GetRandomInt can only get one number, I want to get multiple non-repeating numbers, and I need to limit the number of random numbers obtained from not coexisting
Example:
Random number = {A,B,C,D,E,0,1,2,3,4}, get 3 of them and cannot repeat
When A and 0 cannot coexist
Random Number = A, B, C (Correct)
Random number = A,0,4 (false)

PHP Code:

int MyArray[10]={A,B,C,D,E,0,1,2,3,4};
int Chosen[3];

My_Function()
{
    int X,i,j;
    while (i < 3)
    {
        X = MyArray[ GetRandomInt(0,9) ];
        
        j=0;
        while (j < i)        //Loop2 Through Values To Check
        {
            if ( X==Chosen[j] || ( (X==A || X==0) && (Chosen[j]==A || Chosen[j]==0) ) )
            {    
                j = -1;
                break;        //Try Another Random
            }
            j++;
        }
        
        if (j != -1)    Chosen[i++]=X;
    }
    //test :
    for (int k=0 ; k <3 ;k++)    PrintToServer("Value #%d : %d .",k+1 , Chosen[k]);
}

PHP Code:

static const int MY_ARRAY[] = {0xA, 0xB, 0xC, 0xD, 0xE, 0, 1, 2, 3, 4};

void GetRandom()

    ArrayList hList = CreateArray();
    int i = -1, rnd[3], pos;
    for(; ++i < sizeof(MY_ARRAY);) hList.Push(MY_ARRAY[i]);

    for(i=-1; ++i < 3 && hList.Length;)
    {
        rnd[i] = hList.Get(GetRandomInt(0, (hList.Length - 1)));
        hList.Erase(i);
        if((rnd[i] == 0xA && (pos = hList.FindValue(0)) != -1) || (rnd[i] == 0 && (pos = hList.FindValue(0xA)) != -1))
            hList.Erase(pos);
    }
    CloseHandle(hList);

    PrintToChatAll("Random number = %i, %i, %i", rnd[0], rnd[1], rnd[2]);

brilliant! , But you must delete hList in order to prevent any extra memory usage .
Handles will not be deleted until the plugin unloaded .So you have to delete them manually when you have finished , Or You may public that arraylist handle to be the only one that handle data then use Clear after usage .
