Regeneration using Time.deltaTime

Question

I'm trying to regenerate stamina at a rate of 1 per second using Time.deltaTime, however this doesn't do anything (My 'current stamina' doesn't change at all). I've done some looking around and I have tried Time.fixedDeltaTime. Also tried Time.time, but that just regenerated all my stamina in under a second.

Here is my code:

var max_stamina : int = 100;
var cur_stamina : int;
var staminaRegenRate : int = 1;

function Update(){
    //regen
    if(cur_stamina < max_stamina){
        cur_stamina += staminaRegenRate * Time.deltaTime;
        Debug.Log("Second has passed");
    }
}

What am I doing wrong?

Answer 1

I guess since you are declaring the variables as integer, when you do cur_stamina += staminaRegenRate * Time.deltaTime; it is rounded to the nearest integer, effectively not changing its value.

Declare them as floats or doubles (and be more careful with data types!).
