Hello Im currently making a game using cocos2d.

Ive already made my animations. Spine is great btw but I have a concern. The images I use are the same size I would place on my screen. I mean I'm using a 1 to 1 image scale with the screen size on the device. But when I add the spine child to the scene I need to scale it down to 0.5 for it to show at the right size.
Why is this if Ive made the animations with the images on a 1 to 1 scale? does Spine reads Scale Factor on cocos2d? I tested an on a non retina and the spine object showed twice the size. I thought this normal because my spine animations and images where made just for retina but on a retina device it was still twice the needed size. If it does use scale factor does it also use the "-hd" convention for retina files?

If its confusing consider this:
On retina device the screen width and height are 960x640 so I draw and imported and animated all the parts of a 200px height character but on the device at 1.0 scale its exactly twice the size on both retina (960x640) and non-retina(320x240). Why is that?

You can check the spine boy example cocos2d project also. In an hd retina device it would never be as big as it is when you run the test.
Check this is an hd screen with the parts at the 100% scale:

And it show twice as big on an hd device:
