generate random number

just use Math.round(GetUniform()); for 0 and 1

noooooooooooooooooooooooooooooooooooooooooooooooooooo

Calls to Math are expensive since this will be every frame use bitwise tricks

nice algorithm though

Here you go man

I remember we learned this stuff on Algorithms and Data structures subject I had 2 years ago, so I found algorithm in C++ and modified it. It’s your lucky day

var date:Date = new Date(); //we use date to get different seeds

//seeds
var m_w:uint = date.getSeconds()+1;     //must not be 0, so we add 1, that should work...
var m_z:uint = date.getMilliseconds()+1;  //same here..
//Marsaglia's MWC algorithm 
function GetUint():uint
{
    m_z = 36969 * (m_z & 65535) + (m_z >> 16);
    m_w = 18000 * (m_w & 65535) + (m_w >> 16);
    return (m_z << 16) + m_w;  
}
function GetUniform():Number
{
    var u:uint = GetUint();
    return (u + 1) * 2.328306435454494e-10;
}

//100 random numbers between 0 and 1 
for(var i=0; i<100; i++){
trace(GetUniform());
}

p.s.

don’t try to understand how it works, just use it

edit:

just use Math.round(GetUniform()); for 0 and 1

Thanx alot ivan!

But i cant seem to get it to work for as2. Keep on sying that it can’t load the right class?!

Any ideas

hehehe, you’re right, that would be much better solution

Thanx alot ivan!

why you use as2? There is no unsigned integer data type in as 2…that’s the problem

Yeah, i’v taken that out… but still no difference! but i probably need uint to get it to work?!

The reason why i use AS2 is becouse i’ve made the script a long time ago. But now i just need to update it so i can use the banner for Google adwords

But i cant seem to get it to work for as2. Keep on sying that it can’t load the right class?!

what class is that, whats the error exactly? Maybe its a hint to use AS3

Yeah, i know its AS3 . But i don’t have that much knowledge of AS3 to rebuild my whole application

I’m still oldscool

As I said, this is your lucky day

var date:Date = new Date(); //we use date to get different seeds

//seeds
var m_w:Number =  date.getSeconds()+1;     
var m_z:Number = date.getMilliseconds()+1;  

//Marsaglia's MWC algorithm 
function GetUint():Number
{
    m_z = 36969 * (m_z & 65535) + (m_z >> 16);
    m_w = 18000 * (m_w & 65535) + (m_w >> 16);
    return (m_z << 16) + m_w;  
}
function GetUniform():Number
{
    var u:Number = GetUint();
    return (castToUint(u) + 1) * 2.328306435454494e-10;
}

//100 random numbers
for(var i=0; i<100; i++){
trace(GetUniform()+0.5|0);
}

function castToUint(x:Number):Number{
    return x < 0 ? x+4294967295 : x;
}

problem is there is no uint data type in as2, so it reports error that class or interface ‘uint’ could not be loaded. But I came to idea to “make” uint with this

so if its less than 0 add maximum value of uint so you get positive representation of that value. That should do the job.

Thanx Ivan,

Guess it is my lucky day Now i’m getting a returned value! The only thing is…. the only return value that i get is 0.

Any ideas why that’s the case?

well I guess your doing something wrong, because this works fine for me.
