About the timelapse - like the music
I suggest You use static imports in Eclipse so You dont have to type GL11 everywhere (you can find it in Window -> Preferences -> Java -> Editor -> Content assist -> Favories).
And yeah, You would be fine flipping the player image in code. AFAIK TextureLoader.load takes a boolean parameter that indicates that.
Thanks for your response and your tips. I am using static imports now, just changed it. It is more efficient! :-) I'll see what parameters the TextureLoader takes when I get back home.
