我试图使用这样的矢量：

package {

    import flash.display.MovieClip;
    import flash.display.Sprite;
    import flash.utils.Timer;
    import flash.events.*;
    import classes.calculations.GeoMath;
    import classes.graphics.*;
    import classes.ui.*;

    public class Document extends MovieClip {

    var colorThemes:Vector.<Vector.<uint>> = new Vector.<Vector.<uint>>(3);

    colorThemes[0] = new Vector.<uint>(5); // 1120: Access of undefined property colorThemes.
    colorThemes[1] = new Vector.<uint>(5); // 1120: Access of undefined property colorThemes.
    colorThemes[2] = new Vector.<uint>(5); // 1120: Access of undefined property colorThemes.

    colorThemes[0][0] = 0xb26002; // 1120: Access of undefined property colorThemes.
    colorThemes[0][1] = 0xff9720; // 1120: Access of undefined property colorThemes.
    colorThemes[0][2] = 0xff8b07; // 1120: Access of undefined property colorThemes.
    colorThemes[0][3] = 0x007eb2; // 1120: Access of undefined property colorThemes.
    colorThemes[0][4] = 0x07b6ff; // 1120: Access of undefined property colorThemes.
    colorThemes[1][0] = 0xdc45ff; // 1120: Access of undefined property colorThemes.
...

如果我可以使用Vector文字来做这件事会很棒，但我也不会错误地尝试我的问题。

然后，我尝试从同一个Document类访问Vector，该类位于另一个函数newAsteroid内的函数timerFunction内，如下所示：

        function timerFunction(e: TimerEvent): void {
          // some more code

            function newAsteroid(): void {

                var idx2: int = Math.floor(Math.random() * colorThemes.length);
                for (var i: int = 0; i <= 10000; i++) {

                    var idx: int = Math.floor(Math.random() * colorThemes[idx2].length);

                    asteroid = new Asteroid();
                    asteroid.x = (Math.random() * (stage.stageWidth - 200) + 100);
                    asteroid.y = (Math.random() * (stage.stageHeight - 100) + 50);

                    asteroid.graphics.lineStyle();
                    //var thiscolorVector: Array = [colorThemes[idx2][idx], colorThemes[idx2][idx]];
                    //var thisGradientArray: Array = [1, -20];
                    //var thisRatiosArray: Array = [0, 250];
                    //asteroid.graphics.beginGradientFill("radial", thiscolorVector, thisGradientArray, thisRatiosArray);
                    asteroid.graphics.beginFill(colorThemes[idx2][idx], dim);
                    asteroid.graphics.drawRect(-1, -1, 2, 2);
                    addChild(asteroid);

                    asteroids.push(asteroid);
                }
            }
...

任何人都可以看到我如何摆脱这些错误并制作多维色彩主题矢量？

注意：

我真的不认为问题在于我构建Vector的方式。我只是在另一个.fla文件中尝试过，它运行得很好。所以问题必须在于我如何尝试访问它或我试图从哪里访问它？

Answer 1

您在类中编写代码，因此您需要在某个方法中执行此操作。一个选项如下：

public class Document extends MovieClip {
    var colorThemes:Vector.<Vector.<uint>> = initColorThemes();

    public function initColorThemes():Vector.<Vector.<uint>> {
        var output:Vector.<Vector.<uint>> = new Vector.<Vector.<uint>>(3);
        output[0] = new Vector.<uint>(5);
        output[1] = new Vector.<uint>(5);
        output[2] = new Vector.<uint>(5);
        output[0][0] = 0xb26002;
        return output;
    }

Answer 2

该属性在主类中声明（我的是public class Document extends MovieClip {），然后必须在函数内部填充，就像标记为“已接受”的答案中所示。我以为我会发布这个，因为Petr Hrehorovsky的例子由于某些原因对我不起作用。最后，当我重新阅读this大约1120个错误时，所有这些都被点击了。

package {
    public class Document extends MovieClip {

        // the property has to go here!  But not the values!
        var colorThemes:Vector.<Vector.<uint>> = new Vector.<Vector.<uint>>(3); 

        public function Document() {

            // declare the "internal" vectors
            colorThemes[0] = new Vector.<uint>(5); // now I can make the "internal" vectors without an 1120 error
            colorThemes[1] = new Vector.<uint>(5); // because colorThemes has been declared
            colorThemes[2] = new Vector.<uint>(5); // as a property of Document class.

            colorThemes[0][0] = 0xb26002; // These also work now because colorThemes has been declared 
            colorThemes[0][1] = 0xff9720;
            colorThemes[0][2] = 0xff8b07;  
            colorThemes[0][3] = 0x007eb2;
            colorThemes[0][4] = 0x07b6ff;
            colorThemes[1][0] = 0xdc45ff;
            colorThemes[1][1] = 0x733fe8;
            colorThemes[1][2] = 0x23a8e8;
            colorThemes[1][3] = 0x26ffd9;
            colorThemes[1][4] = 0x3359ff;
            colorThemes[2][0] = 0x2eccc9;
            colorThemes[2][1] = 0x3d9998;
            colorThemes[2][2] = 0x00ff6b;
            colorThemes[2][3] = 0xff3b6c;
            colorThemes[2][4] = 0xcc14a0;
