Как сделать рандомное появление 6 юнитов в 12 возможных областях

Если перевести выше сказанное

//! zinc
library Spawn {
    rect RCT[];

    function onInit(){
        integer i, j, k, t, arr[];
        real x, y;
        rect rct;
        
        RCT[0] = gg_rct_Spawn00;
        RCT[1] = gg_rct_Spawn01;
        RCT[2] = gg_rct_Spawn02;

        k = 10;
        for(0 <= i < k){
            arr[i] = i;
        }
        
        for(0 <= i < k) {
            j = GetRandomInt(0, k-1);

            arr[j] = t;
        }
        
        for(0 <= i < 6){
            rct = RCT[arr[i]];
            x = GetRectCenterX(rct);
            y = GetRectCenterY(rct);
            CreateUnit(Player(0), 'hfoo', x, y, GetRandomReal(0, 360));
        }
