Pass by reference on button clicks C#

Hey guys I have a quick question that I can't figure out.

I want to combine the following methods into one method

Code (CSharp):

1. public void OnHealthButtonClick()
2.     {
3.         hpModifier++;
4.         unusedSkillPoints--;
5.  
6.         if (unusedSkillPoints == 0)
7.         {
8.             skillPanelReadyButton.interactable = true;
9.         }
10.     }
11.  
12.     public void OnAttackSpeedButtonClick()
13.     {
14.         attackSpeedModifier++;
15.         unusedSkillPoints--;
16.  
17.         if (unusedSkillPoints == 0)
18.         {
19.             skillPanelReadyButton.interactable = true;
20.         }
21.     }
22.  
23.     public void OnDamageButtonClick()
24.     {
25.         damageModifier++;
26.         unusedSkillPoints--;
27.  
28.         if (unusedSkillPoints == 0)
29.         {
30.             skillPanelReadyButton.interactable = true;
31.         }
32.     }
33.  
34.     public void OnMoveSpeedButtonClick()
35.     {
36.         moveSpeedModifier++;
37.         unusedSkillPoints--;
38.  
39.         if (unusedSkillPoints == 0)
40.         {
41.             skillPanelReadyButton.interactable = true;
42.         }
43.     }

And I want them to basically be this method that I can put on each button's OnClick section in the inspector.

Code (CSharp):

1. public void OnStatButtonClick(ref int modifier)
2.     {
3.         modifier++;
4.         unusedSkillPoints--;
5.  
6.         if (unusedSkillPoints == 0)
7.         {
8.             skillPanelReadyButton.interactable = true;
9.         }
10.     }

Then I want to just set which modifier to change in the inspector. Is this possible?

Thanks,
Tucker

 

UnityEvents can't have parameters that are references to primitives like that, no.

 

One thing you could do is have a dictionary with an enum key and an int value.

Then you could have your method but it would simply take an enum and not by reference.

 

You could always wrap the int in its own class that could be passed by reference. I believe this is called boxing.

Reflection is also a possibility, if you need ultimate flexibility.

 

OK thanks for the help and suggestions guys.
