love.timer.sleep

love.timer.sleep

Pauses the current thread for the specified amount of time.

This function causes the entire thread to pause for the duration of the sleep. Graphics will not draw, input events will not trigger, code will not run, and the window will be unresponsive if you use this as "wait()" in the main thread. Use love.update or a Timer library for that instead.

Examples

Use sleep to cap FPS at 30

function love.update(dt)
   if dt < 1/30 then
      love.timer.sleep(1/30 - dt)
   end
end

More sophisticated way to cap FPS

This takes into account the time spent updating and drawing each frame.

function love.load()
   min_dt = 1/30
   next_time = love.timer.getTime()
end
 
function love.update(dt)
   next_time = next_time + min_dt
 
   --rest of function here
end
 
function love.draw()
   --rest of function here
 
   local cur_time = love.timer.getTime()
   if next_time <= cur_time then
      next_time = cur_time
      return
   end
   love.timer.sleep(next_time - cur_time)
end
