The principle is the same as what you do with the status text.

You create an array of different texts. Then you need to get a random number which would be the number of the element to take from that array.

Random numbers can be generated like this:

code:

---

var myRandomNumber = Math.floor((upperbound - lowerbound + 1) * Math.random() + lowerbound);

---

where upperbound is the biggest number and lowerbound the lowest number in the range you which to choose from.

Thus if you whish to choose a random number from 5 to 10, you do:

code:

---

var myRandomNumber = Math.floor((10 - 5 + 1) * Math.random() + 5);

---

which equals:

code:

---

var myRandomNumber = Math.floor(6 * Math.random() + 5);

---

For the array of random texts, it is important to know that arrays start with index 0 (thus this would be our lowerbound). The length of the array determines our upperbound:

code:

---

var myTextArray = new Array("Hello", "Bonjour", "Yo", "Hi");

var lowerbound = 0;
var upperbound = myTextArray.length-1;

var myRandomNumber = Math.floor((upperbound - lowerbound + 1) * Math.random() + lowerbound);

var myRandomText = myTextArray[myRandomNumber];

---

optimized, this would be:

code:

---

var myTextArray = new Array("Hello", "Bonjour", "Yo", "Hi");
var myRandomText = myTextArray[Math.floor(myTextArray.length * Math.random())];
