Unity ushort
时间: 2024-05-29 08:10:09 浏览: 15
Unity ushort is a data type used in Unity game engine for storing integer values that range from 0 to 65,535. It is a 16-bit unsigned integer, meaning that it can only store positive values and cannot store negative values. It is commonly used for storing IDs, indices, and other small numerical values in Unity game development. The ushort data type is more memory-efficient compared to other data types such as int or float, making it a preferred choice for game developers who need to optimize their game's performance.

Unity RegisterRawInputDevices
在Unity中,无法直接使用`RegisterRawInputDevices`函数来注册原始输入设备。但是,你可以通过使用Windows API和Unity的插件来实现。
以下是一个示例代码,展示如何在Unity中注册原始输入设备:
```csharp
using UnityEngine;
using System;
using System.Runtime.InteropServices;
public class RawInputRegistration : MonoBehaviour
{
[DllImport("user32.dll")]
private static extern bool RegisterRawInputDevices(ref RAWINPUTDEVICE pRawInputDevices, uint uiNumDevices, uint cbSize);
// Constants for input device types
private const ushort RIM_TYPEMOUSE = 0x0000;
private const ushort RIM_TYPEKEYBOARD = 0x0001;
private const ushort RIM_TYPEHID = 0x0002;
// Constants for raw input flags
private const uint RIDEV_INPUTSINK = 0x00000100;
private const uint RIDEV_NOLEGACY = 0x00000030;
// Structure for raw input device
[StructLayout(LayoutKind.Sequential)]
private struct RAWINPUTDEVICE
{
public ushort usUsagePage;
public ushort usUsage;
public uint dwFlags;
public IntPtr hwndTarget;
}
private void Start()
{
RegisterRawInputDevicesForMouse();
RegisterRawInputDevicesForKeyboard();
}
private void RegisterRawInputDevicesForMouse()
{
RAWINPUTDEVICE mouseDevice = new RAWINPUTDEVICE();
mouseDevice.usUsagePage = 0x01; // Generic desktop controls
mouseDevice.usUsage = 0x02; // Mouse
mouseDevice.dwFlags = RIDEV_INPUTSINK; // Receive input even when not in the foreground
mouseDevice.hwndTarget = IntPtr.Zero; // Null hwndTarget to receive input from all windows
if (!RegisterRawInputDevices(ref mouseDevice, 1, (uint)Marshal.SizeOf(mouseDevice)))
{
Debug.LogError("Failed to register raw input device for mouse.");
}
}
private void RegisterRawInputDevicesForKeyboard()
{
RAWINPUTDEVICE keyboardDevice = new RAWINPUTDEVICE();
keyboardDevice.usUsagePage = 0x01; // Generic desktop controls
keyboardDevice.usUsage = 0x06; // Keyboard
keyboardDevice.dwFlags = RIDEV_INPUTSINK | RIDEV_NOLEGACY; // Receive input even when not in the foreground, and disable legacy keyboard messages
keyboardDevice.hwndTarget = IntPtr.Zero; // Null hwndTarget to receive input from all windows
if (!RegisterRawInputDevices(ref keyboardDevice, 1, (uint)Marshal.SizeOf(keyboardDevice)))
{
Debug.LogError("Failed to register raw input device for keyboard.");
}
}
}
```
这段代码在Unity中注册了鼠标和键盘的原始输入设备。请注意,这个示例只是一个起点,你可能需要根据你的具体需求进行相应的修改和扩展。
重要提示:使用Windows API函数需要在Unity项目中启用`unsafe`代码,并且在构建项目时选择为Windows平台。此外,这些代码只能在Windows平台上运行,无法在其他平台上使用。
Unity中使用GetRawInputData
在Unity中,要使用GetRawInputData函数获取原始输入数据,你需要使用Windows的原生API来实现。下面是一个示例代码,展示了如何在Unity中使用GetRawInputData函数:
```csharp
using System;
using System.Runtime.InteropServices;
using UnityEngine;
public class RawInputExample : MonoBehaviour
{
[StructLayout(LayoutKind.Sequential)]
public struct RAWINPUTDEVICE
{
public ushort usUsagePage;
public ushort usUsage;
public uint dwFlags;
public IntPtr hwndTarget;
}
[StructLayout(LayoutKind.Sequential)]
public struct RAWINPUTHEADER
{
public uint dwType;
public uint dwSize;
public IntPtr hDevice;
public IntPtr wParam;
}
[DllImport("user32.dll")]
public static extern bool RegisterRawInputDevices([MarshalAs(UnmanagedType.LPArray, SizeParamIndex = 0)] RAWINPUTDEVICE[] pRawInputDevices, uint uiNumDevices, uint cbSize);
[DllImport("user32.dll")]
public static extern uint GetRawInputData(IntPtr hRawInput, uint uiCommand, IntPtr pData, ref uint pcbSize, uint cbSizeHeader);
const int RIDEV_INPUTSINK = 0x00000100;
const int RID_INPUT = 0x10000003;
void Start()
{
RAWINPUTDEVICE[] devices = new RAWINPUTDEVICE[1];
devices[0].usUsagePage = 0x01; // Generic desktop controls
devices[0].usUsage = 0x06; // Keyboard
devices[0].dwFlags = RIDEV_INPUTSINK;
devices[0].hwndTarget = IntPtr.Zero;
if (!RegisterRawInputDevices(devices, (uint)devices.Length, (uint)Marshal.SizeOf(dev
