In plain English

Island Mystery Game is a 3D browser-based game where you wake up on an island and just... explore. There's no mission to save the world or defeat a boss. The goal is simply to enjoy the island: pick up branches to start a fire, throw rocks, climb a mountain, and listen to nature sounds. It was built as a final project for a computer graphics course at UCLA in 2014. You move around a first-person 3D world rendered in your browser using JavaScript. The island has four regions, hills, forest, bay, and mountain, and the terrain is partially randomly generated each time, so no two playthroughs look exactly the same. Trees and objects are scattered around procedurally too. You can pick up sticks and stones, jump, throw rocks (which bounce off trees realistically), and build a campfire at the firepit, which then lights up the surrounding rocks. There's a day-night cycle with spooky music at night. This is a student project, so the audience is really anyone curious about what a small team can build in a graphics class. It's less a polished game and more a tech demo showing off collision detection, simple physics, lighting, and bump mapping (a technique that adds surface texture detail to 3D objects). The README credits five students who each took on different pieces, one handled collisions, another did physics and movement, another built the terrain and sound, and so on. To play it, you need to run a simple local web server from the project folder and open it in your browser. The creators note it works best on Firefox, should work on Chrome, and is untested on Safari. There's also a live demo linked from the README if you just want to try it without setting anything up.

Copy-paste prompts

Prompt 1
Help me set up a local web server to run Island Mystery Game in my browser, I've cloned the repo and want to play it on Firefox
Prompt 2
I want to understand how the procedural terrain generation works in this 3D island game so I can tweak the island shape and tree placement. Walk me through the relevant code
Prompt 3
Add a new interactive object to this island exploration game, something the player can pick up and use, following the same patterns as the stick and stone mechanics
Prompt 4
Explain how the campfire lighting effect works in this game and help me make the fire glow brighter and affect a larger area around the firepit
Prompt 5
I want to port this 2014 WebGL island game to run smoothly on modern Chrome. What changes should I make to the rendering and physics code?
