Questions & Answers

Hi,

Ive got a score that i want to increase at a certain speed so that if i say have a score 0 than add 100 to it, the score wont immediately show 100 but tick up for 0 to 100.

Any ideas on how to do this?

Using a Coroutine comes to mind. You can wait for a time, then ‘tick’ the score. For example:

//this example increments the score by 1 every 1 second
public class ScoreTicker : MonoBehaviour
{
	//this is what our score should be like after we're done 'ticking'
	public int TargetScore;

	//this is the value representing our 'real' score at any given time
	public int CurrentScore;

	//this is how much we increment the score every tick - set in the inspector
	public int ScorePerTick = 1;

	//this is how long we wait between ticks - set in the inspector
	public float TickInterval = 1;

	void Start()
	{
		//in this case, as in most cases, I start the coroutine using it's name, so it can be stopped later
		StartCoroutine("Ticker");
	}

	//raise the score target
	public void AddScore(int score)
	{
		TargetScore += score;
	}

	//this will increment the CurrentScore towards the TargetScore over time
	public IEnumerator Ticker()
	{
		//this loop will run forever so you can just call AddScore and the ticker will continue automatically
		while (true)
		{
			//we don't want to increment CurrentScore to infinity, so we only do it if it's lower than TargetScore
			if (CurrentScore < TargetScore)
			{
				CurrentScore += ScorePerTick;

				//this is a 'safety net' to ensure we never exceed our TargetScore
				if (CurrentScore > TargetScore)
				{
					CurrentScore = TargetScore;
				}
			}

			//wait for some time before incrementing again
			yield return new WaitForSeconds(TickInterval);
		}
	}
}
