Subtracting variable amount over time?
How can I distract a variable over time? For example:
var amount : int = 10;
Every second (declared in a variable so I can change the speed) the amount is subtracted by 1. Can anyone help me?

very simple, please learn about Invoke() and InvokeRepeating()
many beginner articles on this at unityGEMS.com
Here's a simple way to do it:
var amount : int = 10;
in your Start() routine...
Invoke( "removeOneSecond", 1.0 );
write a simple routine like this:
function removeOneSecond()
{
if ( removeOneSecond < 0 ) return;
removeOneSecond = removeOneSecond - 1;
Debug.Log("removeOneSecond is now ... " + removeOneSecond);
Invoke( "removeOneSecond", 1.0 );
}
OK? So it's that easy. Alternately you could use InvokeRepeating() and then when it is less than zero, CancelInvoke(). Cheers.
