我有一个 AnimatedSprite 作为播放器,我正在使用 IAccelerometerListener 来回移动到播放器。问题是即使设备放在桌子上没有任何移动,我的播放器也会向上或向右移动。
谁能指出我错过了什么。下面是我的代码。
public Scene onLoadScene() {
.....
physicsWorld = new PhysicsWorld(new Vector2(0, SensorManager.GRAVITY_EARTH), false);
/** for POTRAIT */
final Display display = getWindowManager().getDefaultDisplay();
int cameraWidth = display.getWidth();
int cameraHeight = display.getHeight();
final Shape ground = new Rectangle(0,cameraHeight, CAMERA_WIDTH,0);
final Shape roof = new Rectangle(0,cameraHeight - (player.getHeight() * 2) , CAMERA_WIDTH, player.getHeight() / 2);
final Shape left = new Rectangle(0,0, 2,cameraHeight);
final Shape right = new Rectangle(cameraWidth , 0, 2, cameraHeight);
final FixtureDef wallFixtureDef = PhysicsFactory.createFixtureDef(0, 0, 1);
PhysicsFactory.createBoxBody(this.physicsWorld, ground, BodyType.StaticBody, wallFixtureDef);
PhysicsFactory.createBoxBody(this.physicsWorld, roof, BodyType.StaticBody, wallFixtureDef);
PhysicsFactory.createBoxBody(this.physicsWorld, left, BodyType.StaticBody, wallFixtureDef);
PhysicsFactory.createBoxBody(this.physicsWorld, right, BodyType.StaticBody, wallFixtureDef);
this.mMainScene.attachChild(ground);
this.mMainScene.attachChild(roof);
this.mMainScene.attachChild(left);
this.mMainScene.attachChild(right);
mMainScene.registerUpdateHandler(physicsWorld);
final Body grd = PhysicsFactory.createBoxBody(physicsWorld, player, BodyType.DynamicBody, FIXTURE_DEF);
this.mMainScene.attachChild(player);
physicsWorld.registerPhysicsConnector(new PhysicsConnector(player,grd, true, true));
}
