I want to get ten random numbers between 1-20

PHP Code:

random_num(1,20) 


but I want to get 10 numbers and the numbers will not return them self
that i'll get ten numbers in random order

Maybe something like this...

PHP Code:

public Myfunc( ) {
    new iNumbers[ 10 ];
    
    GetRandomNumbers( iNumbers );
}

stock GetRandomNumbers( iOutput[ 10 ] ) {
    new j, iRandom, iDone, bool:bNext, Array:aNums = ArrayCreate( );
    
    for( new i; i < 10; i++ ) {
        bNext = false;
        
        iRandom = random_num( 1, 20 );
        
        for( j = 0; j < iDone; j++ ) {
            if( ArrayGetCell( aNums, i ) == iRandom ) {
                bNext = true;
                
                break;
            }
        }
        
        if( bNext )
            continue;
        
        ArrayPushCell( aNums, iRandom );
        
        iOutput[ iDone ] = iRandom;
        
        iDone++;
    }
    
    ArrayDestroy( aNums );
} 


EDIT: Uhm... this wont work properly, i am lazy to fix it now, maybe someone can

[zacky]

I don't know if this will work
But can't you do this?

PHP Code:

new iNumbers[10];

for (new i; i < 10; i++) {
    iNumbers[i] = random_num(1, 20);
}

He dont want the numbers to be twice or more

Where did you get that from?
He said he wanted 10 random numbers.

From that. It's understandable even not clear.

You guys are taking the wrong approach.

new iNumbers[ 10 ];
GetRandomNumbers( 1, 20, iNumbers, 10 );

GetRandomNumbers( const iStart, const iStop, iResults[ ], const iSize )
{
    if( iStart >= iStop )
    {
        return 0;
    }
    
    new Array:aNumbers = ArrayCreate( 1 );
    new iArraySize = iStop - iStart + 1;
    
    for( new i = 0; i < iArraySize; i++ )
    {
       ArrayPushCell( aNumbers, i + iStart );
    }
    
    new iLastIndex = min( iArraySize, iSize );
    new iRand;
    for( new i = 0; i < iLastIndex; i++ )
    {
        iRand = random( iArraySize );
        
        iResults[ i ] = ArrayGetCell( aNumbers, iRand );
        ArrayDeleteItem( aNumbers, iRand );
        
        iArraySize--;
    }
    
    ArrayDestroy( aNumbers );
    
    return iLastIndex;
}

new iNumbers[10]
for (new i=0; i < 10; i++)
{
iNumbers[i] = random_num(1, 20)
for (new j=0; 1 < i; j++)
{
if (iNumbers[i] == iNumbers[j] && i != j)
i = i-1
}
}

Correct me if i'm wrong..

Yes you are wrong.
Your code does unnecessary checks and could execute more loops than needed.
See my code.

But my code repeat the loop if the random name was obtain before, else the loop runs normally
