generate random number

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.

Guess your right . when i put it in another flie, it works perfect

function AnimateGrid():Void {

    for(var v=0; v < arrGrid[0][1]; v++) { // vertical pixels
        vpos = v * psize;
        for(var h=0; h<arrGrid[0][0]; h++) {

            index++;    
            hpos = h * psize;

            var pv = bmp.getPixel(hpos,vpos);        
            var ps = symbols.attachMovie("mcSymbols_holder","s"+index,index,{_x:hpos,_y:vpos,_alpha:0});
            mc_text.alphaTo(100, 1, "easeOutCubic");
            var cw = ColorAmount("0x"+pv.toString(16));

            if(cw >= 0 && cw <= 20) {
                ps.pos = 6;
                ps.cover = 10;
            } else if(cw > 20 && cw <= 35) {
                ps.pos = 5;
                ps.cover = 50;
            } else if(cw > 35 && cw <= 50) {
                ps.pos = 4;
                ps.cover = 50;
            } else if(cw > 50 && cw <= 65) {
                ps.pos = 3;
                ps.cover = 50;
            } else if(cw > 65 && cw <= 80) {
                ps.pos = 2;
                ps.cover = 30;
            } else {
                ps.pos = 1;
                ps.cover = 10;
            }

            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;
            }

                        // this is the Math.random() i have to change

            ps.symbols.gotoAndPlay(Math.round(Math.random() * 5 + 1));
            ps._alpha = Math.round(Math.random() * 100); // ps.cover;
            var delay : Number = Math.round(Math.random() * 2000 + 1000)
            setTimeout(ShowTile, delay, index, delay);
            trace(Math.round(Math.random() * 5 + 1));
        }
    }
}

well you cant put all this inside one function just like that

You have to watch on scope. Paste all this code beside other functions not inside. And then just use GetUniform()+0.5|0; to get random number inside your function or wherever you need it.

I must go now, hope I helped you

cya

Ivan

Ivan,

Thank you very much!!!

I’ve got it to work!!!

replaced GetUniform()+0.5|0 for Math.round(GetUniform()); and delete the for loop!!!

Guess it was my lucky day after all
