Adr*_*ian 8 c# transparency image click-through non-interactive
为了给出一些背景知识,我正在开发一款软件,可以帮助玩家玩星球大战:旧共和国.游戏的用户界面功能非常有限,所以我正在开发一个外部应用程序,它将实时解析日志,并输出视觉线索,以帮助用户最大化他们的游戏性能.例如,如果角色获得某个"buff",战斗日志将显示它,我想在屏幕上放置一个视觉线索(因此用户不需要注意周边的小图标)屏幕).
在开始之前,我想为自己创建一些"概念证明"脚本,以弄清楚我将如何处理主要部分.我坚持的是我有问题的地方:
我需要能够在游戏的屏幕上显示一个图形,可能是一个透明的PNG文件.用户需要能够点击该图像,以便他们可以继续与游戏进行交互.我对如何去做有点迷茫.要求是:
任何关于从哪里开始的指导将非常感谢!

我已经开始考虑做一些类似的事情,所以这可能会给你一个开始.
对于第一个版本,你可以通过看"ALLOWTRANSPARENCY"和"TransparencyKey",和"层次最高的"特性开始表格.
(我发现TransparencyKey不适用于White(255,255,255),但是特定的非白色工作正常......不确定原因).
这可以作为一种可以点击其他形式的点击式表格...但由于它是透明的,因此无法在透明部分中显示图像.但是,如果你需要的只是一个适合目标应用程序的hud,这可能是最简单的方法.
如果这个顶级形式不会在游戏前结束......你可能会尝试将游戏置于窗口模式.
在全屏模式下运行时,游戏通常直接通过ActiveX,Direct3D,OpenGL,DirectDraw等绘制到屏幕上.
在这些之上绘图需要将代码注入DirectX,OpenGL或其他引擎的绘制/更新/刷新功能(基本上告诉DirectX3D在每个绘制周期结束时绘制您的东西).有一些现有的软件可以做到这一点:例如,Steam Overlay,fraps,xfire.
一个快速的谷歌搜索发现" 游戏覆盖 ",虽然我没有下载或尝试,说它可以覆盖游戏上的表格应用程序为您.
(似乎那个程序是在一家刚刚解散的公司之下,无论如何我似乎无法让它为我工作......)
可以创建一个不完全透明但通过本机Windows调用可以点击的表单.我会看看是否可以在接下来的几天内创建一个示例.
我找到了一个旧的测试项目,并对其进行了一些清理.
基本上,当它运行时,它将在屏幕的前面绘制500条随机红线,这些红线是可点击的.然后它绘制1000条随机白线(即擦除).然后重复.
在编写代码时,我希望获得一些概念证明:如何能够在表单的整个表面上绘制,如何以编程方式使表单在多个屏幕上变为完整大小,如何使用背景工作者,以及这个概念证明如何作为透明叠加层工作.

Enums列表是在本机Windows调用中使用的值,并将像White这样的RGB颜色转换为uints使得处理本机Windows有点痛苦.
但是,最后,我们现在有一个覆盖所有屏幕的隐形画布,我们可以像任何其他图形对象一样绘制它(所以它就像在线条上一样容易地绘制文本或图片).
(我认为如果你将半透明的图片绘制到图形对象上,那么你可以自己制作半透明的叠加而不是完全不透明/透明的叠加).
此示例不能在全屏3D游戏上放置叠加层,但对于在窗口模式下运行的相同游戏可以正常工作.
(PS我刚刚在Team Fortress 2中对它进行了测试,它在Windowed模式下进行了测试,但不是全屏,所以我猜测旧共和国将是类似的).
以下链接可能对试图挂钩Direct3D版本9,10和11的绘图例程的任何人都有用.
https://github.com/spazzarama/Direct3DHook
它不提供全功能覆盖,但上面的示例项目为我成功地在Team Fortress 2上每秒写入帧.它有关于如何开始使用它的良好说明.它应该指导您完成设置SlimDX Runtime和EasyHook的过程.
我过去这样做的方法是获取主窗口的句柄，通常唯一的方法是遍历整个窗口列表，查找具有所需标题的窗口。如果同时打开两个具有相同标题的游戏实例，就会出现问题。
获得该窗口句柄后，您可以通过指定超出多少像素、向下多少像素以及希望其相对的“输出”层数（z 索引），在现有内容的顶部添加视觉元素到窗口的左上角像素。
实现多窗口的一种方法是启动 C# 程序，查看是否有正在玩的游戏实例，发出一条消息，如果有则终止，如果没有，则启动您自己的游戏实例一个子进程。我想你当时可以找回hwin，但如果没有的话你可以在游戏运行后在窗口列表中搜索目标标题。
