Module

love.timer

The timer module keeps track of time between frames, so that game objects can be updated in a FPS-independet fashion. The precision of the timer is usually 1ms, although this may vary from system to system. Hardware timers with higher precision are planned, but not implemented at the time of writing.

Functions

getFPS( )	Gets the current FPS.
getDelta( )	ret the current timestep.
sleep( ms )	Delays exection for an amount of time.
getTime( )	Gets approximate time since startup.

Examples

Example 7: Sleeping

function update(dt)
    -- Sleeps 10ms after each udpate. By doing this,

    -- CPU time is made available for other processes,

    -- and your OS will love you for it.

    love.timer.sleep(10)
end

Example 9: Timing code

function load()
    -- Get time before the code to be timed.

    t_start = love.timer.getTime()
    
    -- Load 10 fonts.

    for i=12,22 do
        local f = love.graphics.newFont(love.default_font, i)
        love.graphics.setFont(f)
    end
    
    -- Get time after.

    t_end = love.timer.getTime()
    
end

function draw()
    love.graphics.draw("Spent " .. (t_end-t_start) .. " seconds loading 10 fonts.", 50, 50)
end
