Add 1 point when GameObject is in scene

My game spawns traffic cars into a scene.
I want to make it so that if a traffic car with the tag "CarPoints" is spawned, it adds a point
Here is my script:

Code (CSharp):

1.     [SerializeField]
2.     private Text scoreText;
3.     public GameObject[] cars;
4.     void Update()
5.     {
6.         cars = GameObject.FindGameObjectsWithTag("CarPoints");
7.  
8.         foreach (GameObject car in cars)
9.         {
10.             Score = Score + 1;
11.  
12.         }
13.     }
14.     private int score;
15.  
16.     public int Score
17.     {
18.         get { return score; }
19.         set
20.         {
21.             score = value;
22.             scoreText.text = "Cars Hit: " + score.ToString();
23.         }
24.     }
25.  
26.     private void Awake()
27.     {
28.         Score = 0;
29.     }

right now whenever I start the scene, the Score value just keeps going up
anyone know how to do this properly?

 

well, what you do is basically search nonStop in the "Update" loop for GameObjects with a certain "Tag",

and whenever any car is found, your points go up, what you want to do is to have a spawner which handles that,
not in an update loop but by Events or any calls,

I mean, how many cars do you want to spawn in total?
do the cars have spawn points, or is it random?
when do you want to spawn more cars additionally?

 

I figured it out!
I decided to reverse the system and use unity's messaging system
it now sends a message from an empty gameobject parented to the car prefabs to any scoremanager objects and then sets itself inactive so that it only sends 1 extra point

It may be a little janky, but it works
shame you can't delete forum posts afterwards

 

I don't sure that I understand right, you need to add point when car with point spawned.
If so, you can do next:
Attach to car with point prefab script in start function call UnityEvent onCarWithPointSpawn, in your scores script listen for this event and do what you want(add scores, update UI and so on)
