time.deltaTime problems

Unity Engine
1

I am having trouble working out why I cant get time.deltaTime to work, basically my little timer is going down at a very fast speed, should take one hundred seconds, takes about 4. I have tried changing the number I am multiplying with time.deltaTime, but it doesnt effect anything. I am not calling it through ongui so as far as I understand, I should be able to get it to decrease at 1 point per second.

I’ve read the docs, but I think I am missing something simple.

here is my code.

#pragma strict
var airTank : Transform;
var airDistance = 10;
private var airCloseEnough = false;
 
var ourHealth : int = 100;
var maxHealth : int = 100;

var ourAir : int = 100;
var maxAir : int = 100;

function Start () {

}

function Update () 
{
if (ourHealth >= maxHealth)
	{
	ourHealth = maxHealth;
	}
if(ourAir >= maxAir)
	{
	ourAir = maxAir;
	}
ourAir -=1* Time.deltaTime;

if(ourAir <=0)
	{
	print("dead");
	}

if(Vector3.Distance(transform.position, airTank.position) < airDistance)
	    {
	    airCloseEnough = true;
	    }
    if(Vector3.Distance(transform.position, airTank.position) > airDistance)
	    {
	   	airCloseEnough = false;
	    }
	if(airCloseEnough == true)
		{
		ourAir=maxAir;
		}
		
}

You can’t subtract floats from ints and have it work. e.g., 100 (as an int) - .02 = 99. You can only correctly subtract floats from other floats.

What Eric said. If you want to show only the whole number parameter in your GUI, you’d do labelText = Mathf.Floor(ourAir).

Thank you guys, feel a little silly for missing that.
solved!
