# Haxe Compile Haxe games to JavaScript and ship them to Wavedash with a one-line build. Source: https://docs.wavedash.com/engines/haxe Haxe targets JavaScript natively, so any Haxe program that renders to a `` runs on Wavedash. No runtime is shipped alongside your game — the compiler emits a single `.js` file you load from a static HTML shell. ## Build for web Write a `build.hxml` that emits JavaScript: ```hxml -cp src -main Main -js build/main.js -D js-es=6 -D no-traces ``` Then run `haxe build.hxml`. The compiler writes `build/main.js`. Commit a matching `build/index.html` that includes it: ```html My Haxe Game ``` ## SDK integration Call the JavaScript SDK from Haxe with `js.Syntax.code`. Wavedash injects `Wavedash` as a global before your script runs. **Calling `Wavedash.init()` is required.** Your game stays hidden behind the Wavedash loading screen until you do. Call it once your game is ready to play. ```haxe import js.Browser; class Main { static function main() { // DOM is being parsed — report that we've started. js.Syntax.code("Wavedash.updateLoadProgressZeroToOne(0.2)"); Browser.window.addEventListener("load", onLoad); } static function onLoad(_) { // Window "load" fires once all subresources (images, scripts) are ready. js.Syntax.code("Wavedash.updateLoadProgressZeroToOne(0.7)"); // set up your canvas, game loop, input handlers, etc. // Assets and game state initialized — signal ready and start the loop. js.Syntax.code("Wavedash.updateLoadProgressZeroToOne(1.0)"); js.Syntax.code("Wavedash.init({ debug: true })"); Browser.window.requestAnimationFrame(loop); } } ``` For anything more than a one-off call, wrap the SDK in a Haxe extern so the compiler can type-check your usage: ```haxe @:native("Wavedash") extern class Wavedash { static function init(config: Dynamic): Bool; static function updateLoadProgressZeroToOne(progress: Float): Void; static function uploadLeaderboardScore(id: String, score: Int, keepBest: Bool): js.lib.Promise; // ...add more as you need them } ``` ## wavedash.toml ```toml game_id = "YOUR_GAME_ID_HERE" upload_dir = "./build" entrypoint = "index.html" ``` The example repo commits both `build/index.html` and a prebuilt `build/main.js` so you can run `wavedash dev` without a Haxe toolchain on hand.
