java - 为我的形状动画java创建一个循环

问题描述

这是来自一个专注于继承的实验室。虽然我了解代码的所有继承方面，并且我成功地完成了实验，但我现在想创建一个循环来多次运行我的动画。

我提供的代码是一种形状动画（点、线、文本、矩形、正方形、椭圆和圆形），它们彼此继承代码（例如线、文本、矩形、椭圆扩展点；正方形扩展矩形和圆形扩展椭圆）。

总的来说，我想让这段代码的执行效率更高

 * This is an animated picture of an object falling out of one portal into another.
 * The light gray Rectangle represents the beam in which the object transports through.
 * A black Circle represents the object being transported.
 * The two dark gray Ellipses represent the portals.
 * The Squares represent the lights of the portal.

解决方案

改变颜色也许这更好

private void changeColors(List<DrawableObjectList> objList) {

        //distinct square in vetor
        List<Square> squareList = new ArrayList<>();
        objList.stream().filter(r -> r instanceof Square).map (r -> (Square) r).forEach(r-> squareList.add(r));

        //new vetor with new colors
        List<Square> newColors = new ArrayList<>();
        squareList.stream().forEach(r-> newColors.add(squareList.indexOf(r)>1? squareList.get(squareList.indexOf(r)-2):squareList.get(squareList.size()-1)));

        //now is just add new vetor newColors to main vetor objList, you can filter again using this .filter(r -> r instanceof Square).map (r -> (Square) r);
    }
