Warning:

Assets/Scripts/MainMenu.cs(159,29): warning CS0472: The result of comparing value type `System.Collections.Generic.List<float>.this[int]' with null is `true'

Code:

what I want to achieve is:

	void EventLogF(){
		for (int i=EventMessages.Count-4; i<EventMessages.Count; i++) {
			if (EventTimes *!= null){*

_ if (EventTimes > Time.time-SecondsToDisapear){_
_ GUILayout.Label( EventMessages );
* }
 else {
 EventMessages.RemoveAt(i);
 EventTimes.RemoveAt(i);
 }
 }
 }
 }
and yes I do get null error because it returns true, … why is that?
my before code was:
 void EventLogF(){
 int num = 3;
 for (int i=EventMessages.Count-1; i>=0; i–) {
 num --;
if (EventTimes > Time.time-SecondsToDisapear){
GUILayout.Label( EventMessages );
}
else {
EventMessages.RemoveAt(i);
EventTimes.RemoveAt(i);
}*_

* if (num == 0){*
* break;*
* }*
* }*
* }*
but problem was the new messages were on top instead of bottom.

if (EventTimes != null)
You are comparing a float to null, and apparently it will result in true. It should result in not letting you do that. Compare a float to a float, like 0f or -1f or something.

Type float can not be null, therefore the condition"EventTimes *!= null" will always be true.*
The default value of type float is 0.0f.
You could use a Float which can be null, or you could use an invalid value like -1.0f as dummy data.
