Class: Pixel
Description
Sets the texture position inside the Pixel.
Pixel:setTexturePosition(x,y)
Parameters
x: (number) Pixel texture x coordinate
y: (number) Pixel texture y coordinate
Example
-- a pixel holding a power of 2 repeatable texture
local tex = Texture.new("gfx/image.jpg", true, {wrap = TextureBase.REPEAT})
local img = Pixel.new(tex, tex:getWidth(), tex:getHeight())
stage:addChild(img)
-- some vars
local flow = 0
local flowspeed = 1
function onEnterFrame(e)
flow += flowspeed
img:setTexturePosition(0, flow) -- move the texture pixel on y axis
end
stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
