I'd like to make it so that my code generates a cave system in a game. I'm having trouble with the code; it seems that it makes meshes in the parts inbetween the caves and I don't want a mesh, I want an open area. Here is my code:
package CATest;
import java.awt.Color;
import java.awt.Graphics;
import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class CATest extends JPanel{
static CATest w;
static Random rand=new Random();
JFrame jf=new JFrame();
boolean tileMap[][];
public static void main(String argsp[]){
w=new CATest();
w.jf.add(w);
w.jf.setSize(100,400);
w.jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
w.jf.setVisible(true);
w.tileMap=new boolean[100][400];
for(int x=0;x<w.tileMap.length;x++)
for(int y=0;y<w.tileMap[0].length;y++)
if(rand.nextFloat()<0.7)
w.tileMap[x][y]=true;
for(int step=0;step<7;step++){
boolean newMap[][]=new boolean[100][400];
for(int x=0;x<w.tileMap.length;x++)
for(int y=0;y<w.tileMap[0].length;y++){
int count=0;
if(x-1>=0&&y-1>=0&&x+1<w.tileMap.length&&y+1<w.tileMap[0].length){
if(w.tileMap[x-1][y])
count++;
if(w.tileMap[x+1][y])
count++;
if(w.tileMap[x][y-1])
count++;
if(w.tileMap[x][y+1])
count++;
newMap[x][y]=count<=3;
}
}
w.tileMap=newMap;
}
w.repaint();
}
@Override
public void paintComponent(Graphics g){
for(int x=0;x<tileMap.length;x++)
for(int y=0;y<tileMap[0].length;y++){
if(tileMap[x][y])
g.setColor(Color.black);
else g.setColor(Color.white);
g.drawRect(x,y,1,1);
}
}
}
Here's a picture of what happens:cellular automata As you can see, there is a mesh where there should be a cave. Please, help.
