Half circle near the edge of the screen

[Carlos]

Is it possible to draw a half circle near the edge of the screen? I'm trying to put a full circle near it, but it when it gets off the screen it dissapears completely.

This is what I'm trying to achieve:




Thank you in advance.

Are you using Vertex2ii to draw the circle? If so, that's probably the problem, because Vertex2ii() cannot handle negative coordinates.

So instead of

GD.Vertex2ii(circle_x, circle_y);
use:

GD.Vertex2f(16 * circle_x, 16 * circle_y);
The book covers this on page 55.

Thank you, this works perfectly!
