Hi i am trying to create a game in which i need to use drawImage of graphics method outside the paint method.I am trying it in the following way.The code is complilling fine & also not giving any exception but it doesn draw any image.Can anyone help me out??? I am sending some part of this code.

import java.awt.*;
import java.applet.*;
public class MyImage extends Applet
{
Dimension d;
Graphics g1;// this is a variable of graphics object
int x=10;
int y=10;
Image ir,ib,ig,iy,i1;

public void init()
{
getImages();
d = getSize();
setBackground(Color.BLACK);
addKeyListener(this);
}

public void paint(Graphics g)
{
if (g1==null && d.width>0 && d.height>0)
{
i1 = createImage(d.width, d.height); // creating the graphics objetct
g1 = i1.getGraphics();
}
if (g1==null || i1==null)
return;
g.drawImage(ib,100,100,this);
}

public void met()
{
g1.drawImage(ir,50,50,this); //drawing an image with g1(graphics object)
}

public void getImages()
{
ib=getImage(getDocumentBase(),"blue.gif");
ig=getImage(getDocumentBase(),"green.gif");
ir=getImage(getDocumentBase(),"red.gif");
iy=getImage(getDocumentBase(),"yellow.gif");
}

Is it absolutely required that your code be exactly similar to the way you have it written?
Also, is this for an applet or not?
 
It is sorta covered in the JavaRanch Style Guide.
