Call
Runs a snippet. The name is the file name.
Call:[GrassPlain]PYROGON™
Forge worlds with fire.
Make games in a few lines of code.
The language
Scroll to write
a 3D game.
Now change your mind. One line re-lights the whole world. A mod changes the call above it without touching the snippet, and you can stack them.

Your game
A window, or the browser
Pyrogon compiles to Python, so it works with Python, not against it. A snippet can always drop down into plain Python when it needs to.
The whole language
Everything you need
fits on one page.
Mod
Changes the call it is indented under. Stack as many as you like.

Mod:[Glowing]Good to know
- Lines run top to bottom. Call a style first, then a canvas, then what goes on it.
- All 3D calls build one 3D scene. It opens in the browser when the program ends, and needs internet each time.
- All 2D calls share one canvas window. Close it or press Esc to stop.
- To make your own call, copy a snippet and rename the file. The file name is what you Call.
- A .bat needs Python and Pyrogon on the PC, so it is for playing on this PC.
What's in the box
Say what you want.
The engines do the work.
3D engine
Physically based sky, clouds, sun rays, bloom, ambient occlusion and colour grading. Call:[UltraGraphics] turns it all the way up to hyper.
2D engine
One shared canvas and game pieces that work together: a Player, Coins, FallingRocks, a ScoreBoard, title cards and countdowns.
The shapes
Real 3D models, made for you. Whole oaks and boulders drop straight into your game with one Call, and more are on the way.
The surfaces
Bark, brick, rock and more in razor-sharp 4K, ready in as little as 10 seconds.
Scenes and gates
More than one place in a game. Walk through a Gate and the world fades into the next scene. Score and lives come along.
Music and voices
One line plays a song, a playlist or a voice line. The music ducks while someone talks, and the words show on screen.
Your own version
Type empty brackets and the IDE fills in a call's real settings. Change them, press Run, and it becomes your own snippet.
One file to play
Pack the finished game into a single .bat. Double-click it and it plays, with no IDE and no Run button.
Pyrogon AI
An AI that writes
your game for you.
A personal coding assistant with its own name and personality. Say what you want in plain words and it writes the whole game. It speaks Python and other languages too.
- Creator mode. It builds a first version, then keeps testing and improving it, round after round, until you click Wrap up.
- Runs its own code. It tests what it writes, and asks you first.
- Searches the web when it needs fresh information.
- A perfect score. 18 out of 18 game requests it had never seen, built right. And 88.4% on the HumanEval Python test.
- No graphics card needed, soon. Pyrogon AI is moving off your GPU, so you will not need a gaming PC to use it.
