I have two script.
Script1 Script2
In Script1 i declared a arraylist it contains value 2, 4, 6, etc...
public static ArrayList aArray= new ArrayList();
function update(){
if(bool1)
{
aArray.Add(i);
}
}
I have to check a value 5 exist in arraylist from Script2.
if value exists i have to get its key.
How to get it?
First, i would recommand using a generic List<T> instead of the non-generic ArrayList, which enables you to specify the type of objects that go into that list (for better type safety).
Also, declaring a variable readonly prevents you from accidently overwriting it, which is often the case with Lists (after all, you can always just Clear them):
public static readonly List<int> items = new List<int>();
Now to answer your actual question, if you want to check if a value exists in the list, you can use the method Contains.
To check if the value does not exist, just put an ! in front of the expression:
if (!Script1.items.Contains(i)) {
// This will only execute if the list does not contain i.
items.Add(i);
}
Try using Contains. This code will detect if you have already the value in the ArrayList and will stop code from adding it a second time.
public static ArrayList aArray= new ArrayList();
function update()
{
if(aArray.Contains(i)==false)
{
aArray.Add(i);
}
}
If you want to remove a value it is just as easy as aArray.Remove(i)
if I understood correctly, Script1 is in your camera, and Script2 is in a Character. For the sake of this example we'll call them MainCamera and Character respectively.
Now, unless I understood wrong, you're trying to access an Array in Script1 from Script2. While the other answers are very much correct, unity3D has a bit of a workaround needed to access it.
Anyway, within Script2 use this:
if(GameObject.Find("MainCamera").GetComponent<Script1>().aArray.Contains(5))
{
//Do your code here
}
