2D game Score based on Time

Hello everybody,
I have a small problem, because im pretty new to unity.
I have this 2d game where i play as a ball that can roll to the left and right.
Now i want to add a Score that goes up every second.
I already have a Ui canvas and text so on the play screen it says "0"
where do i need to make a script and what goes into the script so my timer works?
thankful for every bit of help.

kind regards

 

Update or a coroutine. Update is easier to understand for someone new to Unity, but coroutine might be the better tool. Example using Update below (untested because I just wrote it directly into the forum, so sorry if I made a typo).

Code (csharp):

1. public Text ScoreTextComponent;  //Assign this in the inspector
2. private int score = 0;  //current score as an integer
3. private float secondTimer = 0f;    //timer for counting to 1 second
4.  
5. void Update()
6. {
7.     secondTimer = secondTimer + Time.deltaTime;
8.     if (secondTimer >= 1f)
9.     {
10.         addScore();
11.         secondTimer = secondTimer - 1f;
12.     }
13. }
14.  
15. private void addScore()
16. {
17.     score++;
18.     ScoreTextComponent.text = score.ToString();
19. }

 

Thank you so much ! that worked fine and was easy to understand! Appreciatet !
