除非我添加延迟，否则 SendInput 在游戏中不起作用.为什么? [英] SendInput doesn't work in a game unless I add delays. Why?
本文介绍了除非我添加延迟，否则 SendInput 在游戏中不起作用.为什么?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用 SendInput API 来自动重复按键在游戏中而不必使用延迟.我希望按键尽可能快，所以我想避免使用像 Task.Delay 或 Thread.Sleep 方法这样的延迟.>
专注于Strum方法.
每当用户使用 Ctrl + B 热键时，下面的代码将按右 SHIFT 键 18 次.

为什么取消延迟后键盘输入不发送?
如何在不使用延迟的情况下发送键盘输入?
感谢任何帮助！
解决方案
这会改变结果吗?(注意，特意去掉了异步返回类型)
private static void Strum(){var 输入 = 新 []{新输入{类型 = InputType.KEYBOARD,U ={ki ={wScan = ScanCodeShort.RSHIFT}}},新输入{类型 = InputType.KEYBOARD,U ={ki ={wScan = ScanCodeShort.RSHIFT,dwFlags = KEYEVENTF.KEYUP}}}};for (var i = 0; i <18; i++){SendInput((uint)inputs.Length, 输入, INPUT.Size);}}I am trying to use The SendInput API to automatically press a key repeatedly in a game WITHOUT having to use delays. I want the key presses to be as quick as possible, so I'd like to stay away from using delays like the Task.Delay or Thread.Sleep methods.
Focus on the Strum method.
The code below will press the right SHIFT key 18 times whenever the user uses the Ctrl + B hot key.

As you can see, the Strum method contains 2 instances of the Task.Delay method. The code above will NOT work if I remove the 2 instances of the Task.Delay method.
Why does the keyboard input not send if I remove the delays?
How can I send the keyboard input without having to use the delays?
Any help is appreciated!

Does this change the result? (note, deliberately removed the async return type)
private static void Strum()
{
var inputs = new[]
{
new INPUT
{
type = InputType.KEYBOARD,
U =
{
ki =
{
wScan = ScanCodeShort.RSHIFT
}
}
},
new INPUT
{
type = InputType.KEYBOARD,
U =
{
ki =
{
wScan = ScanCodeShort.RSHIFT,
dwFlags = KEYEVENTF.KEYUP
}
}
}
};
for (var i = 0; i < 18; i++)
{
SendInput((uint)inputs.Length, inputs, INPUT.Size);
}
}
这篇关于除非我添加延迟，否则 SendInput 在游戏中不起作用.为什么?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
