C++ mouse_event mouse look

I have the following code for c++

I am trying to make a "mouse look" function so I can use it to control a video game I play, now, the mouse clicks work fine. but I can't get holding down right mouse button and move mouse to look around to work. Did I miss something?

thx

#include <iostream>
#include <windows.h>
#include <ctime>
using namespace std;

void main()
{
	Sleep(3000);

	INPUT input;
	input.type = INPUT_MOUSE;
	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));

	input.mi.dx = 10;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_MOVE;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));

	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_RIGHTUP;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));
		
	return;
}

Is there a way to combine mouse movement with clicking? As in, use one line of this
SendInput(1, &input, sizeof(input));

but with moving the mouse while clicking it or holding it down?

thx

Hmm, there must a tiny thing i got wrong here:

I think LPINPUT is the proper type! but it says the expression must include class type.

#include <iostream>
#include <windows.h>
#include <ctime>
using namespace std;

void main()
{
	Sleep(3000);

	INPUT input[3];

	input[0].type = INPUT_MOUSE;
	input[0].mi.dx = 0;
	input[0].mi.dy = 0;
	input[0].mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	input[0].mi.time = 10;
	input[0].mi.time = 0;
	// SendInput(1, &input, sizeof(input));
	
	Sleep(50);
	input[1].type = INPUT_MOUSE;
	input[1].mi.dx = 100;
	input[1].mi.dy = 0;
	input[1].mi.dwFlags = MOUSEEVENTF_MOVE;
	input[1].mi.time = 10;
	//SendInput(1, &input, sizeof(input));

	Sleep(50);
	input[2].type = INPUT_MOUSE;
	input[2].mi.dx = 0;
	input[2].mi.dy = 0;
	input[2].mi.dwFlags = MOUSEEVENTF_RIGHTUP;
	input[2].mi.time = 0;
	///SendInput(1, &input, sizeof(input));

	SendInput(3, &input, sizeof(input));

	//Sleep(50);
	/*
	input.type = INPUT_MOUSE;
	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_LEFTUP;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));

	input.type = INPUT_MOUSE;
	input.mi.dx = 0;
	input.mi.dy = 0;
	input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
	input.mi.time = 10;
	input.mi.time = 0;
	SendInput(1, &input, sizeof(input));
	*/
	return;
}

Alter the sequence of left mouse click

      input.type = INPUT_MOUSE;
      input.mi.dx = 0;
      input.mi.dy = 0;
      input.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
      input.mi.time = 10;
      input.mi.time = 0;
      SendInput(1, &input, sizeof(input));

input.type = INPUT_MOUSE;
      input.mi.dx = 0;
      input.mi.dy = 0;
      input.mi.dwFlags = MOUSEEVENTF_LEFTUP;
      input.mi.time = 0;
      SendInput(1, &input, sizeof(input));

Moreover in code small change is needed for right mouse button, as follows.

      input.mi.dx = 10; <= CHANGE FROM 0 to 10 as per you code shown in first place.
      input.mi.dy = 0;
      input.mi.dwFlags = MOUSEEVENTF_RIGHTUP;
      input.mi.time = 0;
      SendInput(1, &input, sizeof(input));

Sorry I should have clarified this:

Instead of sending 3 events of this in 3 separate sendinput() , I am trying to create an array of INPUT and use sendinput only once, as described here:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms646310(v=vs.85).aspx

UINT WINAPI SendInput(
  _In_ UINT    nInputs,
  _In_ LPINPUT pInputs,
  _In_ int     cbSize
);

Type: LPINPUT
An array of INPUT structures. Each structure represents an event to be inserted into the keyboard or mouse input stream.

Open in new window

So, here is what I have:

#include <iostream>
#include <windows.h>
#include <ctime>
using namespace std;

void main()
{
	Sleep(3000);

	INPUT input[3];

	input[0].type = INPUT_MOUSE;
	input[0].mi.dx = 0;
	input[0].mi.dy = 0;
	input[0].mi.dwFlags = MOUSEEVENTF_RIGHTDOWN;
	input[0].mi.time = 10;
	input[0].mi.time = 0;
	// SendInput(1, &input, sizeof(input));
	
	Sleep(50);
	input[1].type = INPUT_MOUSE;
	input[1].mi.dx = 100;
	input[1].mi.dy = 0;
	input[1].mi.dwFlags = MOUSEEVENTF_MOVE;
	input[1].mi.time = 10;
	//SendInput(1, &input, sizeof(input));

	Sleep(50);
	input[2].type = INPUT_MOUSE;
	input[2].mi.dx = 0;
	input[2].mi.dy = 0;
	input[2].mi.dwFlags = MOUSEEVENTF_RIGHTUP;
	input[2].mi.time = 0;
	///SendInput(1, &input, sizeof(input));

	SendInput(3, &input, sizeof(input));


	return;
}

Yet, the compiler gave me this error message:

argument of type "INPUT (*)[3]" is incompatible with parameter of type "LPINPUT"

Open in new window

So I didn't formulate the array properly.
What's the right way to do it?
Thanks!
