Winapi mouse_event错误的坐标

Question

I tried to make an autoClicker that record where I put my mouse and then click the exact coordinated but in the end it clicks the same number of clicks on the last spot that my mouse was.

const int WAIT_INTERVAL = 5;
const int CLICK_POINTS = 5;
POINT mouse[CLICK_POINTS];
int clicks;
bool didGetPos;

for (int i = 1; i <= CLICK_POINTS; i++)
    {
        cout << i << " spot" << endl;
        Sleep(3000);
        didGetPos = GetCursorPos(&mouse[i - 1]);

        if (!didGetPos)
        {
            break;
        }
    }

    if (didGetPos)
    {
        for (int i = 0; i < CLICK_POINTS; i++)
        {
            for (int j = 0; j < clicks; j++)
            {
                mouse_event(MOUSEEVENTF_LEFTDOWN, mouse[i].x, mouse[i].y, 0, 0);
                mouse_event(MOUSEEVENTF_LEFTUP, mouse[i].x, mouse[i].y, 0, 0);
            }
        }
    }

Answer 1

You did not include the MOUSEEVENTF_ABSOLUTE flag. The documentation says:

The dx and dy parameters contain normalized absolute coordinates. If not set, those parameters contain relative data: the change in position since the last reported position. This flag can be set, or not set, regardless of what kind of mouse or mouse-like device, if any, is connected to the system.

You are passing absolute coordinates and so need to include the MOUSEEVENTF_ABSOLUTE flag.

Of course you should heed the documentation and stop using this superseded function. Use SendInput .
