getRGB() causing problem!

[Nitesh Panchal]

here is the code

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.BufferedImage;

public class Snowfall extends Applet implements Runnable{
	Thread t;
	int width,height;
	BufferedImage buffer;
	Graphics gfx;
	boolean flag;
	int LineCol;
	class Snow{
		public Point p;
		public int yinc;
	}
	Snow[] s;
	public void init(){
		s = new Snow[500];
		setSize(790,510);
		flag = true;
		Color red = new Color(255,0,0);
		LineCol = red.getRGB();	
		
		height = getHeight();
		width = getWidth();
		setBackground(Color.BLACK);
		setForeground(Color.WHITE);
		buffer = new BufferedImage(width,height,BufferedImage.TYPE_INT_RGB);
		gfx = buffer.getGraphics();
		for(int i = 0;i < s.length; i++){
			s[i] = new Snow();
			s[i].p = new Point();
			buildsnow(i);
		}
		flag = false;
		t = new Thread(this);
		t.start();
	}
	public void buildsnow(int i){
		s[i].p.x = 10+ (int)(Math.random()*width);
		if(flag){
			s[i].p.y = (int)(Math.random()*height);
		}
		else
			s[i].p.y = 2;
			s[i].yinc = 2;
	}
	public void run(){
		while(true){
			repaint();
			try{
				Thread.sleep(10);
			}
			catch(InterruptedException ex){
			}
		}
	}
	public void update(Graphics g){
		paint(g);
	}
	public void paint(Graphics g){
		gfx.clearRect(0,0,width,height);
		gfx.setColor(Color.RED);
		for (int i = 1; i <= 5;i++){
			gfx.drawLine(200,180+i,320,250+i);
			gfx.drawLine(200,180+i,320,250+i);
			
		}
		for (int i = 0; i<s.length ;i++){
			gfx.drawLine(s[i].p.x,s[i].p.y,s[i].p.x,s[i].p.y);
			s[i].p.y+=s[i].yinc;
			if(s[i].p.y >= height)
				buildsnow(i);
			else{
				int x = s[i].p.x;
				int y = s[i].p.y+2;
				if ( buffer.getRGB(x,y)==LineCol){
					if(buffer.getRGB(x+2,y)==LineCol){
						s[i].p.x-=2;
					}
					else
						s[i].p.x+=2;
				}
			}
		}
		g.drawImage(buffer,0,0,this);
	}
}

when i omit getRGB() method it works fine else it doesn't . Can anybody suggest me what is the problem?

[Nitesh Panchal]

why no replies?

[Paul Clapham]

Probably because you haven't described the problem. You didn't say what constituted "works fine" and "doesn't". You didn't post any error messages or say whether any errors occurred. The problem could even be that one version of the code didn't compile for all we can tell. You need to provide details.

[Nitesh Panchal]

No error is caused as such but the applet isn't executing. if i omit this code then it works fine

else{   
                int x = s[i].p.x;   
                int y = s[i].p.y+2;   
                if ( buffer.getRGB(x,y)==LineCol){   
                    if(buffer.getRGB(x+2,y)==LineCol){   
                        s[i].p.x-=2;   
                    }   
                    else   
                        s[i].p.x+=2;   
                }   
            }   

the problem is only with the above snippet

[Ulf Dittmer]

We still don't know what "the problem" is. Have you checked the Java Console for error messages? What are you expecting to happen, and what is actually happening? TellTheDetails
