Call function once in a while after a condition is met?

Questions & Answers

I want to grant the player one extra life every 10000 points.

void extraLife (){
    PlayerPrefs.SetInt ("Lives", PlayerPrefs.GetInt("Lives") + 1);
}

I keep the player’s score in PlayerPrefs.Getint ("Score");

The player’s score doesn’t increase in steady amounts - it increases in 10s, 200s and 500s.

How do I call the function extraLife() once the 10,000 limit has been crossed, but only once, until the limit is broken again?

For example, the player has 10,210 points. I want to grant him a life. When he reaches 20,000, I want to grant him another life. But the player won’t have exactly 20,000 points, but a bit more. How do I do this?

Well you could do something of those:

  1. If your progression is linear then just add another int variable and a constant of progression. How will that work? Well just when each time score increases check like this:

    if (score >= progressionConstant * currentProgressionInteger)
    {
    currentProgressionInteger++;
    extraLife();
    }

Also don’t forget to save that currentProgressionInteger.

2)If non-linear. Then you might have to add a for example a List or array of “progression bases” for which your player will be rewarded, and then do almost the very same thing (except that this time progressionConstant will be replaced with a List/Array/Dictionary/…):

if (score >= progressionList[currentProgressionInteger])
{
    currentProgressionInteger++;
    extraLife();
}
