[HELP] How to create alpha animation for image?

[Tokio]

I want create a animation for my dx image. The image hide, and appear again continuously. How to make this?

function render ()
	local timeNow = getTickCount()
	local alpha = (timeNow % 510)
	if alpha > 255 then
		alpha = 255 - (alpha - 255)
	end
	local color = tocolor(255,255,255, alpha)
end

 

Each 1 alpha unit of 255 = 1 millisecond. Very easy example.

Which counts from: 0 > 255 > 0 > 255 > 0 etc.

If you want some custom timing: (2s = full animation ON/OFF)

 

local duration = 2000

local alpha = (timeNow % duration / duration) * 510
