Nabla Operator Game ナブラ演算子ゲーム

This project is a web version of the physical card game created by UTokyo students here: https://nablagame.com/.

The live version of the game is available here: https://nabla-game.netlify.app.

The source code is written is Rust + WASM, bootstrapped from here: https://github.com/rustwasm/rust-webpack-template.

Additionally, the math engine implements a custom Computer Algebra System (CAS) to calculate arbitrary Derivatives and Integrals, in additional to other algebraic functions such as Mult, Div, Sqrt, Log, etc.

Packages used:

• KaTeX for LaTeX typesetting
• web-sys for js DOM structs in Rust
• wasm-bindgen for Rust ↔ js ABI communication and build tools
• gloo for better js Event Listener ABIs in Rust

Future Plans

• Adding a Japanese language mode
• Adding WebAudio for browser sounds
• Size optimisation of the final WASM bundle
• Improving responsiveness, currently only mostly supports landscape browsers
• Using WebGL + custom models for the game scene
• Polishing the Menu UI
• Fleshing out the tutorial section
• Eventually improving the custom CAS
• Adding an min-max AI that the user can play against

Known Issues / Incomplete:

• Integration
  • Integrals don't have full support yet for Complexe Coefficients (log(n), n^(a/b), e^n)
  • Log, Limit operators don't have full support for Integrals
• Inverses
  • Inverses don't support complex integrals
  • Limit operators don't have full support for complex Inverse functions
• Distributive Property (FOIL) is not fully implemented for polynomial x polynomial calculations
