Question

我目前正在处理一个闪存程序，它会在设定的时间内定期增加和减少一个变量。要做到这一点，我使用TweenLite。我现在的问题是：

我希望这个数字总是6个数字。因此，数字10将显示为000010. 156将为000156，依此类推。我的程序当前只显示10或156.

如何制作，以便特定文本框始终为XXXXXX格式？

我的情况与大多数情况略有不同的原因是因为我的数字增加很多，这意味着它们从X变为XX流动，所以简单地在我的数字之前坚持0000不是对这个问题的有效回应当数字从X变为XX等时，技术上会有一个额外的0投入混合

我目前在我的flash程序中有以下代码：

import com.greensock.*;
import com.greensock.easing.*;

var score:Number = 0;             // starting value
var targetScore:Number = 0;            // the value that the starting value will change
                                       // to (it increases before *score* increases)

function showScore():void{
    score_mc.score_txt.text = int(score);         //display score in my text box
    }

button_btn.addEventListener(MouseEvent.CLICK, increaseScore);

function increaseScore(e:MouseEvent):void{
    targetScore+=10;                                 //increase targetScore before score
    TweenLite.to(this, 1, {score:targetScore, onUpdate:showScore, ease:Linear.easeNone}); 
                           // increase score to the same value as target score, 
                           // over 1 second. The Linear.ease bit simply makes it 
                           // a constant change from one number to the next.
    }

编辑：这似乎完美无缺（考虑到文本的原始格式：

import com.greensock.*;
import com.greensock.easing.*;

var score:Number = 0;
var targetScore:Number = 0;  

function showScore():void{
    score_mc.score_txt.defaultTextFormat = score_mc.score_txt.getTextFormat();
    if (score < 10){
        score_mc.score_txt.text = "00000" + int(score);
    } else if (score < 100) {
            score_mc.score_txt.text = "0000" + int(score);
        } else if (score < 1000) {
            score_mc.score_txt.text = "000" + int(score);
        } else {
            score_mc.score_txt.text = "00" + int(score);
        }

}

button_btn.addEventListener(MouseEvent.CLICK, increaseScore);
function increaseScore(e:MouseEvent):void{
    targetScore+=900;
    TweenLite.to(this, 2, {score:targetScore, onUpdate:showScore, ease:Linear.easeNone});

    }

Answer 1

这样的事情应该有效：

public function printScore( score:int ):String
{
    var str:String = "00000" + score; // add the max leading zeros to your number
    return str.substr( str.length - 6 ); // return only the last 6 chars
}

Answer 2

您可以尝试稍微修改一下代码：

function showScore(newScore:String):void{
    score_mc.score_txt.text = newScore;         //display score in my text box
}

还有tweenlite代码：

function increaseScore(e:MouseEvent):void{
   targetScore+=10;                                 //increase targetScore before score
   var newScore = targetScore.toString("000000");
   TweenLite.to(this, 1, {score:targetScore, onUpdate:showScore, onUpdateParams:[newScore], ease:Linear.easeNone}); 
}

Answer 3

这似乎可以完成这项工作，但其他人已经留下了可能更实用且更适合计算机的答案，

import com.greensock.*;
import com.greensock.easing.*;

var score:Number = 0;
var targetScore:Number = 0;

function showScore():void{
    if (score < 10){
        score_mc.score_txt.text = "000" + int(score);
    } else if (score < 100) {
            score_mc.score_txt.text = "00" + int(score);
        } else if (score < 1000) {
            score_mc.score_txt.text = "0" + int(score);
        }

}

button_btn.addEventListener(MouseEvent.CLICK, increaseScore);
function increaseScore(e:MouseEvent):void{
    targetScore+=50;
    TweenLite.to(this, 2, {score:targetScore, onUpdate:showScore, ease:Linear.easeNone});

    }
