Рисование Slick2D и Fizzy Physics Engine

/ 31 марта 2012

Я столкнулся с одной проблемой при попытке нарисовать Fizzy с помощью Slick2D.Я думаю, что рисую плохо, потому что я не знаю, в чем еще может быть проблема.

Вот видео с моей работающей программой: http://www.youtube.com/watch?v=Q5THJ54hHBw

А вот код:

import org.jbox2d.common.Vec2;
import org.newdawn.fizzy.DynamicBody;
import org.newdawn.fizzy.Rectangle;
import org.newdawn.fizzy.StaticBody;
import org.newdawn.fizzy.World;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.Image;
import org.newdawn.slick.Input;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.state.BasicGameState;
import org.newdawn.slick.state.StateBasedGame;


public class GameplayState extends BasicGameState {
private World world;
private Rectangle floorShape;
private StaticBody floorBody;


private Rectangle manShape;
private DynamicBody manBody;

private Rectangle o1Shape;
private DynamicBody o1Body;

private Rectangle o2Shape;
private DynamicBody o2Body;


private Image podeaua;
private Image om;
private Image obs;

private int dir = 1;

private int stateID;

SlickDebugDraw sDD;

public GameplayState(int stateID) {
    this.stateID = stateID;
}

@Override
public void init(GameContainer container, StateBasedGame game)
        throws SlickException {
    world = new World(new Vec2(0, 10));
    floorShape = new Rectangle(800, 30);
    floorBody = new StaticBody(floorShape, 0, 570);
    floorBody.setRestitution(0);

    manShape = new Rectangle(30,30);
    manBody = new DynamicBody(manShape, 400, 530);
    manBody.setRestitution(0);

    o1Shape = new Rectangle(30,30);
    o1Body = new DynamicBody(o1Shape, 350, 530);
    o1Body.setRestitution(0);

    o2Shape = new Rectangle(30,30);
    o2Body = new DynamicBody(o2Shape, 460, 530);
    o2Body.setRestitution(0);

    podeaua = new Image("data/podeaua.jpg");
    om = new Image("data/om.jpg");
    obs = new Image("data/obs.jpg");



    world.add(floorBody);
    world.add(manBody);
    world.add(o1Body);
    world.add(o2Body);


}

@Override
public void render(GameContainer container, StateBasedGame game, Graphics g)
        throws SlickException {
    g.drawImage(podeaua,
            floorBody.getX(),
            floorBody.getY());

    g.drawImage(om,
            manBody.getX(),
            manBody.getY());

    g.drawImage(obs,
            o1Body.getX(),
            o1Body.getY());

    g.drawImage(obs,
            o2Body.getX(),
            o2Body.getY());

}

@Override
public void update(GameContainer container, StateBasedGame game, int delta)
        throws SlickException {
    Input input = container.getInput();
    if(input.isKeyDown(Input.KEY_A)){
        manBody.setVelocity(-10, manBody.getYVelocity());
    } else if(input.isKeyDown(Input.KEY_D)){
        manBody.setVelocity(10, manBody.getYVelocity());
    } else {
        manBody.setVelocity(0, manBody.getYVelocity());
    }
    if(input.isKeyDown(Input.KEY_W) && manBody.isTouching(floorBody))
    {
        manBody.applyImpulse(0, -2000);
    }
    if(input.isMouseButtonDown(input.MOUSE_LEFT_BUTTON)) {
        manBody.setAngularVelocity(0);
        manBody.setRotation(0);
    }
    if(input.isMouseButtonDown(input.MOUSE_RIGHT_BUTTON)) {
        manBody.setAngularVelocity(+2f);

    }
    podeaua.setRotation((float) Math.toDegrees(floorBody.getRotation()));
    om.setRotation((float) Math.toDegrees(manBody.getRotation()));
    world.update(delta * 0.001f);
}

@Override
public int getID() {
    // TODO Auto-generated method stub
    return stateID;
}
}
