Timer counting problem

I’d like to show some text when the player kills e.g. 3, 4, or 5 enemies in a given time (in Unity3d).

I have a timer (comboTimer) which is in my PlayerControl-script that starts when an enemy gets shot by the player. When the timer starts a counter (comboCounter) gets increased everytime an enemy gets shot by the player. The other script (EnemyControl) controls the way how the appropriate text gets displayed when the kill-counter (comboCounter) reaches a certain value (e.g. 3 kills = “Combo x3”). This should be done within the timer’s value.

The problem is the text that gets shown is in almost most cases 3 kills (“Combo x3”). I never reach 4 or 5 kills within the timer’s value even when I increase the waitTime to e.g. 5 or 10 seconds. There is a bug within the logic but can’t find it. Can someone help me, please?

This is the Timer of my PlayerControl-script:

Code (CSharp):

1. public static bool comboTimerRunning = false;
2. public static int comboCounter;
3.  
4. float comboWaitTime = 1f;//1.0 Sekunden
5. float comboTimer;
6.  
7. public void ComboTimer() {
8.    comboTimer += Time.deltaTime;
9.    if (comboTimer > comboWaitTime)
10.    {
11.        ResetComboTimer();
12.    }
13. }
14.  
15. public void ResetComboTimer () {
16.    comboTimer = 0f;
17.    comboTimerRunning = false;
18.    comboCounter = 0;
19. }

This is the script that controls the handling of the displayed text (EnemyControl):

Code (CSharp):

1. if (!PlayerControl.comboTimerRunning) {
2.        PlayerControl.comboTimerRunning = true;
3. }
4. PlayerControl.comboCounter++;
5. if (PlayerControl.comboCounter >= 3) {
6.    if (PlayerControl.comboCounter == 3) {
7.            comboTxtObj.GetComponent<ComboTxt>().ShowComboText("Combo x3");
8.    } else if (PlayerControl.comboCounter == 4) {
9.            comboTxtObj.GetComponent<ComboTxt>().ShowComboText("Awesome");
10.    } else if (PlayerControl.comboCounter >= 5) {
11.            comboTxtObj.GetComponent<ComboTxt>().ShowComboText("Mega-Kill");
12.    }
13.    PlayerControl.comboTimerRunning = false;
14. }

 

When are you calling ComboTimer()? When is the second piece of code (in your EnemyControl) called?
