For anyone having issues with score display not changing, check if your player object has the tag "Player" selected. It was mentioned in the video but somehow I missed it multiple times, it was driving me insane. My player object was named "Player" so that is why I missed it, it has to be a TAG. :) Also, make sure that you drag your text mesh to the score manager object (text field). Great tutorial btw, thanks! :D
If anyone comes from watching brackeys, how to animate and player movement 2D games or you just use two colliders in your player object and sometimes when you collect a coin the games counts it as two, you could try to reduce the size of the top collider, which is used so you player can crouch, in a way that stays in the same Y offset so your player objetc wont go trough a roof platform without crouching. This worked for me, hopefully it does for you too.
THIS TUTORIAL SAVED MY LIFE!! So well thought out I had no errors in my script. You did go fast for a beginner but that's fine, I just put the video at 0.5 speed to follow along in Unity. Thank you for making this!

(Good Tutorial-THX)For everyone who has problem with score (ui display) changing. I had this problem also, "0" was displaying all the time... I read all comments here , but nothing helps... in my case it was "mistake autofilling in VS" i whant type " private void OnTriggerEnter2D but it automaticly fill normal one "private void OnTriggerEnter" ( for 3D not 2D, and that's not worrking couse 2d object can't collide with 3d one). It's realy simple mistake, but sometimes it could be hard to find. Then if you check all thinngs with TAG's etc. check if all methods are correct. And after that, if you will still have problem, just type something like this: Debug.Log(" +1 coin"); in methods who are involved in coin counting( coin.cs in my case). Play the game and pause it after collecting coin and check Console (in unity), if "+1 coin" not displaying there then something must be wrong... and basicly its how you should search for errors and faults.... I m also begginer in that but that could help in plenty of diffrent situation's,atleast worth of try. Good Luck.

I had an issue with this where the colliders where registering but the coin wasnt destroying its self (this is due from hopping between tutorials because i couldnt find a complete 2d course) anyway the solution is to check that your colliders on your collectables are set to as trigger.
turns out its the Trail Renderer component at the editor, you can add it and set length + color. If your Trail Renderer gives a bright pink afterimage, you need to go to it's "Materials" section and add a material to "Element 0".

i really like the tutorial but i have one question. Why doesnt it work in all scenes i added the scoremanager, the canvas, and a coin? would by great if you could help me :)
Hey F., So you mean that your score comes back to 0 when you change scenes is it ? For that you need a score manager that will follow you across the scenes. It's hard to explain here I would recommend you to have a look on something called dontdestroyonload. here is the link: docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html So your score manager wont be destroyed once you move on to the next level
So I had this problem: for some reason when I had instance = this; in my script, public TextMeshProUGUI text; didnt work. When I removed instance = this; from the script then public TextMeshProUGUI text; started working but there was object reference missing so I added it back and it worked perfectly. Not sure why it didnt work in the 1st place but hopefully this might help some people. Thanks for the tutorial. :)

I got everything working but I have a strange problem. Sometimes when I pick up a coin, the score counts it as two coins. Anyone else experience this? It happens very inconsistently.
maybe instead of using 2 colliders of which im assuming is a square and a circle because that is also what im using lol, maybe a capsule collider? its not perfect but it will do the job
Hey Mate, loved the video however ive had a problem right at the last step im getting an error. NullReferenceException: Object reference not set to an instance of an object Coin.OnTriggerEnter2D Any thoughts?
If you still passing the coins, it might be that the player and the coins are not colliding. Check if the Collision methods are ok and if you applied the tags correctly.
ok so I'm having an issue where the player touches the coin and sometimes 2 coins are added when I touch only 1. The only thing that I can see affecting this could be the colliders I have set up on my player (box on the head and circle on the bottom)
Hey mate yes you are correct it is to due with having the two colliders as both colliders are hitting the cherry at once and causing the coinScore to go up twice instead of once :)

thx man for this tutorial...now i put them into game scene , what about showing the score count of coins with main menu scene and shop scene too to buy items ? because all of there are not in the same scene !...
Hi Ahmed, That's a good idea for a tutoria, it can be made in a very different ways. Once I go forward with the 2d tutorials I will show a way to do that. Thanks for the recommendation.
@Xlaugts, are you still supporting this? Your scripts are working fine and they are also easy to understand. My only issue and I guess it comes from animation, is, that my score is raising from 1 - 4 randomly (I am using 4 grapihcs for a gem animation). Any suggestion how to solve this issue?
I have a question. I did everything you did with the coin and for some reason I go right through it. Any ideas? Never mind I put on collision instead of ontrigger 😅
Hey i know this tutorial is relative old but i want to ask about saving this data (coins) and use it later to buy things from the menu?, i want to use player.prefs but everyone says that is bad, (purchase in the app) soo i really want if you can help me and do a tutorial of this!

Great tutorial! I do have an issue though, because I use 2 colliders for my player (so it can crouch underthings) the coins sometimes count for 2 instead of 1. Anyone have a suggestion to fix it?
You have to go into the coins script and add the following: 1: add 'public bool trigger = false' inside of the coin class, but outside of the OnTriggerEnter2D method. 2: inside the OnTriggerEnter2D method, inside the if(other.gameObject.CompareTag("Player") statement, add another if condition to if (trigger == false) and execute the ScoreManager inside of that. Remember to set trigger to true so your script only loops once. This essentially just creates an internal condition that gets checked and prevents any single coin from being counted twice.
@@doctordoge5058 I watched this video and made the coin system twice because of the duplication of coins. Then i came here and found your comment. Thank you!
The script worked...... until i died and reloaded the scene so basicaly it works on the first try and if i manualy reload it (pressing play button) but if i use the script to reload the scene it dousent count the coins
Hi this works but how do i permanently destroy it? Since I'm going from and to different scenes/levels, but whenever I come back to the scene/level the collectable is still there. Is there any way of destroying it forever?
if you only want to use one sprite, you can just use this script. Isn't as visually pleasing, but much easier! using System.Collections; using System.Collections.Generic; using UnityEngine; public class CoinRotation : MonoBehaviour { private Vector2 rotation; // Start is called before the first frame update void Start() { rotation = new Vector2(0, 1); } // Update is called once per frame void Update() { transform.Rotate(rotation); } }
hi thank you so much for the video it helps me a lot :) I just need help on one thing. Why is it when I collect a coin the score becomes 2 instead of 1?
hey mate you might've fixed this by now but this is due to having multiple collision boxes touching the cherry at the same time, to fix it you may have to fiddle around with your characters collision :)
For anyone having issues with score display not changing, check if your player object has the tag "Player" selected.

thx man for this tutorial...now i put them into game scene , what about showing the score count of coins with main menu scene and shop scene too to buy items ? because all of there are not in the same scene !...
Hi Ahmed,
That's a good idea for a tutoria, it can be made in a very different ways.
Once I go forward with the 2d tutorials I will show a way to do that.
Thanks for the recommendation.
Good video Duude...
great tutorial thank you so much :))
Thank you
@Xlaugts, are you still supporting this? Your scripts are working fine and they are also easy to understand. My only issue and I guess it comes from animation, is, that my score is raising from 1 - 4 randomly (I am using 4 grapihcs for a gem animation). Any suggestion how to solve this issue?
Why when I duplicate the counter(TMP), then it not count coins in second one?
Can somebody help me please?
thanks, its working
Anyway for me to keep the coins bouncing up and down?
my Text variable is public but in unity it doesn't appears the drag and drop to set Text value
Thanks man!
thanks man
Cannot drag text onto the script slot. just wont let me, not for TMPro or regular text
I have a question. I did everything you did with the coin and for some reason I go right through it. Any ideas? Never mind I put on collision instead of ontrigger 😅
Oh, Congratulation my friend.
Good job and thanks for watching
Maybe because you forget to give the coin a Collider. and if you already put the collider, maybe you forget to check the "Is Trigger" box
I did the same mistake and didnt get it fixed for a while, so thaks for ur comment u helped me find the error
Hey i know this tutorial is relative old but i want to ask about saving this data (coins) and use it later to buy things from the menu?, i want to use player.prefs but everyone says that is bad, (purchase in the app) soo i really want if you can help me and do a tutorial of this! Great video Work for me, keep the great work!
did u find anything for this? I need the same thing that u wrote :)
No, but use player prefs is way more simple
see Save/Load in Unity by Brackeys
he uses binary System which is very easy to make and very secure than player Prefs and Json, XML file
hi, how can I find Layer name with game Object ?
Hi Magma,
Do you want to find a layer using code ?
@@xlaugts151 yes, because I have "Collectable objects and Interactable" and I want create a condition if the player collide a collectable object and if it's a Coin with tag for example. Like I'm a noob
@@Magma-uw7yo You have to have a variable called "public Layermask layer;" you change the value of this on the inspector of the gameObj this script is attached.
Than you can use this to compare.
Have a look on this answers.unity.com/questions/422472/how-can-i-compare-colliders-layer-to-my-layermask.html
see if you can understand it will show u how to compare them
super video can you help me, when i make a build the text doesnt show
Hello friend, the scrips compile me without problem, the coins disappear correctly but it does not count me in the marker, I have everything fine, so it could be
Thank you very much！！！
friend to me because when collecting the last coin the image and text are erased from the screen?
How can i save the score though??
Great tutorial! I do have an issue though, because I use 2 colliders for my player (so it can crouch underthings) the coins sometimes count for 2 instead of 1. Anyone have a suggestion to fix it?
You have to go into the coins script and add the following:
1: add 'public bool trigger = false' inside of the coin class, but outside of the OnTriggerEnter2D method.
2: inside the OnTriggerEnter2D method, inside the if(other.gameObject.CompareTag("Player") statement, add another if condition to if (trigger == false) and execute the ScoreManager inside of that. Remember to set trigger to true so your script only loops once.
This essentially just creates an internal condition that gets checked and prevents any single coin from being counted twice.
@@doctordoge5058 i can't do this please help me
can you help me?
@@doctordoge5058 Thanks a lot. Had trouble with that. checked the unity forums but couldn't find it there
@@doctordoge5058 I watched this video and made the coin system twice because of the duplication of coins. Then i came here and found your comment. Thank you!
The script worked...... until i died and reloaded the scene
so basicaly it works on the first try and if i manualy reload it (pressing play button) but if i use the script to reload the scene it dousent count the coins
thank you!!!
Hi this works but how do i permanently destroy it? Since I'm going from and to different scenes/levels, but whenever I come back to the scene/level the collectable is still there. Is there any way of destroying it forever?
what does it mean by "other.gameObject"?
it means the game object of the thing you are colliding with, in this case "other.gameObject" is the coin, because you are colliding with it
if you only want to use one sprite, you can just use this script. Isn't as visually pleasing, but much easier!
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class CoinRotation : MonoBehaviour
{
private Vector2 rotation;
// Start is called before the first frame update
void Start()
{
rotation = new Vector2(0, 1);
}
// Update is called once per frame
void Update()
{
transform.Rotate(rotation);
}
}
hi thank you so much for the video it helps me a lot :) I just need help on one thing. Why is it when I collect a coin the score becomes 2 instead of 1?
hey mate you might've fixed this by now but this is due to having multiple collision boxes touching the cherry at the same time, to fix it you may have to fiddle around with your characters collision :)
Can i get the game file for my assignment😔
