Windows SendInput function

[HezkoreParticipant]

I’m working on a front-end for my arcade machine.
I need to translate my custom made gamepad into mouse movements.
I’m trying to figure out how Window’s SendInput function works, but I’m really confused..

Here’s the MSDN link to SendInput.

Any help?

Can’t you just use MX2’s built-in event handling mechanisms to generate mouse movement events? Eg:

If event.Type = EventType.MouseMove Print "Mouse moved." Endif End End Function Main() New AppInstance New MyWindow App.Run() End

Hmm, my mouse doesn’t move when I run that code.
But it does print “Spacebar pressed. Mouse moved.”.
I need to actually move the mouse pointer around on the screen.
Triggering the mouse event in M2 sadly isn’t enough.

My arcade machine doesn’t have a mouse, just a gamepad I’ve built myself.
Sometimes I do need a mouse though, so I figured I’d code a “mouse mode” or something, where I can control the mouse via the gamepad itself.

* Hide the “actual” mouse cursor. Draw a “sprite” mouse cursor instead.
* Read your gamepad input coordinates.
* Translate the coordinates to a screen location vector.
* Draw the mouse cursor sprite at the vector.
* Trigger an EventType.MouseMove event, including the vector.
* Handle the event in the OnMouseEvent method.

Easy peasy?!

Or I still misunderstand your objectives… Forgive me if that’s the case.

I need to click Windows buttons, or drag desktop icons, or click Windows text fields, browse the web etc.
The mouse isn’t for my stuff, I just need to control it from my code to interact with lots of other applications.

[impixiParticipant]

Ah, I see. Then yes, you’ll need something lower level, probably coded in C/C++. Good luck.

Directly with SDL function : SDL_WarpMouseGlobal:Void( x:Int, y:Int )
Remarks : This function generates a mouse motion event. A failure of this function usually means that it is unsupported by a platform.

[HezkoreParticipant]

SDL_WarpMouseGlobal actually works for Windows stuff.
Sadly, it doesn’t seem to register in any other apps.
But it’s something at least!
Big thanks.
