如何将每一部电影排成一行
如何将每一部电影排成一行
提问于 2014-03-24 20:30:19
我会接受你的帮助。我有8个电影(正方形1-8)和一个叫plus1的电影在舞台上处理8电影。我想点击plus1一次和颜色square1，第二次按plus1和颜色square2等等。这是我的代码，但似乎有什么问题，因为它的颜色随机。你能帮我找出它的什么毛病吗？
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.geom.ColorTransform;
plus1.buttonMode=true;
var sximata:MovieClip = square1;
var myColorTransform:ColorTransform = new ColorTransform();
plus1.addEventListener(MouseEvent.CLICK, changeColour);
function changeColour(event:MouseEvent):void
{
if (contains(square1))
{
removeEventListener(MouseEvent.CLICK, onsquare1);
addEventListener(MouseEvent.CLICK, onsquare16);
}
if (contains(square2))
{
removeEventListener(MouseEvent.CLICK, onsquare2);
addEventListener(MouseEvent.CLICK, onsquare3);
}
if (contains(square3))
{
removeEventListener(MouseEvent.CLICK, onsquare3);
addEventListener(MouseEvent.CLICK, onsquare4);
}
if (contains(square4))
{
removeEventListener(MouseEvent.CLICK, onsquare4);
addEventListener(MouseEvent.CLICK, onsquare5);
}
if (contains(square5))
{
removeEventListener(MouseEvent.CLICK, onsquare5);
addEventListener(MouseEvent.CLICK, onsquare6);
}
if (contains(square6))
{
removeEventListener(MouseEvent.CLICK, onsquare6);
addEventListener(MouseEvent.CLICK, onsquare7);
}
if (contains(square7))
{
removeEventListener(MouseEvent.CLICK, onsquare7);
addEventListener(MouseEvent.CLICK, onsquare8);
}
myColorTransform.color = 0xBDB522;
sximata.transform.colorTransform = myColorTransform;
}
square1.addEventListener(MouseEvent.CLICK, onsquare1);
function onsquare1(e:MouseEvent):void {
sximata = square1;
}
square2.addEventListener(MouseEvent.CLICK, onsquare2);
function onsquare2(e:MouseEvent):void {
sximata = square2;
}
square3.addEventListener(MouseEvent.CLICK, onsquare3);
function onsquare3(e:MouseEvent):void {
sximata = square3;
}
square4.addEventListener(MouseEvent.CLICK, onsquare4);
function onsquare4(e:MouseEvent):void {
sximata = square4;
}
square5.addEventListener(MouseEvent.CLICK, onsquare5);
function onsquare5(e:MouseEvent):void {
sximata = square5;
}
square6.addEventListener(MouseEvent.CLICK, onsquare6);
function onsquare6(e:MouseEvent):void {
sximata = square6;
}
square7.addEventListener(MouseEvent.CLICK, onsquare7);
function onsquare7(e:MouseEvent):void {
sximata = square7;
}
square8.addEventListener(MouseEvent.CLICK, onsquare8);
function onsquare8(e:MouseEvent):void {
sximata = square8;
}好的。我的代码现在看起来像这样
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.geom.ColorTransform;
plus1.buttonMode=true;
minus1.buttonMode=true;
var nextSquare:MovieClip = square1;
var squares:Array = [square1, square2, square3, square4, square5, square6, square7, square8];
var myColorTransform:ColorTransform = new ColorTransform();
plus1.addEventListener(MouseEvent.CLICK, changeColour);
function changeColour(event:MouseEvent):void
{
myColorTransform.color = 0x519596;
nextSquare.transform.colorTransform = myColorTransform;
var index = squares.indexOf(nextSquare);
if (index < squares.length - 1) {
nextSquare = squares[index + 1];
} else {
trace('we are done');
}
}
minus1.addEventListener(MouseEvent.CLICK, reversecolour);
function reversecolour(event:MouseEvent):void
{
nextSquare.transform.colorTransform = new ColorTransform();
var index = squares.indexOf(nextSquare);
if (index < squares.length - 1) {
nextSquare = squares[index - 1];
} else {
trace('we are done');
}
}但我知道这个错误
TypeError:错误#1009:无法访问空对象引用的属性或方法。at _fla::MainTimeline/changeColour()

不知道为什么需要这么多事件处理程序。你就不能把正方形放在一个数组里，每次点击plus1，颜色就移到下一个了吗？看看下面的代码。
plus1.buttonMode=true;
var nextSquare:MovieClip = square1;
var squares:Array = [square1, square2, square3, square4, square5, square6, square7, square8];
var myColorTransform:ColorTransform = new ColorTransform();
plus1.addEventListener(MouseEvent.CLICK, changeColour);
function changeColour(event:MouseEvent):void
{
myColorTransform.color = 0xBDB522;
nextSquare.transform.colorTransform = myColorTransform;
var index = squares.indexOf(nextSquare);
if (index < squares.length - 1) {
nextSquare = squares[index + 1];
} else {
trace('we are done');
}
