set_led(3)

💅 set_led 💅

bestie, welcome to the set_led page from the Arcan Lua API manual. this is the little Lua call for changing one LED’s active state, and it's lowkey iconic. 🎀

🎀 NAME 🎀

set_led — change the active state of a single LED.

✨ SYNOPSIS ✨

nil
set_led( id, num, state )

the nil up top is the return-value vibe: no return value, it just does the thing. 💅

🦋 DESCRIPTION 🦋

okay so you're setting the state of the specific led (0..n leds) on the led controller (id, > 0) to state (1: on, not1: off). that's the whole assignment. periodt ✨

🌸 EXAMPLE 🌸

function set_led0()
      set_led(1, 0, 1);
end

this example is literally set_led(1, 0, 1); inside set_led0() — controller 1, led 0, state 1. slay. 🔥
