Trying to simulate a mouse click in a game that uses DI

I'm trying to simulate a mouse click in a game that uses Direct Input. I really don't want to make a hook or anything like that at this point but I do need to make this click only affect the game window.
Thanks for any advice.
Edit: Forgot to add I'm using c++ to do this.

Try using SendInput and PostMessage. Search on MSDN for documentation and examples.

Sadly them don't really work. SendInput can work with direct input apps using the direct input scan codes but it's global and i cannot use it with an inactive window.
I really need a way to send mouse input into the inactive game window.

Unfortunately, the only decent way to do that would be to make use of hooks.
The easy way to do it would be to get a D3D hook starter kit (search for this on
www.gamedeception.net). You'll have 99% of the work done for you there; just need to modify the hook for the mouse and/or call the original in your own code.

Thanks for the reply. I'll look into it.

I wish there was a tutorial that ddn't have so much in it already. I'm still very new to this and need something to start with not a full working hack pushed in my face.
I'm gonna try to dig around more but if you happen to stumble across something thats a very plain dinput mouse hook, please send it my way.

The starter kit I mentioned just provides working hooks to all the functions which you need to fill in yourself. Trust me, you don't want to do all that work yourself. Even though you think you might only need one or two functions, you would still have to hook every function for DirectX because it is object oriented, unlike OpenGL. It's not worth the time.

I'll try to figure it out but I think for my first c++ hack I may have to settle for a bit less. How do you go about sending mouse input to active windows? I can sends keyboard events and stuff but haven't got the mouse input part yet.
Edit: mouseLClick(); This sends input to the game just fine.

This is how it's done in MicroMacro
Code: Select all
void MouseDevice::leftHold(unsigned int modifier)
{
if( attachedHwnd ) {
LPARAM lparam = MAKELPARAM(vMouseX, vMouseY);
PostMessage(attachedHwnd, WM_LBUTTONDOWN, MK_LBUTTON, lparam);
} else {
INPUT inp;
memset(&inp, 0, sizeof(INPUT));
inp.type = INPUT_MOUSE;
inp.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
SendInput(1, &inp, sizeof(INPUT));
}
}
void MouseDevice::leftRelease(unsigned int modifier)
{
if( attachedHwnd ) {
LPARAM lparam = MAKELPARAM(vMouseX, vMouseY);
PostMessage(attachedHwnd, WM_LBUTTONUP, MK_LBUTTON, lparam);
} else {
INPUT inp;
memset(&inp, 0, sizeof(INPUT));
inp.type = INPUT_MOUSE;
inp.mi.dwFlags = MOUSEEVENTF_LEFTUP;
SendInput(1, &inp, sizeof(INPUT));
}
}
void MouseDevice::leftClick(unsigned int modifier)
{
leftHold(modifier);
Sleep(delay);
leftRelease(modifier);
}
Since you're not using attached input, just use the SendInput information.

Thanks a bunch, That replains why my keyboard wasn't working 100% too... -.- Release the keys!
Attached input would be where it sends the input directly to a window i guess?

That is correct.

Thanks again.
I've got most of the base functions done now for reading and writing memory and for my keyoard and mouse.
