I have a simple class that contains basic skill attributes for a game. Each player has this skills class attached. I’d like to be able to do basic arithmetic, e.g. playerSkills = playerSkills + 2, and it would go through and add 2 to everything within the class, or perhaps I’d want to add two classes together like playerSkills3 = playerSkills2 + playerSkills1.

I’ve tried using overload operators but I get a stack overflow when calling them?

Any thoughts would be much appreciated.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine.UI;
using UnityEngine.Events;
using System;

[Serializable]
public class PlayerSkillsClass
{

    // Technical
    public float speed;
    public float agility;
    public float jump;
    public float strength;

    public static PlayerSkillsClass operator *(PlayerSkillsClass multiplyThis, PlayerSkillsClass withThis)
    {
        PlayerSkillsClass result = multiplyThis * withThis; //...multiply the 2 Coords
        return result;
    }

    public static PlayerSkillsClass operator *(PlayerSkillsClass multiplyThis, float withThis)
    {
        PlayerSkillsClass result = multiplyThis * withThis; //...multiply the Coord with the float
        return result;
    }
    public static PlayerSkillsClass operator +(PlayerSkillsClass addThis, PlayerSkillsClass withThis)
    {
        PlayerSkillsClass result = addThis + withThis; //...multiply the 2 Coords
        return result;
    }

    public static PlayerSkillsClass operator +(PlayerSkillsClass addThis, float withThis)
    {
        PlayerSkillsClass result = addThis + withThis; //...multiply the Coord with the float
        return result;
    }

}

I get this StackOverflow error, which is repeated for every element in the class i’m adding together:

StackOverflowException: The requested operation caused a stack overflow.
PlayerSkillsClass.op_Addition (PlayerSkillsClass addThis, System.Single withThis) <0x17a6a1af0 + 0x00004> in

Note that this class will have dozens of skills and I’ll be adding and removing skills over time so I don’t want to write manual functions to add/multiple/subtract etc every skill 1 by 1 (I had that before)
