andEngineを使ってスプライトのボディを移動する方法は？

Question

スプライトの本体をラインのある部分に沿って移動させたいのですが、スプライトだけを動かすことはできますが、ボディは動いていません。

public Scene onLoadScene() { 
    this.mEngine.registerUpdateHandler(new FPSLogger()); 
    final Scene scene = new Scene(2); 
    scene.setBackground(new ColorBackground(0.09804f, 0.00274f, 0.0784f)); 
    this .enableAccelerometerSensor(this); 
    this.sPhysicsWorld = new PhysicsWorld(new Vector2(0, SensorManager.GRAVITY_EARTH), false); 
    final Shape ground = new Rectangle(0, CAMERA_HEIGHT - 2, CAMERA_WIDTH,2); 
    final Shape roof = new Rectangle(0, 0, CAMERA_WIDTH, 2); 
    final Shape left = new Rectangle(0, 0, 2, CAMERA_HEIGHT); 
    final Shape right = new Rectangle(CAMERA_WIDTH-2, 0,2, CAMERA_HEIGHT); 


    PhysicsFactory.createBoxBody(this.sPhysicsWorld, ground, 
      BodyType.StaticBody, wallFixtureDef); 
    PhysicsFactory.createBoxBody(this.sPhysicsWorld, roof, 
      BodyType.StaticBody, wallFixtureDef);

      BodyType.StaticBody, wallFixtureDef); 
    PhysicsFactory.createBoxBody(this.sPhysicsWorld, right, 
      BodyType.StaticBody, wallFixtureDef); 
    scene.getFirstChild().attachChild(ground); 
    scene.getFirstChild().attachChild(roof); 
    scene.getFirstChild().attachChild(left); 
    scene.getFirstChild().attachChild(right); 

    final int centerX = (CAMERA_WIDTH - this.mFaceTextureRegion.getWidth())/2; 
    final int centerY = (CAMERA_HEIGHT - this.mFaceTextureRegion.getHeight())/2; 
    final AnimatedSprite face = new AnimatedSprite(centerX - 100, centerY, this.mFaceTextureRegion); 
    final Body bodyRedBall = PhysicsFactory.createCircleBody(this.sPhysicsWorld, face, 
      BodyType.DynamicBody, wallFixtureDef); 
    this.sPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(face, bodyRedBall, true, true)); 
    scene.attachChild(face); 

    final AnimatedSprite face2 = new AnimatedSprite(100, 100, this.mFaceTextureRegion); 
    final Body bodyRedBall2 = PhysicsFactory.createCircleBody(this.sPhysicsWorld, face2, 
      BodyType.KinematicBody, wallFixtureDef); 
    final Path path4 = new Path(3).to(682, 223).to(482, 223).to(682, 223); 

    face2.registerEntityModifier(new LoopEntityModifier(new PathModifier(30, path4, null, new IPathModifierListener() { 
      @Override 
      public void onWaypointPassed(final PathModifier pPathModifier, final IEntity pEntity, final int pWaypointIndex) {    
      } 
     }))); 
    this.sPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(face2, bodyRedBall2, true, true){ 
     @Override 
     public void onUpdate(final float pSecondsElapsed) { 
       super.onUpdate(pSecondsElapsed); 
       face2.setPosition(face2.getX(), face2.getY()); 
     } 
}); 


     scene.attachChild(face2);   
    scene.registerUpdateHandler(this.sPhysicsWorld); 
    return scene; 
} 

@Override 
public void onLoadComplete() { 
} 

@Override 
public void onAccelerometerChanged(AccelerometerData pAccelerometerData) { 
    // TODO Auto-generated method stub 
    final Vector2 gravity = Vector2Pool.obtain(pAccelerometerData.getY(), pAccelerometerData.getX()); 
    this.sPhysicsWorld.setGravity(gravity); 
    Vector2Pool.recycle(gravity); 
} 

Answer 1

のsetTransformに

yourBody.setTransform(new Vector2(x/32,y/32), 0); 

を使用すると、あなたはあなたが体を動かすためにbody.setLinearVelocity();を使用することができます32

Answer 2

で、xとyのデフォルトを分割する必要があることを忘れてはならない体を動かすために、スプライトフィジックスコネクタを指定したため、自動的にボディに追従します。

Answer 3

あなたも

yourBody.setTransform(x/32,y/32), 0);

行くことができるとBOX2Dをピクセル単位で動作していないので、あなたは、あなたが32の

Answer 4

public class MoveBodyModifier extends MoveModifier { 

private Body mBody; 

public MoveBodyModifier(float pDuration, float pFromX, float pToX, float pFromY, float pToY, Body body) { 
    super(pDuration, pFromX, pToX, pFromY, pToY); 
    mBody = body; 
} 

@Override 
protected void onSetInitialValues(IEntity pEntity, float pX, float pY) { 
    mBody.setTransform(pX/ PhysicsConnector.PIXEL_TO_METER_RATIO_DEFAULT, 
      pY/ PhysicsConnector.PIXEL_TO_METER_RATIO_DEFAULT, mBody.getAngle()); 
} 

@Override 
protected void onSetValues(IEntity pEntity, float pPercentageDone, float pX, float pY) { 
    mBody.setTransform(pX/ PhysicsConnector.PIXEL_TO_METER_RATIO_DEFAULT, 
      pY/ PhysicsConnector.PIXEL_TO_METER_RATIO_DEFAULT, mBody.getAngle()); 
} 
}
