First of all, I’m spanish and my English not is perfect, but i’m trying dot you understand me.
I’m trying to put a sprite in a body (or a texture, the theme is dot be a image), so, for do this, I have downloaded Box 2D editor and save my file. After, I find a tutorial for implement the body for my game, but when I run my game it look like this:
Body is moving independently the sprite, so it’s no cool…
How can I put my sprite in the body correctly?
My code:

The other class contain a setScreen(new Base()); method.
