Make your own generators!

Do you use generators? Want to create your own? This basic javascript tutorial will show you how to first, create them, then make them cool! Here we are going to make a sword gen. It will be two words, the quality and either short,long, or broad sword.

First let's create the gen.

We are going to make an array.


var qua=new Array()

qua[0]="very poor"

//Notice that the number above starts with 0 not 1.

//It's a common mistake to start with one which will result in 

//"undifined" showing up sometimes


qua[1]="poor"

qua[2]="average"

qua[3]="slightly above average"

qua[4]="good"

qua[5]="Great"

qua[6]="Masterwork"

Now we have the quality set. Now we need to make the sword


var sword=new Array()

sword[0]="short sword"

sword[1]="long sword"

sword[2]="broad sword"

Remember to start with 0!
Both those go in the head tag of your document. Feel free to add more to this generator such as length,weight,element(if any),etc...
To make this work, in the body of your document add this


<script type="text/javascript">

document.write(qua[Math.floor(Math.random()*6)])

document.write( )

// ↑ to add a space between the quality and the sword name

document.write(sword[Math.floor(Math.random()*2)])

This will write the results when the page loads.

Why Math.floor, why not Math.round?
Math.floor always rounds down, and Math.round will round either way. Without the .floor we would get a decimal like 4.5684527564 instead we want an integer, so we use Math.floor.
Make sure you capitalize the M in math.
It may be possible to generate images. If you know the answer to this, please post in the message boards.

If you want to make it look cool you could create an image as a background for a page. The image could be anything you want, it could be an ipod,a cow,a doughnut,even a swimming pool! Then just on part of the image add the code to make your results appear.

This could also be used for a random sign generator.

I won't update it anymore, but it will work as examples.
I hope you enjoyed the tutorial, please comment!
