temporarily change variable(buff system)

Questions & Answers
1

Hello everyone! Im currently making buff system and occured a problem.
Simple example.

I have stat Damage.
int current = 10;
int max = 15;
int min = 5;

I have Buff,that increases/descreases damage by 6;

1)current(10) + 6 = 15(bigger than max(15), so current equals max)

Buff changed stat by 5,not by 6, so the question is, how can i know what value to return?

What is the best way to save info about actual value that was changed,because everytime making variable isnt great idea, when you change variable above/below max/min, and than need to return that value.

First idea i had, to create a method ChangeValue(string ChangeName,int value) that stores in a list
an object, with name and actual value, so i can access it later, but i dont think its a great way to do that.

Any help is appriaciated. If you are confused, ask, i will try to do my best to explain.

Use Mathf.Clamp.

And example of a function to buff someone:

IEnumerator DamageBuff(int damageBuff, float Duration)
{
    int difference = Mathf.Clamp(current + buff, min, max) - current;
    current += difference;

    yield return new WaitForSeconds(Duration);
    
    current -= difference;
}
