add spawned GameObjects in an array C#
Hello,
I wanna keep the GameObjects (Clones) I instantiate in an array. I tried it like this:
//C#
public Transform Object;
public static GameObject[] SpawnedObjects;
public static int arrayPosition = 0;
void Start(){
SpawnedObjects = new GameObject[430];
arrayPosition = 0;
}
//....
//In a function
print("ArrayPosition: "+arrayPosition);
SpawnedObjects[arrayPosition] = ((Instantiate(Object, Position, Quaternion.Euler (0f,0f,0f))) as GameObject);
print ("Object im Array: "+SpawnedObjects[arrayPosition]);
arrayPosition = arrayPosition + 1;
Later I want to be able to destroy the last GameObject added to the array in another function like this:
if(SpawnedObjects[arrayPosition-1]){
Destroy(SpawnedObjects[arrayPosition-1]);
}
The spawning of the GameObjects is working but my array is always empty. Does anyone know what I´m doing wrong? All examples I found in the internet were showing the same way.
Thank you in advance.

First of all, why is the array static? You don't need static variables here.
Secondly, you are trying to store a Transform
as a GameObject
. Therefore the cast always returns null
.
Either change the type of
Object
toTransform
(by the way don't useObject
as a variable name, becauseObject
is also a reserved name for a type).or use an array of
Transform
instead of an array ofGameObject
or retrieve the GameObject from the instantiated transform:
(Instantiate(Object, Position, Quaternion.identity) as Transform).gameObject;
edit: The need to change a value from another script is not a valid argument for using static variables. There are several ways to access a variable from another script.
For example if your script is on a unique GameObject, you can do:
MyScriptName script = (MyScriptName) Object.FindObjectOfType(typeof(MyScriptName));
script.publicVariable = value;
If the script is just another component on the same Gameobject, it is even easier:
MyScriptName script = GetComponent<MyScriptName>();
script.publicVariable = value;
Thank you for your fast response.
$$anonymous$$y array and the variable arrayPosition are static because the function to destroy the Last added GameObject is in another class.
In the original code the name of the variable isn´t Object. I´m sorry I made the mistake here.
I changed my code as you recommand to:
(Instantiate(Object, Position, Quaternion.identity) as Transform).gameObject;
and it is working now.
Thank you for your help.
