Question Get Reference in Type Class?

I have a type "Task" and from there i need to be able to edit a variable "pointCount" in my gamemanager.
If you want to see my attempt at making this work here it is:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Manager : MonoBehaviour
6. {
7.     public int taskCount;
8.     public float pointCount;
9.     public Task task;
10.     void Start()
11.     {
12.         task = new Task(5f);
13.     }
14.     public void UpdatePoints(float pointdiff)
15.     {
16.         pointCount += pointdiff;
17.     }
18. }
19. [System.Serializable]
20. public class Task
21. {
22.     float points;
23.     public Task(float ipoints)
24.     {
25.         this.points = ipoints;
26.         UpdatePoints(ipoints);
27.     }
28. }

 

I'm assuming it's the "points" variable you want to edit outside of the Task object?

Either make it a public field...

public float points;

...Or a public auto-property:

public float Points { get; set; }

Edit, OP was updated with more info:

If "points" is a constant value, you could give it a get-only public property and just update the value of "pointCount" in your Manager script when you instantiate a new Task:

Code (CSharp):

1. public class Task {
2.    private float points;
3.  
4.    public Task(float points) {
5.       this.points = points;
6.    }
7.  
8.    public float Points => points;
9. }

Code (CSharp):

1. public class Manager : MonoBehaviour {
2.    public Task task;
3.    public float pointCount;
4.  
5.    void Start() {
6.       task = new Task(5f);
7.       pointCount += task.Points;
8.    }
9. }

 

You could use a custom eventhandler to do this.

Code (csharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public delegate void UpdatePointsEventHandler(float points);
6.  
7. public class Manager : MonoBehaviour
8. {
9.     public int taskCount;
10.     public float pointCount;
11.     public Task task;
12.     void Start()
13.     {
14.         task = new Task(5f, UpdatePoints);
15.     }
16.     public void UpdatePoints(float pointdiff)
17.     {
18.         pointCount += pointdiff;
19.     }
20. }
21.  
22. [System.Serializable]
23. public class Task
24. {
25.     float points;
26.     public event UpdatePointsEventHandler onUpdatePoints;
27.  
28.     public Task(float ipoints, UpdatePointsEventHandler onUpdatePoints)
29.     {
30.         this.points = ipoints;
31.  
32.         this.onUpdatePoints += onUpdatePoints;
33.  
34.         if(onUpdatePoints != null)
35.             onUpdatePoints(ipoints);
36.     }
37. }

 

Thanks for this! i interpreted a tiny snippet from your code to suit my needs more easily by passing the manager reference through the constructor. GENIUS!
public Task(float ipoints, Manager imanager)
{
this.points = ipoints;
this.manager = imanager;
manager.UpdatePoints(ipoints);
}
