我正在使用Unity 2019.1.4f1，刚刚从软件包管理器中获得了新的Unity输入系统。我无法在要使用它的单行为中看到用于链接生成的C＃类的序列化字段。
我已经公开并将[SerializeField]属性添加到实例，但是它不会在检查器中显示该字段。 因此，我尝试在Monobehavior内部以编程方式创建实例，但无法正常工作。我的SelectDestination方法没有被调用
public class PlayerInputManager : MonoBehaviour
{
[SerializeField]
public PlayerInput Input;
private void Awake()
{
Input = new PlayerInput();
Input.Enable();
}
void OnEnable()
{
Input.Player.SelectDestination.performed += ctx => SelectDestination();
Input.Player.SelectTarget.performed += ctx => SelectDestination();
Input.Player.W.performed += ctx => SelectDestination();
Input.Player.Enable();
}
void OnDisable()
{
Input.Player.SelectDestination.performed -= ctx => SelectDestination();
Input.Player.SelectTarget.performed -= ctx => SelectDestination();
Input.Player.W.performed -= ctx => SelectDestination();
Input.Player.Disable();
}
void SelectDestination()
{
Debug.Log("BLA");
}
}
在按下W，左键单击或右键单击时，应记录“ BLA”
如果要使用此功能，Unity会从我的播放器输入导入设置中生成以下代码：

以编程方式创建实例的方式起作用。
public class PlayerInputManager : MonoBehaviour
{
[SerializeField]
public PlayerInput Input;
private void Awake()
{
Input = new PlayerInput(); <<<<<<<<<<<
Input.Enable();
}
...
}
唯一的问题是未激活输入后端。重新启动Unity后，会弹出一条消息以解决此问题，此后它仍然起作用。导入新的输入系统时，也会更改此后端选项，但我设法以某种方式单击了未更改
