**CORRECTION*** I have no idea why I put the code in FIxedUpdate. I'm a dummy. USE Update() INSTEAD!!! **WHY DO I PUT THE BACKGROUND ON THE CAMERA??** To answer this commonly asked question: *Usually* your camera follows the player. So when the player moves, the camera moves. This method is perfect for that, since the background only moves when the camera moves. Meaning the background moved when the plsyer moves. You don't have to put the background on the camera, but you would have to reverse my script to get it working outside of the camera. BUT if you want a moving background where the camera stands still, this implementation is not going to work. Luckily for you, that's way easier, and you just need to repeat the backgrounds at different speeds, using something like Mathf.repeat If you have any questions regarding this, the easiest way to ask me is in my discord. You can ask me here on UA-cam too, just don't expect an instant reply. Thanks for watching!
About your correction. I was having stuttering in my game (only after building) by using Update(). Using FixedUpdate() actually eliminated the stuttering so I would recommend it.
@@aaronswords404 Fixed update is usually used for physics based needs since it updates either never, once, or multiples times a frame depending on the amount of physics changes and frame rate at that specific time
@@ethicalrevolution3294 well, here are some points I might guess: - 5 textures (sprites) duplicated 3 times, 15 entities in total for background - all this textures are being transformed on CPU (via C# script) - if the game lags, the difference between temp and |startpos +- length| might be too big, causing a weird visual effect Much more efficient solution would be just by changing offset of the sprite-texture in shader code per frame, executed on GPU

@Sports Mania With practice we will start understanding. There's a reason they refer to it as a language, and the best way to learn a language is through immersion.
Really appreciate this tutorial. Pretty easy to follow, straight to the point, simple code, and well presented. Helped me build an awesome parallax effect for a class project!
I modified this code a bit so the background is affected by the Y position too (useful if your player character wants to move up or down) using System.Collections; using System.Collections.Generic; using UnityEngine; public class Parralax : MonoBehaviour { private float length, startpos, ypos; public GameObject cam; public float parallaxEffect; // Start is called before the first frame update void Start() { startpos = transform.position.x; ypos = transform.position.y; length = GetComponent().bounds.size.x; } // Update is called once per frame void Update() { float temp = (cam.transform.position.x * (1 - parallaxEffect)); float dist = (cam.transform.position.x * parallaxEffect); float ydist = (cam.transform.position.y * parallaxEffect); transform.position = new Vector3(startpos + dist, ypos + ydist, transform.position.z); if (temp > startpos + length) { startpos += length; } else if (temp < startpos - length) { startpos -= length; } }
Excellent tutorial thank you so much!! For anyone trying to figure out how to get the background to not flip/invert if you're using a player going back and forth, move the camera outside of the player and set camera's position to player.
I know this is not the most recent video, still I would like to point out one thing You've missed: What if camera is following player when he jumps? With the current script, the whole BG would jump with the player which wouldn't look too nice. Everyone who use their brain or know some basics would find the solution in an instant, but here's some tip for complete beginners: You need to add another float for Y axis and define its parameter, then put it in line: transform.position = new Vector3(startpos + dist, transform.position.y, transform.position.z); replacing ,,transform.position.y". That way Your BG will stay in place at Y axis. The video is great anyway, cheers to that!
@@christopherthomas7460 Of course. Well, it actually highly depends on if You want the BG's position to change from time to time or not. In my example You don't want to do that, but the difference in code wouldn't be that big anyway. You could also make it adjustable through the inspector, but I will just use the solid amount as private. In the line You define Your parameters: private float length, startpos; You want to add another one. Let's call it posY, so the line would look like this: private float length, startpos, posY = 9.32f; posY represents the Y position of Your background - take a note I'm not talking about the Backgrounds container, but about one of Backgrounds sub-containers, so taking as an example from the video it would be any of 0 - 4 containers in hierarchy. I did use 9.32f but it is just an example. Then in the Update method, in this line: transform.position = new Vector3(startpos + dist, transform.position.y, transform.position.z); You want to replace transform.position.y with Your posY, so it would look like this: transform.position = new Vector3(startpos + dist, posY, transform.position.z); And that's it. I'm pretty much sure there are other ways to achieve that, but this one is the simplest one that came to my mind. As a summary for those who would still have a problem with understanding how it works: The first version of the line (from the video) will update Y axis of the background based on the Y axis of the camera. What You've changed here is that You said to the program that You want the BG to stay at the solid position You want, so in this case at Y = 9.32f.
Great reply! I was having an issue with this exact thing. Is it as simple as just removing the "transform.position.y" in the script? Thanks for any info
Omg! Yesterday I thought I should request you to make a tutorial on parallax, turns out you've already made one! This is by far the *best* one I've found anywhere. Thank you :D
To people viewing in the future, if the ends of your background asset don't match up (as described in the start of this video), a possible solution could be to import the same background twice, where the second background is flipped horizontally. This will ensure that either end of the background meets another at the exact same height.
A few things to help anyone who has these problems: If you're seeing the edges of the backgrounds when reaching the edge (it means your backgrounds are too short) replace the respecting code with this: if (temp > startpos + (length - offset)) { startpos += length; } else if (temp < startpos - (length - offset)) { startpos -= length; } This will make it so it moves earlier than needs too. You'll also need a public float of offset and just fine-tune it to your needs. If there's small jumping or the size of the children are not all the same (or you're lazy to find the correct X positions for each), have this script attached to each parallax child image (the dupes) and have one of each set to be marked isRight. This will automatically find the size of the image and offset them in the right X pos. public class ParallaxChild : MonoBehaviour { [SerializeField] private bool isRight; // Start is called before the first frame update void OnValidate() { var length = GetComponent().bounds.size.x; if (!isRight) { length *= -1; } transform.localPosition = new Vector3( length, 0, 0); } // Update is called once per frame void Update() {
It’s been 4 years for publishing this video from dani and here we are , man this is super good tutorial thank you helped me with this stupid thing i was struggle with
If anyone is using Cinemachine and is having a glitch where the background sprite doesn't properly loop when you reach the end, try changing length = GetComponent().bounds.size.x; in the start method to length = GetComponent().size.x;
Idea: you can make many variations of a background tile, and as long as its seamless with each one, you can make the background have a little bit of random variation
Это просто потрясающе! Искал несколько дней как сделать паралакс эффект везде предлагали странные и громозкие способы , а тут пару строчек кода и все идеально работает! Спасибо!!!!!!!!!!!
This is a good strait forward tutorial. The game I'm working on right now could use a background, so now that I have the code all I need to figure out is the art! Thanks
If you'd like part of the BG to auto-scroll use this: (NOTE: paralaxEffect should be something like 0.01 in the editor) using UnityEngine; public class Parallax : MonoBehaviour { public GameObject cam; public float parallaxEffect; public bool autoScroll = false; private float length, startpos; // Start is called before the first frame update void Start() { startpos = transform.position.x; length = GetComponent().bounds.size.x; } // Update is called once per frame void Update() { float temp = cam.transform.position.x * (1 - parallaxEffect); float distance = (cam.transform.position.x * parallaxEffect); float desiredXPos = startpos + distance; if(autoScroll) { // this will push bg to the left desiredXPos = transform.position.x - parallaxEffect; } transform.position = new Vector2(desiredXPos, transform.position.y); if (temp > startpos + length) { startpos += length; } else if(temp > startpos - length) { startpos -= length; } } }
If anyone has issues with their backgrounds moving around weirdly and not repeating properly, make sure only the parent backgrounds have the script, not the children.
went trough hell to log into my account here at school, just to tell you THANK YOU! omg I was struggling for so many hours and it was because of this... Anyways thank u fr fr
hi guys. ı'm very new at unity. ı couldn't understand what he means here: float temp = (Cam.transform.position.x) * (1 - parallaxEfect); float dist = (Cam.transform.position.x * parallaxEfect); can you help?
ok, so im pretty new to unity(so im probably wrong), but i do believe i can understand this, float temp is how long until it repeats, and float dist is telling the parallax efect to move, and once it gets one camera distance away its going to reset
Float is a datatype where you can insert integer variabal with decimals also . Cam is the short form of camera and cam is a function which specifies the position and direction of the camera we use x for storing position value . There are vector 3 where we can use x y and z . In vector 2 we can store value of x and y .'transform' is basically a function you need to write before storing value x or y or z . You first need to learn coding unity c# before doing this there are a lot of videos on unity c# coding watch it they will surely help you👍
@@fuleswaripal9536 thank you for your comment FulesWari. I'm not new at codding ı already know what you explain above. ı just couldn't understant the logic behind that part .... 1- parallaxEfect);

@@bradmcdaniel3004 I found the mistake 😁 Actually my both if conditions are cheaking greater then that's why they all are blinking. You can check yours also👍
Maybe someone will see my comment and have a tiny bity jitter on the background just really a little bit jitter... Make sure the edge of the Background really connect to it's edge, you can zoom in and try 1 by 1 exact number so it can connect to it's really edge. also i use public void FixedUpdate() and it does work really smooth, i only put the background only to the camera, but not with the Ground that Player will step on it, don't forget to thanks to @Dani for the tutorial, it really works!
different pieces would be easy, you'd just have to place them all in order like in the video. If you want them to be random tho you'd prbly have to make a random range and then instantiate them in location... or w8 better idea.. Maybe try replacing the pictures with empty game objects that move in this parallax fashion. Then every time you force one to move you also make it switch image... something like that.
What image size should I use for the background? As big as possible so it can be shrunk down with no loss of quality? I'm making a 2D side scroller, but I'd like for it to look good with smooth lines and stuff even on my 4k display at full screen.
@@ItsCoderDan Hey guys, here is much simpler way to make same stuff in unity, but be careful it is on russian, lol. check this out: ua-cam.com/video/t-2DP4UUC5E/v-deo.html
So I needed the background to move from up to down infinitely while my camera would stay in place so I changed the script a bit. Might be useful for someone so here it is: public class Parallax : MonoBehaviour { private float length, startpos; public float parallaxEf; private float speed = -0.01f; //ypu can change this private float distFromMiddle = 0; //keep it 0 void Start() { startpos = transform.position.y; length = GetComponent().bounds.size.y; } void Update() { distFromMiddle = distFromMiddle + speed; float dist = (distFromMiddle * parallaxEf);
transform.position = new Vector3(transform.position.x, startpos + dist, transform.position.z); if (dist < startpos - length) { transform.position = new Vector3(transform.position.x, startpos - length, transform.position.z); distFromMiddle = 0f; } } }
I am having trouble, I dont have layered background like you, but ive followed as closely as I can anyways. When the camera scrolls, all the images merge together and only repeats when the camera is completely out of the image
This happend because you attach the script to the background object, try to remove the script on the child object, and apply the script ONLY to the parent object
For those having trouble with implementing a vertical solution: create a new script, e.g "Yparallax" and follow a similar approach public class Yparralax : MonoBehaviour { private float length, startpos; public GameObject cam; public float parallaxEffect; private void Start() { //make sure these are ."y"s startpos = transform.position.y; length = GetComponent().bounds.size.y; } private void Update() { float temp = (cam.transform.position.y * (1 - parallaxEffect)); float dist = (cam.transform.position.y * parallaxEffect); //make sure the x poition stays the same, and the y is changine with "dist" transform.position = new Vector3(transform.position.x, startpos + dist, transform.position.z); } //no need for repeating } hope this helps :)
As you put the BG under the cam , when you try to adjust the cam you also move the background images , it makes designing very hard. You better update your paralax code to work without this hierarchy dependency. A am working on updating the code but I am a little new in unity, if you can update It will make the tutorial more relevant.
Mainly because I've had some problems using the normal Update method when working with cameras. Sometimes the background moves in a choppy and jittery way, but using FixedUpdate() fixed it for me. But in theory normal Update should work fine.
@@Danidev It was probably because of Physics related things. Physics run in a fixed update, thus when moving stuff with Rigidbody, for example, you get choppy movements because while Update has already updated position for camera and new renders come from a different position. Other stuff is still standing still until physics update. So it's kind of 3 frames freeze usually depending on the frame-rate ofc.
**CORRECTION***
I have no idea why I put the code in FIxedUpdate. I'm a dummy. USE Update() INSTEAD!!!
**WHY DO I PUT THE BACKGROUND ON THE CAMERA??**
To answer this commonly asked question:
*Usually* your camera follows the player. So when the player moves, the camera moves. This method is perfect for that, since the background only moves when the camera moves. Meaning the background moved when the plsyer moves.

This will automatically find the size of the image and offset them in the right X pos.

[SerializeField] private bool isRight;
// Start is called before the first frame update
void OnValidate()
{
var length = GetComponent().bounds.size.x;
if (!isRight)
{
length *= -1;

transform.localPosition = new Vector3( length, 0, 0);

Such an easy way to get a real cool effect which I've always seen and admired in some of the games I've played. Thanks!
You rock man, amazing video, I thought that might be some issue with Cinemachine but it actually worked perfect, thanks a lot!
This helped me very much. Thanks Dani.
If anyone has issues with their backgrounds moving around weirdly and not repeating properly, make sure only the parent backgrounds have the script, not the children.
went trough hell to log into my account here at school, just to tell you THANK YOU! omg
I was struggling for so many hours and it was because of this... Anyways thank u fr fr
And you come to save me time trying to figure it out myself. Thanks.
Thanks for sharing this great tutorial. I will need it for my 2D Game!
hi guys. ı'm very new at unity. ı couldn't understand what he means here:
float temp = (Cam.transform.position.x) * (1 - parallaxEfect);
float dist = (Cam.transform.position.x * parallaxEfect);
can you help?
I don’t either, but I upvoted, so hopefully someone gets you an answer soon. If you figure it out I’d love to know!
ok, so im pretty new to unity(so im probably wrong), but i do believe i can understand this, float temp is how long until it repeats, and float dist is telling the parallax efect to move, and once it gets one camera distance away its going to reset
Float is a datatype where you can insert integer variabal with decimals also . Cam is the short form of camera and cam is a function which specifies the position and direction of the camera we use x for storing position value . There are vector 3 where we can use x y and z . In vector 2 we can store value of x and y .'transform' is basically a function you need to write before storing value x or y or z . You first need to learn coding unity c# before doing this there are a lot of videos on unity c# coding watch it they will surely help you👍
@@fuleswaripal9536 thank you for your comment FulesWari. I'm not new at codding ı already know what you explain above. ı just couldn't understant the logic behind that part .... 1- parallaxEfect);
You always motivated me with your devlogs and now you are helping me with your tutorials!
excellent tutorial. I implemented this in my game. Thank you. I will credit you. :)
What's the name of your game ?
Don't understand anything but simply following the instructions is doable. Thank you very much
bruh i watched this a few days ago looking for a tutorial and found this but didnt notice it was dani lmao
Dani Before: chill
Dani Now: *_milk_*
Before writing the last if else code my scene working fine but after that,
When i hit the play button all the layers started blinking ???
What to do any suggestions?? 😕😕
Idk but I liked the comment so more people see ur comment
Same!
@@bradmcdaniel3004 I found the mistake 😁
Actually my both if conditions are cheaking greater then that's why they all are blinking. You can check yours also👍
Vishnu J ahhh ok hopefully my issue just as minor 💀
I had problems too, is not the best solution but i just made the bg as big as my level and didnt use the infinite copy part
i just realised how good of a programmer dani is
the biggest question is "WHICH WINDOWS VERSION DO U USE?!?!?"
This was just what i needed, u made my day better Dani👍
you're the best. Thank for the help.
Time to use this in my super mario world clone which me and the rest of inverted productions is working on.
the code :D :
using UnityEngine;
public class Parallax : MonoBehaviour
{
private float length, startpos;
public GameObject cam;
public float parallaxEffect;
// Start is called before the first frame update
void Start()
{
startpos = transform.position.x;
length = GetComponent().bounds.size.x;
}
// Update is called once per frame
void Update()
{
float temp = (cam.transform.position.x * (1 - parallaxEffect));
float dist = (cam.transform.position.x * parallaxEffect);
transform.position = new Vector3(startpos + dist, transform.position.y, transform.position.z);
if (temp > startpos + length) startpos += length;
else if (temp < startpos - length) startpos -= length;
}
}
wow thats really cool 👍
This works, but my background images are shaking alot. Anyone with a solution?
thx Dani from the past i needed this. also your future self motivate me to do game development
its weird to see him not cracking jokes
yep
i really like this tuff and it actually has helped me with a 2d game im working on. he really should do more on either this channel or danitutorials.
What is Karlson?
oh Karlsson IS JUST A LIITLW GME OM WORKING WISHLIST NOW BONERS
@@dittodolphinoI was gonna say the same thing rip Dani
Maybe someone will see my comment and have a tiny bity jitter on the background just really a little bit jitter... Make sure the edge of the Background really connect to it's edge, you can zoom in and try 1 by 1 exact number so it can connect to it's really edge.
also i use public void FixedUpdate() and it does work really smooth, i only put the background only to the camera, but not with the Ground that Player will step on it,
don't forget to thanks to @Dani for the tutorial, it really works!
What would be the easiest way to add variety? Like instead of the same foreground element every time, it's one of a possible 5 that appear.
different pieces would be easy, you'd just have to place them all in order like in the video.
If you want them to be random tho you'd prbly have to make a random range and then instantiate them in location... or w8 better idea..
Maybe try replacing the pictures with empty game objects that move in this parallax fashion. Then every time you force one to move you also make it switch image... something like that.
Stunning. Flawless. Perfect tutorial.
When my (example: mountains) move from the back to the front they do not move back as I go left
Thank you Dani, still 1 year later useful.
Where can I get the sprites he's using? Cant find them on his dc
discord
I am also looking for the same. Can anyone please provide links to the assets. Can't find on Discord.
bruh this legend is helping me with tutorials now?
It's really nice. worked with me, but when my Character go backwards the Parallax bugs and the sprites doesn't duplicate at real time. Need help
Try this:
else if(temp < startpos) { objPosition -= length; }
Dani before insanity
Lmao I had no idea that Dani did unity tutorials
But still thank you
Epic script for parallax effect. Dani's best!
What image size should I use for the background? As big as possible so it can be shrunk down with no loss of quality?
I'm making a 2D side scroller, but I'd like for it to look good with smooth lines and stuff even on my 4k display at full screen.
Yeah then you should go for a 4k image size. It's better to scale down for sure, just make sure it's no too big. That could hurt your performance.
Thanks Dani for the tutorial!
Who didn't find this before but got recommended now
i was searching for it :p, although i had no idea Dani made a totorial on this
@@ItsCoderDan Hey guys, here is much simpler way to make same stuff in unity, but be careful it is on russian, lol. check this out: ua-cam.com/video/t-2DP4UUC5E/v-deo.html
Perfect tutorial. Simple, easy to use, can be applied in many ways. 👍
Nice Tutorial!
But for some reason, if i walk to the left , it works perfect, but if i walk to the right they repeat to late
A bit late but just add another bg to the right then :)
First of all, I really appreciate it, because your work is very helpful to me
So I needed the background to move from up to down infinitely while my camera would stay in place so I changed the script a bit. Might be useful for someone so here it is:
public class Parallax : MonoBehaviour
{
private float length, startpos;
public float parallaxEf;
private float speed = -0.01f; //ypu can change this
private float distFromMiddle = 0; //keep it 0
void Start()
{
startpos = transform.position.y;
length = GetComponent().bounds.size.y;
}
void Update()
{
distFromMiddle = distFromMiddle + speed;
float dist = (distFromMiddle * parallaxEf);
transform.position = new Vector3(transform.position.x, startpos + dist, transform.position.z);
if (dist < startpos - length)
{
transform.position = new Vector3(transform.position.x, startpos - length, transform.position.z);
distFromMiddle = 0f;
}
}
}
Thanks
@@NomansSkywalker its work nice while cam stay in one position, nice to use in menu backgrounds thhx
the simplex parallel bg i saw on youtube so cool thanks for sharing man keep make more tutorials
Thanks! That's why I made this video :D
If you hold alt while dragging images into unity it won't make an animation.
FINALLY! A Parallax tutorial that works for me
Glad to hear :)
I am having trouble, I dont have layered background like you, but ive followed as closely as I can anyways. When the camera scrolls, all the images merge together and only repeats when the camera is completely out of the image
This happend because you attach the script to the background object, try to remove the script on the child object, and apply the script ONLY to the parent object
@@FrozenWolf001 legend
@@FrozenWolf001 For some reason this doesn't solve the issue for me. I'm getting an error because there is no SpriteRenderer on the parent object.
@@noodleplexium5953 Your parent Object must be the original image instead of duplicated image or Empty GameObjects
@@FrozenWolf001 You saved me!!! Thank you very much!!!
WOW this blew me away..clean simple and beautiful
Thanks a lot!
Glad to hear that!
Hi, how do you handle different aspect ratio when the bg wont cover the whole viewPort?
aspect ratio doesn't affect the camera much. All you have to do is adjust the viewport's height and width to suit your background
@@EdwinCreativesI see, how do you adjust the view port?
DANI MADE TUTO ON HIS MAIN?!?!? i never knew abut did :O
Thank you :))
Great video, really helped me to understand the concept. Thank you very much
i've tried so hard x.x and it's just not repeating the layers at all
Yupp, same for me. You gotta use this
length = GetComponent().size.x;
so dont write bounds
Dani tutorial lives
Great tutorial! My only problem is when I move it, it is very choppy. It takes a while to load in, I have a decent laptop so I am not sure why.
did you fix it bro?
great demo - thanks and seems easy!
Hey man, nice tutorial! I have a question... How do you get that Windows classic theme? I love it!!
If you're on Win 7, right click on desktop > preferences > and then select classic theme :D
@@Danidev Oh! I think that you're using Windows 10 u.u, thank you anyway
Who would have guessed that when I’m trying to learn to code the milkman himself shows up at my doorstep and teaches me a lesson
For those having trouble with implementing a vertical solution:
create a new script, e.g "Yparallax" and follow a similar approach
public class Yparralax : MonoBehaviour
{
private float length, startpos;
public GameObject cam;
public float parallaxEffect;
private void Start()
{
//make sure these are ."y"s
startpos = transform.position.y;
length = GetComponent().bounds.size.y;
}
private void Update()
{
float temp = (cam.transform.position.y * (1 - parallaxEffect));
float dist = (cam.transform.position.y * parallaxEffect);
//make sure the x poition stays the same, and the y is changine with "dist"
transform.position = new Vector3(transform.position.x, startpos + dist, transform.position.z);
}
//no need for repeating
}
hope this helps :)
Exactly what i wanted ! Thanks !
cant wait for the second tutorial
As you put the BG under the cam , when you try to adjust the cam you also move the background images , it makes designing very hard. You better update your paralax code to work without this hierarchy dependency. A am working on updating the code but I am a little new in unity, if you can update It will make the tutorial more relevant.
Fantastic tutorial man -- you really helped me out 👍 Going to use this script in my game.
Awesome!
Thanks for the great tutorial. One question - why do you use FixedUpdate if you're not updating physics?
Mainly because I've had some problems using the normal Update method when working with cameras. Sometimes the background moves in a choppy and jittery way, but using FixedUpdate() fixed it for me. But in theory normal Update should work fine.
@@Danidev I'll keep that in mind next time i'm working with the camera!
@@Danidev It was probably because of Physics related things. Physics run in a fixed update, thus when moving stuff with Rigidbody, for example, you get choppy movements because while Update has already updated position for camera and new renders come from a different position. Other stuff is still standing still until physics update. So it's kind of 3 frames freeze usually depending on the frame-rate ofc.
@@Danidev still experiencing little jittering even after fixed update, tried a everything i know, so exhausted
Try using LateUpdate to move the camera, as it is called every frame, but after everything else is done moving.
thanks dani 3 years ago! ;D really helped me!
I cant do art dani, so can i use this for a game?
Uniqueness brings attention. Download free tree, bush, rocks, mountain brushes to make the background.
does anyone know why the background does not move smoothly but has a flickering effect? I followed the tutorial step by step but I have this problem
Hi, amazing tutorial! where i can download the resources? the background? i joined into discord but i dont find the resources
Now it's all about Karlson, no one cares anymore about any other game.
That's because you join the Discord group way too late. Dani might have forbidden the project files or hidden or even deleted
wait i did not know this video is from dani! amazing
