[How to get mouse movement history?] 마우스 이동

The GetMouseMovePointsEx function retrieves a history of up to 64 previous coordinates of the mouse or pen.

Here is a demo that replays our mouse movements…

void ReplayMouseMovements()
{
	// Current cursor position
	POINT ptCurrentPoint = { 0 };
	GetCursorPos( &ptCurrentPoint );

	// Record marker, mouse co-ordinates prior(and including) to this point is returned in
	// the recorded array of points
	MOUSEMOVEPOINT mmpSamplePoint = { 0 };
	mmpSamplePoint.x = ptCurrentPoint.x;
	mmpSamplePoint.y = ptCurrentPoint.y;

	// Count of records expected, MSDN says max points returned will be 64
	// Anything greater than 64 results in error, API returns -1
	const DWORD dwMaxPoints = 64;

	// On return from function will hold last recorded mouse movements
	MOUSEMOVEPOINT mmpRecordedMovements[dwMaxPoints] = { 0 };
	const DWORD dwMode = GMMP_USE_DISPLAY_POINTS;

	// Get all points prior to sample point
	const int nPtCount = GetMouseMovePointsEx( sizeof( mmpSamplePoint ),
			&mmpSamplePoint,
			mmpRecordedMovements,
			dwMaxPoints ,
			dwMode ) ;

	// Loop through and animate
	for (int nIndex = 0; nIndex < nPtCount; nIndex++)
	{
		SetCursorPos( mmpRecordedMovements[nIndex].x, mmpRecordedMovements[nIndex].y );
		Sleep( 80 );
	}
} // End ReplayMouseMovements
