returning random strings from a list

How would I make a list of strings and have the script choose one at random?

list data =[
"something",
"something else",
"stuff",
"bob",
"jay z"];

default
{
state_entery()
{
llOwnerSay(llList2String(data,llFloor(llFrand(4))));
}
}

or something like that

kk thanks

Here is an interesting thread you make want to look at:

/54/05/207690/1.html

Why use llFloor instead of typecasting to an integer? Also, doesn't llFrand return values [0, input)? So by putting in 4, you'll never retrieve the last list element.

cause i wrote it while not inworld, off the top of my head in like 3 seconds



llFrand does, theres 5 elements 0-4, but im sure it doesnt work like that, that would be too easy ...

edit it doesnt do 0-4 it does (while x < 4) which is a silly quirk i forgot about, so yea it needs to be 5

also see above

that script was a quick nudge in the right direction, nothing more

list data = ["Aniam", "Osgeld", "Tyken", "Jesse"];

default
{
	touch_start(integer total_number)
	{
		integer list_length = llGetListLength(data);
		integer random = (integer)llFrand(list_length);
		llSay(0, llList2String(data, random) + " is the Ruler of the forum!");
	}
}

OMG! It's ME!!!!!!! I am the Ruler of the forum!!!!!
Shucks! Now Osgeld is.......................................

Haha, thanks jesse. You're always helpin' me out.

out of practice, cause osgeld has been writing lua and php (not connected) for the last 5 months and not lsl

so jesse you can have the title of king, for now, but i shall return!

is that better than

list someList =["1", "2", "3", "4", "5", "6"];

llSay( 0, "die rolled: " + llList2String( llListRandomize( someList, 1), 0 ) );

Good question.

Let's compare what they have to do:

list data = ["Aniam", "Osgeld", "Tyken", "Jesse"];
integer list_length;

default
{
	state_entry()
	{
		list_length = llGetListLength(data);//No use in making it check list length everytime
	}
	touch_start(integer total_number)
	{
		integer random = (integer)llFrand(list_length);
		llSay(0, llList2String(data, random) + " is the Ruler of the forum!");
	}
}

Makes the simulator do this with every touch:

"*** touch_start(1)
Frand(4.00000)=1.85173216920892
List2String([Aniam,Osgeld,Tyken,Jesse],1)=Osgeld"

list data = ["Aniam", "Osgeld", "Tyken", "Jesse"];

default
{
	touch_start(integer total_number)
	{
		data = llListRandomize(data,1);
		llSay(0, llList2String(data, 0) + " is the Ruler of the forum!");
	}
}

The simulator does this:
*** touch_start(1)
ListRandomize([Aniam,Osgeld,Tyken,Jesse],1)=[Jesse,Osgeld,Aniam,Tyken]
List2String([Jesse,Osgeld,Aniam,Tyken],0)=Jesse"

So both do a good job. And with a short list probably equal But as the size of the list grows............Option one would be better because you are not having to manipulate the list itslf, which can be expensive when it comes to long lists.

A more clear example would be the link I posted above and compare what has to happen to get a random output:

And this, my friends is why the more advanced scripters who have poo poo'd LSLEditor in the past really need to take a second look at it. You can see what is actually happening as the script runs. Plus you can also now use lslint as a plugin with it.
