Limits

• Game version: Steam Happy Wheels 1.99.2 only. A new game build needs a new launcher.
• Legal copy: The launcher patches files you already own. Do not redistribute the game.
• Obfuscation: Character classes, Pixi exports, and Box2D live behind minified webpack modules. Those IDs belong in core/hw-mod-sdk.js, not in your mod.
• One tick bus: Wrap renderer.render through HWMod.on('tick'). Do not add a second world.Step.
• Physics: No zero-mass dynamics, no double impulses. If Jimbob’s Multiplayer Shared Physics is running, it owns stepping.
• web[]: Flat filenames only. No web/lib/foo.js in the array.
• Silent Electron errors: A broken electronMain is skipped. Check the main-process console if your bridge never appears.
• Catalog: Strangers cannot self-publish yet. Ask on Discord. Store ids are at most 48 characters; the runtime allows 63 after the first character.
• Steam verify: Restores stock files. Players run the launcher again.
