Chapter 2: I didn't know what to do with the "add(background);" i added it like this
new FlxSprite(0, 0, Sources.ImgBackground);
add(background);
Then Pressed F5 and i got "col: 8 Error: Access of undefined property background.
add(background);"
And i see in the comments allot off people have the same issue ... Or are stuck on chapter 2 too.
Rest off the Tutorial was fine and smooth to follow ;)
