Problems with gameobject array

Questions & Answers
1

I have an array of game objects declared as:

public GameObject[] lifeMarkers;

I want to truncate the array by chopping off the last element.
I’ve tried Pop() and array.length = array.Length - 1 but I get this error each time:

Assets/GameController.cs(86,37): error CS1061: Type `UnityEngine.GameObject[]' does not contain a definition for `length' and no extension method `length' of type `UnityEngine.GameObject[]' could be found (are you missing a using directive or an assembly reference?)

I got both those commands from the unity script reference. Any advice?

Changing the size of arrays at runetime is not very efficient, as it involves a lot of memory copying. Consider other alternatives such as using a List, a LinkedList, or a queue. All of those (I think) contain a method of removing the last element.

If you need to change the size of an array at runtime, then try something akin to

`
int newLength = lifeMarkers.Length-1;

newLifeMarkers = new GameObject[newLength]

System.Array.Copy(lifeMarkers,newLifeMarkers,newLength);

lifeMarkers = newLifeMarkers;

`

Or alternatively, allocate enough memory (indexes) into your array and keep an int to keep track of the current last element.
