Multiplying a feed after kill

Questions & Answers
1

I have a score feed, which displays a text that says “15+” when ever i kill an enemy, but the problem is, if i shoot multiple enemies in a small time range it will just show “15+” throughout it, so it would be hard to distinguish between each kill. I want it to double whenever i get multiple kills within a certain time range (i know it says multiply in the title, but it looks better.). Here is an example from CoD: best cod feeds ever. - YouTube

I’ve searched it up, but i still can’t find a good solution, i’ve been pondering for a while now.

XP feed code, that pops up a text (saying 15+) whenever i kill someone:

 public class XpFeed : MonoBehaviour {

    public float showtime;
    Text text;
    public int xpFeed;

    void Awake()
    {
        // Set up the reference.
        text = GetComponent<Text>();

        // Reset the score.
    }

    void Update()
    {
        // Set the displayed text to be the word "Score" followed by the score value.
        text.text = "+" + xpFeed + "xp";
    }

    public void getFeed()
    {
        StopCoroutine("showfeed");
        text.enabled = true;
        StartCoroutine("showfeed");
    }

    public IEnumerator showfeed()
    {
        yield return new WaitForSeconds(showtime);
        text.enabled = false;
    }
}

And enemy AI code:

public class AIHealth : MonoBehaviour
{

    public int xpValue = 15;
    public GameObject xpfeed;
    
    void Awake()
    {        
        xpfeed = GameObject.Find("XPFeed");
    }

    void Death()
    {
        XPManager.curXp += xpValue;
        xpfeed.GetComponent<XpFeed>().getFeed();
    }
}

You can check youtube for ´scrolling combat text tutorial´ and do a similar solution to that if you are having a lot of messages incoming.

In my game, it was much slower and I could never have more than 2 messages at a time, so I did an easier solution. I had two text boxes, Primary and Secondary with primary slightly below secondary.

then I did

If ( primary is active in hierarchy)
     put text in secondary
else 
    put text in primary.

Make a timer.

Each time you get a kill set timer at 3sec or something.

Check if timer is more than 0 and if it is add 15 to your xpfeed variable.

If timer is 0 do your regular code.
