Question

AS3.0 TypeError: Error #1009: 无法访问空对象引用的属性或方法

stop();
pointTx.text=point

add1p2.addEventListener(MouseEvent.CLICK,adding1p2);
add1p2O.addEventListener(MouseEvent.CLICK,adding1p2);
add2p2.addEventListener(MouseEvent.CLICK,adding2p2);
backBt.addEventListener(MouseEvent.CLICK,back);

function adding1p2(event:MouseEvent):void{
point+=1;
pointTx.text=point;
trace(point+"/"+points+"-"+player)
if(point==points-1){
add1p1O.x=250
add1p1O.y=350
}
if(point>=points){
gotoAndPlay(6);
}else{
player=2;
gotoAndPlay(3);
}
}
function adding2p2(event:MouseEvent):void{
point+=2
pointTx.text=point
trace(point+"/"+points+"-"+player)
if(point==points-1){
add1p1O.x=250
add1p1O.y=350
}
if(point>=points){
gotoAndPlay(6);
}else{
player=2;
gotoAndPlay(3);
}
}

测试时出现以下问题：
TypeError: Error #1009: 无法访问空对象引用的属性或方法。
at _fla::MainTimeline/frame4()
at flash.display::MovieClip/gotoAndPlay()
at _fla::MainTimeline/adding1p1()
请问如何修改

Answer 1

看你的代码和报错信息 应该是代码写在一些分散的帧上，报错的是adding1p1 但是你给的代码里没有

检查下时间轴第4帧 你adding1p1函数会用到的东西还在不在舞台上

Answer 2

你代码中的point points这些变量声明了吗？
