Use interrupt to create a delay in Minetest Luacontrollers

luacontroller_interrupt.lua

local delay = 1

if event.type == 'program' then
  interrupt( delay, 'Once' )
  interrupt( delay, 'Loop' )
end


if event.type == 'interrupt' then
  if event.iid == 'Once' then
    print( 'Run once' )

  elseif event.iid == 'Loop' then
    print( 'over and over' )
    interrupt( delay, 'Loop' )
  end
end

This example causes an overheat after a few seconds.

yea, it was to illustrate the difference between those two methods to somebody on Discord. They were having the same issue; having it loop then overheat, when it should have only run once.

That would depend on your server and your uses. Try increasing the delay to reduce the chance of it happening. Otherwise, rebuild machine, or tweak server settings.

I found out that an activated modlib causes the overheating.
