| This variant is not supported in that and later versions. |
Synopsis
love.timer.sleep( ms )
Arguments
number ms- Milliseconds to sleep for.
Returns
Nothing.
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 30 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
