Godot Windows平台如何自动处理鼠标穿透

可以利用DllImport导入SetWindowLong来设置窗口样式

具体代码:

WindowsApiManager.cs

using System.Runtime.InteropServices;
using Godot;

public partial class WindowsApiManager : Node
{
 private nint _hWnd;

 [DllImport("user32.dll")]
 public static extern nint GetActiveWindow();

 [DllImport("user32.dll")]
 private static extern int SetWindowLong(nint hWnd, int nIndex, uint dwNewLong);

 public override void _Ready()
 {
 _hWnd = GetActiveWindow();
 _ = SetWindowLong(_hWnd, -20, 524416u);
 }

 public void SetClickThrough(bool clickthrough)
 {
 if (clickthrough)
 {

 _ = SetWindowLong(_hWnd, -20, 524448u);
 }
 else
 {
 _ = SetWindowLong(_hWnd, -20, 524416u);
 }
 }
}

MouseDetection.cs

using Godot;

public partial class MouseDetection : Node
{
 private WindowsApiManager _api;

 private bool _clickthrough = true;

 public override void _Ready()
 {
 _api = GetNode<WindowsApiManager>("/root/WindowsApiManager");
 _api.SetClickThrough(clickthrough: true);
 }

 public override void _PhysicsProcess(double _)
 {
 DetectPassthrough();
 }

 private void DetectPassthrough()
 {
 Viewport viewport = GetViewport();
 Image img = viewport.GetTexture().GetImage();
 Rect2 rect = viewport.GetVisibleRect();
 Vector2 mousePosition = viewport.GetMousePosition();
 int viewX = (int)((int)mousePosition.X + rect.Position.X);
 int viewY = (int)((int)mousePosition.Y + rect.Position.Y);
 int x = (int)(img.GetSize().X * viewX / rect.Size.X);
 int y = (int)(img.GetSize().Y * viewY / rect.Size.Y);
 if (x < img.GetSize().X && x >= 0 && y < img.GetSize().Y && y >= 0)
 {
 SetClickability(img.GetPixel(x, y).A >= 1f);
 }
 img.Dispose();
 }

 private void SetClickability(bool clickable)
 {
 if (clickable != _clickthrough)
 {
 _clickthrough = clickable;
 _api.SetClickThrough(!clickable);
 }
 }
}

使用方法:

将WindowsApiManager.cs设为自动加载脚本
