#1009 空对象引用（AS3、TextField）
我需要一些帮助（我是这个网站的新手）
我想要打字机效果。这样看起来字符串中的代码是逐字符键入的（对于动画）。然而，我得到了#1009 回复。它谈论空对象引用（错误是荷兰语）。
我的动态文本字段位于同一场景中的不同图层上。 codeTekst 是实例名称。这是经典的、充满活力的文本。多行行为并且未嵌入符号中。我正在使用 Flash CS5。这是我的代码：
import flash.utils.Timer;
import flash.events.TimerEvent;
var string:String = 'import flash.events.Event import flash.utils.Timer; import flash.events.TimerEvent; import flash.display.MovieClip; import flash.events.MouseEvent; import flash.media.Sound; import flash.media.SoundChannel; stop(); var beginSchermSpraak:Sound = new BeginSchermSpraak(); var beginSchermSpraakKanaal:SoundChannel = new SoundChannel(); var helpKnopSpraak:Sound = new HelpKnopSpraak(); var helpKnopSpraakKanaal:SoundChannel = new SoundChannel(); var eersteKeer:Boolean; var gebouw:uint; var vandaan:Boolean; var timer:Timer = new Timer(1, 1); splashMC.x=-9001; startKnop.x=-9001; if (eersteKeer == false) { splashMC.x=250; startKnop.x=250; beginSchermSpraakKanaal = beginSchermSpraak.play(); beginSchermSpraakKanaal.addEventListener(Event.SOUND_COMPLETE, helpKnopMaken); startKnop.addEventListener(MouseEvent.CLICK, startTimer); timer.addEventListener(TimerEvent.TIMER_COMPLETE, vervaag); } else {}';
var i:uint = 0;
var timer:Timer = new Timer(10);
timer.start();
timer.addEventListener(TimerEvent.TIMER, goTime);
function goTime(e:TimerEvent){
codeTekst.appendText(string.charAt(i));
i++;
if(i>=string.length) {
timer.stop();
}
}
感谢您的任何想法:)
I would like some help (and I'm new to this site)
I want a typewriter-effect. So that it looks like the code in the string is typed character by character (for an animation). However, I get a #1009 back. It talks about a null object reference (the error is in Dutch).
My dynamic text field is in the same scene, on a different layer. codeTekst is the instance name. It is classic, dynamic text. Multiline behaviour and not embedded in a symbol. I'm using Flash CS5. Here is my code:
import flash.utils.Timer;
import flash.events.TimerEvent;
var string:String = 'import flash.events.Event import flash.utils.Timer; import flash.events.TimerEvent; import flash.display.MovieClip; import flash.events.MouseEvent; import flash.media.Sound; import flash.media.SoundChannel; stop(); var beginSchermSpraak:Sound = new BeginSchermSpraak(); var beginSchermSpraakKanaal:SoundChannel = new SoundChannel(); var helpKnopSpraak:Sound = new HelpKnopSpraak(); var helpKnopSpraakKanaal:SoundChannel = new SoundChannel(); var eersteKeer:Boolean; var gebouw:uint; var vandaan:Boolean; var timer:Timer = new Timer(1, 1); splashMC.x=-9001; startKnop.x=-9001; if (eersteKeer == false) { splashMC.x=250; startKnop.x=250; beginSchermSpraakKanaal = beginSchermSpraak.play(); beginSchermSpraakKanaal.addEventListener(Event.SOUND_COMPLETE, helpKnopMaken); startKnop.addEventListener(MouseEvent.CLICK, startTimer); timer.addEventListener(TimerEvent.TIMER_COMPLETE, vervaag); } else {}';
var i:uint = 0;
var timer:Timer = new Timer(10);
timer.start();
timer.addEventListener(TimerEvent.TIMER, goTime);
function goTime(e:TimerEvent){
codeTekst.appendText(string.charAt(i));
i++;
if(i>=string.length) {
timer.stop();
}
}
Thanks for any ideas :)

您是否检查过以确保文本字段在开始时不为空白？ Flash 中有一个错误，因此您必须在框中包含一些文本，否则您将收到 null 错误。
还要确保嵌入字体。
Did you check to make sure the text field was not blank to start? There is a bug in flash, so you have to have some text in the box, or you will get the null error.
Also make sure you embed the font.
该代码对我来说运行良好；复制并粘贴到 Flash CS5 中。我所做的唯一一件事是添加一个 TextField 并为其指定一个实例名称“codeTekst”。您确定您的 TextField 实例在您的代码所在的框架上可用吗？
The code runs fine for me; Copied and pasted into Flash CS5. Only other thing I did was add a TextField and gave it an instance name of "codeTekst". Are you sure that your TextField instance is available on the frame that your code is on?
