如何将数组的项目与as3中的第二个数组的项目相关联

Question

我正在尝试在 as3 中构建一个 wordsearch，但我发现很难弄清楚如何将 wordsearch 中找到的单词（称为解决方案的数组）与旁边的单词（称为 lexeis 的数组）关联起来，这样每次一个单词（解决方案)在边上找到要删除的单词（从数组lexeis中）。 我有这个代码

 var wordSearch:Array = [
 ["Π", "Σ", "Ξ", "Χ", "Υ", "Π", "Ο"],
 ["Χ", "Σ", "Υ", "Χ", "Υ", "Π", "Ο"],
 ["Α", "Φ", "Σ", "Κ", "Θ", "Ρ", "Υ"],
 ];
 var solutions:Array = [
     [[0, 1], [0, 6]], 
     [[0, 4], [7, 4]], 
     [[1, 3], [1, 8]], 
 ]

 var lexeis:Array = ["ΧΑΡΤΗΣ", "ΚΑΣΕΤΙΝΑ"];
 myTextField_txt.text = [lexeis].toString();
 myTextField_txt.multiline=true;
 myTextField_txt.wordWrap=true;
 myTextField_txt.autoSize=TextFieldAutoSize.LEFT;
 myTextField_txt.text =lexeis.join("\n");

 // build word search buttons
 var i:int = 0, j:int = 0, posX:int = 0, posY:int = 0, buttonSize:int = 35;
 var buttonTextFormat:TextFormat = new TextFormat("Arial,Verdana",16,0x333333,true);
 while(i < wordSearch.length){
     posX = 0;
     j = 0;
     posY = i * buttonSize;

while(j < wordSearch[0].length) {
    posX = j * buttonSize;

    if (wordSearch[i][j] == "%")
        wordSearch[i][j] = String.fromCharCode(97 + int(26 * Math.random())); // random a-z lowercase

    var b:Button = new Button();
    b.setSize(buttonSize, buttonSize);
    b.move(posX +30, posY+115);
    b.label = wordSearch[i][j];
    b.name = "btn" + j + "_" + i;
    b.setStyle("textFormat",buttonTextFormat);
    addChild(b);

    j++;
}
i++;
}

 // this graphic will be used to draw graphics around the solved words
 var solvedWords:Shape = new Shape();
 addChild(solvedWords);

 // start and end points when searching for a solution
 var startLetter:Array, endLetter:Array;
 var startButton:Button, endButton:Button;

 // event listeners for click and drag
 addEventListener("mouseDown",mouseDown);

 function mouseDown(event:MouseEvent){
     stage.addEventListener("mouseMove",mouseMove);
     stage.addEventListener("mouseUp",mouseUp);
     startLetter = getLetterFromName(event.target.name);
     startButton = event.target as Button;
     endButton = startButton;
     updateDrag();
 }

function mouseMove(event:MouseEvent){
    updateDrag();
 }

 function mouseUp(event:MouseEvent){
     checkForSolution();
     stage.removeEventListener("mouseMove",mouseMove);
     stage.removeEventListener("mouseUp",mouseUp);
 }

 // update the dragging interaction
 function updateDrag(){
// find the button currently under the mouse
var objects:Array = getObjectsUnderPoint(new Point(mouseX,mouseY));
while(objects.length && !(objects[0].parent.parent is Button))
    objects.shift();
if(objects.length)
    var btn:Button = objects[0].parent.parent as Button;

// if there's a button under the mouse, check to see if it's on a good axis (vertical, horizontal, diaganal
if(btn){
    var letter:Array = getLetterFromName(btn.name);
    if(letter[0] == startLetter[0] || letter[1] == startLetter[1]
    || Math.abs(letter[0] - startLetter[0]) == Math.abs(letter[1] - startLetter[1])){
        endLetter = letter;
        endButton = btn;
    }
}

// draw a visual line between the start button and the end button
graphics.clear();
graphics.lineStyle(LINE_WIDTH,0x0077ff);
graphics.moveTo(startButton.x + startButton.width/2,startButton.y + startButton.height/2);
graphics.lineTo(endButton.x + endButton.width/2,endButton.y + endButton.height/2);
 }


 // check to see if the current dragging operation has found a solution
 var fadeTween:Tween;
 function checkForSolution(){
// clear temporary visual indicator of user select start/end letter
graphics.clear();

// check each solution to see if it matches what user selected
for(var i in solutions){
    if((compareLetters(solutions[i][0], startLetter) && compareLetters(solutions[i][1], endLetter))
    || (compareLetters(solutions[i][0], endLetter) && compareLetters(solutions[i][1], startLetter))) 
{
        // solution found! 

        // draw perminant graphic around them
        with(solvedWords){
            graphics.lineStyle(LINE_WIDTH,0x0077ff,.25);
            graphics.moveTo(startButton.x + startButton.width/2,startButton.y + startButton.height/2);
            graphics.lineTo(endButton.x + endButton.width/2,endButton.y + endButton.height/2);

        }

        // remove the solution so that there are no repeats
        solutions.splice(i,1);

        break;

       } 
     }

     // if all solutions have been found, show a "YOU WIN!" graphic
     if(!solutions.length){
    var w:int = 400, h:int = 100;

    // show center "YOU WIN!" text

    tf.selectable = false;
    win.addChild(tf);
    tf.x = w/2 - tf.width/2;
    tf.y = h/2 - tf.height/2;

    // add a drop shadow
    var dropShadow:DropShadowFilter = new DropShadowFilter(3,45,0,.35,8,8,1,3);
    win.filters = [dropShadow];

    // center the graphic
    win.x = stage.stageWidth/2 - win.width/2;

 // gets a letter array like [x,y] from a Button name like "btnX_Y"
