Grid = Core.class(Sprite)   function Grid:init(rows, columns, w, h, bColor, fColor, lColor, alpha)   local width = columns*w local height = rows*h     local rect = helper:createRectangle(width, height, bColor or 0x000000, alpha or 0.5, 8, fColor) ---simply create an Rectangle self:addChild(rect)     local lines = Shape.new() ---this lines not show on mac or ios device lines:setFillStyle(Shape.NONE) lines:setLineStyle(1, lColor or 0xffffff,alpha or 0.5)   lines:beginPath() for i = 1, rows - 1 do lines:moveTo(0, i * h) lines:lineTo(width, i * h) end   for i = 1, columns - 1 do lines:moveTo(i * w, 0) lines:lineTo(i * w, height) end   lines:endPath()   self:addChild(lines) end

the lines object is drawed on windows player, but when run on mac player or iphone devies, the lines is not drawed.

And when commit these code
local rect = helper:createRectangle(width, height, bColor or 0x000000, alpha or 0.5, 8, fColor) ---simply create an Rectangle
self:addChild(rect)

only Horizontal lines was drawed on windows player.

I know when I were drawing a "dropping trajectory" of a falling object using 1px line, then on some resolutions moving object left/right on the screen, line disappeared.
I've tried using 2px or 3px lines and it worked fine. I think it can be problem of automatic scaling, that object is too small to be shown.

really？
I will try when I got home,thanks.

Exactly, that is the reason why.
