Play Dark Forest

Dark Forest is a JavaScript browser game inspired by Katamari Damacy and Cixin Liu's Remembrance of Earth's past Trilogy. The player controls an advanced alien weapon and must destroy the planets in the correct order.

Dark Forest is built with Canvas animation library Paper.js. However, instead of using that library's PaperScript syntax, Dark Forest is implemented in straight ES6, bundled up with Webpack. The bundler also compiles serves the game's SASS styles, which are responsible for the game's background and menu animations.

Planetary velocities are calculated through a simplification of orbital physics:

Velocity = Sqrt(StellarMass/OrbitalRadius)

• Weapon: Renders the player, contains logic for moving player in response to user input and increasing player size when a planet is consumed.
• Star: Renders the solar system's star, with a random mass between 35 and 85, and one of five colors. Also handles pulsing animation for star.
• Planet : Renders a planet based on a planetSeed object, which contains it's mass oribtalRadius, and one of 14 sprite types. Handles orbit.
• System : Calls the render of Planets from a randomized set of seeds and the mass of the system's Star. All Planets are kept in an array as an attribute of the System class, to simplify hit testing and calling the orbit functions for each planet.

• paper : All visible game elements are called on this class from Paper.js. Animations and hit testing are all called through its onFrame method.
• Game : Initializes the paper object on the #game Canvas element and renders initial game objects, before setting up onFrame.
• collisionCheck : Checks if the weapon is in the same space as a planet.
• isOver : Checks if either end state condition has been reached and displays appropriate menu.
