Choosing Random Values

[Emera]

I am trying to make a system, just for testing purposes that picks out a random number or word from an array and echo it.
Example;

PHP Code:

//#CLIENTSIDE
function onCreated() {
  //Define array
  this.array = {"One", "Two", "Three", "For"};
}

function onWeaponFired() {
  //Do stuff here
  echo(result);
} 


I want it to randomly select either of the values in the array, and echo the result. Any ideas?

If your array is guaranteed to have more than 1 element:

echo(randomstring(this.array));

will do exactly what you want to. You can also do:

temp.result = this.array[int(random(0, this.array.size()))];

Thank you very much

I would avoid randomstring entirely, it's only going to lead to problems in the future when somebody changes your script so that it's not guaranteed to have at least two elements.

So using;

NPC Code:

---

temp.result = this.array[int(random(0, this.array.size()))];

---

Is my best bet? Can you explain this to me in further detail please? What does the [int(random(0,this.array.size()))]; bit mean?

int(value) - Converts the value to an integer (rounded). I.e: int(2.5) - returns 2
random(a, b) - Returns a random value between a and b. It'll never equal b though.
array[i] - The element in the array.

It basically generates a valid random index in the array.

PHP Code:

temp.ind = int(random(0, this.array.size()));
temp.result = this.array[temp.ind];

Ah ok. Thank you

Uh, what?

Try running this a 10 or 20 times:

PHP Code:

function onCreated() {
  temp.a = {"a"};
  echo(randomstring(temp.a));
} 


Should echo "a" every time but it doesn't.

What the hell!? That's shady.

Ok will fix that behaviour of randomstring(), it was originally not made for getting arrays as input.

Can you add a random() to TGraalVar (or whatever the main class is) so we can retrieve random elements or characters from arrays and strings. I.e:

"abcdefg".random() - can return "a" or "b" or etc.
{1,2,3,4}.random() - can return 1, 2, or etc.
