Thank You So Much Stef! You Are A Life Saver!

Thanks Stef
that new updated version worked just fine for me.
and side-scrolling is also smooth
however when i press jump and run than hero jumps smooth but when coming down camera trys to center hero and the hero goes a little back and the scence stops and ruins the smooth-ness

EDIT :: Solved ..
just had to put this line in update method
camera.follow(hero, CameraFollowStyle.TOPDOWN);

Thanks a lot for this awesome library

Hi all. Im following the tutorials on the ME wiki and Im stuck at the input tutorial - it doesnt work for me in the Player and Level class - it only works in the HelloWorld Class using the slick2d methods for input. Can you point out my mistake ? Here are my classes following the tutorials.
[code]
import org.newdawn.slick.AppGameContainer;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.state.StateBasedGame;

/**
* Launch Hello World example
**/
public class HelloWorldTest extends StateBasedGame {

public HelloWorldTest(String title) {
super(title);
}

@Override
public void initStatesList(GameContainer container) throws SlickException {
// add HelloWorld to current game with id 1
addState(new HelloWorld(1, container));
}

public static void main(String[] argv) {
try {
AppGameContainer container = new AppGameContainer(new HelloWorldTest(
"Hello World Marte Engine"));
container.setDisplayMode(800, 600, false);
container.setTargetFrameRate(60);
container.start();

} catch (SlickException e) {
e.printStackTrace();
}
}

}

public HelloWorld(int id, GameContainer container) throws SlickException {
super(id, container);

}


@Override
public void render(GameContainer container, StateBasedGame stateBasedGame, Graphics g)
throws SlickException {
super.render(container,stateBasedGame,g);

g.drawString("Hello World", 300, 200);
img.draw(100, 100, 0.2f);
// if (one) g.drawString("one pressed", 100, 100);
}
