# Implementing Scrolling Background in LibGDX game

I am making a game in LibGDX. After working for whole a day..I could not come out with a solution on Scrolling background.

My Screen width n height is 960 x 540. I have a png image of 1024 x 540. I want to scroll the background in such a way that it contuosly goes back with camera

x-- as per camera

I tried many alternatives... drawing the image twice ..did a lot of calculations and many others.... but finally end up with this dirty code

if(bg_x2 >= - Assets.bg.getRegionWidth())   {
//calculated it to position bg .. camera was initially at 15
bg_x2 = (16 -4*camera.position.x);
bg_x1=bg_x2+Assets.bg.getRegionWidth();
}
else{
bg_x1 = (16 -4*camera.position.x)%224;  // this 16 is not proper
//I think there can be other ways
bg_x2=bg_x1+Assets.bg.getRegionWidth();
}

//drawing twice
batch.draw(Assets.bg, bg_x2, bg_y);
batch.draw(Assets.bg, bg_x1, bg_y);


The Simple idea is SCROLLING BACKGROUND WITH SIZE SOMEWHAT MORE THAN SCREEN SIZE SO THAT IT LOOK SMOOTH. Even after a lot of search, i didn't find an online solution. Please help.

You can use parrallaxBackgroung and ParrallaxLayer classes

They will manage all u need in an optimized manner and also its very easy to implement
