我正在尝试使用Jmonkey3 SDk创建fps风格的游戏。我已经从我的角色中创建了一个Node并附加了一个物理角色，然后添加了一个Chase Camera作为我的主要fps视图。向前走，向右走，工作完美。问题是当鼠标到达我看到的模型边缘时不再旋转。此外，相机没有保持fps的正确位置。
基本上相机和模型节点不能用鼠标正常旋转。此外，他的模特并没有“跟着相机上下。”
// Enable a chase cam for this target (typically the player).
flyCam.setEnabled(false);
chaseCam = new ChaseCamera(cam, model, inputManager);
chaseCam.setDragToRotate(false);
chaseCam.setDefaultDistance(.1f);
chaseCam.setInvertVerticalAxis(true);
chaseCam.setLookAtOffset(new Vector3f(-.3f, 2.1f, -.1f));
chaseCam.setDownRotateOnCloseViewOnly(false);
bulletAppState.getPhysicsSpace().addCollisionListener(this);
