How do I find the position of an element in an array?
Hey guys.
I'm having a bit of trouble with finding the position of a string in an array using JScript. Whats the best way to go about this?
I know what the strings are but I need to know what the positions of them are.
Cheers.
This is a Javascript question, not a Unity one.
The question seems relevant here because javascript or a variation of it is a coding language used in Unity. Not to mention that Unity seems to have its own take on arrays.
Unity uses .NET/$$anonymous$$ono arrays, nothing unique. (Aside from the Array class, which is an implementation that's the same as web Javascript arrays.)
Thanks for clearing that up. $$anonymous$$y main point there was that the question isn't irrelevant as the answer will help other unity users.
The problem is that you could say that about all general program$$anonymous$$g questions, since Unity uses program$$anonymous$$g. But general questions would be better served elsewhere since they aren't specific to Unity; that way we can focus on Unity-only questions here.
for(int i = 0; i < array.Length; i++)
{
Debug.Log("The element in index " + i + " is " + array[i];
}
I think that should about do it.
Loop through the array.
Thats what I'm doing, looping through the array to find the string I want but I need to know the index of that string.
@Tides: if you're already looping, then you have the index. That's what the loop index tells you.
You can also use the FindIndex and/or IndexOf methods of the Array class (.NET arrays, not UnityScript arrays), but those methods are specialized, so manually looping through your array is generally faster.
Here is my example, hope this helps someone: It's a rough snippet of something I'm working on.
public string[][] pass = new string[2][];
// define the array somewhere like:
pass[0] = new string[] { "ant", "bug" };
pass[1] = new string[] { "dog", "boy" };
// check for what's in the list
void checkPassword(string k)
{
int i = 0;
int l = pass[0].Lenth;
for(i=0; i < l; i++) // don't define vars in your for() it's slow
{
if(pass[0][i] == k) { print("index --> " + i); }
}
}
