Randomly Select String from Array
I've got a list of strings contained within a public void, yet any method I use to randomly select one of the strings does not work. Here's the code:
public void rng () {
ArrayList word = new ArrayList();
word.Add("One");
word.Add("Two");
word.Add("Three");
word.Add("Four");
word.Add("Five");
word.Add("Six");
word.Add("Seven");
word.Add("Eight");
word.Add("Nine");
word.Add("Ten");
}
void Start () {
ans = rng[Random.Range(0, rng.Length)];
}
Does anyone have a way I can fix this so the code will assign a string from the list to the variable "ans"? Thanks in advance, -MrFodds
word needs to be a global variable. Call the function to populate the array. Then pick a random position in the array word :
public void rng () {
word = new ArrayList();
word.Add("One");
word.Add("Two");
word.Add("Three");
word.Add("Four");
word.Add("Five");
word.Add("Six");
word.Add("Seven");
word.Add("Eight");
word.Add("Nine");
word.Add("Ten");
}
ArrayList word;
void Start () {
rng();
ans = word[Random.Range(0, word.Length)];
}
I edited the comment. word needs to be a global variable.
I don't use ArrayLists, but this is a great reference : http://wiki.unity3d.com/index.php?title=Which_$$anonymous$$ind_Of_Array_Or_Collection_Should_I_Use?#ArrayLists
So use word.Count
It's not. It's because ArrayList converts everything you put in it to the base type object. To use anything from it, you have to cast it to the correct type. This is the major reason you don't want to use ArrayList, and use generic lists ins$$anonymous$$d.
I'd always recommend using a generic list over ArrayList (that's List. They're much safer to use, since they have an associated type.
You need to use generic tags. C#'s built-in List class allows you to define a type for the list, which means you don't need to cast anything, and allows you to keep the typing of your objects while they're in the list. I unfortunately can't directly post an example because the comment system removes anything inside triangular brackets.
