Radar Grid

The Radar Grid turns the floor into a radar screen. Concentric range rings and radial spokes fill a round disc framed by a bezel with tick marks and a crosshair. A sweep arm turns around the centre, leaving a fading green trail, and contacts scattered across the scope flare up as the arm passes over them and then fade until it comes round again.

How it works

The disc is drawn in polar terms: rings at a fixed spacing out from the centre and spokes at equal angles around it, with every few rings drawn as a heavier major ring. The radius of the disc is the Fade Distance, so the scope keeps its frame while the field inside it fades. Each blip sits in its own ring-and-spoke sector, and its glow is measured from the moment the arm last crossed it.

Settings

• Spokes is the number of radial lines; 0 removes them.
• Sweep Width is the length of the trail behind the arm, as a share of a full turn; 0 hides the sweep.
• Blip Density is the chance that a sector holds a contact.
• Line Mode: Ripple sends ping rings out from the centre, Scan lights the spokes one after another like a sector scan.
• Anim Speed sets how fast the arm turns.
