How to read my score in another script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class ScoreManager : MonoBehaviour
7. {
8.  
9.     private Text myText;
10.     private long score;
11.  
12.     void Start()
13.     {
14.         myText = this.GetComponent<Text> ();
15.         UpDateScore ();
16.     }
17.  
18.     public void AddScore(int addToScore)
19.     {
20.         score += addToScore;
21.         UpDateScore ();
22.     }
23.  
24.     public void SubtractScore(int addToScore)
25.     {
26.         score -= addToScore;
27.         if (score < 0)
28.         {
29.             score = 0;
30.         }
31.         UpDateScore ();
32.     }
33.  
34.     private void UpDateScore()
35.     {
36.         myText.text = "Score - " + score;
37.     }
38.  
39.      
40. }
41.  

in public void AddScore….how do I read and add some points to it

 

Just set the score to public and get a reference to this instance of the script. Usually that is done with GetComponent, or established using a field with the inspector.

 

don't want to do it that way

 

If you want to return it from AddScore you just do it like this.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class ScoreManager : MonoBehaviour
7. {
8.  
9.     private Text myText;
10.     private long score;
11.  
12.     void Start()
13.     {
14.         myText = this.GetComponent<Text> ();
15.         UpDateScore ();
16.     }
17.  
18.     public long AddScore(int addToScore)
19.     {
20.         score += addToScore;
21.         UpDateScore ();
22.         return score;
23.     }
24.  
25.     public void SubtractScore(int addToScore)
26.     {
27.         score -= addToScore;
28.         if (score < 0)
29.         {
30.             score = 0;
31.         }
32.         UpDateScore ();
33.     }
34.  
35.     private void UpDateScore()
36.     {
37.         myText.text = "Score - " + score;  
38.     }
39.  
40.      
41. }
42.  

 

Your code is fine, when you send an amount to AddScore, it will do that and then update the text... IS this not what you want?

Unless there is some issue with adding a long and and int, in which you would add (long) to the value to convert it.. e.g. (long)amount

Also,
Here is a tidy version of your code. You can send through add and subtract in the same function just by calling a negative number instead for lowering the score.

50 += -25 would equal 25 see.

Code (CSharp):

1. public class ScoreManager : MonoBehaviour
2. {
3.     private Text myText;
4.     private long score;
5.     void Start()
6.     {
7.         myText = this.GetComponent<Text> ();
8.         UpDateScoreText();
9.     }
10.  
11.     public void AmendScore(int amount)
12.     {
13.         score += addToScore;
14. score = mathF.clamp(0, int.MaxValue);
15.         UpDateScoreText();
16.     }
17.     private void UpDateScoreText()
18.     {
19.         myText.text = "Score - " + score;
20.     }    
21. }

 

You can use a singleton and make everything static so that you don’t actually need an instance of this object to modify the score. Then have your text ui object do a check if the score has changed each frame.

 

This is all fine and thanks...but my question is still unanswered....how do I send addToScore = 10; to the AddScore.

 

It’s not unanswered: you simply make your variables and method static.

 

AddScore(10);
I'm sure this cant be the question your asking, its way to easy?
If it isn't, in your next post can you try and be more clear about what you want, and use some terminology.

 

I'll try this again…...How do I access this score manager script from another script...say a enemy script....what line of code do I use to add points to the score manager script?

 

Your message come across a quite arrogant dude!
I'm still gonna help you though because I do this for me



Every script is publicly accessible. The content may not be however. Here is an example

Code (CSharp):

1. public class ScoreManager
2. {
3.     public void AddScore();
4. }
5.  
6. // From another Script you can access AddScore like this..
7. ScoreManager _scoreManager = new ScoreManager();
8. _scoreManager.AddScore();
9. //Note this creates a new instance and is not referencing the script you have attached to an object in the scene.
10.  
11.  
12. public class ScoreManager
13. {
14.     public static void AddScore();
15. }
16.  
17. //Note AddScore is now static.
18. //This means if you have this script attached to several object, and call add score then it will run on all objects.
19. //Used like this
20. ScoreManager.AddScore();

 

Sorry if I came across that way...i'm new at this and find it hard to explain things....BTW i'm 70 so a little break please.

 

And it helps me!
