A better way to fade a scene in...

I've been using scene manager to fade scenes in and out.
The problem I found is that if you have different layers of images, you'll get an odd effect where you can see the edges of the graphics.

Here's the code:
To fade in a scene:
-- Add black overlay local blackOverlay = Shape.new() blackOverlay:setFillStyle(Shape.SOLID, 0x000000) blackOverlay:beginPath() blackOverlay:lineTo(0, 480) blackOverlay:lineTo(320, 480) blackOverlay:lineTo(320, 0) blackOverlay:lineTo(0, 0) blackOverlay:endPath() self:addChild(blackOverlay) -- Now fade it out local tween = GTween.new(blackOverlay, .4, {alpha=0}) |
local tween = GTween.new(blackOverlay, .6, {alpha=1}) |
