dtmath-wit

Wasm interface for dtmath which is used to simulate Darktide mechanics in the wartide calculator.

dtmath supports:

• damage (not all attacks currently)
• cleave
• weapon stats (for damage/cleave)
• stat buff modifiers (like rending)
• action resolver (sequence names for attacks)

All data used in dtmath for weapons/breeds/etc is embedded in the binary.

Usage

Get the latest dtmath.wasm from releases and generate bindings with supported runtimes.

A JavaScript/TypeScript package is also available with each release.

See JavaScript examples at examples.
