Need Script to whisper random messages

I have a whisper text that works when you touch the prim. I need to be able to have the prim, when touched, whisper a random message.

string message = "Turn to the Left";

default
{
touch_start(integer total_number)
{
llWhisper(0, message);
}
}

Im not a great scripter myself but I adapted a question from a couple of posts down to answer yours I think this will work but havnt tested it yet.

list message = ["turn left", "turn right", "up", "down", "all around", ];

default
{
touch_start(integer touchy)
{
message = llListRandomize(message, 1);
llWhisper(0,llList2String(message,0));//returns 1st message in list
}
}

UPDATE: tested it and it does work.

Randomizing the whole list each time is overkill.

Generate a random integer instead, and then select taht item from the list.

If you want random without replacement, then randomize the list once, and take the items in order. When you get to the end of the list, randomize the whole list again.

Thanks fellas.

Yep...

 list message = ["turn left", "turn right", "up", "down", "all around"];
 integer messageNumber;
 
 default
 {
 	touch_start(integer touchy)
 	{
 		messageNumber = (integer)llFrand((float)llGetListLength(message));
 		llWhisper(0,llList2String(message,messageNumber)); //returns messageNumber message in list
 	}
 }
   

Now how would you get this to read from a notecard?

Was searching for days for that, don't no how i missed it, thanks

Still more efficient to just keep generating the random number and not use llRandomizeList at all, especially as the list length grows.

EDIT: I was putting the reference here but I see Ruthven beat me to the punch.

This line is interesting, I never thought to do it this way:

messageNumber = (integer)llFrand((float)llGetListLength(message));

It looks like this would never retrieve the final (total) numbered mesage item. Is that right? I've been using llFloor or llCeil to get integers afer randomizing.

llFrand picks a random number between 0 and the number given. in this case it's the length of the list. however, if it does happen to pick that length, it will return an empty string because the list indexes start at 0

so basically if you have a list of 24 messages, you would actually want to do something like this so it picks a random number between 0 and 23, because 23 will be the index for the last message

integer len = llGetListLength(messages);
integer index = (integer)llFrand(len-1);//minus the length by 1 so that it will be a random number between 0 and the last index instead of the length
llWhisper(0,llList2String(messages,index));

Yes, sorry, that was a mistake. It works, but it should be length-1.

llFrand(max) generates a number between 0.0 and max.
This means max is not included.
Casting the generated float to a integer leaves you with the greatest integer smaller than the float.

The highest integer you an get from llFrand(5.0) = 4

In other words: there's no need for the -1.

This is from the wiki:

yep, thought about that last night ron. probably why they paladin mentioned llFloor, but that floats down so it's still gonna give the same result as casting it to an integer. using llRound will round it to the nearest, up or down. so it could be:

integer index = llRound(llFrand(len-1));
