I'm a beginner in Cocos2D (not in Obj-C) facing to a silly problem:
I'm creating a test program that loads a TileMap (which is finally working), and then I've tried to add a transparent sprite on it but it shows with black background on it.
I'm fully sure of the transparency of this sprite (made with Photoshop CC, saved as a PNG-24 with Transparency) because when I load it on a UIImage, then showing it on a test UIView, it is definitely transparent.
I've tried lot of things (and I'm searching since more than a hour) without success.
What could be wrong ?
Thanks for your help
