystick
▸Rapid compilation to native Windows executables

Origin & Creator

Blitz3D was created by Mark Sibly in 2001 as part of the Blitz Research series of programming languages.

Industrial Note

Blitz3D is notable for rapid prototyping of 2D/3D games with minimal setup, though it has largely been superseded by modern engines.

Quick Explain

▸Blitz3D uses a simple, BASIC-like syntax making it approachable for beginners.
▸It provides built-in support for 2D/3D graphics, physics, audio, and input without external libraries.
▸Used historically by hobbyists, indie developers, and educational projects for games and visual simulations.

Core Features

▸2D graphics: sprites, blitting, image manipulation
▸3D graphics: meshes, textures, cameras, lighting
▸Physics: basic collision detection and movement
▸Sound and music playback via built-in functions
▸Window management and input events

Learning Path

▸Learn BASIC syntax
▸Understand 2D graphics and sprite handling
▸Study 3D coordinate systems and meshes
▸Implement simple game logic and loops
▸Deploy small projects on Windows

Practical Examples

▸2D platformer
▸Top-down shooter
▸3D racing or maze game
▸Physics-based puzzles
▸Interactive visual demo

Comparisons

▸Blitz3D vs Unity: simpler, code-only vs editor-based full engine
▸Blitz3D vs Godot: legacy vs modern multi-platform
▸Blitz3D vs Unreal: lightweight BASIC vs AAA engine
▸Blitz3D vs GameMaker: more code-focused vs drag-and-drop IDE
▸Blitz3D vs Love2D: similar simplicity, but Blitz3D has 3D support

Strengths

▸Easy to learn for beginners
▸Fast development and compilation
▸Integrated all-in-one environment
▸Good for learning programming and 3D concepts
▸Active sample projects and tutorials historically

Limitations

▸Windows-only executable output
▸No longer actively maintained
▸Limited 3D engine capabilities compared to modern engines
▸Lacks advanced networking and modern graphics features
▸Small community and outdated documentation

When NOT to Use

▸Modern cross-platform development
▸AAA-quality graphics
▸Mobile or web deployment
▸Complex networking or physics
▸Team-based large-scale projects

Cheat Sheet

▸Graphics3D = initialize 3D mode
▸LoadImage = 2D sprite
▸LoadMesh = 3D model
▸PlaySound = audio playback
▸UpdateWorld = render/update loop

FAQ

▸Is Blitz3D free?
▸Yes, freeware for Windows.
▸Does it support 3D?
▸Yes, basic 3D graphics supported.
▸Which platforms are supported?
▸Windows only.
▸Is it beginner-friendly?
▸Yes, especially for those learning game programming.
▸Does it have modern community support?
▸Limited; mostly archived resources and hobbyist communities.

30-Day Skill Plan

▸Week 1: Basic syntax and 2D graphics
▸Week 2: Input handling and events

▸Week 4: Audio integration and physics
▸Week 5: Small complete game project

Final Summary

▸Blitz3D is a beginner-friendly BASIC-style language and IDE for 2D/3D games.
▸It provides integrated graphics, audio, and input support for Windows.
▸Best for hobbyists, indie developers, and educational purposes.
▸Allows rapid prototyping but lacks modern engine features.
▸Not suitable for mobile, web, or large-scale commercial projects.

Project Structure

▸Main.brs - main program file
▸Images/ - 2D sprites and textures
▸Meshes/ - 3D model files
▸Sounds/ - audio files
