Available since: in development
Class: Pixel
Description
Sets the matrix of the Pixel's texture.
Pixel:setTextureMatrix(matrix)
Parameters
matrix: (Matrix) the matrix
Example
-- a pixel holding a repeatable power of 2 texture
local tex = Texture.new("gfx/myimg.jpg", false, {wrap = TextureBase.REPEAT})
local img = Pixel.new(tex, tex:getWidth(), tex:getHeight())
stage:addChild(img)
-- the matrix
local m = Matrix.new()
-- some vars
local flow = 0
local flowspeed = 0.09
function onEnterFrame(e)
flow += flowspeed
m:setRotationZ(math.sin(flow)) -- rotate matrix on Z axis
img:setTextureMatrix(m) -- apply modified matrix
end
stage:addEventListener(Event.ENTER_FRAME, onEnterFrame)
