我正在使用LibGdx和Tiled,当在屏幕上移动时,游戏上会出现水平和垂直线条.如有必要,我可以发布您需要的任何代码.如何让这些线路停止？

这是一个小的bitbucket存储库,尽可能小,它有相同的故障:

我有一个JComboBox有12个不同的选择,根据选择的内容,我希望问题(JLabel)更改匹配选择.我已经尝试了一个if语句来查看所选内容以及它是否与应该选择的内容相匹配,然后问题会相应地改变,但JLabel在某种情况下从未真正改变过.

码

import java.awt.*;
import java.awt.event.*;
import java.awt.image.BufferedImage;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.*;

public class Window extends JFrame{
    private static final long serialVersionUID = 1L;
    public Window(){
        super("Area Finder v1.0");
        BufferedImage image = null;

        try {
            image = ImageIO.read(getClass().getClassLoader().getResource("images/areafinder.png"));
        } catch (IOException e) {
            e.printStackTrace();
        }
        super.setIconImage(image);
        setSize(400, 500);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        JPanel panel = new JPanel();
        JLabel Instr = new JLabel("What would kind of area would you like to find?");
        String[] areaChoices = {"Circle", "Square", "Rectangle", "Triangle", "Trapezoid", "Parallelogram", …

我试图自己调试这个,但我无法弄清楚!在运行我的代码时,我有时会遇到分段错误,当没有seg错误时,它运行得很好并且有效.任何指导将不胜感激,谢谢!另外,请记住我是C++的新手.

这是我到目前为止所拥有的:

#include <iostream>
#include <vector>
using namespace std;

vector<int> selection_sort(vector<int> numbers) {
    int lowest_number_index;
    int lowest_number;
    int starting_size = numbers.size();
    vector<int> sorted_numbers;
    for (int i = 0; i < numbers.size(); ++i) {

        // Find the lowest number
        if (numbers[i] <= lowest_number) {
            lowest_number_index = i;
            lowest_number = numbers[lowest_number_index];
        }

        // Found it! Now let's add it to the other array
        // and remove it from this one.
        if (i == numbers.size() - 1 && numbers.size() != 1) {
            sorted_numbers.push_back(lowest_number); …

我希望这是有道理的,但是我正在尝试用Java制作一个蛇式游戏,如果你同时按两个方向/太快,那么蛇就会自动消失.例如,如果你向下跑,然后向右击,那么你就会让蛇在同一列上直接上升并自杀,但它应该向右然后向上.如果有人能帮助我,那就太好了,谢谢!
