Hello, all.

I would like to have a script that gives me a random number from an input number.
I.e. if I typed "/random 6" in the text box and sent it, it would give me a random number between 0 and 6.
And I don't want 6 to be the only number that can be randomized, I want the number after /random # to be a user input.

Any help?

xxxx says: 4
xxxx says: 8
xxxx says: 12
xxxx says: 0
xxxx says: 6
xxxx says: 5

/random 12

There are already many scripts which can do that, have a look in the scripts database.

The only problem I see is that you want a random number in the range of 0..n, whereas most dice roller scripts work in the range of 1..n (with n the upper limit). You could get around this by using a more advanced dice rolling formula, for example to roll between 0 and 12 you could use this command for Advanced Dice Roller:

code:

---

/roll 1d13-1

---

quote:

---

Alias: /random12
Text: /dice 1d13-1

Wow thanks a bunch!

I already searched the script database, but I literally used the search function and I guess I was looking up the wrong keywords (number,random).

js code:

---

function OnEvent_ChatWndSendMessage(oChatWnd, sMessage){
    if (/^\/([^\s\/]+)\s*([\s\S]*)$/.exec(sMessage) !== null) {
        var Command = RegExp.$1.toLowerCase();
        var Param = parseFloat(RegExp.$2);
        switch (Command) {
            case 'random':
                if (Param !== 'NaN') {
                    return Math.floor((Param)*Math.random());;
                } else {
                    return '';
                }
        }
    }   
    return sMessage;
}

Ah, matty goes the DIY way again!

However, I think you have a small error in your error handling. When parseFloat can't convert Param into a valid floating point number, it'll return NaN. Now, NaN isn't just a string containing those three letters, it's a special value and - ironically - is of the type Number.

The correct way to see whether the result is valid is by using the isNaN function provided by JScript/JavaScript. I also recommend doing the parseFloat call after confirming that the /random command was sent. So, this would be the corrected code:

js code:

---

function OnEvent_ChatWndSendMessage(oChatWnd, sMessage){
    if (/^\/([^\s\/]+)\s*([\s\S]*)$/.exec(sMessage) !== null) {
        var Command = RegExp.$1.toLowerCase();
        var Param = RegExp.$2;
        switch (Command) {
            case 'random':
>>>                if (!isNaN(Param = parseFloat(Param))) {<<<
                    return Math.floor((Param)*Math.random());;
                } else {
                    return '';
                }
        }
    }   
    return sMessage;
}

Yes, that line is perfectly valid. First I re-assign Param to the parseFloat result, then that result is checked against isNaN. Neat, uh?

Wow shows how rusty I am... good catch my young padwan.
