Description

Returns precise time in seconds relative to some arbitrary point.

(number) = os.timer()

Return values

Returns (number) precise time in seconds relative to some arbitrary point

Example

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
