# How to move camera in 2D with mouse

Hello I'm writing a 2d designer application and i thought about using GLControl for drawing.
I'm using this code to setup the view, so that the 0,0 coordinate is at the upper left corner of the control.

```GL.ClearColor(1f, 1f, 1f, 1f);
GL.MatrixMode(MatrixMode.Projection);
GL.Ortho(0, Width, Height, 0, 0, 1);
GL.MatrixMode(MatrixMode.Modelview);```

I want to be able to move the camera using mouse.
I tried to do it like that, but it doesnt work to good :P

```GL.ClearColor(1f, 1f, 1f, 1f);
GL.MatrixMode(MatrixMode.Projection);
GL.Ortho(0, Width, Height, 0, 0, 1);
if (MoveCamera) CameraHelper.CalcMovement();
GL.Translate(CameraHelper.GetMovmentX, CameraHelper.GetMovmentY, 0);
GL.MatrixMode(MatrixMode.Modelview);

public static class CameraHelper
{
private static int OldX = 0, OldY = 0, X = 0, Y = 0;
private static int MovementX = 0, MovementY = 0, MovementIncrement = 15;

public static int SetX { set { OldX = X; X = value; } }
public static int SetY { set { OldY = Y; Y = value; } }
public static int GetMovmentX { get { return MovementX; } }
public static int GetMovmentY { get { return MovementY; } }

public static void CalcMovement()
{
if ((Y - OldY) > 1) MovementY += MovementIncrement;
else if ((Y - OldY) < -1) MovementY -= MovementIncrement;
if ((X - OldX) > 1) MovementX += MovementIncrement;
else if ((X - OldX) < -1) MovementX -= MovementIncrement;
}
}```

Can someone provide a sample code for moving the camera with mouse in 2d space.
Soz for my English and OpenGL skills I just started learning :D
