Description
RenderTarget is a texture on which provided Sprite hierarchy can be rendered.
It can be used in any case in which Texture can be used.
Example
Using a texture and updating RenderTarget
--original bitmap
local source = Bitmap.new(Texture.new("crate.png", true))
--render target
local rt = RenderTarget.new(source:getWidth(), source:getHeight())
--bitmap with rendertarget as texture
local bmp = Bitmap.new(rt)
bmp:setPosition(200, 0)
stage:addChild(bmp)
--updating source updated Bitmap
local frame = 0
stage:addEventListener(Event.ENTER_FRAME, function(event)
local r = math.sin(frame * 0.03) * 0.3 + 0.7
local g = math.sin(frame * 0.04) * 0.3 + 0.7
local b = math.sin(frame * 0.05) * 0.3 + 0.7
source:setColorTransform(r, g, b, 1)
frame = frame + 1
rt:draw(source)
end)
