Description
Returns precise time in seconds relative to some arbitrary point. <syntaxhighlight lang="lua"> (number) = os.timer() </source>
Return values
Returns (number) precise time in seconds relative to some arbitrary point
Example
<syntaxhighlight lang="lua"> local function onEnterFrame(event) -- get the precise timer local t = os.timer()
-- animate r,g,b multipliers of color transform local r = (math.sin(t * 0.5 + 0.3) + 1) / 2 local g = (math.sin(t * 0.8 + 0.2) + 1) / 2 local b = (math.sin(t * 1.3 + 0.6) + 1) / 2
-- set color transform bitmap:setColorTransform(r, g, b, 1)
-- update the positions of dots reddot:setX(90 + r * 280) greendot:setX(90 + g * 280) bluedot:setX(90 + b * 280) end </source>
