-- null0 - Cyber bindings for the null0 fantasy console
--
-- GENERATED FILE - do not edit by hand. See tools/gen_cart_cyber.js
--
-- This module is baked into the cyber cart-runtime, so carts can just do:
--
-- ```cyber
-- use null0
--
-- fn load():
--   null0.clear(null0.BLUE)
--   null0.draw_circle(100, 100, 50, null0.RED)
-- ```
--
-- Callbacks (load/update/unload/buttonUp/buttonDown/keyUp/keyDown/mouseUp/
-- mouseDown/mouseMoved) are top-level fns in main.cy - implement the ones
-- you need.

-- Sfx parameters.
