using Gtween with anchor points.

uncleking

Hi, I am trying to tween a anchor point along with rotation using gtween. I am using the GiderosCodingEasy Library

here is my code.
-- start code
local angle = 15;

local star = Bitmap.new(Texture.new("star.png"))
star:setPosition(500, 280)
star:setAnchorPoint(0.5, 0.5) -- start with center of the image.
star:setRotation(angle)
stage:addChild(star)


local animate = {};
animate.rotation = 360 + angle

local properties = {};
properties.delay = 1;
properties.dispatchEvents = false

-- tried this doesn't work
-- animate._anchorX = 2.0
-- animate._anchorY = 2.0

animate.anchorX = 2.0
animate.anchorY = 2.0


local properties = {};
properties.delay = 0;
properties.dispatchEvents = false


local gtweener = GTween.new(star, 5, animate, properties)
-- end code.


The error i am getting is
GiderosCodingEasy/GiderosCodingEasy.lua:347: Parameter 'param' must be one of the accepted values.
stack traceback:
GiderosCodingEasy/GiderosCodingEasy.lua:347: in function 'get'
GiderosCodingEasy/gtween.lua:385: in function 'init2'
GiderosCodingEasy/gtween.lua:212: in function 'setPosition'
GiderosCodingEasy/gtween.lua:81: in function

Any ideas what i am doing wrong ?

@uncleking because natively anchorpoint is not supported
And for some reason, no one ever requested it in GiderosCodingEasy

But is should be quite easy to fix.

pushed new version, fixing it to github
now you can tween anchorX and anchorY properties

that was awesomely fast !!!!

(side note ! i did almost same changes you did )
