Question

在我创建的这个程序中，有四种不同颜色的块（红色，绿色，蓝色和黄色。计算机隐藏了三个不同颜色的块。用户然后尝试猜测颜色和顺序猜测三个隐藏块的颜色后，计算机会显示有多少颜色是正确的，有多少颜色位于正确的位置。我遇到的麻烦就是函数checkColoursCorrect（）和checkPositionsCorrect（我总是在结果中得到0或者1。我从来没有得到2或3个位置/颜色正确。请告诉我我做错了什么。这是我的代码：

btnCheckGuess.addEventListener(MouseEvent.CLICK, checkGuess);

btnNewGame.addEventListener(MouseEvent.CLICK, newGame);

// Declare Global Variables

var computerBlock1:String;  // the computer's first block

var computerBlock2:String;  // the computer's second block

var computerBlock3:String;  // the computer's third block


function checkGuess(e:MouseEvent):void
{  
var userGuess1:String;   
var userGuess2:String  
var userGuess3:String;    
var coloursCorrect:int;     
var positionsCorrect:int;   


userGuess1 = txtinBlock1.text;
userGuess2 = txtinBlock2.text;
userGuess3 = txtinBlock3.text;
userGuess1 = userGuess1.toUpperCase();
userGuess2 = userGuess2.toUpperCase();
userGuess3 = userGuess3.toUpperCase();

coloursCorrect = checkColoursCorrect(userGuess1,userGuess2,userGuess3);
positionsCorrect = checkPositionsCorrect(userGuess1,userGuess2,userGuess3);
lblOutput.text = "Number of Colours Correct = " + coloursCorrect.toString() + "\r";
lblOutput.text += "Number of Positions Correct = " + positionsCorrect.toString();
}


// g1– the user's guess of the first block
// g2– the user's guess of the second block
// g3– the user's guess of the third block

function checkColoursCorrect(g1:String,g2:String,g3:String):int
{

if(g1 == computerBlock1){
    return 1
}

if(g2 == computerBlock2){
    return 1
}

if(g3 == computerBlock3){
    return 1
}
return 0;
}


// g1– the user's guess of the first block
// g2– the user's guess of the second block
// g3- the user's guess of the third block
function checkPositionsCorrect(g1:String,g2:String,g3:String):int
{

if(g1 == computerBlock1){
    return 1
}
if(g2 == computerBlock2){
    return 1
}
if(g3 == computerBlock3){
    return 1
}
return 0;   
}

function newGame(e:MouseEvent):void
{
var block1:int;     
var block2:int;     // numbers representing hidden block
var block3:int;     

// generate three unique numbers between 1 and 4 for the block numbers
block1 = randomWholeNumber(4,1);
block2 = randomWholeNumber(4,1);
block3 = randomWholeNumber(4,1);

// convert block numbers to letters 1-R, 2-G, 3-B, 4-Y
if (block1 == 1) {
    computerBlock1 = "R";
} else if (block1 == 2) {
    computerBlock1 = "G";
} else if (block1 == 3) {
    computerBlock1 = "B";
} else if (block1 == 4) {
    computerBlock1 = "Y";
}

if (block2 == 1) {
    computerBlock2 = "R";
} else if (block2 == 2) {
    computerBlock2 = "G";
} else if (block2 == 3) {
    computerBlock2 = "B";
} else if (block2 == 4) {
    computerBlock2 = "Y";
}

if (block3 == 1) {
    computerBlock3 = "R";
} else if (block3 == 2) {
    computerBlock3 = "G";
} else if (block3 == 3) {
    computerBlock3 = "B";
} else if (block3 == 4) {
    computerBlock3 = "Y";
}

txtinBlock1.text = "";
txtinBlock2.text = "";
txtinBlock3.text = "";
lblOutput.text = "";
}

function randomWholeNumber(highNumber:int,lowNumber:int):int

{

return Math.floor((highNumber - lowNumber + 1) * Math.random() + lowNumber);

}

Answer 1

我认为你对return的作用有误解。你的两个方法都只会返回0或1。

我相信你真正想要做的是每次用户猜对话时增加一个值，然后返回该值：

function checkColoursCorrect(g1:String,g2:String,g3:String):int
{
    var coloursCorrect:int = 0; 
    if(g1 == computerBlock1){
        coloursCorrect++;
    }

    if(g2 == computerBlock2){
        coloursCorrect++;
    }

    if(g3 == computerBlock3){
        coloursCorrect++;
    }
    return coloursCorrect;
}
