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)
