[visionegg] Re: pygame.mouse.get_pos()

bottom right?
I think you might mean bottom left?
either way, it depends on what you want to do.

 the line
 y = screen.size[1]-y # convert to OpenGL coords
is taking the vertical position of the mouse on the screen and flipping the coordinates, remember opengl coordinates start in the bottom left, not the upper left. 

Are you trying to change the way objects are placed on the screen?
I have a big pile of code for doing things that sounds like they are related to this, but I'm not sure what you want to do. 
hope I can help

Hello all,
As I have been going through the programming, I have run into a major stumbling block when it comes to pygame.mouse.get_pos().
According to the description , pygame.mouse.get_pos() takes the coordinate mapping system from the upper left hand corner of the display. Is there anyway to make this map out the coordinates from the bottom right hand corner, so that standard x-y coordinates can be applied (such as in the positioning of text)? 

For reference here's how the program reads:
 just_current_pos = mouse_position
    (x,y) = pygame.mouse.get_pos()
    y = screen.size[1]-y # convert to OpenGL coords
    mouse_position = (x,y)
    if just_current_pos != mouse_position:
        last_mouse_position = just_current_pos
My attempts at changing the coordinates mathematically (y= -y +600) have failed, either by having the display outside of the viewing screen, or my personal favorite, inverting the mouse all-together. I've tried manipulating the y= line as well as the mouse_position line, all to no avail. 

Any help or suggestions would be greatly appreciated.

Thanks,
Jeff
