Unity InputSystem 可以通过以下方式获取键盘输入:
1. 在 Unity 中创建一个 InputAction,并将其与键盘输入绑定。
2. 在 InputAction 中定义一个回调函数,用于处理键盘输入事件。
3. 在回调函数中,可以使用 InputSystem.GetDevice<Keyboard>() 方法获取键盘设备,并使用 Keyboard.current 读取当前键盘输入状态。
4. 通过读取键盘输入状态,可以获取按下的键、释放的键、持续按下的键等信息。
以下是示例代码:
```csharp
using UnityEngine;
using UnityEngine.InputSystem;
public class KeyboardInput : MonoBehaviour
{
private InputAction _keyboardAction;
private void Awake()
{
_keyboardAction = new InputAction(binding: "<Keyboard>/anyKey");
_keyboardAction.performed += OnKeyboardInput;
_keyboardAction.Enable();
}
private void OnKeyboardInput(InputAction.CallbackContext context)
{
var keyboard = InputSystem.GetDevice<Keyboard>();
if (keyboard == null)
{
return;
}
if (keyboard.anyKey.wasPressedThisFrame)
{
Debug.Log("A key was pressed.");
}
else if (keyboard.anyKey.wasReleasedThisFrame)
{
Debug.Log("A key was released.");
}
else if (keyboard.anyKey.isPressed)
{
Debug.Log("A key is being held down.");
}
}
}
```
