Seperate parallax backgrounds

How do I make my backgrounds to have infinite parallax scrolling, now I know how to have backgrounds on multiple layer with parallax effect but let's say my maps are 10000x10000 format and the game window size is 1024x768 how must I put make it so that each tiled background has infinite width? it runs out of width replacing it with transparency when I move too far to the right causing the tiled background to run out, must I give the background tiles 1000000 width (basically infinite width) or is that a wrong method to give infinite size?

Thanks in advance.

Check out the endless runner template that comes with Construct 2. For that they didn't use tiled backgrounds, but instead just added a new one on the right when needed, and removed any that went offscreen to the left.

If you want to use a tiled background, you could just set the origin to the left and change the width dynamically.

Thanks thehen, I'l do that.

That didn't exactly work, Here's my .capx file to show you what I want to do and what's happening wrong (keep in mind this is only a beta version of my game it's just to show you what I need to do)
