Hey!
After a thread I helped someone in to do with dice, I was inspired to make a tutorial on creating a flash fruit machine.
So here we go…
[size=5][color=red]Random Numbers[/color][/size]
[color=black]The first thing you need to know about is random numbers.[/color]
The first function you need to know about is Math.random(). It creates a random number from 0 to 1. Now I know that you’re thinking that an endless stream of decimals is not much use… So what about Math.random() * 10? That creates a number from 0-10! But it still has a random stream of decimals 
. So we need to round it to the nearest whole number! So it’s Math.round() to the rescue! Math.round rounds to the nearest whole number. So now we have Math.round(Math.random * 10)… What if we want a number from 1-10? We use Math.ceil, it always rounds up, so 0 is impossible! The opposite of Math.ceil is Math.floor, so you will get a random number from 0-9.
Anyhoo, here is a summary of this part:
[list]
[]Use Math.random() for a random number from 0-1
[]Multiply it by 10 for a random number from 0-10
[*]Use Math.round(), Math.ceil and Math.floor to round numbers.
[/list]That’s it for part one. Mess around with it, because next lesson we will make the screens with a random number!
Enjoy!
