Points VS. Pixels
We should konw that Cocos2D uses a point system to help position objects on the normal iPhone display (480 × 320 pixels) and the retina display (960 × 640 pix- els).
In the nonretina display a point equals a pixel, but in the retina display a point equals two pixels.
When you set a sprite at position to 24 points, on an iPhone 3G or 3GS it equates to exactly 24 pixels from the left side.
On an iPhone 4 with the retina display it is 48 pixels from the left side.
In both cases, to the player Ole will look like he is in the exact same position onscreen.
