Before We Start What You Need A text editor (VS Code, Notepad, or any code editor) A web browser (Chrome, Firefox, Edge) Limn Engine — download epic.js from limn-engine-doc.vercel.app What You Should Know Basic JavaScript (variables, functions, arrays, if-statements) How to open an HTML file in a browser No game development experience required! Step 1: The HTML Structure Every Limn Engine game starts with a simple HTML file. <!doctype html> <html> <head> <script src= "asset/epic.js" ></script> </head> <body> <script> // All your game code goes here </script> </body> </html> What's happening: <script src="asset/epic.js"> — loads the Limn Engine library Everything inside the second <script> tag is your game code Save this as game.html and open it in your browser. You should see a blank canvas with a blue gradient background. Step 2: Setting Up the Game The first thing we need is a Display — this is the engine that creates the canvas, runs the game loop, and handles input. const display = new Display (); display . perform (); // Activates performance mode (dual-canvas rendering) display . start ( 800 , 600 ); // Creates an 800×600 canvas What's happening: new Display() — creates the engine display.perform() — turns on high-performance mode display.start(800, 600) — creates a canvas 800 pixels wide and 600 p
