Learn CATSCRIPT with Real Code Examples

Updated Nov 27, 2025

Explain

CatScript is beginner-friendly and designed to be easy to read and write.

Supports variables, functions, loops, and events.

Optimized for animations, simple games, and interactive applications.

Runs in lightweight interpreters or browser environments.

Encourages creative exploration and rapid prototyping.

Core Features

Variables and basic data types

Functions and parameters

Loops and conditionals

Event listeners (e.g., mouse, keyboard)

Basic graphics primitives (draw, move, animate)

Basic Concepts Overview

Variables - store data

Functions - reusable code blocks

Events - respond to user input or timers

Loops - repeat tasks

Drawing - create visual output

Project Structure

main.catscript - entry script

modules/ - reusable function libraries

assets/ - images, sounds, animations

examples/ - sample scripts

README.md - documentation

Building Workflow

Write CatScript file (.catscript)

Use functions and loops for logic

Add event listeners for interactivity

Test in runtime or browser

Iterate based on visual feedback

Difficulty Use Cases

Beginner: print statements, variable manipulation

Intermediate: simple animations and loops

Advanced: interactive games and event handling

Expert: modular scripts and creative storytelling

Architect: educational workshop or curriculum scripts

Comparisons

CatScript vs Python: CatScript simpler, more playful, browser-friendly

CatScript vs Scratch: CatScript textual vs Scratch block-based

CatScript vs JavaScript: CatScript beginner-focused, lightweight

CatScript vs Lua: Lua general-purpose; CatScript educational

CatScript vs Processing: Processing more powerful graphics; CatScript simpler
