Branch remarks

this branch contains updates to the original course code for Godot 4. The scripts will be annotated regardings changes like tihs:

# Camera zoom logic seems to be reversed between Godot 3 and 4, bigger numbers are now more zoomed in

I plan to update the scripts and remove these comments for future reference, when Godot 4 is standard and changes over Godot 3 are no longer relevant and comments about it amount to noise. Also the current effort is change as little as neccessary. Only later it will be about adapting to Godot 4 best practises.

Godot Procedural Generation

Godot PCG (Procedural Content Generation) is a project to build a series of algorithms and demos to learn about procedural generation. The algorithms are from our course Godot PCG Secrets.

Available demos

RandomWalker

This is an algorithm as seen in Spelunky. This algorithm uses a node that walks randomly on a grid, places hand-designed level chunks, and randomizes them to generate unique levels.

WorldMap

This project demonstrates a technique for generating a world map with biomes and rivers, heavily relying on shaders. It's inspired by Procedurally Generated Wrapping World Maps in Unity C# although it uses a completely different implementation.

BasicDungeonGenerator

A basic generator to get started with procedural content generation. Creates rectangular rooms, rooms with organic shapes, and corridors connecting the rooms.

ModularWeapons

Procedural or emergent gameplay system where you can stack movement modifiers and different emitters to generate weapons. A game that references techniques like this are Binding of Isaac or Enter the Gungeon.

Infinite worlds

In SpaceInfiniteGeneration/, you'll find four infinite world generation demos. You can travel infinitely with your ship, the world never ends. The first two demos generates worlds full asteroids using white noise and blue noise, respectively.

The LayeredWorldGenerator scene shows how to use layered generation to create a universe with planets, moons, trade lanes, and asteroid belts.

Finally, the PersistentWorldGenerator builds upon the previous demo and adds the ability to make persistent changes to this infinite universe.

How to use

Clone the repository and import the godot/ directory as a Godot project. Each demo is in a separate sub-directory.

The start-project/ directory contains starters for students of our course Godot PCG Secrets and not the complete demos.

In the demos, where relevant, we use a timer to show you the content generation steps, as the final level would otherwise appear instantly. Doing so helps to visualize and debug algorithms. Remove that timer code for the algorithm to run at full speed.
