问题描述
我想移动精灵的身体随着线线的某一部分，只是我能只移动精灵，但身体不动。
公共场景onLoadScene（）{
this.mEngine.registerUpdateHandler（新FPSLogger（））;
最后一幕一幕=新场景（2）;
scene.setBackground（新ColorBackground（0.09804f，0.00274f，0.0784f））;
这.enableAccelerometerSensor（本）;
this.sPhysicsWorld =新PhysicsWorld（新Vector2（0，SensorManager.GRAVITY_EARTH），FALSE）;
最终形状地面=新的Rectangle（0，CAMERA_HEIGHT - 2，CAMERA_WIDTH，2）;
最终形状的屋顶=新的Rectangle（0，0，CAMERA_WIDTH，2）;
最终形状左=新的Rectangle（0，0，2，CAMERA_HEIGHT）;
最终形状右=新的Rectangle（CAMERA_WIDTH-2，0,2，CAMERA_HEIGHT）;
PhysicsFactory.createBoxBody（this.sPhysicsWorld，地面，
BodyType.StaticBody，wallFixtureDef）;
PhysicsFactory.createBoxBody（this.sPhysicsWorld，屋顶，
BodyType.StaticBody，wallFixtureDef）;
PhysicsFactory.createBoxBody（this.sPhysicsWorld，左，
BodyType.StaticBody，wallFixtureDef）;
PhysicsFactory.createBoxBody（this.sPhysicsWorld吧，
BodyType.StaticBody，wallFixtureDef）;
scene.getFirstChild（）attachChild（地）。
scene.getFirstChild（）attachChild（屋顶）。
scene.getFirstChild（）attachChild（左）。
scene.getFirstChild（）attachChild（右）。
最终诠释的centerX =（CAMERA_WIDTH - this.mFaceTextureRegion.getWidth（））/ 2;
最终诠释centerY =（CAMERA_HEIGHT - this.mFaceTextureRegion.getHeight（））/ 2;
最后AnimatedSprite面=新AnimatedSprite（的centerX - 100，centerY，this.mFaceTextureRegion）;
最后身体bodyRedBall = PhysicsFactory.createCircleBody（this.sPhysicsWorld，脸，
BodyType.DynamicBody，wallFixtureDef）;
this.sPhysicsWorld.registerPhysicsConnector（新PhysicsConnector（面部，bodyRedBall，真，真））;
scene.attachChild（面）;
最后AnimatedSprite face2 =新AnimatedSprite（100，100，this.mFaceTextureRegion）;
最后身体bodyRedBall2 = PhysicsFactory.createCircleBody（this.sPhysicsWorld，face2，
BodyType.KinematicBody，wallFixtureDef）;
最终路径path4 =新路径（3）。为（682，223）。为了（482，223）。为了（682，223）;
face2.registerEntityModifier（新LoopEntityModifier（新PathModifier（30，path4，空，新IPathModifierListener（）{
@覆盖
公共无效onWaypointPassed（最终PathModifier pPathModifier，最终IEntity pEntity，最终诠释pWaypointIndex）{
}
}）））;
this.sPhysicsWorld.registerPhysicsConnector（新PhysicsConnector（face2，bodyRedBall2，真，真）{
@覆盖
公共无效的OnUpdate（最终浮动pSecondsElapsed）{
super.onUpdate（pSecondsElapsed）;
face2.setPosition（face2.getX（），face2.getY（））;
}
}）;
scene.attachChild（face2）;
scene.registerUpdateHandler（this.sPhysicsWorld）;
返回现场;
}
@覆盖
公共无效的onLoadComplete（）{
}
@覆盖
公共无效onAccelerometerChanged（AccelerometerData pAccelerometerData）{
// TODO自动生成方法存根
最终Vector2比重= Vector2Pool.obtain（pAccelerometerData.getY（），pAccelerometerData.getX（））;
this.sPhysicsWorld.setGravity（重力）;
Vector2Pool.recycle（重力）;
}
解决方案
您可以使用 body.setLinearVelocity（）; 移动身体，精灵会自动跟随身体，因为你已经指定一个物理连接。
I want to move body of the sprite along with line in some portion of line, just i able to move sprite only but body is not moving.
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);
PhysicsFactory.createBoxBody(this.sPhysicsWorld, left,
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);
}
解决方案
You can use body.setLinearVelocity(); to move the body, the sprite will automatically follow the body because you have specified a physics connector.
