Define a system goal
State the decision the model should support before adding resources.
About
A free open notebook for learning game development
Eonevolve Learning is a free open notebook for learning game development. Short visual notes on Unity, economy design, feedback loops, and more fields over time. Read one concept today, or follow a path when several pieces belong together.
Fields we write about
These are starting pillars, not a closed catalog. New topics keep landing inside them, and new fields can open as the open book grows.
Game design
Decisions and loops
Feedback, pacing, and the player-facing choices that make a system feel fair and readable.
Unity
Runtime structure
Component boundaries, pooling, and other patterns you can keep small enough to reason about.
Economy design
Sources, sinks, balance
How resources enter, leave, and support a goal without turning into an opaque spreadsheet.
How we create learning material
This notebook is written with a game-designer’s editing eye: protect the player decision, cut what cannot teach, and keep every example easy to reuse on your own project.
Start from a decision
What can a player feel?
We open with a choice, loop, or runtime ownership question. If the reader cannot apply it tonight, the lesson is not ready.
Keep examples portable
Models you can rebuild
Lessons use simple, invented setups so the habit travels. You should be able to redraw the diagram on a whiteboard and try it in your own build.
Review for craft clarity
Publish only what survives a second pass
Game design and Unity craft practice review each lesson for readable cause-and-effect before it ships. Store or platform claims cite public guidance.
How a lesson is shaped
The format stays stable even as the topic list grows: fields, short cards, diagrams, and focused callouts. What you see below is the shape, not the full catalog.
Fields
- Game DesignFrame player decisions, feedback, and readable systems.10 topics
- Unity & DevelopmentBuild clear, maintainable runtime patterns with focused examples.35 topics
- Economy DesignLearn game economy design: connect goals, resources, choices, and feedback loops into systems that hold up under real play.9 topics
Example topic cards
Core loop
Name the repeating intent → action → result → re-entry cycle players must feel.
