I have an image that I want to use as a background for a side-scroller. The problem that I am having is looping the image infinitely. How do I go about this? |

Sure, I put the code as an image. The first is the code and the second is the background. |

Just to clarify, this background scrolls as the player moves along? |

Not exactly. I want the background to scroll while the player moves freely about the screen. My goal is to first get the background scrolling in a seamless loop first, and then I wish to move onto player control. |

I would recommend having a variable(x) that contains the x position of the picture (which spot is at x = 0 on the screen) and a variable that holds the size of the picture(y) (unless it is a known number you will always use) then once it reaches a point where x+ screenx = y then you will draw the picture at x+screenx as well until x=y (the first picture has looped through) at which point you can reset x to 0. So the code might look like
