Question by Tyler 2 · Nov 26, 2010 at 10:35 PM · variablevaluedecrease

Variable that decreases after a certain amount of time?

Hello. How can I have a static variable decrease at a set rate after a period of inactivity? Ex: A value increases when a player shoots an enemy. If the player has shot no enemies for 5 seconds, the value will start to decrease at a rate of 2 every 3 seconds. Thanks

Something like this -

var lastScoreTime : float; var score : float; var pointLossPerSecond : float = 0.67; var penaltyTime : float = 0.5;

function Score( amnt : int ) { score += amnt; lastScoreTime = Time.time; }

function Update() { if ( Time.time - lastScoreTime > penaltyTime ) score -= Time.deltaTime * pointLossPerSecond; score = Mathf.Max(0, score); }

Humm, try something like this:

static var Score : int = 20; static var KilledEnemy : boolean = false;

 function Update()
 {
    if(KilledEnemy == false){
       Invoke("Timer", 5);
    }
 }

 function Timer()
 {
    Score =-2;
    yield WaitForSeconds(3);
    Score =-2;
    return;
 }

Hasn't been tested, in a hurry - sorry.

That will invoke Timer every frame, and every Timer call will reduce the score by exactly 4.
