Begrænse område i actionScript

Det kan vi nok ikke gætte os til ud fra de 4 linjer dér... ;)

så får i da bare lidt mere at lege med :)
Jeg tror bare at det skal skrives til det lille stykke med kode.



function initGame () {
    // set the horizontal and vertical distance
    // between tiles
    tileDist = 77;

    // set all tiles in exactly the correct spot
    for (x=1;x<=3;x++) {
        for (y=0;y<=2;y++) {
            tile = x+y*3;
            _root["tile"+tile]._x = x*tileDist;
            _root["tile"+tile]._y = y*tileDist+tileDist;
        }
    }

    // make 10 random but valid moves
    for(tilenum=0;tilenum<10;tilenum++) {
        do {
            // pick a random tile
            tile = "tile"+(random(8)+1);
            // see whether there is an empty space near it
            emptySpace = findEmpty(tile);
        // keep looping until a tile is found that
        // has an empty space near it
        } while ( emptySpace == "none" );

        // move this tile to the empty space
        moveTile(tile,findEmpty(tile));           
    }
}

    // get location of tile
    tilex = _root[tile]._x;
    tiley = _root[tile]._y;

    // see whether there is a tile to the left
    if (tilex > tileDist) {
        if (!tileThere(tilex-tileDist, tiley)) {
            return("left");
        }
    }

Har fundet ud af det. Ellers tak
