有很多像这样的问题,但我检查了所有问题,但都没有解决我遇到的问题,因此请不要将它作为重复项来关闭。在java中使用圆圈进行碰撞检测
我正在制作一个中间有一个大圆圈的游戏,周围是六个其他圈子,这些圈子的大小逐渐增加。如果六圈中的一圈与中央圈发生碰撞,我想结束比赛。任何人都能提供合适的解决方案
这里是我的代码:
package virus;
import java.awt.*;
import java.util.Random;
import javax.swing.JPanel;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
public class VirusGamePanel extends JPanel implements MouseListener{
private static final long serialVersionUID = 1L;//serialVersionUID field
Random colour = new Random();//the outside ovals will always be a random colour
private int sizeX1 = 0;//the x size of the outside ovals
private int sizeX2 = 0;
private int sizeX3 = 0;
private int sizeX4 = 0;
private int sizeX5 = 0;
private int sizeX6 = 0;
private int sizeY1 = 0;//the y size of the outside ovals
private int sizeY2 = 0;
private int sizeY3 = 0;
private int sizeY4 = 0;
private int sizeY5 = 0;
private int sizeY6 = 0;
int score = 0;
static String scorestring = "Score: ";
Color rand = new Color(colour.nextInt(255), colour.nextInt(255), colour.nextInt(255)); //generate the random colour
public void paint(Graphics g)
{
super.paint(g);
g.setColor(Color.magenta);
g.drawString(scorestring+score,275,250);
g.setColor(Color.orange);
g.drawOval(200, 150, 200, 200);
g.setColor(rand);
g.fillOval(300 - sizeX1/2, 50 - sizeY1/2, sizeX1, sizeY1);//these six ovals are supposed to increase in size
g.fillOval(130 - sizeX2/2,100 - sizeY2/2, sizeX2, sizeY2);
g.fillOval(480 - sizeX3/2,100 - sizeY3/2, sizeX3, sizeY3);
g.fillOval(130 - sizeX4/2,400 - sizeY4/2, sizeX4, sizeY4);
g.fillOval(480 - sizeX5/2,400 - sizeY5/2, sizeX5, sizeY5);
g.fillOval(305 - sizeX6/2,450 - sizeY6/2, sizeX6, sizeY6);
try
{
Thread.sleep(100);
}
catch(InterruptedException e)
{
e.printStackTrace();
}
inc();
}
private void inc()//increase the size of the ovals
{
sizeX1++;
sizeY1++;
sizeX2++;
sizeY2++;
sizeX3++;
sizeY3++;
sizeX4++;
sizeY4++;
sizeX5++;
sizeY5++;
sizeX6++;
sizeY6++;
repaint();
}
public static void main(String[] args) {}
当两个圆碰撞,他们的中心之间的距离等于他们的半径之和。另外,如果你创建了一个'Circle'类,你的代码将会大大改善。 – Blender
*“请不要将其作为复本关闭。”*当然。但既然你基本上抛弃了代码,并要求我们为你完成它,我会投票结束“不是真正的问题”。 –
我会在Circle类中包含什么? – imulsion
