由于最近在做游戏魔改很多功能在游戏里面没法实现没错说的就是排行榜所以准备用Unity3D开发一个类似于桌面精灵的功能部件实现效果如下 PS有需要定制的老板请私信联系
要实现这个效果需要分两步
1背景透明
2程序始终在前面 一背景透明实现核心代码
using System;
using System.Runtime.InteropServices;
using UnityEngine;public class TransparentWindow : MonoBehaviour
{[SerializeField]private Material m_Material;private struct MARGINS{public int cxLeftWidth;public int cxRightWidth;public int cyTopHeight;public int cyBottomHeight;}// Define function signatures to import from Windows APIs[DllImport(user32.dll)]private static extern IntPtr GetActiveWindow();[DllImport(user32.dll)]private static extern int SetWindowLong(IntPtr hWnd, int nIndex, uint dwNewLong);[DllImport(Dwmapi.dll)]private static extern uint DwmExtendFrameIntoClientArea(IntPtr hWnd, ref MARGINS margins);// Definitions of window stylesconst int GWL_STYLE -16;const uint WS_POPUP 0x80000000;const uint WS_VISIBLE 0x10000000;void Start(){//return;
#if !UNITY_EDITORvar margins new MARGINS() { cxLeftWidth -1 };// Get a handle to the windowvar hwnd GetActiveWindow();// Set properties of the window// See: https://msdn.microsoft.com/en-us/library/windows/desktop/ms633591%28vvs.85%29.aspxSetWindowLong(hwnd, GWL_STYLE, WS_POPUP | WS_VISIBLE);// Extend the window into the client area//See: https://msdn.microsoft.com/en-us/library/windows/desktop/aa969512%28vvs.85%29.aspx DwmExtendFrameIntoClientArea(hwnd, ref margins);
#endif}// Pass the output of the camera to the custom material// for chroma replacementvoid OnRenderImage(RenderTexture from, RenderTexture to){Graphics.Blit(from, to, m_Material);}} shader代码如下
Shader Custom/ChromakeyTransparent {Properties{_MainTex(Base (RGB), 2D) white {}_TransparentColourKey(Transparent Colour Key, Color) (0,0,0,1)_TransparencyTolerance(Transparency Tolerance, Float) 0.01}SubShader{Pass{Tags{ RenderType Opaque }LOD 200CGPROGRAM#pragma vertex vert#pragma fragment frag#include UnityCG.cgincstruct a2v{float4 pos : POSITION;float2 uv : TEXCOORD0;};struct v2f{float4 pos : SV_POSITION;float2 uv : TEXCOORD0;};v2f vert(a2v input){v2f output;output.pos UnityObjectToClipPos(input.pos);output.uv input.uv;return output;}sampler2D _MainTex;float3 _TransparentColourKey;float _TransparencyTolerance;float4 frag(v2f input) : SV_Target{// What is the colour that *would* be rendered here?float4 colour tex2D(_MainTex, input.uv);// Calculate the different in each component from the chosen transparency colourfloat deltaR abs(colour.r - _TransparentColourKey.r);float deltaG abs(colour.g - _TransparentColourKey.g);float deltaB abs(colour.b - _TransparentColourKey.b);// If colour is within tolerance, write a transparent pixelif (deltaR _TransparencyTolerance deltaG _TransparencyTolerance deltaB _TransparencyTolerance){return float4(0.0f, 0.0f, 0.0f, 0.0f);}// Otherwise, return the regular colourreturn colour;}ENDCG}}
}
将脚本绑定在摄像机上并用该shader创建材质A放到脚本下。
摄像机渲染模式改为只渲染颜色颜色和材质A一样。 二程序始终在前面核心代码
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;public class C
{public delegate bool WNDENUMPROC(IntPtr hwnd, uint lParam);[DllImport(user32.dll, SetLastError true)]public static extern bool EnumWindows(WNDENUMPROC lpEnumFunc, uint lParam);[DllImport(user32.dll, SetLastError true)]public static extern IntPtr GetParent(IntPtr hWnd);[DllImport(user32.dll)]public static extern uint GetWindowThreadProcessId(IntPtr hWnd, ref uint lpdwProcessId);[DllImport(kernel32.dll)]public static extern void SetLastError(uint dwErrCode);public static IntPtr GetProcessWnd(){IntPtr ptrWnd IntPtr.Zero;uint pid (uint)Process.GetCurrentProcess().Id; // 当前进程 ID bool bResult EnumWindows(new WNDENUMPROC(delegate (IntPtr hwnd, uint lParam){uint id 0;if (GetParent(hwnd) IntPtr.Zero){GetWindowThreadProcessId(hwnd, ref id);if (id lParam) // 找到进程对应的主窗口句柄 {ptrWnd hwnd; // 把句柄缓存起来 SetLastError(0); // 设置无错误 return false; // 返回 false 以终止枚举窗口 }}return true;}), pid);return (!bResult Marshal.GetLastWin32Error() 0) ? ptrWnd : IntPtr.Zero;}
} [DllImport(User32.dll)]extern static bool SetForegroundWindow(IntPtr hWnd);[DllImport(User32.dll)]extern static bool ShowWindow(IntPtr hWnd, short State);[DllImport(user32.dll )]public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);static readonly IntPtr HWND_TOPMOST new IntPtr(-1);const UInt32 SWP_NOSIZE 0x0001;const UInt32 SWP_NOMOVE 0x0002;IntPtr hWnd;//public float Wait 0;//延迟执行//public float Rate 1;//更新频率public bool KeepForeground true;//保持最前/// summary/// 激活窗口/// /summaryvoid Active(){if (KeepForeground){ShowWindow(hWnd, 1);SetForegroundWindow(hWnd);SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);}} hWnd C.GetProcessWnd();Active();
三打包设置如下 四优化扩展
步骤和道理同上
