Visible

The Visible property on a Circle controls whether the Circle is rendered or not. Invisible Circles will still perform collision properly, so this property does not need to be set if using Circles purely for collision. Rendered circles will render their outline using their Color property. Circles cannot be filled-in, only their outline will render. Setting Visible to true may result in a Circle being added to the ShapeManager. For more information about how Visible results in ShapeManager membership, see the ShapeManager page.
