In this video I'm going to show you how to create an endless background in Unity
============

In this video, we cover:
1:10 - Create C# Script
1:50 - Calculating Screen Boundaries
2:45 - Cycle through each of our background objects and load them on the screen
3:50 - Creating a function to setup the scene
6:40 - Creating a function to move our background elements to create a seamless effect
9:15 - Repositioning objects to fill the screen
10:20 - Adding a choke value to fix seams

Seriously you got the best logic out of all those scrolling tutorials...I tried all of them, yours is the best for scrolling so far.

[idontdogood]

Your definitely one of the better channels for unity tutorials

[EnemyOTS]

I swear to god I threw your code on the camera and another camera follow code and another parallax code that doesn't repeat the backgrounds and all the sudden I have the smoothest Parallax I've ever done in my life. Thank you for the amazing video. Time to analyse that long ass code to understand wtf is going on :D

[nand]

gonna be completely honest, really helpful even though i only used 3 lines of code lol. thank you so much for the tutorial, people like you are amazing!

[KnrdoftheRoundTable]

You have an excellent explanation in your video that is very easy to follow, this is really well done!

[ryan_garfield]

Wow, this worked surprisingly well, thanks man!

[mouad]

Finally found something useful and works thanks man.

[marcusmorrow]

really good tutorial. I coded along side you and this code worked like a charm. Thanks man.

Hey :-) Wondefull and advance tutorial! I wrote whole script but my transform is y-asis, and i don't know how force move camera.

[benhoreluk]

It does what you said it would. Good job.

[ossiexs]

Nice video and animation again
But this so hard to understanding the code for noob like me 😆,
i will need this video later

[augustgustavo]

what if I have a vertical camera and background movements and not in horizontal movements?

[cAnuL]

Everyone suffering from background loading late in visible area:.

if (transform.position.x + screenBounds.x > + halfObjectWidth / 2)

This solved the issue for me.

[SocrateA]

this by far the best Infinte scrolling by far Keep Up

Hey!
Very helpful tutorial, but how to make that this elements would move with diffrent speed?
Thanks in advance :D

[cheery-hex]

thank you very much! I couldn't figure out why mine was looping only 3 times... until I discovered it only does it with a prefab bckgrnd..

[codersexpo]

This is very good! TY. Now, I need to try and adapt this for moving in any direction. This only seems to work going left to right. If I turn and go up or down along the y, it does not work. :-( Its a good start though. Thanks.
Update: ok so getting to be endless in the y direction is simple enough, just add another if/if else section to repositionChildObjects that looks at the
transform.position.y, screenBounds.y > lastChild.transform.position.y, and - halfObjectWidth * 2 of the new vectors y coordinate.
The only real challenge now is fixing the flicker between images on x and y IF you move towards a corner. Any help on this would be great!

The script gave some issues with my camera position. I Fixed the calculation of the camera width by adding a new function.
private Vector2 GetCameraBounds(Camera camera)
{
Vector2 lowerLeft = camera.ScreenToWorldPoint(new Vector3(0, 0,
Vector2 upperRight = camera.ScreenToWorldPoint(new Vector3(Screen.width, Screen.height,
return new Vector2((upperRight.x - lowerLeft.x), (upperRight.y - lowerLeft.y));
}

Great tutorial! Used this but for vertical sadly didn't work.

[hishamfarag]
