Index Out of Range Exception - can't figure it out
The error is being thrown up in Start() on Line 2
timeRemaining = timeUntilNextAttack[k];
I can't figure this one out.... the index is 10 floats long, assigned in the inspector.

Best Answer
Are you filling in the values of timeUntilNextattack in the inspector? You could fill your array in Start() like so for testing:
timeUntilNextAttack = new float[]{10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
First off, thanks so much for the fast response - wasn't expecting anything until tomorrow!
When I put this line of code directly above the problem in Start(), it eli$$anonymous$$ates that issue and then creates a new error at line 65.
Not sure what that means about the original issue?
NullReferenceException: Object reference not set to an instance of an object
Game$$anonymous$$anager.Countdown()(at Assets/Resources/Game$$anonymous$$anager.cs:173)
You're adding ints to a string without converting ToString(). That may be causing an issue, but as far as the null issue goes, make sure NOTHING is null, EVERYTHING has been assigned a value. days, dayText, hours, hourText, and so on.
timerCountdown.text =
days.ToString()
+daytext
+hours.ToString()
+hourtext
+$$anonymous$$utes.ToString()
+$$anonymous$$utetext
+seconds.ToString()
+secondtext;
Have you initialized timerCountdown or is it unassigned? In my opinion this is the case of exception.
