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.

Examples

Using as 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)
