Hello

How do you move the mouse. I have a camera looking straight down from the top and only zoom in/out is supported (2D game).

This is how I setup the environment:

```
// Set viewport
glViewport( 0, 0, width, height );
// Clear color and depht buffers
glClearColor( 0.0f, 0.0f, 0.0f, 0.0f );
glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
// Set up projection matrix
glMatrixMode( GL_PROJECTION ); // Select projection matrix
glLoadIdentity(); // Start with an identity matrix
gluPerspective( // Set perspective view
64.0, // 65.0 Field of view = 65 degrees
(double)width/(double)height, // Window aspect (assumes square pixels)
1.0, // Near Z clipping plane
400.0 // Far Z clippling plane
);
// Set up modelview matrix
glMatrixMode( GL_MODELVIEW ); // Select modelview matrix
glLoadIdentity(); // Start with an identity matrix
gluLookAt( // Set camera position and orientation
0.0, 0.0, 10.0, // Camera position (x,y,z)
0.0, 0.0, 0.0, // View point (x,y,z)
0.0, 1.0, 0.0 // Up-vector (x,y,z)
);
```

Now every time I draw, I also call a function to draw the mouse pointer. This function looks like this:

```
void DrawMouse(
)
{
int x, y;
glfwGetMousePos(&x, &y);
// Now draw the quad
glBegin( GL_LINES );
glColor3f( 1.0f, 0.431f, 0.647f );
glVertex3f( x/1680.0, y/-1050.0, 0.0f );
glColor3f( 1.0f, 0.431f, 0.647f );
glVertex3f( (x/1680.0)+0.5f, (y/-1050.0)+0.5f, 0.0f );
glEnd();
}
```

Now, my question is:

- Is this the right way to introduce mouse support? (If not how)
- If this is the way to go, how do I solve the zoom problem. The further away I am zoomed out, the slower the mouse moves. What operations do I have to do to adjust for the zoom? (I am not that great with matrices)

Tnx
