Cheat Engine

doKeyPress()
KeyUp()
KeyDown()
none of these can send keys to 3d games like csgo or other
only mouse_event() works but thats only for mouse how can i send keys to game

[exohaxor]

no one knows?

I'm also looking for the same
But the methods cheat engine state for key presses don't work
These are simple methods and I don't know any advanced method
So my knowledge is we have to use some other language like python or some advanced method in lua

Not all games accept input in the same manner. There are various ways input can be handled by an application/game, the methods exposed by Cheat Engine are just a very basic means of attempting to send input to another window.

doKeyPress, keyUp, and keyDown in CE call keybd_event which is a wrapper around 'NtUserSendInput'. Using SendInput with DirectInput, for example, requires additional setup/adjustments to the params passed to the API. The way CE calls it at the moment does not adjust the parameters properly for that instance.

There is also games that take input from the window message handler from messages such as:
- WM_CHAR
- WM_KEYDOWN
- WM_KEYUP

SendInput will not work with these messages.

Another method is via RawInput commands. Most games that use RawInput generally only use it for mouse input or controllers, but keyboard is able to be done via it as well.

For CE related scripts, ideally it would be useful if Dark Byte could add support for custom params added to doKeyPress/keyUp/keyDown to adjust the params of SendInput calls. Up to him ultimately to add it or you can make a pull request on GitHub with the proper adjustments to not break the current API layout while adding more functionality.

For DirectInput, if using SendInput you need to adjust the flags passed to include 'KEYEVENTF_SCANCODE'. The key id will then become the proper DirectInput key id instead of the VK code.

(One last thing to keep in mind with this, using API such as SendInput does mark the key as injected. So certain games that monitor for external input for cheating can tell the API call was used.)

so can we send DirectInput with vanilla CE?
